By default the maximum blower CFM is set to 650.
To verify if your installer enabled ACT; With hood off, press and hold the blower on/off button for three
seconds. If the number 6 displays = defualt max. CFM, if the number 3 displays = max. 390 CFM, and
if the number 2 displays = max. 290 CFM. When ACT is enabled, the number of blower speeds will be
reduced. 390 CFM = max. 3 speeds and 290 CFM = max. 2 speeds. There should also be a foil label
located inside the hood body near the wiring diagram that indicates the blower CFM.
