I feel stupid for asking this question but I just got put on the spot. I have a customer who called at 6 pm and wants a price to change the oil in both compressors because his oil analysis showed border line moisture. Can the oil be changed without pulling the refrigerant charge? I don't think the chiller has the opti to discuss otheronal suction service valve. I tried to discuss other options but he wants the oil changed, period.
Can somebody please help me with any instructions? Surely you don't have to pull the charge. I have to prepare a quote tonight. PLEASE HELP!
