Connection Instructions –
Refrigerant Piping
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.
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.
2. Using a pipe cutter, cut the pipe a little longer
than the measured distance.
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 e ciency
of the unit.

Step 2: Remove burrs.
Burrs can a ect 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.

Step 3: Flare pipe ends
Proper aring 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 are 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.

4. Remove PVC tape from ends of pipe when
ready to perform aring work.
5. Clamp are form on the end of the pipe.
The end of the pipe must extend beyond
the are form.
