PRODUCT SPECIFICATIONS Fan Coils: FCM4X NOTES: 1. Contact manufacturer for cooling capacities at conditions other than shown in table. 2. Formulas: Leaving db = entering db - sensible heat cap. 1.09 x CFM Leaving wb = wb corresponding to enthalpy of air leaving coil (hlwb) hlwb = hewb - total capacity (Btuh) 4.5 x CFM where hewb = enthalpy of air entering coil. Direct interpolation is permissible. Do not extrapolate. 3. SHC is based on 80_F db temperature of air entering coil.
