Drainpipe Installation
The drainpipe is used to drain water 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.
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 from your dealer.
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.
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.
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.

6. 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 1cm (0.4”).
This will ensure proper water drainage
(See Fig. 6.2). 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.

NOTE: When drilling the wall hole, make
sure to avoid wires, plumbing, and other
sensitive components.
7. 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.

Refrigerant Piping Connection
Safety Precautions
• All field 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. Ensu re there is no refrigerant
leakage after completing the installation
work.
Refrigerant Piping Connection Instructions
•
The branching pipe must be installed
horizontally. An angle of mor
e than 10°
may cause malfunction.
•
DO NOT
install the connecting pipe until
both indoor and outdoor units have been
installed.
•
Insulate both the gas and liquid piping to
prevent water leakage.
Step1: Cut pipes
When preparing refrigerant pipes, take extra
car
e to cut and flare them p roperly. This will
ensur e efficient operation and minimize the
need for future maintenance.
1. Measure the distance between
the indoor and outdoor units.
2. Using a pipe cutter, cut the pipe a little
longer than the measured distance.
DO NOT deform pipe while cutting.
Be extra ca reful not to damage, dent,
or deform the pipe while cutting. This will
drastically r
educe the heating efficiency
of the unit.
1. Make sur e that the pipe is cut at a perfect 90°
angle. Refer to Fig. 7.1 for examples of bad cuts

Step 2: Remove burrs.
Burrs can a ffect the air-tight seal of refrigerant
piping connection. They must be completely
removed.
1. Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool, remove
all burrs from the cut section of the pipe.
