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.
CAUTION
When drilling the wall hole, make
sure to avoid wires, plumbing, and
other sensitive components.
