Notes: * The “Charge Amount with SVH Air Handler” column is based on the charge amount for a SVH Air Handler + Com-
pressor Section/Split.
Additional charge will need to be added accordingly for line set length.
After charge is added, additional adjustments can be made to get appropriate subcooling and superheat measurements.
Additional charge for R410A is 0.50 oz. per ft. for 3/8” and 1.0 oz. per ft. for 1/2” tube.
Longer line sets will significantly reduce capacity and efficiency of the system as well as adversely effect the system reli-
ability due to poor oil return.
NOTE: Manufacturer recommends the standard total line set length not to exceed 80 ft with no more than 25 ft of vertical
separation between the compressor section and the air handler. For installations that exceed the standard range refer to the
Long Line Set Application Guide AG2200EW for further installation requirements.

factors: 1) water temperature, 2) return air temperature, and 3) ambient
temperature. When any of the factors are at the minimum or maximum
levels, the other two factors must be at the normal level for proper and
reliable unit operation.

WARNING: Gray area represents antifreeze concentrations greater than 35% by weight and should be
avoided due to the extreme performance penalty they represent.
Antifreeze Correction Example
Antifreeze solution is Propylene Glycol 20% by weight. Determine the corrected heating and cooling performance at 30°F and
90°F respectively as well as pressure drop at 30°F for a 033 operating at 100% capacity.
The corrected cooling capacity at 90°F would be: 30,500 Btu/h x 0.969 = 29,554 Btu/h
The corrected heating capacity at 30°F would be: 34,100 Btu/h x 0.913 = 31,133 Btu/h
The corrected pressure drop at 30°F and 11.5 gpm would be: 7.9 feet of head x 1.270 = 10.03 feet of head
