• The power wires and signal wires between the indoor/outdoor units must be connected one by one as
per corresponding number on the wiring terminal board.
• The connecting cables must be clipped together.
• Special cable must be used to connect indoor unit and outdoor unit. It should be ensured that the
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.
