Purging the indoor unit
1. Make sure that you have all the required tools (pipe cutter, reamer, aring 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 (see below examples of correct and incorrect cut edges).
3. To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer.
4. Put a are nut slightly into the pipe and modify the are.
