Caution: Before installing the electrical equipment, please pay attention to the following
matters which have been specially pointed out by our designers:
1. Check that if the power supply used conforms to the rated power supply specified on the nameplate.
2. The capacity of the power supply must be large enough. The section area of fitting line in the room
shall be larger than 2.5 mm
2
.
3. The lines must be installed by professional personnel.
An electricity leakage protection switch and an air switch with gap between electrode heads
larger than 3 mm shall be installed in the fixed line.
1. Connection of single wire
(1) Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.
(2) Remove the screw at the terminal board of the air-conditioning unit.
(3) User 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.
2. Connection of multiple twisted wires
(1) Use wire stripper to strip the insulation layer (10mm long) from the end of the multiple twisted
wires.
(2) Remove the screw at 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.
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 connections.
Connection of Signal Line of Wire Controller
1. Open the cover of the electric box of the indoor unit.
2. Pull the signal cable of the wire controller through the rubber ring.
3. Plug the signal line of the wire controller onto the 4-bit pin socket at the circuit board of the indoor
unit.
4. Use cable fastener to bundle and fix the signal cable of the wire controller.
