CONNECTING THE PIPING

1. FLARE PROCESSING

(1)

Cut the connection pipe with pipe cutters so that the pipe is
not deformed.

(2)

Holding the pipe downward so that cuttings cannot enter the
pipe and remove the burrs.

(3)

Remove the flare nut from the indoor unit pipe and outdoor
unit and assemble as shown in (Table 3) and insert the flare
nut onto the pipe, and flare with a flaring tool.

(4)

Check if the flared part “L” (Fig. 20) is spread uniformly and
that there are no cracks.

Table 3

Pipe

Small pipe

Large pipe

Fig. 20

Small (width across flats 17 mm)

Large (width across flats 24 mm)

2. BENDING PIPES

The pipes are shaped by your hands. Be careful not to collapse them.

Fig. 21

Do not bend the pipes in an angle more than 90°.
When pipes are repeatedly bent or stretched, the material will
harden, making it difficult to bend or stretch them any more. Do
not bend or stretch the pipes more than three times.

When bending the pipe, do not bend
it as is. The pipe will be collapsed. In
this case, cut the heat insulating pipe
with a sharp cutter as shown in Fig.
22, and bend it after exposing the
pipe. After bending the pipe as you
want, be sure to put the heat insulat­ing pipe back on the pipe, and secure
it with tape.

CAUTION

To prevent breaking of the pipe, avoid sharp bends.

1

Bend the pipe with a radius of curvature of 150 mm
or over.

If the pipe is bent repeatedly at the same place, it will

2

break.

CAUTION

Be sure to apply the pipe against the port on the

1

indoor unit correctly. If the centering is improper, the
flare nut cannot be tightened smoothly. If the flare
nut is forced to turn, the threads will be damaged.

Do not remove the flare nut from the indoor unit pipe

2

until immediately before connecting the connection
pipe.

Centering the pipe against port on the indoor unit, turn the flare

•

nut with your hand.
When the flare nut is tightened properly by your hand, hold the
body side coupling with a separate spanner, than tighten with a
torque wrench (Fig. 23).
