Notes
■
■
Airflow in CFM with wet coil and clean air filter.
■
■
All airflow is rated and shown above at the lower voltage if unit is dual voltage rated, e.g., 208V for 208-230V units.
■
■
Performance stated is at the rated power supply, performance may vary as the power supply varies from the rated.
