NOTES:

1.Rated in accordance with ARI Standards 360 and 270.

2.The 579F300 is beyond the scope of the ARI Certification Program.

3.ARI ratings are net values, reflecting the effects of circulating fan heat.

4.Ratings are based on:

Cooling Standard: 80 F db, 67 F wb indoor entering-air tempera- ture and 95 F db air entering outdoor unit.

IPLV Standard: 80 F db, 67 F wb indoor entering-air temperature and 80 F db outdoor entering-air temperature.

*All units are 2-stage heat.

NOTE: Minimum allowable temperature of mixed-air entering the heat exchanger during first-stage heating is 45 F. There is no minimum mixed-air temperature limitation during second-stage heating. For entering-air temperatures below 45 F both stages of heat must be energized together to minimize condensation issues and ensure proper unit operation.
