Hi all,
I have a Trane Chiller with model number: RTHB 450. Could someone please inform me on proper pumpdown sequence of this chiller? It has a condenser isolation valve after the condenser. This would still be part of the liquid line, if I am not mistaken. Could that be used to pumpdown? Could someone give me the correct procedure in doing this step by step.
Regards,
