*Air delivery values are based on operating voltage of 230 v or 460 v, 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 ariflow 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.
