When bending connective refrigerant piping, the minimum
bending radius is 10cm. See Fig 5.6
Do not use excessive torque
Excessive force can break the nut or damage the refrigerant piping.
You must not exceed torque requirements shown in the table
above.
Align the center of the two pipes that you will connect. See Fig.
5.7 .
Tighten the flare nut as tightly as possible by hand.
Using a spanner, grip the nut on the unit tubing.
While firmly gripping the nut on the unit tubing, use a torque
wrench to tighten the flare nut according to the torque values
in the Torque Requirements table below. Loosen the flaring nut
slightly, then tighten again.
Step 4: Connect pipes
When connecting refrigerant pipes, be careful not to use
excessive torque or to deform the piping in any way. You
should first connect the low-pressure pipe, then the high-
pressure pipe.
