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 SHC is based on 80°F Edb (Entering dry bulb) air temperature

through Evaporator coil. Below 80°F Edb, subtract (Correction Factor x
CFM) from SHC. Above 80°F Edb, add (Correction Factor x CFM) to
SHC. Correction Factor = 1.10 x (1 + BF) x (Edb + 8)
