1. Fit the rubber seal on the end of the drain joint
that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the bas
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. 6 .9 - B ), do the following:
1. Insert the drain joint into the hole in the bas
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.
You must drill a hole in the wall for the refriger-
ant 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 2.5” hole bit, drill a hole in the wall.
3. Place the protective wall cu in the hole. This
protects the edges of the hole and helps seal
it when you nish the installation process.
The 24K indoor unit can only be connected with
a 36k or 48k condenser due to refrigerant pipe
diameter. Use connection A on the 36k and
connections A&B on the 48k. (See Fig. 6.10)
