4.3 Installation of the Connection Pipe
4.3.1 Flare Processing
(1). Cut the connection pipe with the pipe cutter and remove the burrs.
(2). Hold the pipe downward to prevent cuttings from entering the pipe.
(3). Remove the flare nuts at the stop valve of the outdoor unit and inside the accessory bag of
the indoor unit, then insert them to the connection pipe, after that, flare the connection pipe
with a flaring tool.
(4). Check if the flare part is spread evenly and there are no cracks (see Fig.11).
4.3.2 Bending Pipes
(1). The pipes are shaped by your hands. Be careful not to collapse them.
(2). Do not bend the pipes in an angle more than 90°.
(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.13, 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.
