2. ARI ratings are net values, reflecting the effects of circulating fan
heat.
3. Ratings are based on:

*All units are 2-stage heat.
†Minimum heating cfm must be maintained to ensure proper heating operation.
NOTE: Minimum allowable temperature of mixed air entering the heat exchanger during first stage
heating is 45 F. There is no minimum mixed-air limitation during second-stage heating. For entering
air temperatures below 45 F, both stages of heat must be energized together to minimize conden-
sation issues and ensure proper unit operation. Mixed air below 35 F optional stainless steel heat
exchangers are recommended.
