2.2.3.3 Pipe Bending
(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) If the pipe is repeatedly bent or extended, it will become hard and difficult
to be bent or extended. So do not bend or extend the pipe for more than 3
times.
(4) When bending the pipe, do not bend it excessively, otherwise it will get
broken. As shown beside, use a sharp cutter to cut the heat insulating
pipe and bend it after the pipe is exposed. After bending, place the heat
insulating pipe back on the pipeline and fix it with adhesive tape.
