5 metres(16ft. 5in) of piping is supplied with the air
conditioner(Optional). This length can if necessary be:
◆
Extended to a maximum of 15m(49ft. 3in)
◆
Shortened as required
☛
If more than 5m(16ft. 5in) of piping is required:
◆
The assembly cable must also be extended
◆
Refrigerant must be added to the circuit by an
approved installer; otherwise, the indoor unit may
freeze
1 Make sure that you have the required tools available
(pipe cutter, reamer, flaring tool and pipe holder).
2 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.
Oblique Rough Burr
3 To prevent any gas from leaking out, remove all burrs at the cut end of the
pipe, using a reamer.
4 Slide a flare nut on to the pipe and modify the flare.
Pipe Outer Diameter (D) Depth (A)
Liquid refrigerant 6.35 mm(1/4˝) 1.3 mm(1/16˝)
Gas refrigerant 9.52 mm(3/8˝) 1.8 mm(1/16˝)
Gas refrigerant 12.70 mm(1/2˝) 2.0 mm(1/16˝)
5 Check that the flaring is correct, referring to the illustrations below for
examples of incorrect flaring.
Inclined Damaged Surface Cracked Uneven Thickness
6 Align the pipes to be connected and tighten the flare nuts first manually
and then with a wrench, applying the following torque.
7 For further details on how to connect up to the outdoor unit and purge the
circuit, refer to page 45.
