NOTES:
1. Data is shown without filter.
2. Temperature rises in the table are approximate. Actual temperature rises may vary.
3. Individual cells shaded in gray indicate a temperature rise outside of the recommended range.
4. To comply with government mandated efficiency standards, speed settings shaded in gray are not allowed in HEAT mode.
5. The "*" denotes the factory heat setting and "**" denotes the factory cool setting. If the Alternate speed is to be used, the speed
tap must be adjusted at the blower motor plug.
