Installation and Maintenance 

SERVICE MANUAL

2) Earthing Requirements

otherwise it would cause the hazard of electric shock.

●

The reliable earth terminal should be provided and the earth wire can not be connected to any of the

following places.

①

Running water pipe; 

②

Coal gas pipe; 

③

Sewage pipe; 

④

Other places where the professional personnel think unreliable.

3) Electrical Cable Connection
Cautions!

①

 . The mistake connecting line will result in malfunction. After the electrical wiring working, ensure the wire between the connection

②

 . The connection piping and connection line of each indoor unit should connect well according to the instruction.

③

 . The electric installation should be carried out by the technician as instructed by the local laws, regulations and also this manual.

④

 . The installation location should be dry, and can't be expose in direct sunlight or strong breeze.

⑤

 . Have to install a breaker in the circuit that can shut off the main power supply of the system. Besides, the air switch coupled with the

leakage current protection switch must be equipped.

4) Wiring of the Power Cord
a. Open the side plate.
b. Connect the power card to the terminals “L1”, “L2” and also the earthing bolt, and then connect the wiring terminals “N(1),2,3” of the
indoor unit to those of the outdoor unit correspondingly.
c. Fix the power cord with wire clips.
d. Let the power cord go through the rubber ring.
