Step 4:
Drill wall hole for connective piping
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65mm (2.5in) or 90mm(3.54in) (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 (0.5in). 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.
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive.
