Manual

Installing the Outdoor Unit

1. Install the drain port and drain hose (for the

heat pump model only).

The condensate drains from the outdoor unit

when the unit is in operation. In order not to

disturb your neighbourhood area and

protect the environment, install a drain port

and drain hose to direct the condensate

water.

2. Install and x the outdoor unit.

Fix it with bolts and nuts tightly on a at and strong oor. If the supporter is

mounted on a wall or roof, make sure it is securely fastened to prevent it

from swaying in the event of severe vibrations or high winds.

3. Outdoor unit piping connection.

Remove the valve caps from the 2-way and 3-way valves. Connect the pipe

to the 2-way and 3-way valves separately according to the required torque.

4. Outdoor Unit cable connection (see the previous page).

Air Purging

The air, which contains moisture from the refrigeration cycle, may cause a

malfunction in the compressor. After connecting the indoor and outdoor units,

evacuate air and moisture from the system using a vacuum pump. Follow the

given steps for air purging:

1. Unscrew and remove the caps from the 2-way and 3-way valves.

2. Unscrew and remove the cap from the service valve.

3. Connect the vacuum pump’s exible hose to the service valve.

4. Start the vacuum pump for 10-15 minutes until the vacuum reaches

10mmHg absolute level.

5. With the vacuum pump still running, close the low-pressure knob on the

vacuum pump manifold. Then stop the vacuum pump.

6. Open the 2-way valve 1/4

turn, then close it after 10 seconds. Check the

tightness of all joints using liquid soap or an electronic leak detector.

7. Close 2-way and 3-way valves fully. Disconnect the vacuum pump exible

hose

8. Retighten all the valve caps on their respective valves.

• Do not modify the length of the power supply cord or use an extension cord

to power the unit.

• Do not share the electrical outlet with other appliances. An improper or

insuﬃcient power supply can cause a re or an electrical shock.

• The product must be properly earthed at the time of installation to prevent

electrical shocks.

• For all electrical work, follow all local and national wiring standards and

regulations and the user manual. Connect the cables tightly, and clamp

them securely to prevent external forces from damaging the terminal.

Improper electrical connections can overheat and cause res or electric

shocks. All electrical connections must be made according to the Electrical

Connection Diagram located on the panels of the Control Box unit.

• All wiring must be properly arranged to ensure that the Control Board Cover

can be closed properly. Failure to do that can lead to corrosion and cause the

connection points on the terminal to heat up, catch re or cause electrical

shock.

Warning for Product Use

• In abnormal situations (like a burning smell), immediately turn Oﬀ the unit

and disconnect the power.

• Do not insert ngers, rods or other objects into the Air Inlet or Outlet. This

may cause injury, given the fan may be rotating at high speeds.

• Do not use ammable sprays such as hair spray, lacquer or paint near the

unit. This may cause res or burns.

• Do not operate the Air Conditioner near or around combustible gases.

Emitted gases may collect around the unit and cause an explosion.

• Do not operate your Air Conditioner in wet areas such as bathrooms or

laundry rooms. Too much exposure to water can cause short circuits.

• Do not allow children to play with the Air Conditioner. Children must be

supervised around the unit at all times.

• If the Air Conditioner is used along with burners or other heating devices,
