Specifications subject to change without notice.
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 (h

total capacity (Btuh)
4.5 x CFM
Where h
EWB
= enthalpy of air entering coil
3. SHC is based on 80F db temperature of air entering the evaporator coil.
Below 80 F db, subtract (Correction Factor x CFM) from SHC.
Above 80F 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 10F superheat leaving coil and use of thermostatic expansion valve (TXV) device.
7. All units have sweat suction- tube connection and a liquid- tube connection. For 1 - 1/8 in. system suction tube, 3/4 x 1 - 1/8 in.
suction tube connection adapter is available as accessory.
8. The EAM4X coils can be used in any properly designed system using Refrigerant R- 410A.
9. 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.
10. Bypass Factor = 0 indicates no psychometric solution. Use bypass factor of next lower EWB for approximation.
