Electrical installation

Caution:
Before installing the electrical equipment, take care on the following matters.
• Check if the power supply is identical to the ratings on the nameplate.
• The capacity of the power supply must be large enough.
• Use a cable which is not lighter than polychloroprene sheathed flexible cord (code designation
60245 IEC 57).
• Make sure the power cable is secured in place and that the wiring terminal are free of any ex-
cess force from the cable.
• For electric wiring, refer to WIRING DIAGRAM attached to the unit body.
Single wire connection
 Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.
2 Remove the screw from the terminal board of the air-conditioning unit.
3 Use pliers to bend the end of the single wire so that a loop matching the screw size is formed.
4 Put the screw through the loop of the single wire and fix the loop at the terminal board.
Multiple twisted wires connection
 Use wire stripper to strip the insulation layer (0mm long) from the end of the multiple twisted
wires.
2 Remove the screw from the terminal board of the air-conditioning unit.
3 Use crimping pliers to connect a terminal (matching the size of the screw) at the end of the
multiple twisted wires.
4 Put the screw through the terminal of the multiple twisted wires and fix the terminal at the
terminal board.
Warning:
If the power supply flexible line or the signal line of the equipment is damaged, only use special
flexible line to replace it.
• Before connecting lines, read the voltages of the relevant parts on the nameplate. Then carry
out line connection according to the schematic diagram.
• The air-conditioning unit shall have special power supply line which shall be equipped with
electricity leakage switch and air switch, so as to deal with overload conditions.
• The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
• All fitting lines must use crimp terminals or single wire. If multiple twisted wires are connected
to terminal board, arc may arise.
• All line connections must conform to the schematic diagram of lines. Wrong connection may
cause abnormal operation or damage of the air-conditioning unit.
• Do not let any cable contact the refrigerant pipe, the compressor and moving parts such as fan.
• Do not change the internal line connections inside the air-conditioning unit. The manufacturer
shall not be liable for any loss or abnormal operation arising from wrong line connections.
Power cable connection
 Remove the front-side panel of the outdoor unit.
2 Pass the cable though rubber ring.
3 Connect the power supply cable to the "L, N" terminals and the grounding screw.
4 Fix the cable with cable fastener.

• If the power cable is longer than 5 meters, please enlarge the cross section of power cable
adequately, in order to avoid the accident due to overload.
