Installing the Air conditioner

Cutting or Extending the Pipe

A 24.6ft(7.5m) pipe is supplied with the air conditioner. (Optional)

The length of the pipe can be:

◆ Extended up to 98.4ft(30m)

◆ Shortened as required

☛ If you need a pipe longer than 24.6ft(7.5m):

◆ You must extend the assembly cable.

◆ You must add refrigerant to the pipes;

otherwise, the indoor unit may freeze.

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.

Oblique Rough Burr

3 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.
