*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.
†Size 048 is 460 v.
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 capacity. Evapo-
rator coil frosting may occur at airflows below this point.
2. Dashes indicate portions of table that are beyond the blower mo-
tor capacity or are not recommended.

*Air delivery values are for dry coil at 230 v. Airflow is independent of
external static pressure within
Ϯ
5% of table values up to
0.8 in. wg.
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. Evaporator-
coil icing may occur at airflows below this point. Water blow-off may
occur at airflows above 450 cfm per 12,000 Btuh of rated cooling
capacity.
