3.
Using a 65mm (2.5in) or 90mm(3.54in) 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 once you finish
installation.
Outdoor
≈ 12mm / 0.5 inch
NOTE: When drilling the 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.

Check whether the drainpipe is unhindered.
This test should be performed on newly built
houses before the ceiling is paved.
