NOTE: The minimum distance between the
outdoor unit and the walls described in the
installation guide does not apply to airtight
rooms. Be sure to keep the unit unobstructed
in at least two of the three directions (M, N, P)
(See Fig. 6.8)

Drain Joint Installation
Before bolting the outdoor unit in place, you
must install the drain joint at the bottom of the
unit. (See Fig. 6.9)
1. Fit the rubber seal on the end of the drain
joint where it will connect to the outdoor
unit.
2. Insert the drain joint into the hole in the
base pan.
3. Rotate the drain joint 90° until it clicks in
place and faces the front of the unit.
4. Connect a drain hose extension (if
included) to the drain joint, to redirect water
from the unit during heating mode.
NOTE: Make sure the water drains into a safe
location where it will not cause water damage
or a slipping hazard.

Notes On Wall Hole Drilling
You must drill a hole in the wall for the refrigerant
piping and 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 (2-1/2") core drill, drill a hole
into the wall.
NOTE: When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
3. Place the protective wall sleeve into the
inside part of the hole. This protects the
edges of the hole and helps seal it when
you finish the installation process.
When Selecting a 24K Indoor Unit (5 zone only)
The 24K indoor unit can only be connected with
a 5-zone system. If there is one 24K indoor unit,
connect it to Circuit A. If there are two 24K
indoor units, connect them to circuits A and B only.
(See Fig. 6.10)
