(1). Align the ared end of the copper tube with the threaded connector, and then hand-tighten
the ared nut.
(2). Further tighten the ared nut with a torque wrench until the torque wrench sounds a “crack”.
(3). The bending of the pipe shall not be too small, otherwise the pipe may crack. A pipe bender
must be used when bending the pipe.
(4). Wrap the thermally untreated pipe and connectors with sponge and then tighten the sponge
with plastic tape.
Notes:
① .
During the piping, do not pull any connector forcefully to prevent the capillary and other
pipes from cracking, which then would result in leakage.
② .
The pipe should be properly supported in the way that its weight will not be borne by the
unit.
If the specication of the outdoor unit pipe joint does not conform to that of the indoor unit, then
the joint specication of the outlet pipe of the indoor unit takes precedence. A reducing nipple shall
be installed at the joint of the outdoor unit so as to make the joint of the outdoor unit compatible
with that of the indoor unit.
