Lubricant Adjusting Procedure For Compressor Replacement

LUBRICANT

Lubricant Adjusting Procedure for Compressor Replacement

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





1.Turn the compressor so that it faces downward, and drain the compressor oil from the high-pressure port (A) and low pressure port (B).
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 (2.0 US fl oz., 2.1
Imp fl oz.), perform calculation by setting "D" as 40 m (1.4 US fl oz., 1.4 Imp fl oz.).





Example: Lubricant amount to be drained from a new compressor when replacing compressor and liquid tank [m (US fl oz., Imp fl oz.)] [D = 60 (2.0, 2.1), a = 5 (1.4, 1.4)]
150 (5.1, 5.3) [60 (1.5, 1.6) + 20 (0.7, 0.7) + 15 (0.5, 0.5) + 5 (0.2, 0.2)] = 50 (1.7, 1.8)
3.Install compressor and check the operation.
