6 Installation Details

6.1 Wrench torque sheet for nstallation

6.2 Connecting the cables

The power cord should be selected according to the following specifications sheet.

The cable size and the current of the fuse or switch is determined by the maximum current indicated on the nameplate which located on the side panel of the unit. Please refer to the nameplate before selecting the cable, fuse and switch.

6.4 Installation for the first time

Air and moisture in the refrigerant system have undesirable effects as below:

● Pressure in the system rises.

● Operating current rises.

● Cooling or heating efficiency drops.

● Moisture in the refrigerant circuit may

freeze and block capillary tubing.

● Water may lead to corrosion of parts in the refrigerant system.

Therefore, the indoor units and the pipes between indoor and outdoor units must be leak tested and evacuated to remove gas and moisture from the system.

Gas leak check (Soap water method):

Apply soap water or a liquid neutral detergent on the indoor unit connections or outdoor unit connections by a soft brush to check for leakage of the connecting points of the piping. If bubbles come out, the pipes have leakage.

6.3 Pipe length and the elevation

1. Air purging with vacuum pump

1) Completely tighten the flare nuts of the

indoor and outdoor units, confirm that both the 2-way and 3-way valves are set to the closed position.

2) Connect the charge hose with the push pin

of handle lo to the 3-way valves gas service port.

3) Connect the charge hose of handle hi connection to the vacuum pump.

4) Fully open the handle Lo of the manifold valve.

5) Operate the vacuum pump to evacuate.

6) Make evacuation for 30 minutes and check

whether the compound meter indicates -

0.1Mpa(14.5Psi). If the meter does not indicate -0.1Mpa(14.5Psi) after pumping 30 minutes, it should be pumped 20 minutes more. If the pressure can’t achieve -

0.1Mpa(14.5Psi) after pumping 50 minutes, please check if there are some leakage points. Fully close the handle Lo valve of the manifold valve and stop the operation of the vacuum pump. Confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump).

7) Turn the flare nut of the 3-way valves about

45° counterclockwise for 6 or 7seconds after the gas coming out, then tighten the flare nut again. Make sure the pressure display in the pressure indicator is a little higher than the atmosphere pressure. Then remove the charge hose from the 3-way valve.

When the AC run in mute mode, the compressor will run with low frequency. When the current is more than setting value, the current protection function will be activated and the compressor will stop.

8.4.3.2 Outdoor fan running rules

The outdoor unit will be run at different fan speed according to T4.

For different outdoor units, the fan speeds are different

8.4.3.3 Indoor fan running rules When the compressor is on, the indoor fan can be set to high/med/low/auto/mute. When indoor unit coil temp. is low, the anti-cold air function will start and indoor fan motor will run at low speed, the speed can’t be changed, when the temp. is lower than setting value, the indoor fan motor will stop. When the indoor temp reaches the setting temp., the compressor will stop, the indoor fan motor will run at the minimum speed or setting speed. (The anti-cold air function is valid). The indoor fan is controlled as below:

8.4.3.4 Defrosting mode

AC will enter the defrosting mode according to the value of temp. of T3 and the value range of temp. change of T3 and also the compressor running time. During the defrosting mode, the compressor keeps running, indoor and outdoor motor will stop, defrost lamp of the indoor unit will be

lighted “ .” Will be displayed.

8.4.3.5 Evaporator coil temperature protection

Auto fan action in heating mode:

When evaporator temperature temp. is more than the setting protection value, the compressor will stop.

8.4.4 Auto-mode

This mode can be chosen with remote controller and the setting temperature can be changed between 17°C(62.6°F) ~30°C(86°F). In auto mode, the machine will choose cooling, heating or fan-only mode according to ΔT (ΔT =T1-Ts).

Heating*: For cooling only models, they will run at fan speed

Indoor fan will run at auto fan of the relevant mode. The louver operates same as in relevant mode. If the machine switches mode between heating and cooling, the compressor will keep stopping for certain time and then choose mode according to T1-Ts. If the setting temperature is modified, the machine will choose running function again.

8.4.5 Drying mode

8.4.5.1 Indoor fan speed is fixed at breeze and can’t be changed. The louver angle is the same as in cooling mode.

8.4.5.2 Low indoor room temperature protection In drying mode, if room temperature is lower than 10°C (50°F), the compressor will stop and not resume until room temperature exceeds 12°C (53.6°F).

8.4.5.3 Evaporator anti-freezing protection, condenser high temperature protection and outdoor unit frequency limit are active and the same as that in cooling mode.

8.4.5.4 The outdoor fan operates the same as in cooling mode.

8.4.6 Forced operation function

8.4.6.1 Enter forced operation function: When the machine is off, pressing the touch button will carry the machine to forced auto mode. If pressing the button once again within 5 seconds, the machine will turn into forced cooling mode. In forced auto, forced cooling or any other operation mode, pressing touch button will turn

off the machine.

8.4.6.2 In forced operation mode, all general protections and remote control are available.

8.4.6.3 Operation rules: Forced cooling mode: The compressor runs at F2 frequency and indoor fan runs as breeze. After running for 30 minutes. the machine will turn to auto mode as 24°C (75.2°F) setting temperature. Forced auto mode: The action of forced auto mode is the same as normal auto mode with 24°C (75.2°F) setting temperature.

8.4.7 Auto-Restart function

The indoor unit is equipped with auto-restart function, which is carried out through an autorestart module. In case of a sudden power failure, the module memorizes the setting conditions before the power failure. The unit will resume the previous operation setting (not including swing function) automatically after 3 minutes when power returns. If the memorization condition is forced cooling mode, the unit will run in cooling mode for 30 minutes and turn to auto mode as 24°C (75.2°F) setting temp. If AC is off before power off and AC is required to start up now, the compressor will have 1-minute delay when power on. Other conditions, the compressor will have 3 minutes delay when restarts.

8.4.8 Refrigerant Leakage Detection

With this new technology, the display area will show “EC” when the outdoor unit detects refrigerant leakage.

8.4.9 8°C Heating(optional)

When the compressor is running, the indoor fan motor will run without anti-cold air function. When the compressor is off, the indoor fan motor is off
