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 “A”

Shortened as required

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

You must extend the assembly cable.

For further details on how much refrigerant(R410A) should be added, refer to Page 13.

2If 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

3To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer.

4Put a flare nut slightly into the pipe and modify the flare.

Outer Diameter (D)	Depth (A)
1/4 inch (6.35mm)	0.05 inch (1.3mm)
3/8 inch (9.52mm)	0.07 inch (1.8mm)
1/2 inch (12.80mm)	0.08 inch (2.0mm)
5/8 inch (15.88mm)	0.09 inch (2.2mm)

5Check if you flared the pipe correctly (see examples of incorrectly flared pipes below.)
