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.

Take great care when carrying out the following connections, so as to avoid malfunction of
the air-conditioning unit because of electromagnetic interference.
The signal line of the wire controller must be separated from the power line and the
connecting line between the indoor unit and the outdoor unit.
