CONNECTING CONDENSATE DRAIN LINE
Install the drainpipe of the indoor unit
You can use a polyethylene tube as the drain pipe (out-dia.37-39mm, in-dia.32mm).
The drain pipe is filed supplied.
Set the mouth of the drain pipe onto the root of the body's pump-pipe, and clip the drain pipe and
the out-let pipe sheath (fittings) together firmly with the out-let pipe clasp (fitting).
The body's pump pipe and the drain pipe (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 drain pipe down toward
outdoor (outlet-side) at a degree of over 1/ 50.
And please avoid any bulge or water deposit
see figure (a).
Do not drag the drain pipe 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. see figure (b).
Or you can tie the drain pipe with the
connecting pipe to it. see figure (c).
In the case of prolonged drain pipe, you had better tighten its indoor part with a protection tube to
prevent it from loosing.
If the outlet of the drain pipe 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.
The end of the drain pipe 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.
Drainage test
Check whether the drain pipe 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.
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 from the joints.
3)
Stop the air conditioner, turn off the power, and reset the test
cover to its original position.
Note : 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.
