Units with a pump:
Drainage test
Check whether the drainpipe is
unhindered. This test should be per-
formed on newly built houses before
the ceiling is paved.
Units without a pump:
1. Remove the test cover. Fill the water
pan with 2 liters of water.
2. Turn on the unit in COOLING mode.
You will hear the drain pump. Check
whether the water is discharged
properly (a 1-minute lag is possible,
depending on the length of the
drain pipe). Check whether water
leaks from the joints.
3. Turn off the air conditioner and put
the cap back on.
3. 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.
