INSTALLATION
PROCEDURE
1. ADJUST COMPRESSOR OIL
| (a)
When replacing the compressor with motor assembly with a new one,
gradually discharge the inert gas from the service valve, and drain the
following amount of oil from the new compressor with motor assembly
before installation. Standard: (Oil
capacity inside the new compressor with motor assembly: 120 to 135 cc
(4.06 to 4.56 fl. oz)) - (Remaining oil amount in the removed compressor
with motor assembly) = (Oil amount to be removed from the new
compressor)
NOTICE:
- If a new compressor with motor assembly is installed without removing
some oil, there will be too much oil in the system due to the oil
remaining in the pipes of the vehicle. Excessive oil in the system
prevents heat exchange in the refrigeration cycle and causes ineffective
cooling.
- If the amount of oil remaining in the old compressor with motor assembly
is too small, check the air conditioning system for oil leaks.
- Be sure to use ND-OIL 11 or equivalent compressor oil. If any compressor
oil other than ND-OIL 11 is used, compressor with motor assembly
insulation performance may decrease, resulting in leakage of electric
power.
