Connecting pipes
2. Bend the connection pipe to an appropriate length using a bender depending upon the installation place.
3. Perform pipe bending process.
- Perform bending of the pipe using the pipe bender which has a specified bending radius.
- Be sure to take full care to perform bending of the pipe successfully at one time. Bending and unbending the pipe more
than twice makes the bending work increasingly difficult.
4. Connect the high pressure pipe (ø6.35 mm) and low pressure pipe (ø15.88 mm) to the high/low pressure pipe of the
outdoor unit and tightening by applying appropriate torque.

Flare process
1) Cut the pipe using the pipe cutter.

2) Remove burr on the edge of the pipe.
•
If burr is not removed after cutting the pipe, there is a risk of refrigerant
gas leakage.
•
If foreign substance such as burr goes into the pipe, there is a risk of
product breakdown. Therefore, face the pipe downward when doing
the work.

3) Insert the flare nut into the pipe, and then perform the flare process.
