8    WIRING

The appliance shall be installed in accordance with 

national wiring regulations.

The air conditioner should use separate power supply 

with rated voltage.

The external power supply to the air conditioner should 

be grounded, which is linked to the ground wiring of the 

indoor and outdoor unit.

The wiring work should be done by qualified persons 

according to wiring diagram.

A circuit breaker and a residual current device (RCD) with 

above 10mA  rating shall be installed in the power circuit 

according  to the national rule.

Be sure to locate the power wiring and the signal wring 

well to avoid cross-disturbance.

Do not turn on the power until you have confirmed 

proper wiring.

The power cord type is H07RN-F.

The power connection for the air conditioner has to be 

done at the main power distribution. The distribution has 

to be of a low impedance, normally the required 

impedance reaches at a 32A fusing point.
No other equipment has to be connected with this power 

line.
For detailed installation acceptance please refer to your 

power supplier, if restrictions do apply for products like 

washing machines, air conditioners or electrical ovens. 
For power details of the air conditioner refer to the rating 

nameplate of the product. 
For any question contact your local dealer.

Please use heat-resistant materials as heat insulation materials 

of the air-side pipe. (e.g., EPT)

Cover heat insulation materials separately at the liquid side and 

the air side. Moreover, perform heat insulation thoroughly for the 

air-side pipes of the indoor unit, and prevent water from dripping 

outside the unit.

After applying the auxiliary heat insulation materials, use 

vinylresin tape to seal it lest water leak.
