1. A filter is required for each return-air inlet. Airflow performance included 3/4-in. (19 mm) washable filter (see accessory list). To determine airflow performance without this filter, assume an
additional 0.1 In. W.C. available external static pressure.
2. Adjust the blower speed tabs as necessary for the proper air temperature rise for each installation.
3. -- Indicates unstable operating conditions.
4. If the same motor speed tap is needed for heating and cooling, a Jumper Wire accessory kit is available. (See Product Data sheet for the current Jumper Wire accessory part number). See
Function column for applicable limitations.

NOTES:
1.Two additional 7/8-in. (22 mm) diameter holes are located in the top plate.
2.Minimum return-air openings at furnace, based on metal duct. If flex duct is used, see flex duct manufacturer’s recommendations for equivalent diameters.
a. For 800 CFM-16-in. (406 mm) round or 14 1/2 x 12-in. (368 x 305 mm) rectangle.
b. For 1200 CFM-20-in. (508 mm) round or 14 1/2 x 19 1/2-in. (368 x 495 mm) rectangle.
c. For 1600 CFM-22-in. (559 mm) round or 14 1/2 x 22 1/16-in. (368 x 560mm) rectangle.
d. For airflow requirements above 1800 CFM, see Air Delivery table in Product Data Sheet literature for specific use of single side inlets. The use of both side inlets, a combination of 1
side and the bottom, or the bottom only will ensure adequate return air openings for airflow requirements above 1800 CFM.
