Need your help again, I have this FreezeCo chiller faulting out on "Compressor High Pressure" alarm.
Refrigerant : R22
Compressor : 1
Application : Cooling process coolant
Condensor : Very clean, no blockage to air flow
It has In built High Pressure gauge showing 230 PSI, Low pressure gauge showing 45 PSI. When I connect my gauges it shows 330 PSI and 145 PSI. Also it faults out at the end of the cycle when thermostat is satisfied and compressor is about to turn off. In built High pressure gauge needle will start shaking, unit will fault out and compressor stops. Can not read model number or serial number on the unit.
Any help will be greatly appreciated.
