NOTE: On 4 ton models, switch to medium speed for cooling if external static pressure is less than 0.4" W.C. at 230 volts or less than 0.3" W.C. at 208 volts.
	WARNING: Do not operate unit in area of airflow table shown in bold (CFM greater than 1700 for 4 ton models) due to possibility of water blow-off.
	WARNING: Observe airflow operating limits if operating in area of airflow table shown in bold.
