*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 capacity. Indoor 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.
