3.
Make sure that the pipe is cut at a perfect 90°
angle.
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.
7.6.2 - Step 2: Remove burrs
Burrs can affect 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.
7.6.3 - Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
1. After removing burrs from cut pipe, seal the ends
with PVC tape to prevent foreign materials from
entering the pipe.
2. Sheath the pipe with insulating material.
3. Place flare nuts on both ends of pipe. Make sure
they are facing in the right direction, because you
can’t put them on or change their direction after
flaring.

When connecting refrigerant piping,
do not
let substances or gases other than the specified
refrigerant enter the unit. The presence of other
gases or substances will lower the unit’s capacity,
and can cause abnormally high pressure in the
refrigeration cycle. This can cause explosion and
injury.
Step 1: 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.
1. Measure the distance between the indoor
and outdoor units.
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.

Using a pipe cutter, cut the pipe a little longer
than the measured distance.

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.

3. Tighten the flare nut as tightly as possible
by hand.
4. Using a spanner, grip the nut on the unit
tubing.
5. While firmly gripping the nut, use a torque
wrench to tighten the flare nut according to
the torque values in above table.
NOTE:
Use both a spanner and a torque
wrench when connecting or disconnecting
pipes to/from the unit.
CAUTION
•
Ensure to wrap insulation around the piping.
Direct contact with the bare piping may
result in burns or frostbite.
•
Make sure the pipe is properly connected.
Over tightening may damage the bell
mouth and under tightening may lead to
leakage.
