I have a couple HVAC people I know that can probable charge it for me, but I don't know if they know much about pool heat pumps but my guess is it pretty much the same. Possible Cause: 1. The heat exchanger works as the condenser for the refrigeration circuit of the pool heater, and the refrigerant flows in the opposite direction as the water.
