* Air delivery values are based on operating voltage of 400-v, wet coil, without filter or electric heater. Deduct filter and electric heater pressure drop (see Tables 5 and
6) 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 (165 L/s for each 3.5 kW) 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.
