Drainage test
Check whether the drainpipe is unhindered.
New built house should have this test done
before paving the ceiling.
The unit with pump.
The unit without pump.
1. Remove the test cover, and stow about
2000ml water to the water pan.
2. Operate the air conditioner in "COOLING"
mode. The sound of the drain pump shall be
heard. Check whether the water is
discharged well (1 min lag is possible,
according to the length of the drain pipe),
and check whether the water leaks from the
joints.
3. Power off the air conditioner and recover
the cap.
3.
Using a 65-mm (2.5”) core drill, drill a hole in
the wall. Make sure that the hole is drilled at
a slight downward angle, so that the outdoor
end of the hole is lower than the indoor end
by about 12mm (0.5”). This will ensure proper
water drainage (See Fig. 6.5). Place the
protective wall cuff in the hole. This protects
the edges of the hole and will help seal it
when you finish the installation process.

NOTE:
When drilling the wall hole, make sure
to avoid wires, plumbing, and other sensitive
components.
4.
Pass the drain hose through the wall hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slipping hazard.
NOTE:
The drainpipe outlet should be at least
5cm (1.9”) above the ground. If it touches the
ground, the unit may become blocked and
malfunction. If you discharge the water directly
into a sewer, make sure that the drain has a U
or S pipe to catch odors that might otherwise
come back into the house.
