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
