COOLING NOTES: 1. Ratings are net; they account for the effects of the evaporator---fan motor power and heat. 2. Direct interpolation is permissible. Do not extrapolate. 3. The following formulas may be used:

4. The S HC is based on 80_F (26.7_C) edb temperature of air en tering evaporator coil. Below 80_F (26.7_C) edb, subtract (corr factor x CFM) from SHC.
Above 80_F (26.7_C) edb, add (corr factor x CFM) to SHC.
Correction Factor = 1.10 x (1 --- BF) x (edb --- 80) .
