CAUTION:
Hood must be disconnected from main power prior to performing the
conversion instructions listed below. Failure to do so could result in
personal injury or damage to the product.
To enable ACT
1. Before hood installation, gain access to PC board by following the steps shown in FIG. D.
2. Change plastic jumper positioning as shown in FIG. E 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 off, press and hold the power button for three seconds. If 5 LEDs illuminate = defualt max. CFM, if 4
LEDs illuminate = max. 390 CFM, and if 3 LEDs illuminate = max. 290 CFM.
When ACT is enabled, the number of blower speeds will be reduced. 390 CFM = max. 4 speeds and 290 CFM =
max. 3 speeds.
There should also be a foil label located inside the hood body near the wiring diagram that indicates the blower
CFM.
