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.
