Seasoning the Griddle Before a new griddle is used, it must be seasoned to prevent permanent discoloration and staining.

1. Clean the griddle thoroughly with hot, soapy water to remove any protective coating.

2. Wipe the surface using a solution of 1 quart water and 1 cup white vinegar. Dry thoroughly.

3. Brush 1 tablespoon vegetable shortening evenly across the griddle. Do not use corn oil as it can get sticky.

4. Turn the control knob to 350F for approximately 30 minutes. Turn the heat off when the oil begins to smoke. Allow the griddle to cool.

5. Repeat Step 3. Be sure to cover the entire surface with the shortening.

6. Repeat Step 4. Allow the griddle to cool. Wipe the entire surface of the griddle using a heavy cloth. Brush the surface with a very thin layer of shortening. The griddle is now ready to use.

Reed Switch Board RPM Feedback

Each cooling fan uses a reed switch board to provide RPM feedback to the control. A magnet is mounted on the squirrel cage blade. As the magnet passes by the reed switch board, the board generates a pulse.

80

Oven Control Logic Board

A front panel logic board controls oven operation through user input and feedback from the oven sensor and switches.

81

Oven control is located behind the front panel.

82

Oven Control Features

Electronic dial control. The larger outer bezel or dial controls the cooking mode, while the center dial knob controls temperature.

A red font indicates a temperature setting.

A green font indicates a timer or display setting.

83

Self Clean Features

On double oven models, the ovens can be set to self clean in sequence. The first oven set starts the cycle. Cleaning defaults to 5 hours, but can be adjusted between 3 to 5 hours in 15 minute increments. The control will display End when the self-clean cycle is complete.

84

Also on double oven models, one oven can be used for cooking functions while the other oven is cleaning (not recommended for Proof Cycle). All range top functions are locked out.

85

Special Features

Thermostat adjustment (displayed as OFFSEt).

Sabbath mode (displayed as SAbbAth).

Press and hold both the Timer and the Push to Select knobs on the main oven for approximately 4 seconds. The display will show SF. Choose a feature by rotating the Push to Select knob clockwise or counter-clockwise and pushing the knob. If a feature isnt selected in 60 seconds, the Special Features mode is cancelled.

86

Temperature can be offset by +/- 35F in 1F increments. The adjustment will only affect Bake, Convection Bake and Convection Roast. It does not affect broiling or self-cleaning temperatures. The adjustment will be retained in memory after a power failure. Set the offset by rotating the Push to Select knob of the desired oven, once the offset is entered, push the the large ovens Push to Select to set the temperature.

Offset Mode

87

Sabbath Mode

Sabbath mode can be used for baking only.

When the Sabbath feature is set, the oven lights, convection fan and all audible beeps will be disabled.

The feature will also provide a random delay period, of approximately 30 seconds to 1 minute, before the oven will turn on once it is set to BAKE.

The main oven control will control both ovens. The Sabbath feature symbol will appear in both oven display windows.

Proof Cycle

The display will scroll too hot above 125F and start the Proof cycle only when the oven cools below that set point.

The Proof cycle maintains a 95F oven temperature by cycling the halogen oven lights.

Note: Proof is the only cycle where the inner knob does not need to be set. It can stay in the off position.

89

Control Panel Lighting

LED lighting on all models. On/Off switch on panel.
