} Sensible capacities shown are based on 80 F (27 C) entering air at the indoor coil. For sensible capacities at other than 80 F (27 C), deduct 835 Btuh (245 kW) per 1000 CFM (480 L/S) of indoor coil air for each degree below 80 F (27 C), or add 835 Btuh

BF— Bypass Factor
edb— Entering Dry---Bulb

TC — Total Capacity (1000 Btuh) (net)
rh—Relative Humidity
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 SHC is based on 80_F (26.6_C) edb temperature of air enteringevaporator coil. Below 80_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 = 1.10 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.
