*Air delivery values are without air filter and are for dry coil. See
Table 17 for 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 at airflows below this point. Water blow-off may occur at
airflows
above
450
cfm
per
12,000
Btuh
of
rated
cooling
capacity.
