ACT Conversion
A irflow 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 select Zephyr Ventilation range hoods 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 specified CFM
levels; 590 or 390 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 1200.
To enable ACT
1. Before hood installation, gain access to PC board by following the steps shown in FIG. G.
2. Change plastic jumper positioning as shown in FIG. H 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 3
LEDs illuminate = max. 590 CFM, and if 2 LEDs illuminate = max. 390 CFM.
When ACT is enabled, the number of blower speeds will be reduced. 590 CFM = max. 3 speeds and 390 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.
