Compressor Pump Down
I need to replace a combination pressure (high & low) switch on a compressor.
I realize that the refrigerant must be pumped into the LIQUID RECEIVER and isolated before I open the system.
Q: Do I pump ALL the refrigerant into the liquid receiver (i.e. open the suction service valve)?
Q: Will the compressor trip the high pressure switch if the refrigerant is trapped in the liquid receiver?
Q: What is the procedure to recharge the compressor with refrigerant?
Thanks,
KETTLER
