10. CONNECT THE DRAIN PIPE

Install indoor unit drain pipe
For 400 to 560 indoor unit, please use water connecting pipe and
Adhesive tape for seal when connecting drain pipes.
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.
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 win ding.
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.
The height difference between drain pipe end to ground or drain
channel should be more than 50mm, and the drain pipe cannot
put in water. If the drain water was discharged to ditch directly,
the drain pipe must be upward bent into a U type water seal to
avoid odor into the interior through the drain pipe.
If the negative pressure of drain pan outlet is high, there must
be a water elbow in drain pipe to avoid poor drain or blow water
for negative pressure. Please install the water elbow as figure
4.4 shown, each unit should install a water elbow. There should
be a plug in water elbow for convenient cleaning.
Refer to the figures on the right for the installation of the pipes.

Caution: While connecting the drain pipe, please use the drain pipe con-
nect to the secondary water holder simultaneously, for avoiding
there are little condensate water deposit in the unit when the machine
is running under the high humidity working condition.

11. WIRING

Attaching wiring
●
The air conditioner should use separate power supply with rated
voltage.
●
The external power supply to the air conditioner should have
ground wiring, which is linked to the ground wiring of the indoor
and outdoor unit.
●
The wiring work should be done by qualified persons according
to circuit drawing.
●
A leakage protector should be installed according to the National
Standard concerning electrical appliance.
●
Be sure to locate the power wiring and the signal wring well to
avoid cross-disturbance and their contact with connecting pipe
or stop value body.
●
The wiring attached to this air conditioner is 10m long. Be sure
to prolong it with wiring of the same type and proper length
if necessary. Generally, do not twist two wiring together unless
the joint is soldered well and covered with insulator tape.
● Do not turn on the power until you have checked carefully after
wiring.

Communication Wiring Chart
Communication wiring will be different according to the horse-
power of air-condictioners. The wiring of 450 to 560 indoor
unit, please refer to Fig.11-1.
