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 (40-59”).
•
If the outlet of the drainpipe is higher than
the body’s pump joint, provide a lift pipe for
the exhaust outlet of the indoor unit. The
lift pipe must be installed no higher than
75cm (29.5”) from the ceiling board and
the distance between the unit and the lift
pipe must be less than 30cm (11.8”).
Incorrect installation could cause water to
flow back into the unit and flood.
•
To prevent air bubbles, keep the drain hose
level or slightly tiled up (<75mm / 3”).
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,
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
Install the drainpipe as shown in Fig 5.2.
1. Cover the drainpipe with heat insulation to

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

Refrigerant Piping Connection Instructions
CAUTION
• The branching pipe must be installed
horizontally. An angle of more 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
care to cut and flare them properly. This will
ensure efficient operation and minimize the
need for future maintenance.
For R32/R290
refrigerantmodels, the pipe connection
points must be placed outside of room.
The connection pipes can not be reused.
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.
CAUTION
DO NOT deform pipe while cutting. Be extra
careful not to damage, dent, or deform the
pipe while cutting. This will drastically reduce
the heating efficiency of the unit.
1. Make sure that the pipe is cut at a perfect
90° angle. Refer to Fig. 6.3 for examples of
bad cuts.

CAUTION
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. (See Fig. 6.2)
The outdoor unit is installed higher than the indoor unit
6. Place flaring tool onto the form.
7. Turn the handle of the flaring tool
clockwise until the pipe is fully flared. Flare
the pipe in accordance with the dimensions
shown in table 6.3.
Table 6.3: PIPING EXTENSION BEYOND FLARE
FORM
8. Remove the flaring tool and flare form,
then inspect the end of the pipe for cracks
and even flaring.
Step 4: Connect pipes
Connect the copper pipes to the indoor unit first,
then connect it to the outdoor unit. You should
first connect the low-pressure pipe, then the
high-pressure pipe.
1. When connecting the flare nuts, apply a
thin coat of refrigeration oil to the flared
ends of the pipes.
2. Align the center of the two pipes that you
will connect.

Note On Adding Refrigerant
CAUTION
• Refrigerant charging must be performed after wiring, vacuuming and the leak test.
• DO NOT exceed the maximum allowable quantity of refrigerant or overcharge the system.
Doing so can damage or impact the unit’s function.
• Charging with unsuitable substances may cause explosions or accidents. Ensure that the
appropriate refrigerant is used.
• Refrigerant containers must be opened slowly. Always use protective gear when charging
the system.
• For the R290 or R32 refrigerant model, make sure the condtions within the area have been
made safe by control of ammable material when the refrigerant added into air conditioner.
• DO NOT mix refrigerants types.
Some systems require additional charging depending on pipe lengths. The standard pipe length
varies according to local regulations. For example, in North America, the standard pipe length is
7.5m (25’) In other areas, the standard pipe length is 5m (16‘). The additional refrigerant to be
charged can be calculated using the following formula:
