CFM Select
CFM SELECT
Some local codes limit the maximum amount of CFM a range hood can move. CFM Select allows you to control
the maximum blower CFM of the range hood without the need for expensive make up air kits. CFM Select enables
the installer to easily set the maximum blower speed to one of two most commonly specified CFM levels; 390 or
290 CFM. The usage of CFM Select may not be necessary for your installation. Please check your local codes for
CFM
restrictions.
By default the maximum blower CFM is set to 600.
To enable CFM Select
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 CFM Select
With hood off, press and hold the power button for five seconds. If 3 LEDs illuminate = defualt max. CFM, if 2 LEDs
illuminate = max. 390 CFM, and if 1 LEDs illuminate = max. 290 CFM.
When CFM Select is enabled, the number of blower speeds will be reduced. 390 CFM = max. 2 speeds and 290
CFM = max. 1 speeds.
There should also be a foil label located inside the hood body near the wiring diagram that indicates the blower
CFM.
