* Air delivery values are based on operating voltage of 230v or 460v, wet coil, without filter or electric heater. Deduct filter and electric heater pressure drops to obtain
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. Evaporator 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.
