Drainpipe
Installation
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.
