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.

4. The SHC is based on 80°F edb temperature of air entering evaporator
coil. Below 80°F edb, subtract (Corr Factor x CFM) from SHC above
80°F edb, add (Corr Factor x CFM) to SHC Correction Factor = 1.10 x
