Off : Pressing button once turns blower off and resets control.
Fan Speed : Pressing button once, from an off state, turns the blower on low. Each
successive press of the button increases the fan speed until high where 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
Delay Shut Off : Press to turn fan on high for 5 minutes.
If the blower is off when the delay button is pressed, the ventilator will turn on to the high
speed setting for 5 minutes. At the end of the cycle the blower will turn off.
If the ventilator is on when the delay button is pressed, the blower runs for:
·15 minutes for low speed
·7 1/2 minutes for medium speed
·5 minutes for high speed
During a timed period, the LED above the Delay Shut Off button is illuminated.
To interrupt a timed period, press Fan Speed or Off button.
Filter: After 40 hours of operation, the clean filter reminder LED above this button will
illuminate indicating that the filters need to be cleaned. After cleaning, press this button
for 3 seconds to reset the 40-hour period and turn the LED off.
Light: This button controls the halogen lighting. The first press turns the lights on. A
second press dims the lights. A third press turns the lights off.
Heat Lamp: The buttons marked L and R independently control the left and right
infrared heating lamps, turning the lights on or off.
Heat Sensor: Your hood is equipped with a heat sensor that will turn the blower to Low speed
if excessive heat occurs above the cooking surfaces.
1. If the blower is off it turns the blower on to low speed.
2. If the blower is already on any speed selection, no speed change will occur.
When the temperature level on the hood drops to normal, the blower will return to its
original setting.
Overtemperature : The high temperature sensor protects the hood from high temperatures
which may damage components. The control is set to activate at 161º F (72º C) and reset
at 140ºF (60º C). When activated, the ventilator will turn on low and the corresponding
LED will blink, indicating an over temperature condition.
While the high temperature sensor is activated, the blower speed can be changed or turned
off. If the blower is turned off, the corresponding LED will blink. Light controls will remain
operational. When the control sensor reaches 140ºF (60º C), a reset will occur. During
reset, the control will revert back to the operational state prior to the high temperature
condition.
High Temperature Fault Condition: The circuit is equipped with an alarm indicating that
the heat sensor protection is not working, due to a damaged sensor. In the case of this
extreme condition, the three speed indicator LEDs will start blinking. All the controls will
be operational except for the speed indicators.
