4- Refer to the required Subcooling in the table based on the model size and
the Outdoor Ambient temperature.
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.
9 - Remove charge if the measured temperature is lower than the table value.

6- Find the Pressure Value in the table corresponding to the the measured
Pressure of the Compressor Discharge line.
8- Add Charge if the measured temperature is higher than the table value.
7- Read across from the Pressure reading to obtain the Liquid line
temperature for a required Subcooling
Charging Procedure
5- Interpolate if the Outdoor ambient temperature lies in between the table
values.
