Installing the Refrigerant Pipe Work (Continued)
Cutting or Flaring the Pipes
1
Make sure that you prepared the required tools. (pipe cutter, reamer, flaring
tool and pipe holder)
2
If you want to shorten the pipe, cut it using a pipe cutter ensuring that the
cut edge remains at 90° with the side of the pipe. There are some
examples of correctly and incorrectly cut edges below.
3 To prevent a gas leak, remove all burrs at the cut edge of the pipe using a
reamer.

Carry out flaring work using flaring tool as shown below.
