Enabling ACT™
To enable ACT™:
1. Before hood installation, gain access to PC board by following the steps shown on FIG. D.
2. Change plastic jumper positioning as shown in FIG. E to set the desired maximum blower CFM.
3. Re-install PC board and 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.
To verify if your installer enabled ACT™:
1. Model Typhoon AK21:
With hood off, hold down the power button for 5 seconds. If all speed level
indicators illuminate = default max. CFM, if speed Q, 2 & 3 level indicators illuminate = 390 max.
CFM, if speed Q & 2 level indicators illuminate = 290 max. CFM.
Model Hurricane AK25:
With hood off, hold down the power button for 5 seconds. If all speed level
indicators illuminate = default max. CFM, if speed 1 & 2 level indicators illuminate = 390 max. CFM,
if speed 1 level indicator illuminate = 290 max. CFM
2. When ACT™ is enabled, the number of blower speeds will be reduced as follows:
Model Typhoon AK21:
390 CFM = max. 3 speeds, 290 CFM = max. 2 speeds
Model Hurricane AK25:
390 CFM = max. 2 speeds, 290 CFM = max. 1 speed
3. There should also be a foil label located inside the hood body near the wiring diagram that
indicates the blower CFM.
