The incline of attached drain hose should be 75mm (3inch) or less so that the drain outlet
does not have to withstand additional force.
10. Blowhole setting
➢

of main pipe to ensure the condensate water discharge smoothly.

Blowhole
11. 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 (as shown). 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.
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: When drilling the wall hole, make sure to avoid wires, plumbing, and other sensitive
components.
The drainpipe outlet should be at least 50mm (1.9") above the ground. If it touches the ground,
the unit may become blocked and malfunction.
