Conventional Line Set Installation: Pipe Bending

1. Use a tubing bender to change pipe direction.
2. If tubing is coiled, extend it by unwinding it from one
end.
3. DO NOT bend the pipe excessively.
MINIMUM BEND RADIUS
When bending refrigerant piping, the minimum bending
radius is 4 inches.

4. Use a sharp cutter to cut the pipe insulation as shown,
and bend the pipe after it is exposed. After bending,
place the insulation back on the pipe and secure it with

Step 1: Cutting
1. When preparing refrigerant pipes, take your time to
cut and flare them properly. This will ensure efficient
operation and minimize the need for future repairs and
loss of comfort.
2. Measure and record the distance between the indoor
and outdoor units.
3. Make sure that the pipe is cut at a perfect 90° angle.
Refer to the image below for guidance.

NOTE:
Be extra careful not to damage, dent, or deform the pipe
while cutting. This will drastically reduce the operating
efficiency of the unit.
