LEGEND AND NOTES FOR TABLES 9 AND 10
*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. Evaporator-
coil frosting may occur at airflows below this point.
2. Dashes indicate portions of the table that are beyond the blower
motor capacity or are not recommended.
