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.
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
components.
Step 9:
Connect drain hose
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.
•
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.
Indoor Drainpipe Installation
1. Make sure the drain pipe is connected to the
outdoor side downward.
2.
The hard polyvinyl chloride(PVC)plastic pipe
(external diameter 26 mm) sold in the market
is suitable for the attached soft drain pipe.
3. Please connect the Soft Drain Pipe with the
Drain Pipe, then fix it with band; if you have
to connect the Drain Pipe indoors, to avoid
condensing caused by air intake, you must
cover the pipe with heat-insulation material
(polyethylene with Specific Gravity of 0.03, at
least 9 mm in thickness), and use Glue Band
to fix it.
4. After the Drain Pipe has been connected,
please check if the water drains out of the
pipe efficiently and has no leakage.
5. Refrigerant Pipe and Drain Pipe should be
heat-insulated to avoid condensing and
water-dropping later on.
6. 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.

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 from your dealer.

Outdoor Unit Installation
Installation Instructions – Outdoor unit
Step 1: Select installation location
Before installing the outdoor unit, you must
choose an appropriate location. The following are
standards that will help you choose an appropriate
location for the unit.
Proper installation locations meet the
following standards:
o
Meets all spatial requirements shown in
Installation Space Requirements above.
o
Good air circulation and ventilation
o
Firm and solid—the location can support the
unit and will not vibrate
o
Noise from the unit will not disturb others
Install the unit by following local codes and
regulations , there may be differ slightly
between different regions.
SPECIAL CONSIDERATIONS FOR
EXTREME WEATHER
If the unit is exposed to heavy wind:
Install unit so that air outlet fan is at a 90°
angle to the direction of the wind. If
needed, build a barrier in front of the unit
to protect it from extremely heavy winds.
See Figures below .
Strong
wind
Strong wind
If the unit is frequently exposed to
heavy rain or snow:
Build a shelter above the unit to protect
it from the rain or snow. Be careful not to
obstruct air flow around the unit.
If the unit is frequently exposed to
salty air (seaside):
Use outdoor unit that is specially designed
to resist corrosion.
Strong wind
Wind Baffle
o
Protected from prolonged periods of direct
sunlight or rain
DO NOT
install unit in the following locations:
Near an obstacle that will block air inlets
and outlets
Near a public street, crowded areas, or
where noise from the unit will disturb others
Near animals or plants that will be harmed
by hot air discharge
Near any source of combustible gas
In a location that is exposed to large
amounts of dust
In a location exposed to a excessive amounts
of salty air
o
Where snowfall is anticipated, raise the
unit above the base pad to prevent ice
buildup and coil damage. Mount the unit
high enough to be above the average
accumulated area snowfall. The minimum
height must be 18 inches
