Required Liquid Line Temperature for a Specific Subcooling (R-410A)

1- Measure Discharge line pressure by attaching a gauge to the service port 
2- Measure the Liquid line temperature by attaching a temperature sensing device to it 
3- Insulate the temperature sensing device so that the Outdoor Ambient doesn’t affect the reading
4- Refer to the required Subcooling in the table based on the model size and the Outdoor Ambient 
temperature
5- Interpolate if the Outdoor temperature lies in between the table values. Extrapolate if the 
temperature lies beyond the table range
6- Find the Pressure Value corresponding to the the measured Pressure on the Compressor 
Discharge line 
7- Read across from the Pressure reading to obtain the Liquid line temperature for a required 
Subcooling
8- Add Charge if the measured temperature is higher than the liquid line temperature value in the 
table
9- Add Charge using the service connection on the Suction line of the Compressor
