Attention:
Be careful! Do not misconnect the wires or it will cause the air
conditioner can’t work normally, or cause fuses blown out or
other serious accidents.
The method of installation is as the diagram indicates, connect the power wires according to the
stipulated fixed colour and order.
a. Distinguish the colour, order and diameter of wires clearly while installation,the power wires
between the indoor unit and the outdoor unit must be corresponding with each other, never
be misconnected.
b. The yellow-green( ) wire is the wire connecting to earth, it must be connected to the earth
reliablly or it will cause electricity shock.
c. After installation, the wires must be pressed tightly with the wire clip, or it will cause
serious accidents. Before press the wire, pull straight the wire, bind the remainder wire
at the suitable place out of the unit to avoid being worn.
d. The screws of terminals must be screwed tightly, make sure they are firm by pulling the wires
gently after screwing them.
e. Please add some connecting wires if the connecting wires are not long enough, the diameter
of the wire must fit the stipulation and the colour must be the same.
4. Test Run
4-1 Pipe-cleaning and Taking Vacuum
Make sure all the pipe joints have been screwed tightly according to the fixed wring torque,then
engage in the pipe-cleaning and taking vacuum operation.
1. Remove the valve core copper caps of the high pressure valve and the low pressure valve.
2. Remove copper cap of refrigerant-adding valve, take vacuum with vacuum pump, and the \
vacuum value should be less than 10Pa.
3. Fasten the copper cap of refrigerant-adding valve.
4. Loose the high pressure valve and low pressure valve all(anti-clockwise).
5. Use the leakage detector or soapy water to check the system pipe joint and valve cap for
leakage.
6. If there is no leakage, cover the copper caps of valve cores(the must be screwed tightly).
3-5 Installation of the outdoor drain pipe
Insert the catchment trough into the hole of the base, connect an extended pipe to the trough.
Note: The drained water should not affect neighbours. (not available for the cooling type).
