Connection of refrigerant piping
Flare processing
1. Cut the pipe using the pipe cutter.
2. Remove burr on the edge of 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. Face the pipe downward when doing the work.
3. Insert the flare nut into the pipe, and then perform the flare processing.
