Anothe night another retrofit. Hill Phoenix medium temp rack with 7 copeland 3ds. Our strategy: Close oil floats to all but one comp and let them pump their oil out through the oil seperator. Close the reservoir outlet and empty the reservoir. Begin emptying each comp and clean/inspect strainers. once the reservoir is empty change the oil filter. Then begin refilling the reservoir with new POE oil. Once a comp is finished being emptied and clean you open it back up and let it fill with new oil before turning it back on. Continue pumping new oil into the reservoir as compressors are finished and come back online. Later we'll clean the seperators. This is the second oil change on this rack - one before and one after the retro. Happy HVAC/Ring everybody.
