INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings with new ones. Then apply compressor oil to them when installing.
- Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping straight in axial direction.
- Insert piping securely until a click is heard.
- After piping connection is completed, pull male-side piping by hand to check that connection does not come loose.
- Check for leakages when recharging refrigerant.
