5.2 Connect Wiring to the Terminals
Caution:
Please note the following items before installing the electric appliance.
(1) Check if the power supply accords with its value on the nameplate.
(2) The capacity of the power supply must be large enough.
(3) The circuit should be installed by the professional technician.
(4) In fixed circuit, there must be electricity leakage protection switch of enough power capacity
and air switch with space between its electrode contacts ≥ 3mm.
(5) Single wire connection.
①
Peel off the insulation for 25mm with pliers.
②
Remove the screw from the terminal board.
③
Bend the peeled wire into circle with pliers.
④
Screw cross the circle and fix it on the terminal board.
(6) Strand wires connection.
①
Peel off the insulation for 10mm with pliers.
②
Remove the screw from the terminal board.
③
Clamp a round terminal of the peeled wires.
④
Screw cross the circle and fix it on the terminal board.

Warning:
If the power line or the signal line is defective, use the special coil to replace it.
(1) Before connecting lines, read the voltages of the relevant parts on the nameplate. Then
carry out line connection according to the schematic diagram.
(2) 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.
(3) The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
(4) All fitting lines must use crimp terminals or single wire. If multiple twisted wires are
connected to terminal board, arc may arise.
(5) All line connections must conform to the schematic diagram of lines. Wrong connection may
cause abnormal operation or damage of the air-conditioning unit.
(6) Do not let any cable contact the refrigerant pipe, the compressor and moving parts such as
fan.
(7) 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
