  Never use a flammable spray, such as hair spray or lacquerer paint, near the unit. It may cause a fire.

• Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to minimize the risk of ignition

• When repairing the refrigerating system, comply with the following precautions prior to conducting work on the system:
  – shall be undertaken according to controlled procedures so as to minimize the risk of the presence of flammable gases or vapors while the work is being performed.
  – All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided.
  – The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is aware of potentially toxic or flammable environment. Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
  – If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing equipment shall be available and easily accessible. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.
  – When carrying out work in relation to a refrigerating system that involves exposing any pipe work, no sources of ignition shall be used in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the site of installation, repair, or removal and disposal of the unit, during which refrigerant can possibly be released into the surrounding space. Prior to beginning work, the area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. “No Smoking” signs shall be clearly displayed.

• Ensure that the area is in the open or that it is adequately ventilated before opening the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the surroundings.

• Where electrical components are being changed, they shall be fit according to their purpose and to the correct specification. At all times the manufacturer’s maintenance and service guidelines shall be followed. If in doubt, consult the manufacturer’s technical department for assistance. The following checks shall be applied to installations using flammable refrigerants:
  – The actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are installed;
  – The ventilation machinery and outlets are operating adequately and are not obstructed;
  – If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;
  – Equipment marking must remain visible and legible. Markings and signs that are illegible shall be corrected; – Refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any substances which may corrode refrigerant containing components, unless the components are constructed of materials that are inherently resistant to corrosion or are suitably protected against corrosion.

• Repair and maintenance of electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until the fault has been dealt with satisfactorily. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be reported to the owner of the equipment so that all parties are advised. Initial safety checks shall include:
  – That capacitors are discharged: this shall be done in a safe manner to avoid the possibility of sparking;
  – That no live electrical components and wiring are exposed while charging, recovering or purging the system;
  – That there is continuity of grounding.

• When repairing sealed components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any removal of sealed covers, etc.

• If it is absolutely necessary to have an electrical supply to the equipment during servicing, then a permanently operating form of leak detection shall be installed at the most critical point to warn of a potentially hazardous situation.

• Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not altered in such a way that the level of protection is affected. This shall include damage to cables, an excessive amount of connections, terminals not made to their original specification, damage to seals, incorrect fitting of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no longer prevent the ingress of flammable materials. Replacement parts shall conform with the manufacturer’s specifications.

• Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use.

• Intrinsically safe components are the only types that can be worked on while live in the presence of flammable gases. The test apparatus shall be at the correct rating.

• Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant which has leaked into the surroundings.

• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

• The refrigerant charge shall be recovered into the correct recovery cylinders. The system shall be “flushed” with OFN to render the unit safe. This process may need to be repeated several times. Do not use compressed air or oxygen for this task.

• Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until a working pressure is achieved, then venting to the surroundings, and finally pulling down to a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used, the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital if brazing operations on the pipework are to take place.

• Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant they contain.

• Cylinders shall be kept upright.
  Ensure that the refrigeration system is grounded prior to charging the system with refrigerant.

• Label the system when charging is complete (if it is not already labeled).
  Take extreme care not to overfill the refrigeration system.

• Prior to recharging the system it shall be pressure tested with OFN. The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

• Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its detail.
  It is recommended that all refrigerants are recovered safely. Prior to the task being carried out, an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. It is essential that electrical power is available before the task is commenced.

• Once the unit has stopped running, do not disconnect the power immediately. Wait for at least 10 minutes.

2.2.2 Cooling and heating operations
The indoor units in the air conditioner can be controlled separately, but the indoor units in the same system cannot operate in the heating and cooling modes at the same time.
When the cooling and heating operation conflict with each other, the indoor units which are running in cooling or fan mode will stop and will display the message standby or no priority on the control panel. Those indoor units which are running on heating mode will run continuously.
If the air conditioner administrator has set the running mode, then the air conditioner cannot run in any mode other than the mode presented. Standby or no priority will be displayed on the control panel.

2.2.3 Features of heating operation
About heating capacity

Once the unit starts, it takes some time for the room temperature to rise, as the unit uses a hot air circulation system to heat the room.
The indoor fan motor will automatically stop running so as to prevent cold air from coming out of the indoor unit when the heating operation starts. This process will take some time, which depends on the indoor and outdoor temperature. This is not a malfunction.

When there is a drop in the external temperature, the heating capacity decreases. If this happens, please use other heating equipment and units at the same time. (Make sure the room is well ventilated if you are using equipment that produces fire.) Do not place any equipment that may produce a fire where the air outlets of the unit are or below the unit itself.
And need to perform the following operations to prevent the heating capacity from dropping or prevent cold air from coming out of the system.

Defrost operation
While heating, as the outdoor temperature decreases, frost may form on the heat exchanger in the outdoor unit, making it more difficult for the heat exchanger to heat up the air. The heating capacity will decrease, and the system will need to be defrosted in order to provide sufficient heat to the indoor unit. At this point, the control panel of the indoor unit will show that a defrost operation is occurring.

NOTE

• The motor in indoor unit will continue running for about 40 seconds to remove residual heat when the indoor unit receives a shutdown command while heating.
• If the air conditioner malfunction occurs because of interferences, please disconnect the power from the air conditioner, then turn it on again.

2.2.4 Power cuts
If there is a power outage while the unit is running, the unit will automatically restart its operation when the power supply resumes.

Table 4-5 Compressor driver error code

Table 4-6 Fan motor error code

Table 4-7 Status code

4.4 Fault Symptom: Non Air Conditioning Issues

Symptom 1: The system does not operate

• The air conditioner does not start immediately after the ON/OFF button on the remote controller is pressed.
  If the operation lamp lights up, the system is in normal condition. To prevent overloading of the compressor motor, the air conditioner starts 3 minutes after it is turned on.

• If the operation lamp and the “PRE-DEF indicator (cooling and heating type) or fan only indicator (cooling only type)” light up, it means you must choose the heating mode. When just starting, if the compressor has not started, the indoor unit displays “anti cold wind” protection because the air outlet temperature is too low.

Symptom 2: The system switches into the fan mode during cooling

• In order to prevent the indoor evaporator from frosting, the system will switch into fan mode automatically, and return to the cooling mode soon.
• When the room temperature drops to the set temperature, the compressor goes off and the indoor unit switches to fan mode; when the temperature increases, the compressor starts again. It is same in heating mode.

Symptom 3: White mist comes out of a unit

Symptom 3.1: Indoor unit

When humidity is high during cooling operation. If the interior of an indoor unit is extremely contaminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the interior of the indoor unit. Ask your dealer for details on cleaning the unit. This operation requires a qualified service person

Symptom 3.2: Indoor unit, outdoor unit

When the system switches over to heating operation after defrost operation, moisture generated by defrosting becomes steam and is exhausted.

Symptom 4: Noise of air conditioners cooling

Symptom 4.1: Indoor unit

• A continuous low “shah” sound is heard when the system is in cooling operation or stops.
  When the drain pump (optional accessories) is in operation, this noise is heard.

• A “pishi-pishi” squeaking sound is heard when the system stops after heating operation.
  Expansion and contraction of plastic parts caused by temperature changes can make this noise.

Symptom 4.2: Indoor unit, outdoor unit

• A continuous low hissing sound is heard when the system is in operation.
  This is the sound of refrigerant gas flowing through both indoor and outdoor units.

• A hissing sound is heard at the start or immediately after stopping operation or defrost operation.
  This is the noise of refrigerant caused by flow stops or flow changes.

Symptom 4.3: Outdoor unit

• When the tone of operating noise changes, the noise is caused by the change of frequency.

Symptom 5: Dust comes out of the unit

When the unit is used for the first time in a long time, it is because dust has gotten into the unit.

Symptom 6: The units give off odors

The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it again.

Symptom 7: The outdoor unit fan does not spin.

During operation, the speed of the fan is controlled in order to optimize product operation.

4. PREPARATIONS BEFORE INSTALLATION

4.1 Choosing and Preparing the Installation Site

4.1.1 Site requirements

Please refrain from installing the unit in the following places, or malfunction of the machine may occur:

• A place where there is combustible gas leakage.
• A place where there is a lot of oil (including engine oil).
• A place where there is salty air (locations near the coast)
• A place where there is caustic gas (sulfide, for example) present in the air (near a hot spring)
• A place where the heated air expelled out from the outdoor unit can reach your neighbor’s window.
• A place where the noise interferes with your neighbors’ everyday life.
• A place that is too weak to bear the weight of the unit
• An uneven place.
• A place with insufficient ventilation.
• Near a private power station or high frequency equipment.
• Install the indoor unit, outdoor unit, power cord and connecting wire at least 1 m away from a TV set or radio to prevent noise or picture interference.
• Install the unit in a place that can offer enough space for installation and maintenance. Don’t install it in a place that has high requirements regarding noise, such as in a bedroom.

CAUTION

• Install the outdoor unit at a place where discharge air is not blocked.
• When an outdoor unit is installed in a place that is frequently exposed to strong winds like a coast or on the high story of a building, ensure normal fan operation by using a duct or a wind shield.
• When installing the outdoor unit in a place that is constantly exposed to a strong wind such as the upper floors or rooftop of a building, apply the windproof measures referring to the following examples.

Supposing the wind direction during the operation season of the discharge port is set at a right angle to the wind direction.

CAUTION

• Keep a distance of 2000mm or more between the unit and the wall surface when the discharge port faces to the wall of the building.

4.2 Selecting and Preparing the Refrigerant Piping

4.2.1 Refrigerant piping requirements

NOTE

The R410A refrigerant pipeline system must be kept strictly clean, dry and sealed.

Cleaning and drying: prevent foreign objects (including mineral oil or water) from mixing into the system.

Seal: R410A does not contain fluorine, does not destroy the ozone layer, and does not deplete the ozone layer that protects the earth from harmful ultraviolet radiation. But if it is released, R410A can also cause a slight greenhouse effect. Therefore, you must pay special attention when you check the quality of the installation seal.

The piping and other pressure vessels must comply with the applicable laws and be suitable for use with the refrigerant. Use only phosphoric acid deoxidized seamless copper for the refrigerant piping.

Foreign objects in the pipes (including lubricant used during pipe bending) must be ≤ 30 mg/10 m.
Calculate all piping lengths and distances.

4.2.2 Design considerations

NOTE

• The amount of brazing required should be kept to a minimum.
• As bends cause pressure loss when transporting refrigerant, the fewer bends in the system, the better it is. Piping length needs to take the equivalent length of bends into account (the equivalent length of each branch joint is 0.5 m).
• On the two inside sides of the first branch joint, the system should, as far as possible, be equal in terms of the number of units, total capacities and total piping lengths.

4.2.3 Piping and component definition
Table 4-2

• Schematic diagram of the allowable length and height difference for refrigerant piping

4.2.4 Allowable length and height difference for refrigerant piping

Note

It is recommended that an oil return bend with dimensions as specified in Figure 4-8 is set every 10 m in the gas pipe of the main pipe.

4.2.5 Refrigerant pipe selection

Select refrigerant pipe and branch joint according to Table 4-4 to 4-7.

NOTE

• Branch header can also be selected to connect pipes and indoor units. Meanwhile, the relevant requirements in the Owner’s Manual and Installation manual must be followed
• The selection of branch header depends on the quantity of branches it connects to.
• Branches and other branch heads cannot be installed downstream of the initial head branch.

Main pipes (L1) and first branch joint kit (A) according to the outdoor unit

Table 4-4

NOTE

When the total equivalent piping length of liquid + gas side is ≥ 90m, it must increase the size of main gas pipe as shown in Table 4-5.

Pipe diameter and branch joint kits between the outdoor unit and indoor units according to downstream indoor unit

NOTE

• The corresponding maximum values listed in
  Table 4-4, Table 4-5 and Table 4-6 should be used as the main pipe (L1) size and the first branch joint (A) size.

• Choose indoor unit main pipes and branch joints between the first branch joint and indoor units from the above table in accordance with the total capacity of all the indoor units connected downstream.

Indoor unit auxiliary pipe (a~f)

Table 4-7

The pipe thickness of the refrigerant piping shall comply with the applicable legislation.

The minimal pipe thickness for R410A piping must be in accordance with the table below.

NOTE

• Material: Only seamless phosphorus
  -deoxidized copper piping that complies with all applicable legislation should be used.
• Thicknesses: Temper grades and minimum thicknesses for different diameters of piping should comply with local regulations.
• Design pressure of R410A refrigerant is 4.3 MPa (43 bar).

An example of refrigerant piping selection

The example below illustrates the piping selection procedure for a system consisting of an outdoor unit (16kW) and 6 indoor units (2.2 kW×1+2.8 kW×5), as shown in Figure 4-9. The system’s total equivalent length of all liquid and gas pipes is not more than 90m.

Select main pipe (L1) and first branch joint (A)
The outdoor unit capacity is 16 kW, and the system’s total equivalent length of all liquid and gas pipes is not more than 90m. So refer to Table 4-4, the main gas liquid pipe size is Φ19.1 and Φ9.52 respectively. The first branch joint A is FQZHN-01D.

Select indoor main pipe (L2~L5) and branch joint (B~E)

The downstream indoor units of L2 are N1 to N2, with the capacity of 5.6 kW. Referring to Table 4-6, the gas and liquid pipe size of L2 are Φ12.7 and Φ6.35 respectively, and the branch joint B is FQZHN-01D.

Similarly, the pipe size of L3 is Φ15.9 and Φ9.52, the pipe size of L3 and L4 is Φ15.9 and Φ9.52, and the branch joint B~E are all FQZHN-01D.

Select the indoor unit auxiliary pipe (a to i)
The capacity of indoor unit N1 to N6 is all less than 6.3 kW. According to Table 4-7, the pipe size from a to f is respectively Φ12.7 and Φ6.35.

5. OUTDOOR UNIT INSTALLATION

5.1 Preparing the Structure for Installation

• Make concrete foundation according to the specifications of the outdoor units (refer to Figure 5-1).
• Fasten the feet of this unit with bolts firmly to prevent it from collapsing in the event of an earthquake or strong winds (refer to Figure 5-1).

5.2 Things to Note When Connecting the Refrigerant Piping

Caution

• Take appropriate precautions to prevent refrigerant leakage and ventilate the area immediately if the refrigerant leaks, as high concentration of R410A refrigerant in an enclosed area can cause poisoning or fire.
• Refrigerant must be recovered. Do not release it into the environment. Use professional fluorine extraction equipment to extract the refrigerant from the unit.

NOTE

• Make sure the refrigerant piping is installed in accordance with applicable laws.
• Make sure the piping and connections are not placed under pressure.
• Before brazing, the refrigerant piping should be flushed with oxygen free nitrogen (OFN) to remove dust, moisture and other particles.
• Never use outdoor unit refrigerant.
• Do not open the stop valves until confirming that all the piping connections have been completed and there are no gas leaks in the system.

5.3 Refrigerant Piping Connection

CAUTION

• Please be careful to avoid the components while connecting to the connecting pipes.
• Oxygen free nitrogen (OFN) shall be purged through the system both before and during the brazing process.

The indoor and outdoor connecting pipe interface and power line outlet.

Various piping and wiring patterns can be selected, such as exiting from the front, the back, the side, and undersurface, etc.

(The following displays the locations of several piping and wiring knock-off interfaces)

The connection method of flaring(8/10/12/14/16 kW)

CAUTION

• Side out pipe: please remove the L-shape metal plate, otherwise wiring cannot be completed.
• Back outlet pipe: please wipe off the piping support rubber blanket beside the inner outlet pipe cover of the machine while the pipe exits from the back.
• Front outlet pipe: cut the frontal hole of the pipe-outlet plate. The method for the outlet pipe is the same as the back outlet pipe.
• Undersurface outlet pipe: the knock out should from inside to outside, and then piping and wiring should be fed through this. Make sure that the fat connecting pipe exits through the largest hole, otherwise the pipes will rub together. Please do the moth proofing for the created hole, to avoid pests from entering into and destroying the components.

5.4 Leak Detection
Electronic leak detectors shall be used to check whether air leaks at each joint.

• A and B indicate check valves of ODU.
• C and D indicate IDU connecting pipe ports.
• All of the connection ports between the branch header and refrigerant pipe.

Warning

• Under no circumstances shall potential sources of ignition be used to search for or detect refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.

5.5 Heat Insulation

Carry out heat insulation treatment for the pipes at the gas and liquid sides respectively. Pipes on the liquid and gas sides have a low temperature during cooling. Take sufficient insulation measures to prevent condensation (see Figure 5-8).

The gas pipe must be treated with the closed-cell foam insulation material, which is rated at a non-flammable level of B1 and heat resistance of over 120°C.

When the outer diameter of the copper pipe is not greater than Φ12.7 mm, the thickness of insulation layer should be greater than 15mm.

When the outer diameter of the copper pipe is equal to or greater than Φ15.9 mm, the thickness of the insulation layer should be greater than 20 mm.

The attached insulation material for the part of the IDU where the pipe connects must undergo heat insulation treatment without gaps.

5.6 Airtight Test
Air tightness test – OFN must be used.
Increase the pressure from the liquid pipe and gas pipe to 4.0 MPa at the same time (not exceeding 4.0 MPa). If the pressure does not drop in 24 hours, the test is passed.
When the pressure drops, check the leakage position.
After you make sure that there is no leakage, discharge the nitrogen.

Caution

• Never use oxygen, combustible gas, or poisonous gas in the air tightness test.
• To prevent damage to the equipment, the pressure must not be held for too long.

5.7 Air Purge with Vacuum Pump

• Use a vacuum pump that can evacuate the pipe to a pressure of less than -100.7 kPa (5 Torr, -755 mmHg). When the pump is stopped, do not let the pump oil flow back into the refrigerant pipe.
• The liquid and gas pipes should be evacuated with a vacuum pump for more than two hours to a pressure of less than -100.7kPa.
• Then, place the pipes at pressure of less than -100.7 kPa for more than one hour, and check whether the reading of the vacuum gauge rises. (If the reading rises, there is residual water or gas leakage in the system. The leakage must be checked and solved and the test should be performed again.)
• Water may enter into pipes under the following circumstances: the installation is carried out in a rainy season and the installation period is long; the pipes are condensed inside; rainwater enters the pipes.
• After the above vacuum drying of two hours, use nitrogen to increase the pressure to 0.05 MPa (vacuum breaking), and use a vacuum pump to decrease the pressure to lower than -100.7kPa or below and hold the pressure for one hour (vacuum drying).
• If the pressure cannot be decreased to lower than -100.7 kPa after two-hour vacuumizing, repeat the vacuum breaking and vacuum process. After that, place the vacuum pipes for one hour, and then check whether the reading of the vacuum gauge rises.

Caution

• Use a vacuum pump to perform the vacuumizing process. Do not use refrigerant gas to discharge air.
• Use a vacuum pump that can vacuumize the pipe to a pressure of less than -100.7 kPa (5 Torr, -755 mmHg). When the pump is stopped, do not let the pump oil flow back into the refrigerant pipe.
• In order to prevent the entry of impurities, the R410A special tool must be used to ensure the compression strength. Use a filling hose with a top rod to connect to the maintenance access of the check valve or the refrigerant filling port.

5.8 Refrigerant Amount to be Added

Warning

• Use only R410A as the refrigerant. Other substances may cause explosions and accidents.
• R410A contains fluorinated greenhouse gases, and the GWP value is 2088. Do not discharge the gas into the surroundings.
• When charging the refrigerant, make sure you wear protective gloves and safety glasses. Be careful when you open the refrigerant piping.
• Charge the refrigerant only after the system has not failed the gas tightness tests and vacuum drying.
• Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
• Add the refrigerant amount according to the calculation results. Extreme care shall be taken not to overfill the refrigeration system.
• The system shall be leak tested on completion of charging but prior to commissioning. A follow up leak test shall be carried out prior to leaving the site.

NOTE

• Make sure all connected indoor units have been identified.
  Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.

• Cylinders shall be kept upright.

• Label the system when charging is complete (if it is not already labeled).

5.8.1 Calculating additional refrigerant charge
The additional refrigerant charge required depends on the lengths and diameters of the outdoor and indoor liquid pipes . Table 5-1 show the additional refrigerant charge required under different conditions.

Additional refrigerant charge amount R1 (according to liquid pipe lengths and diameters)

The additional refrigerant charge amount (R1) is obtained by adding the additional charge requirements for each of the outdoor and indoor liquid pipes, as in the following formula, where L1 to L4 represent the equivalent lengths of the pipes of different diameters.

Additional refrigerant charge amount R1 (kg) = L1 (Φ 6.35) × 0.022 + L2 (Φ9.52) × 0.054 + L3 (Φ12.7) × 0.110 + L4 (Φ15.9) × 0.170

Warning

The total refrigerant charge of the system, including factory charge and additional charge, must not exceed the maximum design refrigerant charge of 14 kg.

Determine the total refrigerant charge amount of the system:
Total charge (Mc) = factory charge + additional charge = R0 + R.
The factory charge (R0) can be obtained from Table 9-1.

6. ELECTRICAL WIRING

6.1 Safety Device Requirements

1. Select the wire diameters (minimum value) individually for each unit based on the rated current, as shown in Table 6-1 and Table 6-2.
2. For thee-phase units, the maximum allowable voltage range variation between phases is 2%.
3. Select a circuit breaker that has a contact separation in all poles not less than 3 mm providing full disconnection, where MFA is used to select the current circuit breakers and residual current operation breakers.
4. The current carrying capacity of the conductor wire is only for users’ reference. The actual current carrying capacity has different correction coefficients depending on the cable type and length, the pipe penetration method, and the actual laying environment. Users are recommended to make corrections according to local regulations and specific installation circumstances.

• Do not share the same power supply line with other devices.

• The power cord may produce electromagnetic interference so you should maintain a certain distance from equipment that may be susceptible to such interference.

• Separate power supply for the indoor and outdoor units.

Warning

• Take note of the risk of electric shocks during installation.
• All the electric wires and components must be installed by a certified electrician, and the installation process must comply with applicable regulations.
• Use only wires with copper cores for the connections.
• A main breaker or safety device that can disconnect all polarities must be installed, and the breaker device can be completely disconnected in situations where there is excessive voltage
• Wiring must be carried out in strict accordance with what is stated on the product nameplate.
• Do not squeeze or pull the unit connection, and make sure the wiring is not in contact with the sharp edges of the sheet metal.
• Make sure the grounding connection is safe and reliable. Do not connect the earth wire to public pipes, telephone earth wires, surge absorbers and other places that are not designed for grounding. Improper grounding may cause electric shock.
• Make sure the fuses and circuit breakers installed meet the corresponding specifications.
• Make sure an electric leakage protection device is installed to prevent electric shocks or fires.
• The model specifications and characteristics (anti high-frequency noise characteristics) of the electric leakage protection device should be compatible with the unit to prevent frequent tripping.
• Before powering the unit on, make sure the connections between the power cord and terminals of the components are secure, and the metallic cover of the electric control box is closed tightly.

6.2 Connecting the Power Cord

NOTE

• Do not connect the power supply to the communication terminal block. Otherwise, the whole system may fail.
• You must first connect the earth line (note that you should use only the yellow-green wire to connect to the earth, and you must turn off the power supply when you are connecting the earth line) before you connect the power cord. Before you install the screws, you must first comb through the path along the wiring to prevent any part of the wiring from becoming exceptionally loose or tight because of inconsistencies in the lengths of the power cord and earth line.
• The wire diameter must comply with the specifications, and the terminal should be screwed tightly. Do not subject the terminal to any external force.
• Seal the wiring connection with insulation material, or condensation may occur.
• Use round-type terminals of the correct specifications to connect the power cable

Warning

When inserting the strong-current cables and communication lines into the wiring holes, they must be equipped with wiring across rings to avoid being worn.

6.3 Connecting the Communication Wiring

NOTE

For a single-phase system, the EMI effect of the communication line M1M2 (or PQE) can be improved by adding a magnetic ring. The installation is shown in the figure below. The magnetic ring needs to be fixed with the communication line (it can be wound for one or more turns), and placed in the machine to prevent it from falling off.

▪ Wiring layout is comprised of the communication wiring between the indoor and outdoor units. These include the earth lines, and the shielded layer of the earth lines of the indoor units in the communication line. See below the wiring layout of outdoor unit.

Warning

• Do not connect the communication line when the power is on.
• Connect the shielding nets at both ends of the shielded wire to the sheet metal “ ” of the electronic control box.
• Do not connect the power cable to the terminal of communication line, otherwise, the motherboard will be damaged.
• Do not connect a system with both EasyCom (M1 M2) communication lines and PQ communication lines.

CAUTION

• On-site wiring must comply with the relevant regulations of the local country/region and must be completed by professionals.
• The communication lines of the IDUs and ODU can only be led out and connected from the ODU.
• When a single communication line is not long enough, the joint must be crimped or soldered, and the copper wire at the joint shall not be exposed.
• Applicable standards: EN 55014-1 and EN 55014-2. The communication line must be shielded wire.

Before connecting the communication wiring, please select the appropriate connection method. Refer to the following table:

• EasyCom (M1 M2) communication wiring configuration – All IDUs in a system must be powered through a power supply

Caution

• Keep the power on/off for all IDUs.
• Do not connect the EasyCom (M1 M2) communication line to the PQ or D1D2 communication line.
• Arbitrary topology wiring.
• Applicable standards: EN 55014-1 and EN 55014-2. The communication line must be shielded wire.
• After the final indoor unit, the communication wiring CAN be continued back to the outdoor unit to ensure communication in case of disconnection point. In this situation M1 M2 are polarized and M1 should connect to M1, M2 should connect to M2. If wrongly connected the PCB may be damaged.
• EasyCom (M1 M2) communication wiring configuration – IDUs with separate power supply

Caution

• If the total distance is less than or equal to 200m and the total number of IDUs is less than or equal to 10 sets, the valve is powered and controlled by the ODU.

• If the total distance is longer than 200m or the total number of IDUs is more than 10 sets, a repeater is required to increase the bus voltage.

• The load capacity of the repeater is the same as that of the ODU, and it can load a bus length of 200m or 10 IDUs.

• A maximum of one repeater can be installed in the same refrigerant system.

• The number of IDUs requiring power supply in the same refrigerant system is less than or equal to 11 sets.

• Keep the power on/off for both the repeater and the ODU, or use an uninterruptible power supply with the repeater.

• For repeater installation, please refer to the repeater installation manual. Do not connect the upstream and
  downstream IDU ports of the repeater in reverse; otherwise, it will cause a communication failure.

• Arbitrary topology wiring.

• Applicable standards: EN 55014-1 and EN 55014-2. The communication line must be shielded wire.

• After the final indoor unit, the communication wiring CAN be continued back to the outdoor unit to ensure communication in case of disconnection point. Max number of IDUs connected is 10. In this situation M1 M2 are polarized and M1 should connect to M1, M2 should connect to M2. If wrongly connected the PCB may be damaged.

Caution

• After the last indoor unit, the communication wiring should not route back to the outdoor unit as this will form a closed loop.
• In the last indoor unit, connect a resistor of 120 ohms between the P and Q terminals.
• Do not bind the communication line, refrigerant piping and power cable together.
• When the power cable and communication line are laid in parallel, the distance between the two lines must be 5cm or more to prevent signal source interference.
• All IDUs in a system must be powered through a power supply so that they can be powered on or off at the same time.
• All communication lines of the IDUs and ODU must be connected in a series, use the shielded wire, and the shield layer must be grounded.
• Applicable standards: EN 55014-1 and EN 55014-2. The communication line must be shielded wire.

Caution

• The cross-sectional area of each core of the communication wiring is not less than 0.75 mm2, and the length must not exceed 1200 m.

8. COMMISSIONING

8.1 Overview

After installation, and once the field settings have been defined, the installation personnel must verify the correctness of the operations. Follow the steps below to perform the test run.

This chapter describes how the test run can be carried out once the installation is complete, and other relevant information.

The test run usually includes the following stages:

1. Review the “Checklist Before Test Run”.
2. Implement the test run.
3. If necessary, correct the errors before the test run completes with exceptions.
4. Run the system

8.2 Things to Note During the Test Run

Warning

• During the test run, the outdoor unit operates at the same time with the indoor units connected to it. It is very dangerous to debug the indoor units during the test run.
• Do not insert your fingers, sticks, or other items into the air inlet or outlet. Do not remove the fan mesh cover. When the fan rotation is set at a high speed, it may cause bodily injury.

NOTE

Note that the required input power may be higher when this unit is run for the first time. This phenomenon is due to the compressor which needs to run for 50 hours before it can achieve a stable operating and power consumption state. Make sure the power supply is turned on 12 hours before operations so that the crankcase heater is properly energized. This is also to protect the compressor.

INFORMATION

The test run can be carried out when the ambient temperature is within the required range as in Figure 8-1.

During the test run, the outdoor unit and indoor units will start at the same time. Make sure all the preparations for the outdoor unit and indoor units have been completed.

8.3 Checklist Before Test Run

Once this unit is installed, check the following items first. After all the following checks have been completed, you must shut down the unit. This is the only way to start the unit again.

8.4 About Test Run

The following procedures describe the test run of the whole system. This operation checks and determines the following items:

• Check if there is a wiring error (with the communication check of the indoor unit).
• Check if the stop valve is open.
• Determine the length of the pipe.

INFORMATION

• Before you start the compressor, it may take 10 minutes to achieve a uniform cooling state.
• During the test run, the sound of the cooling mode in operation or the solenoid valve may become louder, and there may be changes in the displayed indicators. This is not a malfunction.

8.5 Test Run Implementation

1. Make sure all the settings you need to configure are completed. See section 7.2 on the implementation of the field settings.
2. Turn on the power supply of the outdoor unit and the indoor units.

INFORMATION

Make sure the power supply is turned on 12 hours before operations so that the crankcase heater is properly energized. This is also to protect the compressor.

Specific procedures for the test run are as follows:
Step 1: Power on

The 4th digit of the digital display represents the communication protocol type, the initial value is 0. Short press the “DOWN” or “UP” button to change the communication protocol.

If the system is all V8 IDUs, and the IDUs and ODU are connected by PQ communication, please select V8 protocol RS-485 (P Q) communication, and set the 4th digit of the ODU digital display to 0; ODU factory default V8 protocol RS-485 (P Q) communication.

If the system has a non-V8 IDUs, and the IDUs and ODU are connected by PQE communication, please select the non-V8 protocol RS-485 (P Q E) communication and set the 4th digit of the ODU digital display to 1.

If the system is all V8 IDUs, the IDUs and ODU are connected by M1M2 communication, and all IDUs are powered uniformly, please select the EasyCom (M1M2) communication + indoor unit uniform power supply, and set the 4th digit of the ODU digital display to 2.

If the system is all V8 IDUs, the IDUS and ODU are connected by M1M2 communication, and there is separate power supply for IDUS, please select the EasyCom (M1M2) communication + indoor unit separate power supply, and set the 4th digit of the ODU digital display to 3.

Once the communication protocol has been set, short press the “OK” button to confirm and automatically proceed to the next step.

Step 5: IDUs and ODU address setting
Enter the auto addressing function, the digital display of ODU flashes “AU Ad” and “X YZ” in rotation. “AU Ad” means the auto addressing is in progress, “X” represents the address of the ODU, “YZ” represents the number of detected IDUs; the auto addressing takes about 5-7 minutes, and automatically proceed to the next step after completion.

Step 6: System initialization
Entering system initialization, the digital display of ODU flashes “AU Ad” and “X YZ” in rotation. “INIt” means initialization is in progress, “X” represents the address of the ODU, “YZ” represents the number of detected IDUs; the system initialization takes about 3-5 minutes, and automatically proceed to the next step after completion.

Step 7: End
After system initialization, if there is no fault in the system, ODU will enter standby mode and the digital display will display “X YZ” (“X” represents the address of the ODU, “YZ” represents the number of detected IDUs), and the unit can be turned on normally.

After system initialization, if the ODU detects a fault, the digital display of ODU will display “X YZ” (“X” represents the address of the ODU, “YZ” represents the number of detected IDUs) and the error code in rotation. Please refer to the Error Code Table for troubleshooting, and the unit can be turned on normally after the fault is cleared.

9. PRECAUTIONS ON REFRIGERANT LEAKAGE

This air conditioner (A/C) adopts inncouous and nonflammable refrigerant. The locating room of the A/C should big engough that any refrigerant leakage is unable to reach critical thickness. So certain esssential action can be taken on time.

Critical thickness——the Max. thickness of Freon without any harm to person.

Refrigerant critical thickness: 0.44[kg/m ] for R410A.
Confirm the critical thickness through follow steps, and take necessary actions.

If leak is suspected, keep the area ventilated to avoid the risk of refrigerant stagnating, and remove/extinguish all naked flames.

1. Calculate the sum of the charge amount (A[kg])
   Total Refrigerant amount = factory refrigerant amount + additional refrigerant charge amount.

2. Calculate the indoor cubage (B[m ]) (as the minimum cubage.

3. Calculate the refrigerant thickness
