3. SHC is based on 80°F (27°C) db temperature of air entering the evaporator coil.
Below 80°F (27°C) db, subtract (Correction Factor x CFM) from SHC.
Above 80°F (27°C) db, add (Correction Factor x CFM) to SHC.
4. Direct interpolation is permissible. Do not extrapolate.
5. Fan motor heat has not been deducted.
6. All data points are based on 10°F (−12°C) superheat leaving coil and use of thermostatic expansion valve (TXV) device.
7. The ENH4X coils can be used in any properly designed system using R−410A refrigerant.
8. Before using maximum cfm shown in table, check coil static pressure drop to ensure system blower can provide necessary
static pressure needed for coil and duct systems.
9. Bypass Factor = 0 indicates no psychometric solution. Use bypass factor of next lower EWB for approximation.
