Operation
Operating the Hood
The blower should be turned on for about 5 minutes before 
cooking in order to establish air currents upward through 
the hood. Thus when heat, smoke, moisture, grease and 
cooking odors are produced, they will be carried outside 
instead of drifting into other rooms. Use the low speeds for 
normal use and the higher speeds for strong odors or 
fumes. 
Drafts across the range or cooktop will reduce the 
effectiveness of the hood. Such drafts should be prevented 
when possible. 
The best job of ventilation in the kitchen is done where the 
only air currents are those created by the blower itself.

Hood Control Buttons
Off 
Pressing the button once turns ventilator off and resets the 
control. 
Fan Speed 
Pressing the button once, from an “off” state, turns the 
ventilator on low. Each successive press of the button 
increases the fan speed until high speed is reached, then 
the fan cycles back to the low speed. 
The LEDs above this button indicate the current fan 
speed. When the fan is on, the corresponding LED is 
illuminated. 
1 — Low
2 — Medium
3 — High
Auto (only on 27” depth models)
When in Auto mode, the hood automatically turns the 
blower on, depending on the amount of heat the control 
senses. It automatically adjusts every 5 minutes. If the 
control does not sense a high level of heat, it will turn the 
blower off. 
Delay Shut Off 
Press Delay button to turn fan on high for 10 minutes.
If the ventilator is off when the Delay button is pressed, 
the ventilator will turn on to the high speed setting for 
10 minutes. At the end of the cycle the ventilator will 
turn off. 
If the ventilator is on when the Delay button is pressed, 
the ventilator runs for 10 minutes at the current speed 
then turns off. 
During a timed period, the LED above the Delay button 
is illuminated.
To interrupt a timed period, press Fan Speed or Off 
button.
