CAUTION
The drain pipe and connections of the indoor unit must be heat
insulated, or it attracts condensation.
A hard PVC binder must be used to connect the pipes. Ensure
there are no leaks.
6. CONNECTING THE DRAIN PIPE
6.1 Install the drainpipe of the indoor unit
The outlet has a PTI screw bread. Use sealing materials and a
pipe sheath (fitting) when connecting PVC pipes.
6.2 Drainage test
Check whether the drainpipe is unhindered.
Newly built house should be tested before decorating
the ceiling.
When connecting to the indoor unit, do not put pressure on the
side of the indoor unit’s pipes.
Avoid winding when the declivity of the drain pipe in the
downwards direction is over 1/100.
The total length of the drain pipe when pulled out must not
exceed 20 m. When the pipe is too long, install a prop stand to
prevent winding.
Refer to the Fig.8-1 for the installing the pipes.

7. WIRING
Specified power cables should be used. Do not apply any
pressure on the terminals that will be connected.
Improper connection may cause a fire.
Grounding must be properly done.
The grounding wire should be away from gas pipes, water
pipes, telephones, lightning rods or other grounding wires.
Improper grounding may cause electric shocks.
Wiring must be done by professionals. Use a separate
circuit according to national regulations.
If the wiring capacity is not enough, electric shocks 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. An all-pole disconnection device which has at least a 3 mm
separation distance between all poles and a residual current
device (RCD) with a rating above 10 mA must be incorporated
in the fixed wiring according to national regulations.
4. Select and connect outdoor unit power cords according to the
outdoor unit installation manual.
5. Wiring should be away from high temperature components,
or the insulation layer of the wires may melt.
6. Use a wire clamp to fix the wires and terminal block after
connection.
7. Control wire should be wrapped together with heat insulated
refrigerant pipes.
8. Connect the indoor unit to power only after the refrigerant
has been vacuumed.
9. Don’t connect the power wire to the signal wire connection
end.
