Lubricant Adjusting Procedure For Compressor Replacement

LUBRICANT


Lubricant Adjusting Procedure for Compressor Replacement

1. Drain lubricant from removed compressor and measure lubricant amount.





1. Drain lubricant from high-pressure port (A) and low-pressure port (B) while rotating magnet clutch.
2. Measure total amount of lubricant that is drained from removed compressor.





2. Drain lubricant from a new compressor that is calculated according to the following conditions.






CAUTION:
If lubricant amount that is drained from removed compressor is less than 60 m (2.1 Imp fl oz.), perform calculation by setting "D" as 40 ml(1.4 Imp fl oz.).






Example: Lubricant amount to be drained from a new compressor when replacing compressor and liquid tank [ml (Imp fl oz.)] [D = 60 (2.1), alpha = 5 (0.2)]
120 (4.2) - [60 (1.6) + 20 (0.7) + 5 (0.2) + 5 (0.2)] = 30 (1.0)
3. Install compressor and check the operation.
