Step 3: Drill wall hole for connective piping
1. Determine the location of the wall hole based
on the position of the mounting plate. Refer
to Mounting Plate Dimensions.
2. Using a 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 5mm to 7mm
(0.2-0.275 in). This will ensure proper water
drainage.
3. 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.
