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.

Where: ewb = Enthalpy of air entering evaporator coil
4. The SHC is based on 805 F (26.6_C) edb temperature of air entering evapo-
rator coil. Below 805 F (26.6_C) edb, subtract (corr factor x cfm) from SHC.
Above 805 F (26.6_C) edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10 x (1 + BF) x (edb + 80).
5. Integrated capacity is maximum (instantaneous) capacity less the effect of
frost on the outdoor coil and the heat required to defrost it.
