NOTES:
1. Formulas:
Leaving db = entering db —
Leaving wb = wb corresponding to enthalpy of air leaving coil (h
LWB
)

—
where h
EWB
= enthalpy of air entering coil.
2. Direct interpolation is permissible. Do not extrapolate.
3. Fan motor heat has not been deducted.
4. All data points are based on 10°F superheat leaving coil, and use of thermal expansion valve device.
5. 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.
6. Check-Flo-Rater pistons (sized for matched cooling-only systems). Refer to outdoor unit installation instructions for pistons required for other systems.
7. The CD5A and CC5A coils can be used in any properly designed system using R-22 or Puron® 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.
Interpolation is permissible.
