NOTES:
1. Recommended temperature rises are highlighted in BOLD. Use of any other setting may result in nuisance trips.
2. Temperature rises in the table are approximate. Actual temperature rises may vary.
3. Blower “ADJUST” tap non-functional in Heating mode.
4. To comply with government mandated efficiency standards, two openings are required for airflows above 1,600 CFM.
5. Individual cells shaded in gray indicate a temperature rise outside of the recommended range.
6. To comply with government mandated efficiency standards, speed settings which do not have data are not allowed in heat and cooling mode.
