Notes:
1.
Recommended temperature rises are highlighted in bold.
2.
Airflow rates of 1800 CFM or more require two return air connections. Data is for operation with filter(s).
3.
Temperature rises in the table are approximate. Actual temperature rises may vary.
4.
Temperature rises that are shaded grey are for reference only. These conditions are not recommended.
5.
For single stage cooling, the indoor blower will operate at the CFM listed in the high column.
