7. WIRING
Specified power cables should be used. Do not apply any
pressure on the terminals used to connect.
Improper connection may cause fire.
Grounding must be properly done.
The grounding wire should be away from gas pipes, water
pipes, telephone, lightening rods or other grounding wires.
Improper grounding may cause electric shock.
Electric Wiring must be done by professionals. Use a
separate circuit according to national regulations.
If the wiring capacity is not enough, electric shock or fire may
occur.
CAUTION
1. Be sure to Install Current Leakage Protection Switch, or
electric shock may occur.
2. Power cord is to be selected according to national regula-
tions.
3. Outdoor unit power cord should be selected and connected
according to the outdoor unit installation manual.
4. Wiring should be away from high temperature components,
or the insulation layer of the wires may melt down.
5. Use wire clamp to fix the wires and terminal block after
connection.
6. Control wire should be wrapped together with heat insulated
refrigerant pipes.
7. Connect the indoor unit to power only after the refrigerant
has been vacuumed.
8. Don’t connect the power wire to the signal wire connection
end.

Bend the pipe with thumb
Min-radius 100mm
Make the ends straight
2. Locate The Pipe
1) Drill a hole in the wall (suitable just for the size of the wall
conduit, 90mm in general), then set on the fittings such as the wall
conduit and its cover.
2) Bind the connecting pipe and the cables together tightly with
binding tapes. Do not let air in, which will cause water leakage by
condensation.
3) Pass the bound connecting pipe through the wall conduit from
outside. Be careful of the pipe allocation to do no damage to the
tubing.
3. Connect the pipes.
4. Then, open the stem of stop valves of the outdoor unit to make
the refrigerant pipe connecting the indoor unit with the outdoor unit
fluently flow.
5. Be sure of no leakage by checking it with leak detector or soap
water.
6. Cover the joint of the connecting pipe to the indoor unit with the
soundproof/insulating sheath (fittings), and bind it well with the
tapes to prevent leakage.
CAUTION
The drain pipe of indoor unit must be heat insulated, or it will
condense dew, as well as the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make
sure there is no leakage.
6. CONNECT THE DRAIN PIPE
6.1 Install the drainpipe of the indoor unit
The outlet has PTI screw bread, Please use sealing materials
and pipe sheath(fitting) when connecting PVC pipes.
6.2 Drainage test
Check whether the drainpipe is unhindered.
New built house should have this test done before
paving the ceiling.
With the connection part to the indoor unit, please be noted not
to impose pressure on the side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100,
there should not be any winding.
The total length of the drain pipe when pulled out traversely
shall not exceed 20m, when the pipe is over long, a prop stand
must be installed to prevent winding.
Refer to the Fig.6-1 for the installation of the pipes.
