*Air delivery values are without air filter and are for dry coil. See
Table 11 for wet coil pressure drop. Deduct field-supplied
air filter
pressure drop and wet coiI pressure drop to obtain external static
pressure available for ducting.
1-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.
