*Minimums are for all except CCN controls, which may be lower. Minimum for DDC by
others is to be provided by the control’s provider.
†A minimum 0.03 in. wg discharge static pressure is required to set the flow switch in the
electric heater.
**Maximum discharge temperatures with electric heat are set at 120 F by the National
Electric Code. Max kW shown assumes 55 F entering air and is limited by unit’s selected
voltage, phase, max capacity and design (see Electrical Data in the Product Data cata-
log). Min cfm for electric heat is based on UL/ETL listings. (Diffuser) performance will
likely be poor at this low flow rate.) The ASHRAE (American Society of Heating, Refrig-
eration and Air Conditioning Engineers) Handbook of Fundamentals does not recom-
mend a discharge temperature exceeding 90 F for satisfactory air mixing and comfort.
††Max. kW is limited by design.
NOTES:
1. To obtain Total Pressure (Pt), add the Velocity Pressure for a given cfm to the Static
Pressure drop (∆ P
S
) of the desired configuration.
Example: Pt for a Size 8 Basic Unit at 925 cfm = 0.39 + 0.17 = 0.56
2. The electric heat max kW is based on 3 phase power. For more details, refer to the air
terminal selection program.
