terminals are not influenced by external force. Poor connection may cause fire.

• The electric box cover must be mounted and secured in position, otherwise fire or electrical shock may

occur because of dust or moisture.

• All models must be connected to mains power with system impedance limitations.

• While installing the unit, please see the following table for impedance information or contact the utility

company.

Installation of the drain joint (only for heat pump

type)

• Insert the outdoor double-channel drain joint in one of

the bottom holes of the right size then connect the drain

hose and joint together.

Connecting pipe joint

• Use some airproof oil to cover the joint and the expanding orifice of the connecting pipe.

• Align the centre of the joint with that of the expanding orifice and tighten the nut of the connecting pipe

with a wrench. (Adjust the torque using the same method used for connecting the pipe for the indoor

unit.)

Expelling air

• Screw down the cap of both the gas shut-off valve

and the liquid shut-off valve as well as the nut of the

service port.

• Use an Allen wrench to turn the liquid shut-off valve

90° counterclockwise, and close it again after 10

seconds.

• Use soapy water to check for gas leakage, especially

at all joints. If there is no gas leakage, turn the liquid

shut-off valve 90° counter-clockwise again.

• Press the cork of the service port at the gas shut-off

valve. After 10 seconds, a foggy gas is discharged,

meaning the air inside has been expelled.

• Use an Allen wrench to turn both the liquid shut-off

valve and the gas shutoff valve counter-clockwise

until they are fully open and then replace the valve

caps and tighten them.

Expansion of the pipe orifice

• Use a pipe cutter to cut off the broken pipe orifice.

• Remove burrs at the cut of the pipe orifice.

• Insert a nut into the pipe and expand the orifice

with specified tools, reamers for example.

• Check the quality of expanding technique.

Adding refrigerant

• If the connecting pipe is longer than 7 metres, add refrigerant as needed. (Cool only type) added

amount A=(Lm-7m) x 15g/m; (Heat pump type) added amount A= (Lm-7m) x 50g/m. (A: amount of

added refrigerant, L: the length of connecting pipe)

• Expel the air following the above-mentioned

method.

• Close the gas shut-off valve, connect the charging

hose (low pressure) to the service valve and then

open the gas shut-off valve again.

• Connect the refrigerant bottle to the charging hose

and then convert it.

• Add the liquid refrigerant as stated in the above

table.

• Disconnect the manifold gauge after turning off the

shut-off valve, and then open the gas shut-off valve

again.

• Tighten the nuts and caps of each valve.

Operation test

• Before testing operation, carefully inspect the wiring again and make sure it is safe.

1. Emergency switch operation: Every time the emergency switch is pressed, the air conditioner runs in

the following order:

Cool only type: Cool → Shut off

Heat pump type: Cool → Heat → Shut off

2. Remote control operation: If the indoor unit beeps when the I/O button is pressed, this indicates the air

conditioner is being operated with the remote control. After that, press every button to test operation.

3. Check switch operation: open the front grille and press the check button. Switch on the power source

to activate the operation test. If the indicator lamps light up first and then go out in succession, the

system is operating normally. If one of the indicator lamps flashes at all times, there is a system

malfunction. Consult the troubleshooting guide immediately.
