COMPRESSOR(for 1AD-FTV)

INSPECT COMPRESSOR OIL

When replacing the compressor assembly with a new one, gradually discharge the inert gas (helium) from the service valve, and drain the following amount of oil before installation.

Standard
(The amount of compressor oil inside a new compressor assembly with pulley: 90 (+15) cc (3.04 (+0.507) fl.oz.)) - (The amount of compressor oil remaining in the removed compressor assembly with pulley) = The amount of compressor oil to be removed when replacing the compressor assembly with pulley

Note

If a new compressor assembly with pulley is installed without removing the same amount of compressor oil as is remaining in the pipes, the amount of compressor oil will be excessive. This prevents heat exchange in the refrigerant cycle and will cause a refrigeration failure.
If the amount of compressor oil remaining in the removed compressor assembly with pulley is too low, check for compressor oil leakage.
Make sure to use ND-OIL 8 or equivalent compressor oil.

Remove the suction seal cap.
Position the suction port downward and slightly shake the compressor to drain the oil. (*1)

Note

Be careful not to allow compressor oil to adhere on the pulley.
Position the DL pulley side downward and turn the pulley in the direction indicated by the arrow once in every 2 seconds 10 times. (*2)

Note

Keep your face away from the compressor port because turning the pulley may cause gas or oil to spray out.
Quickly position the DL pulley side upward and turn the pulley in the direction indicated by the arrow once. (*3)
Repeat procedure (*1). (*4)
Repeat procedures (*2) through (*4) about 5 times to drain the standard amount of oil.
