Pump-pipe clasp
(the fittings)
1. Install the drainpipe of the indoor unit
You can use a polyethylene tube as the drainpipe (out-dia.37-39mm, in-dia.32mm). It could be
bought at local market or from your dealer.
Set the mouth of the drainpipe onto the root of the body's pump-pipe, and clip the drainpipe and the
out-let pipe sheath (fittings) together firmly with the out-let pipe clasp (fitting).
CAUTIONS:
Use your strength carefully to prevent the pump-pipe from breaking.
The body's pump pipe and the drainpipe (especially the indoor part) should be covered evenly with
the out-let pipe sheath (fittings) and be bound tightly with the constrictor to prevent condensation
caused by entered air.
To prevent water from flowing backwards into the air conditioner while the air conditioner stops,
please lean the drainpipe down toward outdoor (outlet-side) at a degree of over 1/ 50. And please
avoid any bulge or water deposit.( Refer to Chart 28.a)
Do not drag the drainpipe violently when connecting to prevent the body from being pulled. Mean-
while, one support-point should be set every 1~1.5m to prevent the drainpipe from yielding (Refer
to Chart 28.b). Or you can tie the drainpipe with the connecting pipe to fix it.(Refer to Chart 28.c)
In the case of prolonged drainpipe, you had better tighten its indoor part with a protection tube to
prevent it from loosing.
If the outlet of the drainpipe is higher than the body's pump joint, the pipe should be arranged as
vertically as possible. And the lift distance must be less than 200mm, otherwise the water will
overflow when the air conditioner stops.( Refer to Chart 29)
The end of the drainpipe should be over 50mm higher than the ground or the bottom of the drainage
chute, and do not immerse it in water. If you discharge the water directly into sewage, be sure to
make a U-form aquaseal by bending the pipe up to prevent the smelly gas entering the house
through the drain pipe.
