Installation [08/2020 - ]: Procedure

1. When replacing the cooler compressor assembly with a new one, gradually discharge the refrigerant gas from the service valve, and then drain the following amount of oil from the new cooler compressor assembly before installation.

   Standard

   (Oil capacity inside the new cooler compressor: 135 + 15 cc (4.57 + 0.51 fl.oz.)) - (Remaining oil amount in the removed compressor and magnetic clutch) = (Oil amount to be removed from the new compressor when replacing)

   NOTE:

   • When checking the compressor oil level, follow the A/C system precautions.
   • If a new cooler 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 the air conditioning system to malfunction.
   • A certain amount of compressor oil remains in the cooler compressor assembly with pulley during circulation and the cooler compressor assembly may be damaged if the amount of compressor oil is more/less than this amount. Therefore, make sure to adjust the amount of compressor oil correctly.
   • If the amount of compressor oil remaining in the removed cooler compressor assembly with pulley is excessively low, check for compressor oil leaks.
   • Make sure to use ND-OIL 12 or equivalent compressor oil.

1. Install the stud bolt.
