2.32 Self-Clean Pyrolytic Cycle

Duration: 3hrs

Pyro Temp: 925°F (500°C)

Heat-up time: 50 minutes approx.

Holding time: 100 minutes approx.

Cool-down time: 30 minutes

 If a Self-Clean Cycle will not start, check that there are no meat probes inserted and that

the control knobs of the cavity that is not being cleaned (in a double oven) are in the

‘OFF’ position.

 The oven self-clean mode operates by heating the oven to a temperature of

approximately 925°F (500°C). This burns off and breaks down soil and grease deposits.

The ash residue that remains can simply be removed from the cool oven with a damp

cloth or sponge. The self-clean cycle normally takes about three hours.

 To start a Self-Clean Cycle

1. Turn the oven mode dial until ‘Self Clean’ appears in the display.

2. Select the maximum temperature using the temperature dial.

 ‘000’ will appear in the temperature display. This will change to when the

cycle begins.

 ‘Door Lock’ and ‘Clean’ will show in the clock display.

 The door lock will automatically activate once the Self-Clean mode and maximum

temperature have been selected.

 A countdown of minutes remaining will be shown in the clock display.  The Broil / Grill inner element, the throat element, the smoke eliminator element and the

vent fan operate during the Self-Clean Cycle. Additionally, during the first fifteen seconds

of each minute the bake element is on and during the third fifteen seconds of each

minute the Broil / Grill outer element is on.

 The cooling fan for the cavity being cleaned will be on high speed. The cooling fan for

the other cavity will be on low speed.

 During the Self-Clean Cycle in a double oven, the cavity not being cleaned cannot be

operated in any mode.

 The oven heats for its cleaning temperature and maintains this temperature

approximately 2½ hours into the cycle.

 The elements then turn off and the cool down period commences. When the

temperature reduces to 356°F (180°C) the door will unlock and the ‘Door Lock’ display

will disappear from the clock display.

 When the self-clean cycle has finished, ‘Clean’ and ‘00:00’ will flash in the clock display

until the product is returned to manual operation. Press the PUSH TO CLEAR button

and turn the oven mode and temperature dials to the OFF position to do this.

3.3 Temperature Dial and Display

This is turned to select the desired temperature.

3.4 Oven Modes

The oven has 9 cooking modes plus Warm and Self Clean. These use different combinations of elements and the oven fan as follows:

• True Aero. A concealed heating element surrounding the fan in the rear of the oven heats air, which is then blown into the oven cavity.

• Aero Bake. The oven fan circulates hot air from the upper outer and the bake elements.

• Bake. Heat comes from the upper outer and the bake elements.

• Aero Pastry. Heat comes from the bake element and is

circulated throughout the oven cavity by the oven fan.

• Pastry Bake. Uses the heat from the bake element only.

Page 22

Service Manual 599337A: 302B Series Titan Oven July 2006

• Warm. This is a constant low heat of 75 degrees C (165 degrees F) the oven fan circulates heat from the upper outer and the bake elements.

• Roast. This is a two step program where, during the first stage, the complete broil / grill element and the oven fan come on to sear the meat. The oven then automatically heats to the selected temperature for the remainder of the cooking time. During this latter part of the cooking, the oven fan is off and the upper outer and the bake elements provide the heating.

• Broil / Grill. Heat comes from the upper inner broil / grill element.

• Maxi Broil / Grill. Heat comes from both the upper inner and

outer broil / grill elements.

• Aero Broil / Grill. Heat comes from both the upper inner and outer broil / grill elements and is circulated throughout the oven cavity by the oven fan.

• Self Clean. Refer to Section 2.32 for an explanation of how this function operates.

3.5 Active Vent and Cooling Fans

 The active vent fan operates in all oven modes except Warm. It extracts oven cavity

air when the oven door is closed.
