2. No additional refrigerant oil charge is required if:
remaining refrigerant oil quantity in the old compressor < pre-charged refrigerant oil in the new compressor
3. The recharged quantity of the refrigerant oil to the cycle is calculated as follows:
(Remaining quantity in the old compressor + Collected quantity in the item 2.10 (10) + 0.53 gal*) -
(Initial charged quantity in the compressor for each model)
Compressor Initial Charged Refrigerant Oil
For Inverter (ANB52FZNMT) 0.61 gal
For Inverter (ANB66FZNMT) 0.61 gal
