RADIANT HEATING ELEMENT SYSTEMS
Heating Elements: The radiant heating element consists of a spiral-wound resistance
wire attached to microporous insulation with molded ceramic fiber walls in a corrosion-
protected metal tray.
The Heating Elements come in various sizes:
• 6" - 240 Volt, 1500 Watts
• 8" - 240 Volt, 2000 Watts
• 12"/9" - 240 Volt, 3600 Watts
• 6"/9" - 240 Volt, 3000 Watts

TEMPERATURE LIMIT/HOT LIGHT SWITCH
The Temperature Limit/Hot Light Switch performs two functions:
1. Turns on HOT LIGHT when the glass surface above the heating unit has reached
150°F. The hot light will remain on until the glass surface above the heating unit has
cooled below 150°F (even after the surface unit switch has been turned off).
2. Detects when the glass temperature above a u nit has exceeded its limit
of approximately 1031°F and disconnects power to that unit. When the glass
temperature cools below 1031°F, the unit will turn back on. The temperature limit/hot
light switch cannot be calibrated.

• Clear/Off – An audible tone sounds and the display shows the time of day.
• Number pads can only be used after another function has been selected.
• Oven Light - Oven light turns on. Audible tone. Relay click.
ELECTRONIC OVEN CONTROL
CAUTION:
Components are electrically HOT on control when
voltage is connected to oven. The Electronic Oven Control system consists of the
control, key panel, oven sensor, door and lock assembly.
NOTE: Temperature/Mode Selection necessary for operation of Relay contacts.
VOLTAGE MUST BE PRESENT ACROSS TERMINALS L1 TO N FOR CONTROL TO
OPERATE.

STEAM CLEAN OPERATION
The Steam Clean feature operates in the following manner:
1. Control checks for the oven temperature to be less than 120 F using the sensor
circuit. IF the temperature is 120 F, the control displays HOT and does not allow the
cycle to begin.
2. Control energizes the lock motor until the door is locked. The door lock will operate as
indicated in the "Motorized Door Lock" section of the manual.
3. Bake element turns on full power to 3 minutes.
4. After 30 minutes the Steam Clean LED flashes and beeper beeps until Clear/Off is
pressed.
