NOTE: Low cool (W1) airflow is 65% of high cool airflow.
Blower speed adjustments should be done by moving the COOL jumper on the control
board. DO NOT move the motor wires to different positions on the furnace control board.
NOTES:
1. Airflow expressed in standard cubic feet per minute (CFM).
2. Return air is through side opposite motor (left side).
3. In order to stay within the velocity rating the filters, airflows above 1800 CFM require either return from two sides or one side plus bottom.
4. Motor voltage at 115 V.
FILTER PERFORMANCE
The airflow capacity data published in the "Blower Perfor-
mance" table listed above represents blower performance
WITHOUT filters. To determine the approximate blower per-
formance of the system, apply the filter drop value for the fil-
ter being used or select an appropriate value from the "Filter
Performance" table shown.
NOTE: The filter pressure drop values in the "Filter Perfor-
mance" table shown are typical values for the type of filter
listed and should only be used as a guideline. Actual pres-
sure drop ratings for each filter type vary between filter manu-
facturer.
