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 l (2.0 US fl oz, 2.1 Imp fl oz), perform calculation by setting "D" as 40 m l (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), alpha = 5 (0.2, 0.2)]
250 (8.5, 8.8) [60 (2.0, 2.1) + 30 (1.0, 1.1) + 10 (0.3, 0.4) + 5 (0.2, 0.2)] = 145 (5.0, 5.1)

3.Install compressor and check the operation.
