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 (2.0 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 [ml (US fl oz., Imp fl oz.)] [D = 60 (2.0, 2.1), alpha = 5 (0.2, 0.2)]
120 (4.1, 4.2) [60 (1.5, 1.6) + 20 (0.7, 0.7) + 5 (0.2, 0.2) + 5 (0.2, 0.2)] = 30 (1.0, 1.0)
3.Install compressor and check the operation.
