Drainage Test
Check that the drainpipe is unhindered.
This test should be performed on newly built
houses, before the ceiling is paved.
Units WITH a Pump.
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 work . 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 o the air conditioner, and put the cap
back on.
3. Using a 65-mm (2.5”) core drill, drill a hole into
the wall. Be sure that the hole is drilled at
a slightly downward angle, so that the outdoor
end of the hole is lower than the indoor end
by about 12-mm (0.5”). This will ensure proper
water drainage (See Fig. 6.5). Place the
protective wall cu into the hole. This protects
the edges of the hole, and will help seal it
once installation is completed.

NOTE: When drilling the hole, be 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.
