Step five: connect the outdoor electrical cable

1. Remove the wire clip. Connect the power cable and the signal control cable (only for cooling and heating units) to the wiring terminal according to colour. Secure them with the screws.

1. Secure the power cable and the signal control cable with the clip (only for cooling and heating units).

N.B.: • Once you have tightened the screw, pull on the power cable gently to check it is secure.

- Never cut the power cable to extend or reduce the distance.

Step six: tidy up the pipes

1. The pipes should be routed along the wall, bent only as much as is necessary and, if possible, hidden from view. Minimum pipe bending radius: 10 cm.
2. If the outdoor unit is higher than the hole in the wall, you must create a U-bend in the pipe before it enters the room to prevent rain from getting into the room.

- The height of the drain pipe through the wall must not be greater than the height of the hole for the indoor unit's outlet pipe.

- Slant the drain pipe slightly downwards. The drain pipe must not be bent, raised, twisted, etc.

• To ensure uniform drainage, the water outlet must not be placed in water.

Using the vacuum pump

• Remove the valve caps of the liquid valve and gas valve and remove the nut of the refrigerant charge port.
• Connect the piezometer charge pipe to the refrigerant charge bore of the gas valve. Then connect the other charge pipe to the vacuum pump.
• Open the piezometer completely and let it run for 10 – 15 minutes to check if the pressure of the piezometer remains at -0.1 MPa.
• Close the vacuum pump and maintain this condition for 1 – 2 minutes to check if the pressure of the piezometer remains at -0.1 MPa. If the pressure falls, there may be a leak.

• Remove the piezometer. Fully open the plunger of the liquid valve and gas valve with the inner hex key.
• Tighten the screw caps of the valves and refrigerant charge port.
• Reinstall the handle.

Leak detection

Check for leaks using a leak detector. If you do not have a leak detector you can use soapy water.

Post-installation checks

Checks Possible fault
Has the unit been installed securely? The unit could fall, move or produce excessive noise.
Is the thermal insulation of the pipes sufficient?	Risk of condensation and dripping water.
Does the water drain properly? Risk of condensation and dripping water.
Does the supply voltage match the voltage indicated on the data plate?	Risk of malfunction or damage to components.
Have the piping and electrical wiring been installed correctly?	Risk of malfunction or damage to components.
Has the unit been properly earthed? Risk of electric leakage.
Does the power cable meet requirements? Risk of malfunction or damage to components.
Are there any obstructions at the air inlet or outlet? The cooling (heating) capacity may be insufficient.
Have the dust and other particles produced during installation been removed?	Risk of malfunction or damage to components.
Are the gas valve and liquid valve of the connecting tube fully open?	The cooling (heating) capacity may be insufficient.

Connect the power and press the ON/OFF button on the remote control to start operation. Press the MODE button to select AUTO, COOL, DRY, FAN and HEAT mode and check the air conditioner operates normally. If the ambient temperature is below 16°C, the air conditioner will be unable to start cooling.

Piping configuration

1. Standard connecting tube length: 5 m.

2. Minimum connecting tube length: 3 m.

3. Maximum connecting tube length and maximum height difference:

Capacity	Maximum connecting tube length	Maximum height difference
9000Btu/h	15	10
12000Btu/h	20	10
18000Btu/h	20	10

Warning! Note the additional charge on the data plate affixed to the outdoor unit.

Additional oil and refrigerant charging

- If the length of the connecting pipe is increased by 10 m compared to the standard length, add 5 ml of refrigeration oil for every 5 m of pipe added.

- Method for calculating the amount of additional refrigerant charge (liquid pipe): amount of additional refrigerant charge = additional length of liquid pipe x additional amount of refrigerant charge per metre.

Φ6.35 9.52 or	12Φ Φ	20
Φ6.35 15.88	Φ	50

Procedure for extending the piping

N.B.:

Improper extension of piping is the main cause of refrigerant leaks. Proceed as shown below:

1. Cut the pipe

- Check the length of the pipe based on the distance between the indoor unit and outdoor unit.

- Cut the required pipe using a pipe cutter.

5. Expand the port

Expand the port using a pipe expander.

- Remove burrs with a file, ensuring they do not go into the pipe.

3. Secure an insulating tube

4. Install a union nut

- Remove the union nut on the indoor connecting pipe and outdoor valve. Install the union nut on the pipe.

- "A" varies according to diameter:

Outdoor diameter (mm)	A (mm)
	Max.	Min.
6.35 (1/4") 1.3 0.7
9.52 (3/8") 1.6 1.0
12.7 (1/2") 1.8 1.0
15.88 (5/8") 2.4 2.2

6. Inspection

Check the quality of the expanded port. If defective, expand the port again following the procedure described above.
