maximum blower CFM of select Zephyr Ventilation range hoods without the need for expensive make up air kits.

levels; 590, 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 750.
ACT™ NOT AVAILABLE WITH 1300 CFM DUAL INTERNAL BLOWER OPTION
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 off, hold the On/Off button for three seconds. The Display will show if ACT™ is disabled and set to the
maximum CFM or if ACT™ is enabled and set to one of the restricted maximum CFM levels of 590, 390 or 290.
There should also be a foil label located inside the hood body near the wiring diagram that indicates the blower CFM.
