BF—BypassFactor
edb— Entering Dry---Bulb
Ewb— Entering Wet---Bulb
kW— Total Unit PowerInput
SHC— Sensible HeatCa pacity (1000 Btuh)
TC — Total Capacity (1000 Btuh) (n et)
rh—Relative Humidity
COOLING NOTES:
1.Ratingsarenet; they accountfor theeffectsof the evaporator---fan motorpower andheat.
2. Direct interpolationispermissible. Donot extrapolate.

4. The SHC isbased on 805F (26.6_C)edb temperature of air enteringevaporator coil. Below80_F (26.6_C) edb, subtract (corr factor x cfm) from SHC.
Above 80_F (26.6_C) edb, add (corr factor x cfm) to SHC.
Correction Factor = 1.10x (1 + BF) x (edb+ 80).
5. Integrated capacity is maximum (instantaneous) capacity less the effect of frost on the outdoor coil andthe heat required to defrost it.
