SEASONING

The metal surface of the griddle has microscopic pores. It is important
to fill the pores with oil to provide a hard, non-stick cooking surface.

1. Turn GRIDDLE TEMPERATURE CONTROL (G.01) clockwise to
375ºF. Allow the griddle to heat until the GRIDDLE HEAT ON

set temperature.

2. Spread a light film of oil over the entire griddle surface.

3. Allow the oil film to "cook in" for 2 - 3 minutes, or until the oil
smokes.

4. Wipe the griddle surface with a clean cloth to remove any standing
oil.

OPERATION HOTPLATE OPERATING INSTRUCTIONS

COOKING WITH YOUR HOTPLATE

1. Each element is individually controlled by a TEMPERATURE
CONTROL (H.01 and H.0 3). These are infinite switch controls
which control based on time on vs time off, not the actual
temperature of the hotplate surface.

2. Settings are OFF to HIGH. Switch position is an indication of
temperature in that higher numbers indicate a higher temperature.

3. The associated indicator will be lit when the switch is in any
position other than OFF.

4. When set to HIGH, the hotplate element can reach maximum
temperature in secon ds. This eliminates the need to pre-heat.

5. Once liquid begins to boil, reduce the setting to minimize power
consumption and increase the useful life of the elements.

6. Use cooking pans which fully cover the elements for maximum
efficiency.
