4.4 Piping Installation

• Refer to the installation manual attached with the outdoor unit on installation of the refrigerant piping for the outdoor unit.

• All gas and liquid piping must be properly insulated; otherwise, this may cause water to leak. Use heat insulation materials that can withstand high temperatures above 120°C to insulate the gas pipes. In addition, the insulation of the refrigerant piping should be reinforced (20 mm or thicker) in situations where there is high temperature and/or high humidity (when part of refrigerant piping part is higher than 30°C or when the humidity exceeds RH80%). Otherwise, the surface of the heat insulation material may be exposed.

• Before the works are carried out, verify that the refrigerant is R410A. If the wrong refrigerant is used, the unit may malfunction.

• Other than the specified refrigerant, do not let air or other gases enter the refrigeration circuit.

• If the refrigerant leaks during installation, make sure you fully ventilate the room.

• Use two wrenches when you install or dismantle the piping, a common wrench and a torque wrench. See Figure 4.1.

• Slot the refrigerant piping into the brass nut (accessory 8), and expand the pipe socket. Refer to the following table for the size of the pipe socket and the appropriate tightening torque.

⚠ Caution

• Apply the appropriate tightening torque according to the installation conditions. Excessive torque will damage the socket cap, and the cap will not be tight if you apply insufficient torque, leading to leakages.
  Do not let air, dust, and other particles invade the piping system during the installation of the connecting pipes. Install the connecting pips only when the indoor and outdoor units are secured. Make sure to keep the connecting pipes dry during installation so that no water will enter the piping system.

• Before the socket cap is installed on the pipe socket, apply some refrigerant oil on the socket (both inside and outside), then rotate it three or four times before you tighten the cap. See Figure 4.2.

⚠ Precautions to take when welding the refrigerant pipes

• Before you weld the refrigerant pipes, fill the pipes with nitrogen first to discharge the air in the pipes. If no nitrogen is filled during welding, a large amount of oxide film will form inside the piping which may cause the air conditioning system to malfunction.
• Welding can be carried out on the refrigerant pipes when the nitrogen gas has been replaced or refilled.
• When the pipe is filled with nitrogen during welding, the nitrogen must be reduced to 0.02 MPa using the pressure release valve. See Figure 4.3.

11. Air Conditioner Operations and Performance

The operating temperature range under which the unit runs stably are given in below table.

To ensure the desired temperature is achieved efficiently, ensure that: All windows and doors are closed. The airflow direction is adjusted to work in running mode.
The air filter is clean.
Please note how you can best save energy and achieve the best cooling/heating effect. Regularly clean air filters inside indoor units.

Maintain a proper air distribution. Air outlet louvers should be
used to adjust the direction of outlet airflow, as doing so might
ensure more efficient operation.

12. Adjusting Air Flow Direction

Since warmer air rises and cooler air falls, the distribution of warmed/cooled air around a room can be improved by positioning the unit’s louvers. The louver angle can be adjusted by pressing the [SWING] button on the remote controller.

Caution

• During heating operation, horizontal airflow will aggravate the uneven distribution of room temperature.
• The louver direction: horizontal airflow is recommended during cooling operation. Note the downward airflow will cause condensation on the air outlet and louver surface.

13. Maintenance

Caution

• Please release pressure before disassembly.

• Before you clean the air conditioner, ensure it is powered off.

• Check that the wiring is undamaged and connected.

• Use a dry cloth to wipe the indoor unit and remote controller.

• A wet cloth may be used to clean the indoor unit if it is very
  dirty.

• Never use a damp cloth on the remote controller.

• Do not use a chemically treated duster on the unit or leave this type of material on the unit to avoid damaging the finish.

• Do not use benzene, thinner, polishing powder, or similar
  solvents for cleaning. These may cause the plastic surface to crack or warp.

Method for cleaning the air filter
a. The air filter can prevent the dust or other particles from entering the unit. If the filter is blocked, the unit will not work well. Clean the filter every two weeks when you use it regularly.
b. If the air conditioner is positioned in a dusty place, clean the filter often.
c. Replace the filter if it is too dusty to clean (the replaceable air filter is an optional fitting).

1. Open the unit Open the unit by placing your fingers under the notches on the sides of the cover and moving the cover outwards. Open the cover fully to allow sufficient room to remove the filter.

2. Dismantle the filter
   Gently push the filter upwards to release the notches, then pull the filter out.

3. Clean the air filter Dusts will accumulate on the filter along with the unit operation, and need to be removed from the filter, or the unit would not function effectively. Clean the filter every two weeks when you use the unit regularly. Clean the air filter with a vacuum cleaner or water. a. The air intake side should face up when using a vacuum
   cleaner. (Refer to Figure 13.3) b. The air intake side should face down when using clean water.
   (Refer to Figure 13.4) For excessive dusts, use a soft brush and natural detergent to clean it and dry in a cool place.
   Caution
   · Do not dry out the air filter under direct sunshine or with fire.
   · The air filter should be installed before the unit body installation.

4. Re-install the air filter.

5. Install and close the air inlet grille by reversing steps 1 and 2. Maintenance before stopping using the unit for a long time (e.g., at the end of a season)
   a. Let the indoor units run in fan only mode for about half a day to dry the interior of the unit.
   b. Clean the air filter and indoor unit casing.
   c. Refer to “Cleaning the air filter” for details. Install cleaned air filters back in their original positions.
   d. Turn off the unit with the ON/OFF button on the remote controller, and then unplug it.

Caution

• When the power switch is connected, some energy will be
  consumed even if the unit is not running. Disconnect the power to save energy.

• A degree of dirt will accumulate when the unit has been used several times, which will require cleaning.

• Take of the batteries from the remote controller.

Maintenance after a long period of non-use
a. Check for and remove anything that might be blocking the inlet and outlet vents of the indoor units and outdoor units.
b. Clean the unit casing and clean the filter. Refer to [Cleaning the filter] and “Cleaning the filter” for instructions. Re-install the filter before running the unit.
c. Turn on the power at least 12 hours before you want to use the unit to ensure it works properly. As soon as the power is turned on, the remote control display appears.

14. Symptoms That Are Not Faults

The following symptoms may be experienced during the normal operation of the unit and are not considered faults. Note: If you are not sure whether a fault has occurred, contact your supplier or service engineer immediately.

Symptom 1: The unit will not run Symptom: When the ON/OFF button on the remote controller is
pressed, the unit does not immediately start running. Cause: to protect certain system components, system start-up or re-start is intentionally delayed for up to 12 minutes under some operating conditions. If the OPERATION LED on the unit’s panel is lighting, the system is working normally and the unit will start after the intentional delay is complete.
Heating mode is running when the following panel lights are on:operation and the DEF./FAN LED indicator. Cause: the indoor unit activates protective measures because of the low outlet temperature.

Symptom 2: The unit emits white mist White mist is generated and emitted when the unit starts to
operate in a very humid environment. This phenomenon will stop once the humidity in the room is reduced to normal levels. The unit occasionally emits white mist when it runs in heating mode. This occurs when the system finishes periodic defrosting. Moisture that may accumulate on the unit’s heat exchanger coil during defrosting becomes mist and is emitted from the unit.

Symptom 3: Dust is emitted from the unit This can occur when the unit first runs after a long idle period.

Symptom 4: The unit gives off a strange odor If smells such as those of strong-smelling food or tobacco smoke
are present in the room, they can enter the unit, leave trace deposits on the unit’s internal components, and later be emitted from the unit.

INFORMATIVE TIP
The outdoor units Mini VRF // M5 // MV6 // MW (water source) series, dispose of the possibility to address MANUALLY or AUTOMATICALLY the indoor units.
The outdoor units MHR series (3 pipes heat recovery system) only dispose of the possibility to address MANUALLY the indoor units.

HOW to carry out the MANUAL addressing and WHEN use it:
Always, on the system with outdoor unit MHR series (3 pipes heat recovery system);
The manual addressing allows the user to set a specific address (from 0 to 63) to the main PCB of an indoor unit.
If the wired-controller or the wireless controller dispose of “addressing” function, it’s necessary to carry out the procedure written on the controller manual :each controller has its procedure.
[1] It’s advisable, but NOT strictly necessary, to carry out the addressing with a consecutive numbering (starting from 0).
[2] If there are more VRF systems to connect at a single centralized, it’s MANDATORY that all the indoor units have their addresses different from each other (indoor units with the same address are NOT permitted);
WARNING:
If the VRF system is connected to a centralized controller (ex: CCM09 // CCM30 // CCM15) it’s MANDATORY setting the address-dip-switch on the outdoor unit in AUTOMATIC position.
Power-off and power-on the system.
This will NOT modify the set addressee of the indoor units (neither powering off/on the system): it’s only a modify of the dip-switch position.

HOW to carry out the AUTOMATIC addressing and WHEN use it:
With the automatic addressing the outdoor unit assigns arbitrarily an address (always a progressive number from 0 to n-1) at each of the n indoor units main PCBs;
The automatic addressing CAN be modified subsequently MANUALLY always leaving the addressing dip-switch of the outdoor unit in AUTOMATIC position.
Real case (example):
– a system equipped with 23 indoor units is addressed automatically;
– the set adresses start from 0 to 22;
– the user want to set a set the address 63 to a specific indoor unit (in order to use the VIP function);
– it is possible to carry out the manual addressing (as explained in the previus topic) WITHOUT modify the addressing dip-switch of the outdoor unit (leave it in AUTOMATIC).
– Power-off and power-on the system.
We advise to use this type of addressing on a single VRF system.

ELECTRICAL WIRING
The type of cable used for RS 485 communication, if not suitable for such use, can compromise the packets transmission. For the specific case, it requires a 3-wire+ shield cable for the RS 485 type transmission. Attention: the type of cable used must be checked for “type of data transmitted” according to the installation where it will be placed too. Following some key-point that must be respect in order to get the best communication performance: Shield connection:
· The serial cable shield must be connect to a noise-free ground. · The shield must be connect to the ground at one point only. · The continuity of the screen must be provide throughout the extension of the serial cable. NB: These provisions are generally valid. In some areas characterized by the presence of particular types of coupling of electromagnetic disturbances, a different type of screen connection may be necessary.

General prescriptions:

• The cable must have insulation and voltage characteristics in accordance with current electrical standards.
• The insulation of the cable must have characteristics of no propagation of the flame or fire, commensurate with the reference electrical standards for the type of system on which it is place.
• The cable must be place according to the rules of the art rule.
• The cable must be place separately with respect to other cables, especially if they are power cables or powered at different voltages
• The cable must be place away from cables or devices that can induce electromagnetic noise.
• The RS485 serial line must be make in “Bus topology ­ hand by hand”. Different topologies are not allowed (ring, star etc.)
• The serial line must be place by trained and experienced electricians in data communication networks.
