Note on Pipe Length

Ensure that the length of the refrigerant pipe, the number of bends, and the drop height
between the indoor and outdoor units meets the requirements shown in the following table :

Bends: no more than 5 places. A minimum pipe run of 3 metres is required to minimise vibration &
excessive noise.

Refrigerant Piping
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.
Hold the pipe at a downward angle to prevent
1.
burrs from falling into the pipe.
Using a reamer or deburring tool, remove all
2.
burrs from the cut section of the pipe.
