22 2.0 Installation 2.1 Installation Manual For installation information, refer to the Miele installation information manual for residential appliances or the model-specific operating manual. Figure 2-1: Miele Installation Information Manual for Residential Appliances 22

23 2.2 Installation Guide A single-page installation guide is included with each appliance. Figure 2-2: Installation Guide (Included with Each Oven) 23

24 3.0 Commission and Operation 3.1 General Operation Selecting and Starting a Program 1. Touch the ON ( ON/OFF on double ovens) control. 2. Select the desired function (e.g., BAKE). 3. Select the desired operation from the submenu (e.g., CONVECTION BAKE). 4. Select the temperature (e.g., 425 F) Turning Off the Appliance To turn off the oven, touch the "OFF" ( ON/OFF on double ovens) control. The oven will turn off and the time of day will appear in the display. 3.2 Power Failures If the oven should lose power during operation, a Power Failure message is displayed, as shown in Figure :23 PM Power Failure Figure 3-1: Power Failure Message (H 39x Display Shown) This message is displayed to advise that the incoming power was disrupted (power failure, etc.). It does not require any type of technical service. The Power Failure message can be cleared via the following procedure: 1. Turn the oven on by touching the ON or ON/OFF control. 2. Turn the oven off by touching the OFF or ON/OFF control. The message clears. 3.3 Special Features Self-Clean Function ( P Models Only) When the self-clean function is selected, the oven is heated to very high temperatures to burn off any residue inside the oven cavity. The self-clean function is not a timed function and its duration is based on the amount of soiling inside the oven cavity. Total time will vary depending on the condition of the oven interior. Once the self-clean program completes and the oven cools, wipe the interior with a damp cloth to remove any remaining residue. 24

25 3.3.2 Door Lock ( P Models Only) The door lock is operated via a motorized control. During the self-clean procedure, the door automatically locks after one (1) minute. The door remains locked until the self-clean process has completed and the oven temperature has dropped below 392 F (200 C). If the self-clean function is accidentally started, shut off the oven and wait for the oven temperature to drop and for the door lock to release. This may take several minutes. The door lock can be activated via service mode. See Section MasterChef (Where Applicable) The MasterChef menu feature is designed to ease operation and improve cooking results. This feature uses a list of selectable preset functions for commonly cooked foods. Users can select the type of food from a menu and simply reply to a few basic inputs (e.g., weight). The oven performs the necessary functions automatically to ensure a perfectly cooked meal Child Safety Lock (All Models) The child safety lock is used to prevent children from operating the oven or to conserve standby power when the oven will not be used for an extended period of time. Figure 3-2: Child Safety Lock To activate the child safety lock: 1. Slide the lock to position O. 2. The oven cannot be operated and the clock will not be displayed. To deactivate the child safety lock: 1. Slide the lock to position I. 2. The oven can then be operated and the clock will be displayed. Warning! Using the child safety lock does NOT disconnect all sources of power within the oven. To safely disconnect power during service shut off the main supply via the circuit breaker. Note: For further detailed appliance operation, refer to the model-specific operating manual. 25

The air flows between the outer and inner glass panes and into the area between the housing and upper holding plate insulation mat. 4.2 Vapor Intake The cooling fan takes in the vapor through the vapor outlet (Figure 4-1, Item 8) and the exhaust duct (Figure 4-1, Item 10). 4.3 Cooling Air Path The cooling fan moves the air and vapor into the air vents (Figure 4-1, Item 7) and through the opening between the bottom plate and the lower insulation mat (Figure 4-1, Item 5). 4.4 Cooling Air Exit The cooling air exits via the opening between the vent strip and bottom plate (Figure 4-1, Item 4). 4.5 Door Contact Switch The door contact switch monitors the opening and closing of the door. If the door is opened during cooking, the convection fan and heater elements for the appropriate oven are turned off. 4.6 Heater Elements Each oven cavity is equipped with four heater elements.

29 4.8 Oven Cavity Temperature Sensor The oven cavity temperature sensor is located in the guide tube of the upper heater elements (Figure 4-2, Item 1). The sensor sends a signal back to the main electronic. The oven cavity temperature is calculated and displayed via the display electronic. Figure 4-2: Upper Heater Element Cavity Temperature Sensor 4.9 Roast Probe The roast probe can be used to monitor the core temperature of meat and poultry. The long pointed end of the probe is inserted into the thickest portion of the meat. The short end of the probe is inserted into the roast probe socket located on the right side of the oven cavity. For optimum cooking results ensure that the probe does not contact any bones within the meat or poultry. Figure 4-3: Roast Probe 4.10 Self-Clean Temperature Sensor ( P Models Only) The self-clean temperature sensor is located in the vapor outlet (above the catalyst) and monitors the oven temperature during the self-clean mode. See Figure

30 Figure 4-4: Self-Clean Temperature Sensor (1) and Catalyst Vapor Outlet (2) 4.11 Oven Cavity Thermostat Each separate oven cavity is equipped with a high-temperature thermostat (thermal cutout). The thermostat is designed to interrupt the power in case the temperature exceeds 680 F (360 C) during normal operation Self-Clean Thermostat ( P Models Only) Each separate oven cavity is equipped with a self-clean thermostat designed to interrupt the power should the temperature exceed 968 F (520 C) during the self-clean mode Convection Fan The convection fan is mounted to the rear wall of the oven cavity. It pressurizes a large volume of air in the small cavity located in the rear wall of the oven to produce true convection. Figure 4-5: Convection Airflow 30

31 4.14 Rotisserie Motors Two 120VAC rotisserie motors are mounted to the rear wall of the oven. These motors drive the rotisserie shafts Oven Cavity Lights There are two oven cavity lights in each oven. Two transformers mounted in the top of the oven power the lights. Light voltage Light output 12VDC 10W 4.16 Automatic Door Lock ( P Models Only) When the self-cleaning program begins, the door lock motor activates and locks the door. The door cannot be opened until the temperature drops below 398 F (200 C).

32 5.0 Service and Maintenance 5.1 Cleaning and Care Information PerfectClean PerfectClean is a smooth, nonstick surface that cleans up easily with a sponge. The following items are coated with the exclusive Miele PerfectClean finish: Oven walls Roasting pans Anti-splash tray Oven runners Do not clean PerfectClean items in a dishwasher. Some detergents contain compounds that could damage the finish. To properly clean the surfaces, use a sponge and a solution of hot water and liquid dish soap for cleaning. Do not use abrasive cleaners, ceramic cleaners, metal scourers, or oven cleaners. After cleaning, rinse thoroughly with water. The water should run off the surface easily. Any residue will hinder this effect. Stubborn baked-on grease may need to be soaked first to loosen deposits. Clean up all spills as soon as possible to prevent stains. Spilled fruit juices can permanently discolor surfaces; however, this discoloration does not hinder the efficiency of the finish Manually Cleaning the Oven Cavity Danger! Allow the oven to cool before cleaning. To make cleaning easier, remove the oven door, remove the runners, and lower the upper heater element. Clean the oven surfaces with a solution of hot water and liquid dish soap and a sponge. Do not use abrasive cleaning agents, hard brushes, metal scouring pads, steel wool, knives or other abrasive materials. Do not use oven sprays on any part of this oven. Dry surfaces before reassembly. 32
