Notes On Drilling Hole In Wall
You must drill a hole in the wall for the
refrigerant piping, and the signal cable that will
connect the indoor and outdoor units.

Determine the location of the wall hole
1.
based on the location of the outdoor unit.
Using a 65-mm (2.5") core drill, drill a hole
2.
in the wall.
NOTE: When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
Place the protective wall cuff in the hole.
