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. 6.4).
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 pro-
cess.
Outdoor
=12mm/0.5 inch
NOTE: When drilling the hole in the wall,
make sure to avoid wires, plumbing, and oth-
er sensitive components.
4. Pass the drain hose through the hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slippage.
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 direct-
ly into a sewer, make sure that the drain has a
U or S pipe to prevent unwanted odors from
entering the house.
