Cutting Or Flaring The Pipes - Samsung RD VHXF Series Installation Manual

Cutting or Flaring the pipes

To prevent foreign materials or water from entering the pipe, it is important to keep the refrigerant pipe clean
and dry and to seal it while installing.
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.
4. Carry out flaring work using flaring tool as shown below.
