INSTALLATION
Install liquid tank, and then install liquid tank bracket on condenser.
CAUTION:
●
Make sure liquid tank bracket is securely installed at protru-
sion of condenser. (Make sure liquid tank bracket does not
move to a position below center of liquid tank.)
●
Replace O-rings of liquid tank pipe (inside pipe and outside
pipe) with new ones, and then apply compressor oil to it
when installing it.
●
When recharging refrigerant, check for leaks.

INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
●
Replace O-rings of high-pressure pipe 1 and high-pressure flexible hose 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.
