LEGEND AND NOTES FOR TABLES 11 AND 12

*Air delivery values are without air fiiter and are for dry coil. See Table 14 for wet coil pressure drop. Deduct field-supplied air filter pressure drop

and wet coil pressure drop to obtain external static pressure available for ducting

tUnit 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.
