*Air delivery values are without air ®lter and are for dry coil. See Table 17 for wet coil pressure drop. Deduct ®eld-supplied air ®lter pressure drop and wet coil pressure drop to obtain external static pressure available for ducting.

²Unit air delivery is outside of operating range.

NOTE: Do not operate the unit at a cooling air¯ow that is less than 350 cfm for each 12,000 Btuh of rated cooling capacity. Evaporator- coil icing may occur at air¯ows below this point. Water blow-off may occur at air¯ows above 450 cfm per 12,000 Btuh of rated cooling capacity.
