NOTE: The minimum distance between the
outdoor unit and walls described in the instal-
lation 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. 5.10)
NOTE: Make sure the water drains to a safe
location where it will not cause water damage
or a slipping hazard.
NOTE: When connecting multiple drainpipes,
install the pipes as shown in Fig 6.3.

Drain Joint Installation
Notes On Drilling Hole In Wall
If the drain joint comes with a rubber seal (see
Fig. 5.12 - A), do the following:
1. Fit the rubber seal on the end of the drain
joint that will connect to the outdoor unit.
The drainpipe is used to drain water from the
unit. Improper installation may cause unit and
property damage.
You must drill a hole in the wall for the refriger-
ant piping, and the signal cable that will con-
nect 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.
Indoor Drainpipe Installation
Install the drainpipe as shown in Figure 6.2.
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.
(Fig 6.1)
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 includ-
ed) 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. 5.12 - 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 includ-
ed) to the drain joint to redirect water from
the unit during heating mode.

Drainpipe Installation
CAUTION
• Insulate all piping to prevent condensation
and 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 = 3.7-3.9cm, inside
diameter = 3.2cm), which can be obtained
at your local hardware store or dealer.
NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe, tighten
the indoor connection with an additional pro-
tection tube to prevent it from pulling loose.
• The drainpipe should slope downward at a
gradient of at least 1 /100 to prevent water
from owing back into the air conditioner.
• To prevent the pipe from sagging, space
hanging wires every 1 -1.5m (39-59”).
• Incorrect installation could cause water to
ow back into the unit and ood it.
