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 m (1.4 Imp fl oz.).





Example: Lubricant amount to be drained from a new compressor when replacing compressor and liquid tank [m (Imp fl oz.)] [D = 60 (2.1), (alpha) = 5 (0.2)]
210 (7.2) [60 (1.6) + 20 (0.7) + 5 (0.2) + 5 (0.2)] = 120 (4.2)
3.Install compressor and check the operation.
