NOTES:
* The "Charge Amount with YAH Air Handler" column is based on the charge amount for a YAH Air Compressor Section/Split.
Additional charge will have to be added accordingly for line set length.
After Charge is added adjustments can be made to get appropriate subcooling and superheat.
Additional charge for R-410A is 0.50 oz. per ft. for 3/8 in. and 1.0 oz. per ft. for 1/2 in. tube.

Determining Subcooling
1.
Measure the temperature of the liquid line on the small
refrigerant line (liquid line) just outside the split cabinet. This
location will be adequate for measurement in both modes unless
a significant temperature drop in the liquid line is anticipated.
2.
Measure the liquid line pressure by attaching refrigerant
gauges to the Schrader connection on the liquid line
service valve.
3.
Convert the pressure obtained in Step 2 to the saturation
temperature by using the R-410A Pressure/Temperature
Conversion Chart.
4.
Subtract the temperature in Step 1 from the temperature in
Step 3. The difference will be the subcooling value for that
unit. Refer to the Operating Parameters tables for subcooling
ranges at specific enter water conditions.
