Cutting/Extending the Piping

INSTALLING THE UNIT

Five metres of piping is supplied with the air

conditioner(Optional). This length can if necessary be:

◆ Extended to a maximum of "L" metres

(refer to page 3 for the "L")

◆ Shortened as required

Make sure that you have the required tools available (pipe cutter,

reamer, flaring tool and pipe holder).

Slide a flare nut on to the pipe and modify the flare.

For further details on how to connect up to the outdoor unit and

purge the circuit, refer to page 20.

Check that the flaring is correct, referring to the illustrations below

for examples of incorrect flaring.

To prevent any gas from leaking out, remove all burrs at the cut

end of the pipe, using a reamer.

If you wish to shorten the piping, cut it using a pipe cutter, taking

care to ensure that the cut edge remains at a 90° angle with the

side of the pipe, and referring to the illustrations below for

examples of edges cut correctly and incorrectly.
