BLOWER PERFORMANCE

• Performance based on factory-provided washable filter installed in the unit.
• If a higher resistance filter is field installed in the unit, the added resistance must be included in the external static pressure and must not exceed 0.5 in. w.c. including ductwork
• Refer to Factory Filter Size and Pressure Drop table for additional details

N/A: Do not operate unit using this blower speed at this external static pressure.
† As shipped speed for Cooling operation. Blower speed must be field adjusted to speed Tap 2 for lower duct static applications.
* As shipped speed for Heating operation. Blower speed must be field adjusted to speed Tap 5 for higher duct static applications.
# As shipped speed for Low Stage Cooling operation (low duct static).
