Packo R22 to R407F Conversion

Converted both these Copeland condensing units to R407F, had to repair a damaged pipe on the condenser on the left hand unit. Changed the oil from mineral to POE oil, and changed the compressor oil level sight glasses, and rotalock gaskets. Am going to change the oil again once it has had some more run time as the oil mineral oil was so dark. These compressors are about 20 years old.
