overflowing out from the drainage pipe, separate the drainage pipe from the connecting pipe and the cables.
(2) Use thermal insulation tape to wrap the pipes from the bottom of the outdoor unit to the upper end of the
pipe where the pipe enters the wall. When wrapping thermal insulation tape, the later circle of tape must
cover half of the front circle of tape (refer to Fig. 11-19).
(3) Wrapped pipe must be fixed to wall by pipe clamps.
CAUTIONS:
(1) Do not wrap the protective tape too tight, otherwise the efficiency of thermal insulation may be weakened.
Ensure that the condensate drainage flexible tube be separated from the bundled pipes.
(2) After the protective work is completed and the pipes are wrapped, block the hole in the wall with seal
materials, so as to prevent rain and wind from entering the room.
F. Power Cable Connection
CAUTION:
Before installing the electrical equipment, please pay attention to the following matters specially pointed out
by our designers:
(1) Check if the power supply conforms to the rated one specified on the nameplate.
(2) The capacity of the power supply must be large enough. The section area of the power cord in the room
should be larger than 2.5 mm
2
.
(3) The lines must be installed by professionals.
WAR N IN GS:
If the flexible line of the power supply 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 should have special power supply line equipped with electricity leakage switch and
air switch, so as to deal with overload conditions.
（3）The air-conditioning unit must be earthed to avoid a hazard due to insulation failure.
（4）All 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 to the air-conditioning unit.
（6）Do not let any cable contact the refrigerant pipe, the compressor or moving parts such as fan.
（7）Do not change the internal line connections inside the air-conditioning unit, or the manufacturer should not be
liable for any loss or abnormal operation arising from wrong line connections.
Connection of the Power Cable
1. Air-conditioning unit with single-phase power supply
(1) Remove the front 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.
