suitable material such as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
• Replace O-rings of high-pressure pipe 1 and 2 with new ones, and then apply compressor oil to it
when installing it.
• 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 make sure that connection
does not come loose.
• When recharging refrigerant, check for leaks.
