The indicator lamp for the control will go out. ^ Press and hold the grease filter control. One or more of the indicator lamps for the ­ / + controls will flash. The number of flashing lamps shows the percentage of the operating time which has already been used up. 1 lamp 2 lamps 3 lamps 4 lamps = 25 % = 50 % = 75 % = 100 % The number of operating hours used remains in the memory, even when the appliance is switched off or there is a power cut. 15 Operation Altering the filter operating hours counter The filter operating hours counter is set at 30 hours. This can be lengthened or shortened to suit the type of cooking you do. You can choose 20, 30, 40 or 50 hours ­ Select a short time if you roast or fry a lot. ­ If you use very little fat for cooking, select a longer time. ­ If you only cook occasionally we recommend that you still select a short time, because grease which has built up gradually over a long period of time will harden on the grease filters and make cleaning more difficult. The ­ / + indicator lamps show the time which has been set: 1st lamp from the left = 20 hours 2nd lamp from the left = 30 hours 3rd lamp from the left = 40 hours 4th lamp from the left = 50 hours ^ Use the ­ / + controls to select the desired time. ^ Confirm the selection by pressing the grease filter control. If you do not confirm your selection within 4 minutes, the cooker hood will automatically revert to the "old" data. ^ Press the On/Off control to switch the fan off. ^ Press the run-on option control and the grease filter control at the same time. The indicator lamp for the grease filter control and one of the ­ / + indicator lamps will flash. 16 Cleaning and care Before any cleaning or maintenance work is carried out, disconnect the cooker hood from the mains supply. Ensure that: ­ it is switched off at the wall socket and the plug withdrawn, or ­ the fuse from the fused spur connection unit is withdrawn, or ­ the mains fuse is withdrawn, or ­ the screw-out fuse is removed (in countries where this is applicable). E-Cloth ^ A microfibre "E-Cloth" is available from the Miele UK Spare Parts Department, which is suitable for cleaning surfaces such as stainless steel, glass, plastic and chrome without the use of chemicals. Do not use too much water when cleaning the controls. Water could penetrate into the electronics and cause damage. Do not use: ­ cleaning agents containing soda, acids, chlorides or solvents, ­ abrasive cleaning agents e. g. powder cleaners or cream cleaners, and abrasive sponges, e. g. pot scourers or sponges which have been previously used with abrasive cleaning agents. Important for appliances with stainless steel housing (This infomation does not apply to the controls). Stainless steel surfaces can be cleaned using the Miele E-Cloth, or with a proprietary non-abrasive cleaning agent designed specifically for use on stainless steel. To help prevent re-soiling, a proprietary conditioning agent for stainless steel such as Neoblank (available from the Miele UK Spare Parts Department) can also be used. Follow the manufacturer's instructions, and apply sparingly with an even pressure in the direction of the "grain". Housing General notes The surfaces and controls are susceptible to scratches and abrasions. [. . . ] ­ The exhaust ducting should be as short and straight as possible. ­ To ensure efficient air extraction, the diameter of the exhaust ducting should not be less than 150 mm. If exhaust ducting with a diameter of less than 150 mm, or if flat ducting is used, the noise level of the cooker hood will increase and extraction will be less efficient. Only reduce the diameter of the ducting if absolutely necessary, e. g. [. . . ]
