8. Charging Compressor Oil
8-3. Charging Additional Compressor Oil (after replacing compressor)
The rated amount of oil is pre-charged in the compressors as given below:
When replacing a faulty compressor, be sure to first measure the amount of remaining oil in the compressor.
Charge additional new oil equal to the difference in the remaining oil and the rated amount as listed above.
For example: Type of replaced compressor: JT170G-KTYE
Remaining oil in the removed compressor: 2.2
Additional oil to be charged: 2.2 (remaining oil in the removed compressor) – 2.1 (rated oil amount) = 0.1
* If the result is a negative amount (remaining oil in the removed compressor is less than the rated amount), it is
not necessary to discharge the extra oil from the system.
For the method used for additional oil charging after compressor replacement, refer to “8-1. If Refrigerant Has
Already Been Charged to Outdoor Unit.”
