pressure gauges on the gauge ports of the discharge and suction line valves. Check the suction and discharge
pressures and compare them to the normal operating pressures provided in the unit's Service Facts.
NOTE:
Use the pressures from Service Facts to determine the unit refrigerant charge.
To charge the system accurately, use superheat charging, or pressures
depending on flow control.
