*Air delivery values are based on operating voltage of 230 v or 460 v, dry coil, without filter or electric heater. Deduct
wet coil, filter, and electric heater pressure drops to obtain external static pressure available for ducting.
NOTES:
1. Do not operate the unit at a cooling airflow that is less than 350 cfm for each 12,000 Btuh of rated cooling ca-
pacity. Indoor coil frosting may occur at airflows below this point.
2. Dashes indicate portions of table that are beyond the blower motor capacity or are not recommended.

*Air delivery values are for dry coil at 230 v. Airflow is independent of
external static pressure within
6
5% of table values up to 0.8 in. wg.
Air delivery is preset at factory.
NOTE: Do not operate the unit at a cooling airflow that is less than
350 cfm for each 12,000 Btuh of rated cooling capacity. Indoor coil icing
may occur at airflows below this point. Water blow-off may occur at air-
flows above 450 cfm per 12,000 Btuh of rated cooling capacity.
