• Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise it may cause imperfect combustion.

Installation

• When the indoor unit is to be suspended, the designated hanging bolts (M10 or W3/8) and nuts (M10 or W3/8) must be used.
• Install the air conditioner securely in a location where the base can sustain the weight adequately. If the strength is not enough, the unit may fall down resulting in injury.
• Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow these instructions may cause the product to fall down or topple over or give rise to noise, vibration, water leakage or other trouble.
• Carry out the specified installation work to guard against the possibility of high winds and earthquake. If the air conditioner is not installed appropriately, a unit may topple over or fall down, causing an accident.
• If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• Use forklift to carry in the air conditioner units and use winch or hoist at installation of them.

Refrigerant piping

• Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the compressor is operated with the valve open and without refrigerant pipe, the compressor sucks air and the refrigeration cycles is over pressurized, which may cause an injury.
• Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may result in refrigerant leakage.
• After the installation work, confirm that refrigerant gas does not leak. If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas may be generated.
• When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air completely may cause the air conditioner to malfunction.
• Nitrogen gas must be used for the airtight test.
• The charge hose must be connected in such a way that it is not slack.

Electrical wiring

• Only a qualified installer(1) or qualified service person(1) is allowed to carry out the electrical work of the air conditioner.
  Under no circumstances must this work be done by an unqualified individual since failure to carry out the work properly may result in electric shocks and/or electrical leaks.

• To connect the electrical wires, repair the electrical parts or undertake other electrical jobs, wear gloves to provide protection for electricians and from heat, insulating shoes and clothing to provide protection from electric shocks.
  Failure to wear this protective gear may result in electric shocks.

• Use wiring that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws.
  Use of wiring which does not meet the specifications may give rise to electric shocks, electrical leakage, smoking and/or a fire.

• Connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.

• Do not connect earth wires to gas pipes, water pipes, and lightning conductor or telephone earth wires.

• After completing the repair or relocation work, check that the earth wires are connected properly.

• Install a circuit breaker that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws.

• Install the circuit breaker where it can be easily accessed by the agent.

• When installing the circuit breaker outdoors, install one which is designed to be used outdoors.

• Under no circumstances the power wire must not be extended.
  Connection trouble in the places where the wire is extended may give rise to smoking and/or a fire.

• Electrical wiring work shall be conducted according to law and regulation in the community and Installation Manual.
  Failure to do so may result in electrocution or short circuit.

Test run

• Before operating the air conditioner after having completed the work, check that the electrical control box cover of the indoor unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may receive an electric shock if the power is turned on without first conducting these checks.

• If there is any kind of trouble (such as an error display has appeared, smell of burning, abnormal sounds, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner, do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service person. Take steps to ensure that the power will not be turned on (by marking “out of service” near the circuit breaker, for instance) until qualified service person arrives.
  Continuing to use the air conditioner in the trouble status may cause mechanical problems to escalate or result in electric shocks or other trouble.

• After the work has finished, use an insulation tester set (500V Megger) to check the resistance is 1MΩ or more between the charge section and the non-charge metal section (Earth section). If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.

• Upon completion of the installation work, check for refrigerant leaks and check the insulation resistance and water drainage.
  Then conduct a test run to check that the air conditioner is operating properly.

Explanations given to user

• Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does not know where the circuit breaker is, he or she will not be able to turn it off in the event that trouble has occurred in the air conditioner.
• If the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF position, and contact a qualified service person to have the repairs done. Do not set the circuit breaker to the ON position until the repairs are completed.
• After the installation work, follow the Operations Manual to explain to the customer how to use and maintain the unit.

Relocation

• Only a qualified installer(1) or qualified service person(1) is allowed to relocate the air conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric shocks, injury, water leakage, noise and/or vibration
  may result.

• When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe.
  Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will cause air or other gas to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupture, injury or other trouble.

CAUTION

• The hard vinyl-chloride pipe cannot be directly connected to the drain pipe connecting port of the indoor unit.
  For connection with the drain pipe connecting port, be sure to use / fix the attached flexible hose with the hose band, otherwise a damage or water leak is caused on the drain pipe connecting port.

Adhesive inhibited :
Use the attached flexible hose and hose band for connecting the drain hose to the clear drain socket.
If applying the adhesive, socket will be damaged and cause water leakage.

Connecting drain pipe

• Connect a hard socket (locally procured) to the hard socket of the attached supplied flexible hose.
• Connect a drain pipe (locally procured) to the connected hard socket.

REQUIREMENT

• Connect hard vinyl chloride pipes securely using an adhesive for vinyl chloride to avoid water leakage.
• It takes some time until the adhesive is dried and hardened (refer to the manual of the adhesive).
  Do not apply stress to the joint with the drain pipe during this time period.

Drain up
When a down-gradient cannot be secured for the drain pipe, drain-up piping is possible.

• The height of the drain pipe must be 500 mm or less rom the bottom of the ceiling.
• Take the drain pipe out of the drain pipe joint with the indoor unit in 300 mm or less, and bend up the pipe vertically.
• Immediately after the pipe is bent up vertically, lay the pipe making a down-gradient.
• Set downward grading immediately after raising up vertically.

Check the draining
In the test run, check that water drain is properly performed and water does not leak from the connecting part of the pipes.
Be sure to check draining also when installed in heating period.
Using a pitcher or hose, pour water (1500 to 2000 cc) into the suction port before installation of the ceiling panel.
Pour water gradually so that water does not spread on the motor of the drain pump.

CAUTION
Pour water gently so that it does not spread around inside the indoor unit, which may cause a malfunction.

• After the electric work has finished, pour water during COOL mode operation.

• If the electric work has not yet finished, pull out the float switch connector (CN34: Red) from the electrical control box, and check draining by plugging the single phase 208 to 240V power to the terminal blocks (L) and (N).
  If doing so, the drain pump motor operates.
  (Never apply 208 to 240V to (Uv (U1)), (Uv (U2)), (A), (B) otherwise a trouble of P.C. Board occurs.)

• Test water drain while checking the operation sound of the drain pump motor.
  (If the operation sound changes from continuous sound to intermittent sound, water is normally drained.)
  After the check, the drain pump motor runs, connecting the float switch connector.
  (In case of check by pulling out the float switch connector, be sure to return the connector to the original position.)

Heat insulating

Permissible piping length and height difference
They vary depending on the outdoor unit. For details, refer to the Installation Manual attached to the outdoor unit.

CAUTION
IMPORTANT 4 POINTS FOR PIPING WORK

1. Reusable mechanical connectors and flared joints are not allowed indoors. When mechanical connectors are reused indoors, sealing parts shall be renewed. When flared joints are reused indoors, the flare part shall be refabricated.
2.  Tight connection (between pipes and unit)
3. Evacuate the air in the connecting pipes by using VACUUM PUMP.
4. Check the gas leakage. (Connected points)

Pipe size

Model name

| UP0151, UP0181 type| UP0241, UP0271 type
---|---|---
Pipe size| Gas side| 12.7 mm| 15.9 mm
Liquid side| 6.4 mm| 9.5 mm

**** Connecting refrigerant piping

Flaring

• Cut the pipe with a pipe cutter.
  Remove burrs completely.
  Remaining burrs may cause gas leakage.

• Insert a flare nut into the pipe, and flare the pipe.
  As the flaring sizes of R32 or R410A differ from those of refrigerant R22, the flare tools newly manufactured for R32 or R410A are recommended.
  However, the conventional tools can be used by adjusting projection margin of the copper pipe.

Projection margin in flaring: B (Unit: mm)

Flaring diameter size: A (Unit: mm)

**CAUTION**

• Do not scratch the inner surface of the flared part when removing burrs.
• Flare processing under the condition of scratches on the inner surface of flare processing part will cause refrigerant gas leak.
• Check that the flared part is not scratched, deformed, stepped, or flattened, and that there are no chips adhered or other problems, after flare processing.
• Do not apply refrigerating machine oil to the flare surface.
• In case of flaring for R32 or R410A with the conventional flare tool, pull it out approx. 0.5 mm more than that for R22 to adjust to the specified flare size. The copper pipe gauge is useful for adjusting projection margin size.
  • The sealed gas was sealed at the atmospheric pressure so when the flare nut is removed, there will no “whooshing” sound: This is normal and is not indicative of trouble.
  • Use two wrenches to connect the indoor unit pipe.
  • Use the tightening torque levels as listed in the following table.

Tightening torque of flare pipe connections
Incorrect connections may cause not only a gas leak, but also a trouble of the refrigeration cycle.
Align the centres of the connecting pipes and tighten the flare nut as far as possible with your fingers. Then tighten the nut with a spanner and torque wrench as shown in the figure.

CAUTION
Tightening with an excessive torque may crack the nut depending on installation conditions.

Evacuation
Perform vacuuming from the charge port of valve of the outdoor unit by using a vacuum pump.
For details, follow to the Installation Manual attached to the outdoor unit.

• Do not use the refrigerant sealed in the outdoor unit for evacuation.

REQUIREMENT
For the tools such as charge hose, use those manufactured exclusively for R32 or R410A.

Refrigerant amount to be added
For addition of the refrigerant, add refrigerant “R32 or R410A” referring to the attached Installation Manual of outdoor unit.
Use a scale to charge the refrigerant of specified amount.

REQUIREMENT

• Charging an excessive or too little amount of refrigerant causes a trouble of the compressor.
  Charge the refrigerant of specified amount.

• A personnel who charged the refrigerant should write down the pipe length and the added refrigerant amount in the F-GAS label of the outdoor unit. It is necessary to fix the compressor and refrigeration cycle malfunction.

Open the valve fully
Open the valve of the outdoor unit fully.
A 4 mm-hexagonal wrench is required for opening the valve.
For details, refer to the Installation Manual attached to the outdoor unit.

Gas leak check
Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section or cap of the valve.

REQUIREMENT
Use a leak detector manufactured exclusively for HFC refrigerant (R32, R134a, R410A, etc).

Airtight test / Air purge, etc.
For airtight test, air purge, addition of refrigerant, and gas leak check, refer to the Installation Manual attached to the outdoor unit.

REQUIREMENT
Do not supply power to the indoor unit until the airtight test and vacuuming are completed.
(If the indoor unit is powered on, the pulse motor valve is fully closed, which extends the time for vacuuming.)

Heat insulation process
Apply heat insulation for the pipes separately at liquid side and gas side.
For the heat insulation to the pipes at gas side, be sure to use the material with heat-resisting temperature 120°C or higher.
Using the attached heat insulation material, apply the heat insulation to the pipe connecting section of the indoor unit securely without gap.

REQUIREMENT

• Apply the heat insulation to the pipe connecting section of the indoor unit securely up to the root without exposure of the pipe. (The pipe exposed to the outside causes water leak.)
•  Wrap heat insulator with its slits facing up (ceiling side).

Electrical connection

WARNING

• Use the specified wires for wiring connection to the terminals. Securely fix them to prevent external forces applied to the terminals from affecting the terminals.
  Incomplete connection or fixation may cause a fire or other trouble.

•  Connect earth wire. (grounding work) Incomplete earthing cause an electric shock.
  Do not connect earth wires to gas pipes, water pipes, lightning conductor or telephone earth wires.

• Appliance shall be installed in accordance with national wiring regulations.
  Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.

CAUTION

• The wire size and wire length of the communication line differs depending on the outdoor unit series to be connected.

• If incorrect / incomplete wiring is carried out, it will cause an electrical fire or smoke.

• Install an earth leakage breaker that is not tripped by shock waves.
  If an earth leakage breaker is not installed, an electric shock may be caused.

• Use the cord clamps attached to the product.

• Do not damage or scratch the conductive core and inner insulator of power and control wires when peeling them.

• Use the power supply wire and control wires of specified thickness, type, and protective devices required.

• Do not connect 208 to 240V power to the terminal blocks (Uv (U1)), (Uv (U2)), (A), (B) for control wiring.
  (Otherwise, the system will fail.)

• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
  The coating may melt resulting in an accident.

• Be careful of fan operation when the circuit breaker is turned on. When the leak detector is connected in combination with the R32 outdoor unit, if the refrigerant leak detection sensor detects the refrigerant leak, a fan automatically rotates even while an air conditioner stops. Be careful not to be injured by the fan.

Warnings on Refrigerant Leakage

Check of Concentration Limit
The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.

Refrigerant R32
The refrigerant R32 which is used in the air conditioner is mildly flammable. In Europe and areas where IEC standards apply, EN/IEC 60335-2-40 is the applicable standard. The refrigerant R32 does not have the toxicity of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. If this appliance is connected with the outdoor unit containing R32 refrigerant, refer to the Installation and Owner’s Manual attached to the outdoor unit.

Refrigerant R410A
The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of space, individual control, energy conservation by curtailing heat and carrying power etc.
Most importantly, the multi air conditioner system is able to hold a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).
In a room where the concentration may exceed the limit imposed by the local regulation, create an opening with adjacent rooms, or install mechanical ventilation or isolation, combined with a gas leak detection device, which complies with the local regulatory requirements.
The concentration calculation method is as given below. Please note the concentration limit between R32 and R410A refrigerant differs. Refrigerant Concentration Limit shall be in accordance with local regulations.
▼ NOTE 1
If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

For the amount of charge in this example:
The possible amount of leaked refrigerant gas in rooms A, B and C is 10 kg.
The possible amount of leaked refrigerant gas in rooms D, E and F is 15 kg.

▼ NOTE 2
The standards for minimum room volume are as follows.

1. No partition (shaded portion) IMPORTENT
2. When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).
3. If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.

▼ NOTE 3
System compliance has been completed to IEC60335-2-40 Ed6. If EN378 compliance is required please refer separately to EN378 for guidance.

Appendix

Work instructions
The existing R22 and R410A piping can be reused for inverter R32 product installations.

WARNING
Confirming the existence of scratches or dents on the existing pipes and confirming the reliability of the pipe strength are conventionally referred to the local site.
If the specified conditions can be cleared, it is possible to update existing R22 and R410A pipes to those for R32 models.

Basic conditions needed to reuse existing pipes
Check and observe the presence of three conditions in the refrigerant piping works.

1. Dry (There is no moisture inside of the pipes.)
2. Clean (There is no dust inside of the pipes.)
3. Tight (There are no refrigerant leaks.)

Restrictions for use of existing pipes
In the following cases, the existing pipes should not be reused as they are. Clean the existing pipes or exchange them with new pipes.

1. When a scratch or dent is heavy, be sure to use new pipes for the refrigerant piping works.

2.  When the existing pipe thickness is thinner than the specified “Pipe diameter and thickness,” be sure to use new pipes for the refrigerant piping works.
   • The operating pressure of refrigerant is high. If there is a scratch or dent on the pipe or a thinner pipe is used, the pressure strength may be inadequate, which may cause the pipe to break in the worst case.
   * Pipe diameter and thickness (mm)**** Pipe outer diameter| Ø6.4Ø| 9.5| Ø12.7| Ø15.9
   ---|---|---|---|---
   Thickness| R32, R410A| 0.8| 0.8| 0.8| 1.0
   R22

3. When the outdoor unit was left with the pipes disconnected, or the gas leaked from the pipes and the pipes were not repaired and refilled.
   •  There is the possibility of rain water or air, including moisture, entering the pipe.

4. When refrigerant cannot be recovered using a refrigerant recovery unit.
   •  There is the possibility that a large quantity of dirty oil or moisture remains inside the pipes.

5. When a commercially available dryer is attached to the existing pipes.
   • There is the possibility that copper green rust hasbeen generated.

6. When the existing air conditioner is removed after refrigerant has been recovered.
   Check if the oil is judged to be clearly different from normal oil.
   • The refrigerator oil is copper rust green in color: There is the possibility that moisture has mixed with the oil and rust has been generated inside the pipe.
