ELECTRIC COMBI OVEN - ELECTRICAL OPERATION

Steam Mode

1.Conditions exist as described in “POWERING CONTROL”.

2.With the selector knob rotated to STEAM, the cooking cycle begins..

A.Time LED is on and “- -:- - “ is displayed in the time display.

B.Cavity set point temperature (default) is displayed in the temperature display. If the oven has not been turned off, the previous set point temperature is displayed.

C.With the water at the proper level in the steam generator, steam generator heating elements are energized and cycle as described in “STEAM MODE” under

“STEAM REGULATION”.

NOTE: When degree symbol shows in the temperature display, steam generator heating elements are energized.

1)If oven cavity temperature is below set point temperature, the steam generator heating elements turn on at full power until steam temperature is reached, then turn off.

2)If oven cavity temperature is above set point temperature, the oven performs an automatic cool down as described under “WATER INJECTION (HUMIDIFIER)”, then the steam generator heating elements turn on.

D.Drain cool down solenoid energized.

NOTE: Whenever steam generator heating elements are on, the drain cool down solenoid is energized.

E.Cavity fan motor(s) energized.

3.Press the temp key to set the operating temperature. The temperature symbol (°F or °C) will flash in the temperature display to indicate the cavity set point temperature can be adjusted. The default temperature displayed (195 to 212°F) is pre-selected in the configuration mode and is the steam temperature setting (boiling point adjustment) for elevation. The adjustable operating range is 35 to 212°F. See “CONFIGURATION MODE - MANUAL CONTROLS” under “SEQUENCE OF OPERATION”.

A.Rotate the adjustment knob clockwise or counterclockwise to adjust the setting (temperature symbol stops flashing).

1)If a pause of 5 seconds is made during or at the end of the adjustment, the temperature symbol will begin to flash. When the temperature symbol stops flashing, the temperature can no longer be adjusted and the cavity set point temperature is displayed.

NOTE: To display the actual cavity temperature for several seconds, press and hold the temperature key.

4.Oven control monitors cavity temperature and cycles the steam generator heating elements as necessary, to maintain set point temperature.

A.The operating temperature remains as entered unless the operating temperature setting is changed or the oven is turned off.

Combi Mode

1.Conditions exist as described in “POWERING CONTROL”.

2.With the selector knob rotated to COMBI, the cooking cycle begins.

A.Time LED is on and “- -:- - “ is displayed in the time display.

B.Cavity set point temperature (the last temperature that was set) is displayed in the temperature display.

C.Deluxe Manual Control - COMBI key LED turns on and 3 LED’s in the combi window turn on, indicating the default steam factor setting of 20.

1)Press COMBI key an additional 1 to 3 times to increase the steam factor setting from 30 to 50. With each successive key press, an additional LED illuminates to indicate the setting. This will be the “new” default combi setting until manually changed.

D.Standard Manual Control - A fixed steam factor setting of 20 is used. The combi key and the combi window are not present on this control.

E.Convection heating elements energized and cycle as described under “HEATING REGULATION”.

F.Steam generator pre-heats (initial start up only) as described under “STEAM PRE- HEAT”.

NOTE: When degree symbol shows in the temperature display, convection and/or steam generator heating elements are energized.
