3.2.2.3 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.
3.2.2.4 Connection Pipe Of The Units
①
. Connect the pipe to the unit. Please follow the instructions stated in the figures
below. Use both spanner and torque wrench.
②
. When connecting the tapered screw nut, first apply chilled machine oil on its
inner and outer surface and then screw it up for 3~4 circles.
③
. Confirm the tightening torque by referring to the following table (If the screw
nut is over-twisted, it may be damaged and cause leakage).
④
. Check whether gas leakage occurs to the connection pipe and then apply
thermal insulation, as shown below.
⑤
. Wind sponge around the joint of gas pipe and heat insulation sheath of gas
collecting pipe.
⑥
. Be sure to connect gas pipe after liquid pipe is connected.
