Safety Precautions
WARNING
• Securely install the indoor unit on a
structure that can sustain its weight. If the
structure is too weak, the unit may fall and
cause personal injury, unit and property
damage, or death.
• DO NOT install the indoor unit in a
bathroom or laundry room as excessive
moisture can short the unit and corrode the
wiring.
CAUTION
• Install the indoor and outdoor units, cables,
and wires at least 1m (3.2’) from televisions
and radios to prevent static or image
distortion. Depending on the appliances,
a 1m (3.2’) distance may not be sucient.
• If the indoor unit is installed on metal,
it must be electrically grounded.

Outdoor Unit Installation Instructions
Step 1: Select installation location.
The outdoor unit should be installed in the
location that meets the following requirements:
Place the outdoor unit as close to the indoor
unit as possible.
Ensure that there is enough room for
installation and maintenance.
The air inlet and outlet must not be
obstructed or exposed to strong wind.
Ensure the location of the unit will not be
subject to snowdrifts, accumulation of leaves
or other seasonal debris. If possible, provide an
canopy for the unit. Ensure that the canopy
does not obstruct the airflow.
The installation area must be dry and well
ventilated.
There must be enough room to install the
connecting pipes and cables and to access
them for maintenance.
The area must be free of combustible gases
and chemicals.
The pipe length between the outdoor and
indoor unit may not exceed the maximum
allowable pipe length.
If possible, DO NOT install the unit where it
is exposed to direct sunlight.
If possible, make sure the unit is located far
away from your neighbors’ property so that
the noise from the unit will not disturb them.
If the location is exposed to strong winds (for
example: near a seaside), the unit must be
placed against the wall to shelter it from the
wind. If necessary, use an windbreaks (or similar)
(See Fig. 5.1 & 5.2)
Install the indoor and outdoor units, cables
and wires at least 1 meter from televisions or
radios to prevent static or image distortion.
Depending on the radio waves, a 1 meter
distance may not be enough to eliminate all
interference.

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.

If the drain joint comes with a rubber seal
(see Fig. 5.9 - 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. 5.9 - B ), do the9ollowing:
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 included)
to the drain joint to redirect water from the
unit during heating mode.
16

NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe, tighten
the indoor connection with an additional
protection tube to prevent 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”).
• Incorrect installation could cause water to
flow back into the unit and flood it.
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
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.

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. 6.4). 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.

NOTE: When drilling the hole in the wall, make
sure to avoid wires, plumbing, and other

4. Pass the drain hose through the hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slippage.
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 prevent unwanted odors from
entering the house.
18

Safety Precautions
WARNING
• All eld piping must be completed by a
licensed technician and must comply with
the local and national regulations.
• When the air conditioner is installed in a
small room, measures must be taken to
prevent the refrigerant concentration in
the room from exceeding the safety limit
in the event of refrigerant leakage. If the
refrigerant leaks and its concentration
exceeds its proper limit, hazards due to
lack of oxygen may result.
• When installing the refrigeration system,
ensure that air, dust, moisture or foreign
substances do not enter the refrigerant
circuit. Contamination in the system may
cause poor operating capacity, high
pressure in the refrigeration cycle,
explosion or injury.
• Ventilate the area immediately if there is
refrigerant leakage during the installation.
Leaked refrigerant gas is both toxic and
flammable. Ensure there is no refrigerant
leakage after completing the installation
work.
Notes On Pipe Length and Elevation
Ensure that the length of the refrigerant pipe, the
number of bends, and the drop height between
the indoor and outdoor units meets the
requirements shown in Table 7.1:

Oil traps
CAUTION
•
If the indoor unit is installed higher than the
outdoor unit:
An oil trap should be installed every 10m
(32.8ft) of vertical suction line riser.
(See Fig. 7.2)
-If oil flows back into the outdoor unit’s
compressor, this might cause liquid
compression or deterioration of oil return.
Oil traps in the rising gas piping can prevent
this.
CAUTION
The indoor unit is installed higher than the
outdoor unit
If the outdoor unit is installed higher than the
indoor unit:
-It is recommended that vertical suction risers
not be upsized. Proper oil return to the
compressor should be maintained with suction
gas velocity. If velocities drop below7.62m/s
(1500fpm (feet per minute)), oil return will be
decreased. An oil trap should be installed every
6m(20ft) of vertical suction line riser.
