NOTES:
1. To comply with government mandated efficiency standards, two openings are required for airflows above 1,600 CFM.
2. Data is shown without filter.
3. Temperature rises in the table are approximate. Actual temperature rises may vary.
4. Individual cells shaded in gray indicate a temperature rise outside of the recommended range.
5. To comply with government mandated efficiency standards, speed settings shaded in gray are not allowed in HEAT mode.
6. The “*” denotes the factory heat and cool setting. If a different motor speed is needed, the appropiate wire from the “HEAT” or “COOL” tap
on the control board must be connected to the desired Tap (1-5) at the motor.
