ACT Conversion
AIRFLOW CONTROL TECHNOLOGY (ACT)
Some local codes limit the maximum amount of CFM a range hood can move. ACT allows you to control the
maximum blower CFM of the range hood without the need for expensive make up air kits. ACT enables the installer
to easily set the maximum blower speed to one of two most commonly specied CFM levels; 390 or 290 CFM. The
usage of ACT may not be necessary for your installation. Please check your local codes for CFM restrictions.
By default the maximum blower CFM is set to 600.
To enable ACT
1. Before hood installation, gain access to PC board by following the steps shown in FIG. C.
2. Change plastic jumper positioning as shown in FIG. D to set the desired maximum blower CFM.
3. Re-install PC board & continue with hood installation.
4. Remove the appropriate foil CFM sticker included with the hood literature and place inside the hood body below
the wiring diagram or in another clearly visible location.
NOTE: After re-positioning the jumper and powering on the hood, the CFM cannot be changed again.
To verify if your installer enabled ACT
With hood o󰀨, press and hold the power button for ve seconds. If 3 LEDs illuminate = defualt max. CFM, if 2 LEDs
illuminate = max. 390 CFM, and if 1 LEDs illuminate = max. 290 CFM.
When ACT is enabled, the number of blower speeds will be reduced. 390 CFM = max. 2 speeds and 290 CFM =
max. 1 speeds.
There should also be a foil label located inside the hood body near the wiring diagram that indicates the blower
CFM.
