Performance Data

Fixed Orifice Superheat Charging Table

Use a digital psychrometer to measure return air wet-bulb temperature and outdoor dry-bulb temperature to locate the target superheat. Do not attempt to charge the system if conditions fall outside this table. Add refrigerant to decrease superheat; remove refrigerant to increase superheat. Allow 10-15 minutes after changes for stabilization.
