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.
1. Determine the location of the wall hole
based on the location of the outdoor unit.
2. Using a 65-mm (2.5”) core drill, drill a hole
in the wall.
NOTE:
When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
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.
Outdoor Unit Installation
If the drain joint comes with a rubber seal
(see Fig. 5.9 - A ), do the following:
1. Fit the rubber seal on the end of the drain joint
that will connect to the outdoor unit.
NOTE: Make sure the water drains to a safe
location where it will not cause water damage
or a slipping hazard.
2. Insert the drain joint into the hole in the base
pan of the unit.
3. Rotate the drain joint 90° until it clicks in place
facing the front of the unit.
4. Connect a drain hose extension (not included)
to the drain joint to redirect water from the
unit during heating mode.
If the drain joint doesn’t come with a rubber
seal (see Fig. 5.9 - B ), do the following:
1. Insert the drain joint into the hole in the base
pan of the unit. The drain joint will click in
place.
2. Connect a drain hose extension (not included)
to the drain joint to redirect water from the
unit during heating mode.
