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 cu in the hole.
This protects the edges of the hole and will
help seal it when you nish 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.

NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe,
tightenthe indoor connection with an
additionalprotection tube. This prevents
it from pulling loose.
•
The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water
from flowing back into the air conditioner.
• To prevent the pipe from sagging, space
hanging wires every 1-1.5m (39-59”).
• If the outlet of the drainpipe is higher than
the body’s pump joint, use a lift pipe for
the indoor unit’s exhaust outlet. The lift
pipe must be installed no higher than
55cm (21.7”) from the ceiling board. The
distance between the unit and the lift pipe
must be less than 20cm (7.9”). Incorrect
installation could cause water to ow back
into the unit and ood.
The drainpipe is used to drain water away 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
water-level switch malfunction.
• 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.
• DO NOT pull the drainpipe forcefully. This
could disconnect it.
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.

Drainage test
Check whether the drainpipe is unhindered.
This test should be performed on newly built
houses before the ceiling is paved.
Units with a pump.
Units without a pump.
1. Remove the test cover.
Fill the water pan with 2 liters of water.
2. Turn on the unit in COOLING mode. You will
hear the drain pump.Check whether the
water is discharged properly (a 1-minute lag
is possible, depending on the length of the
drain pipe), Check whether water leaks from
the joints.
3. Turn o the air conditioner and put the cap
back on.
3. Using a 65-mm (2.5”) core drill, drill a hole in
the wall. Make sure that the hole is drilled at
a slight downward angle, so that the outdoor
end of the hole is lower than the indoor end
by about 12mm (0.5”). This will ensure proper
water drainage (See Fig. 5.5). Place the
protective wall cu in the hole. This protects
the edges of the hole and will help seal it
once you nish installation.

NOTE: When drilling the hole, make sure to
avoid wires, plumbing, and other sensitive
components.
4. Pass the drain hose through the wall hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slipping hazard.
NOTE: The drainpipe outlet should be at least
5cm (1.9”) above the ground. If it touches the
ground, the unit may become blocked and
malfunction. If you discharge the water directly
into a sewer, make sure that the drain has a U
or S pipe to catch odors that might otherwise
come back into the house.
