STEP 4

 - Measure the liquid line temperature 

and pressure at the outdoor unit’s service valve.

Measured Liquid Line Temp = __________  º F

Liquid Gage Pressure = __________ PSI

Final Subcooling Value = __________  º F

STEP 5

 - Use the final subcooling value, refriger-

ant temperature and pressure from STEP 4, to 
determine the proper liquid gage pressure using 
Table 14.2.

  Example: Assume a 12º F Final Subcooling 

value and liquid temp of 90º F.  

    1. Locate 12º F Final Subcooling in Table 14.2.
    2. Locate the Liquid Temperarature (90º F) in 

the left column.

    3. The Liquid Gage Pressure should be ap-

proximately 327 PSI.  (This is the shown as 
the intersection of the Final Subcooling column 
and the Liquid Temperature row.
