(3). 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.
(4). 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. 4.10,
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!
①
. To prevent breaking of the pipe, avoid sharp bends. Bend the pipe with a radius of curvature of 150
mm or over.
②
. If the pipe is bent repeatedly at the same place, it will break.
4.3.3 Connecting the Pipe at the Indoor Unit Side
CAUTION!
①
. Be sure to apply the pipe against the port on the 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.
②
. Do not remove the flare nut until the connection pipe is to be connected so as to prevent dust and
impurities from coming into the pipe system.
(1). Detach the caps and plugs from the pipes.
(2). Align the center of the piping flare with the pyramidal face of relevant valve.
(3). Screw in the flare nut by hand and then tighten the nut with spanner and
torque wrench refer to the following.
