Caution for flare
connections
Refer to below table for correct flare dimensions and tightening torques. Too high tightening
force may cause refrigerant leak because of flare cracking:
When connecting the flare nut, apply refrigerating machine oil to the flare (inside and
outside) and first screw the nut 3 or 4 turns by hand. Coat the indicated surfaces using ether
or ester oil:
After completing the installation, carry out an inspection of the piping connections by
pressure test using nitrogen.
