Cutting or Extending the Pipe
A 5-meter pipe is supplied with the air conditioner. (optional)
The length of the pipe can be:
Extended up to 15(
09/12
)/30(
18/24
) meters
Shortened as required
If you need a pipe longer than 5 meters:
You must extend the assembly cable.
1
Make sure that you have 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 (see examples of correctly and
incorrectly cut edges below.)
Oblique
Rough
Burr

To prevent a gas leak, remove all burrs at the cut edge of the pipe using a
reamer.
4
Put a flare nut slightly into the pipe and modify the flare.

Align the pipes to connect them easily. Tighten the flare nuts first with your
hands, and then with a torque wrench, applying the following torque:
