*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.
