*Air delivery values are based on operatin g voltage of 400---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 un it a t a cooling a irflow 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 airflow below this point.
2. Dashes indicate portions of table that are beyond the blower motor capacity or are not recommended.
