NOTES:
1 Direct Interpolation is pelmissible Do not
extra polate
2 Tlie following formulas may be used:
sensible capacity (Btuh)
t|db -tedb 1 09 X cfm
t|wb Wet-bulb temperature corresponding to en
thalpy of air leaving evaporator coil (h|yy[j).
^ ^ total capacity (Btuh)
Iwb - ewb 4 5 X cfm
Where
hewb “ Enthalpy of air entering evaporator coil
3 SFIC is based on 80 F edb temp of air ent evap coil
Below 80 F edb, subtract (corr factor x cfm) from
SHC.
Above so F edb, add (corr factor x cfm) to SHC.

NOTE Ratings are based on 70 F air entering indoor coil without
resistance heaters Integrated capacity is maximum (instarrtaneous)
capacity less the effect of frost on the outdoor coil and the heat re
quired to defrost it Ratings are at 2 in wg ESP for cfm indicated for
006 units, at 25 in wg for 008 units and, Sin wg for 010 rrnits
