I have a pentair mini max plus hp600 pool heat pump heater. The compressor appears to be locked up. The unit says it is a r410 and the manufacturer agrees. The problem is to replace the compressor with the same compressor model is $1600. Here is the rub, the oem compressor says r22 on the compressor. I think that Pentair used a r22 compressor but used r410 in the system. Does that make sense? Can it be done?

I want to replace the compressor with another r22 = tonage compressor at a fraction of the cost, but I want to make sure I can recharge with r410 once I replace the compressor without causing other issues. I think I just need to drain/replace the oil.

Thanks in advance for your help
