Step 3: Drill wall hole for connective piping
1. Determine the location of the wall
hole based on the location of the out-
door unit.
2. Using a 65mm (2.56") or 90mm
(3.54") (depending on models) 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.
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.
