NOTE:
1. A filter is required for each return ---air inlet. Airflow performance includes a 3/4 ---in. (19 mm) washable filter media such as contained in a factory ---author-
ized accessory filter rack. See accessory list in Specification sheet. To determine airflow performance without this filter, assume an additional 0.1 in. w.c.
available external static pressure.
2. ADJUST THE BLOWER SPEED TAPS AS NECESSARY FOR THE PROPER AIR TEMPERATURE RISE FOR EACH INSTALLATION.
3. The "Function" column identifies with speed taps can be used for heating. Shaded areas indicate that this airflow range is BELOW THE RANGE ALLOWED
FOR HEATING OPERATION. THESE AIRFLOW RANGES MAY ONLY BE USED FOR COOLING.
4. If the same motor speed tap is needed for heating and cooling, a Jumper Wire accessory kit is available, see Specification sheet for the current Jumper
Wire accessory part number. Reference the "Start---up, Adjustments, and Safety Check" section for further Jumper Wire instructions.
5. Airflows over 1800 CFM require bottom return, two ---side return, or bottom and side return. A minimum filter size of 20" x 25" (508 x 635 mm) is required.
6. For upflow applications, air entering from one side into both the side of the furnace and a return air base counts as a side and bottom return.
7. The " ---" entry indicates an unstable operating condition.
