POWER Depress to switch power on or off (switch illuminates when power is on). 2. THERMOSTAT Temperature range 50 - 250°C. Light illuminates when elements are cycling ON to maintain set temperature. 1 3. BAKE TIMER 1 Hour bake timer. (Light illuminates when “time up” (0) reached, and buzzer sounds). 4.
3.2 ‘Off’ position, the element relies on the thermostatic control to prevent it switching on. Accordingly, if the oven temperature drops below approximately 20°C the thermostat and element may cycle on at this setting. EXPLANATION OF CONTROL SYSTEM The E26 Turbofan convection ovens feature multi-function operator controls for which a correct understanding of their operation is required before carrying out any service or fault repair work.
4. MAINTENANCE WARNING: ALL INSTALLATION AND SERVICE REPAIR WORK MUST BE CARRIED OUT BY QUALIFIED PERSONS ONLY. 4.1 CLEANING OVEN SEALS To remove, hold at their centre point and pull forward until they unclip.
