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 cu in the hole. This protects 
the edges of the hole and will help seal it 
when you nish 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.
