A.5: Testing Undercharge Or Overcharge Of Refrigerant
Unlike normal refrigerating or air conditioning systems, the QUANTUM heat pump operates under a very wide range of evaporating and condensing
temperatures. To identify undercharge or overcharge of refrigerant gas in the system, three parameters need to be checked.
1. Current Draw
2. System Pressures
3. Bubbles through sight glass on the receiver / filter-dryer
