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

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
