Causes of damage

Caution!

Accessories, foil, greaseproof paper or ovenware on the
cooking compartment floor: do not place accessories on the cooking compartment floor. Do not cover the cooking compartment floor with any sort of foil or greaseproof paper. Do not place ovenware on the cooking compartment floor if a temperature of over 50 ºC has been set. This will cause heat to accumulate. The baking and roasting times will no longer be correct and the enamel will be damaged.
Water in a hot cooking compartment: do not pour water into
the cooking compartment when it is hot. This will cause steam. The temperature change can cause damage to the enamel.
Moist food: do not store moist food in the cooking
compartment when it is closed for prolonged periods This will damage the enamel.
Fruit juice: when baking particularly juicy fruit pies, do not
pack the baking tray too generously. Fruit juice dripping from the baking tray leaves stains that cannot be removed. If possible, use the deeper universal pan.
Cooling with the appliance door open: only allow the cooking
compartment to cool when it is closed. Even if the appliance door is only open a little, front panels of adjacent units could be damaged over time.
Very dirty door seal: If the door seal is very dirty, the
appliance door will no longer close properly when the appliance is in use. The fronts of adjacent units could be damaged.Always keep the door seal clean.
Appliance door as a seat, shelf or worktop: Do not sit on the
appliance door, or place or hang anything on it. Do not place any cookware or accessories on the appliance door.
Inserting accessories: depending on the appliance model,
accessories can scratch the door panel when closing the appliance door. Always insert the accessories into the cooking compartment as far as they will go.
Carrying the appliance: do not carry or hold the appliance by
the door handle. The door handle cannot support the weight of the appliance and could break.

Your accessories

The accessories supplied with your appliance are suitable for making many meals. Ensure that you always insert the accessories into the cooking compartment the right way round.
There is also a selection of optional accessories, with which you can improve on some of your favourite dishes, or simply to make working with your oven more convenient.
inserting the accessories
The accessories can be placed inside the oven on 5 different levels. Always insert them as far as possible so that the accessories do not touch the door glass.
  
The accessories can be removed halfway until they are secured. This makes it easy to remove food.
When inserting an accessory in the oven, make sure the curvature is at the rear. This is the only way to ensure it fits perfectly.
Note: Accessories may deform as they heat up. This deformation will disappear when they cool. This does not affect the normal operation.
Your oven is supplied with only some of the following accessories.
Accessories may be purchased from the Technical Assistance Service, from specialist retailers or on the Internet. Enter the HEZ number.
Wire shelf For cookware, baking tins, roasts, grilled items and frozen meals.
Insert the wire shelf with the open end facing the oven door and the curvature downwards
Flat enamel oven tray For cakes, pastries and biscuits.
Place the tray in the oven with its raised lip facing the door.
Universal deep enamel tray For juicy cakes, pastries, frozen meals and large joints for roasting. This can also be used as a tray to collect the fat when roasting directly on the wire shelf.
Place the tray in the oven with its raised lip facing the door.
Accessory support The universal deep tray or the flat oven tray can also be cleaned dur­ing the self-clean function.
Insert the accessory to the right and left.

Before using the oven for the first time

In this section, you can find out what you must do before using your oven to prepare food for the first time. First read the section on Safety information.
Setting the time
Once the oven has been connected, the 0 and :‹‹ symbols light up on the display panel. Set the clock to the right time.
1. Press the 0 sensor.
The display panel displays the time

2. Set the time with the @ or A sensors.

3. Confirm the time with the 0 sensor.

The programmed time is displayed after a few seconds.

Programming the oven

There are different ways to programme the oven. Programming the type of heating, temperature or grill power. The oven can be programmed with the cooking time (duration) and the end time for each dish. For more information, see the chapter Setting the time functions.
Note: We recommend preheating the oven before inserting the food in order to avoid condensation on the oven glass.

Type of heating and temperature

Example in the picture: top and bottom heat % at 190 °C.

1. Select the type of heating using the function control knob.

Heating the oven

To remove the "new" smell, heat the oven empty with the door closed. The most effective option is to heat the oven for one hour with the top and bottom heating elements 240 ºC. Check that no packaging has been left inside the oven.
1. Select top and bottom heating % using the function control
knob.
2. Press the @ sensor until 240 ºC is displayed on the display
panel.
Turn the oven off after one hour. To do this, turn the function control knob to zero.
