*Air delivery values are without air filter and are for dry coil. See
Table 17for wet coil pressure drop.Deduct field-supplied air filter pres-
sure drop and wet coil pressure drop to obtain external static pressure
available for ducting.
†Unit air delivery is outside of operating range.
NOTE: 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
icing may occur atairflows below this point. Water blow-off may occur at
airflows above 450 cfm per 12,000 Btuh of rated cooling
capacity.
