8. INSTALL THE DRAINPIPE
OF THE INDOOR UNIT
• You can use a polyethylene tube as the drainpipe
(out-Ø 37-39mm, in-Ø 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).
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.
Meanwhile, 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.
2. Drainage test
Check whether the drainpipe is unhindered
New built house should have this test done before
paving the ceiling.
1) Remove the test cover, and stow water of about
2000ml to the water receiver through the stow
tube. ( Refer to Chart 30)
2) Turn on the power, and operate the air
conditioner under the "COOLING" mode. Listen to
the sound of the drain pump. Check whether the
water is discharger well (a lag of 1min is allowed
before discharging, according to the length of the
drain pipe), and check whether water leaks
fromthe joints.
CAUTION
If there is any malfunction, please resolve it
immediately.
3) Stop the air conditioner, turn off the power, and
reset the test cover to its original position.
The drain plug is used to empty the water-receiver
for maintenance of the air conditioner. Please stuff
it imposition at all times during operation to avoid
leakage.
3. Drain ElbowInstallation
Fit the seal into the drain elbow, then insert the
drain elbow into the base pan hole of outdoor,
rotate 90° to securely assemble them. Connect
the drain elbow with an extension drain hose
(Locally purchased), in case of the condensate
draining off the outdoor unit during the heating
mode.
