ACT™ Conversion
Enabling ACT™
To enable ACT™:
1. Before insert installation, gain access to PC board by removing the PAS panel, grease filter, and
face plate. Refer to page 13, steps 3-6 for removing these parts.
2. Change plastic jumper positioning as shown in FIG. M to set the desired maximum blower CFM.
3. Re-install PC board and continue with insert installation.
4. Remove the appropriate foil CFM sticker included with the insert literature and place inside the
insert body below the wiring diagram or in another clearly visible location.
To verify if your installer enabled ACT™:
1. With insert off, press and hold the power button for three seconds. If the number 6 displays =
default max. CFM, if the number 3 displays = max. 390 CFM, and if the number 2 displays = max.
290 CFM.
2. When ACT™ is enabled, the number of blower speeds will be reduced.
390 CFM = max. 3 speeds and 290 CFM = max. 2 speeds.
3. There should also be a foil label located inside the insert body near the wiring diagram that
indicates the blower CFM.
