INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing
it.

to deform female-side piping. Slowly insert in axial direction.
Insert one-touch joint connection point securely until it clicks.
After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.
When recharging refrigerant, check for leaks.
