NOTE:
The minimum distance between the
outdoor unit and 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. 4.10)

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.

Drain Joint Installation
If the drain joint comes with a rubber seal
(see Fig. 4.12 - A ), do the following:
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 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. 4.12 - B ), do the following:
Insert the drain joint into the hole in the base
pan of the unit. The drain joint will click in
place.
Connect a drain hose extension (not included)
to the drain joint to redirect water from the
unit during heating mode.

The drainpipe is used to drain water from the
unit. Improper installation may cause unit and
property damage.
CAUTION
•
Insulate all piping to prevent condensation,
which could lead to water damage.
•
If the drainpipe is bent or installed
incorrectly, water may leak and cause a
malfunction of the water- level switch.
•
In HEAT mode, the outdoor unit will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage due to frozen
drain water.
•
DO NOT
pull the drainpipe forcefully as
this could cause it to disconnect.
NOTE ON PURCHASING PIPES
This installation requires a polyethylene tube
(outside diameter = 2.5cm), which can be
obtained at your local
hardware store or from your dealer.
Indoor Drainpipe Installation
Install the drainpipe as shown in Fig 5.2.
1. Cover the drainpipe with heat insulation to
prevent condensation and leakage.
2. Attach the mouth of the drain hose to the
unit’s outlet pipe. Sheath the mouth of the
hose and clip it firmly with a pipe clasp.
