REFRIGERANT LINE

PROCEDURE

INSTALL PIPING CLAMP

Remove the vinyl tape from the cooler refrigerant liquid pipe A and liquid tube sub-assembly A.
Sufficiently apply compressor oil to 2 new O-rings and the fitting surfaces of the cooler refrigerant liquid pipe A.

Compressor Oil

ND-OIL 11 or equivalent

Note:
Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in leakage of electric power.
Install the 2 O-rings to the liquid tube sub-assembly A.

Note:
Keep the O-rings and O-ring fitting surfaces free of foreign matter.
Install the cooler refrigerant liquid pipe A to the liquid tube sub-assembly A.
Note:
- Make sure not to cut the O-ring while installing it. (Cut O-rings cannot be installed)
- Check that the assemblies are securely engaged.

Compressor Oil
ND-OIL 11 or equivalent

Install the piping clamp to the cooler refrigerant liquid pipe A and liquid tube sub-assembly A.

Note:

Make sure that the piping clamp is engaged securely with no gap.
