SUBCOOL CHARGING CHART CORRECTIONS TABLE

Use Design Subcooling

TOTAL REFRIGERANT LINE LENGTH (FT)

Design Subcooling Value = __________º F

(from nameplate or Service Facts) 

Subcooling Correction = __________º F

Final Subcooling Value = __________º F

STEP 2

 - Determine the final subcooling value using total Line Length and Lift measured in STEP 1 and the charts below.

STEP 3 

- Stabilize the system by operating for a 

minimum of 20 minutes.

At startup, or whenever charge is removed or 
added, the system must be operated for a mini-
mum of 20 minutes to stabilize before accurate
