*Airflow reduced to 4000 SCFM at this condition to maintain adequate return gas temperature.
Note: Unit is not recommended for use with total loads of 10 kW or less.
Note: Shaded lines represent leaving air temperatures above ASHRAE specifications of 25°C (77º F) at maximum airflow.
Note: Reduce airflow and cooling capacity specifications by 7% for cooling units run at low input voltage (380 V).
