Lighting

The operating panel has 2 different levels of lighting (100% and 50%).

On principle the system adapts the lighting to the current operating scenario. Relevant display elements are more brightly lit and irrelevant ones are dimmed. Unavailable functions are faded out.

Lighting	Use
100%	Function is active and selected
50%	Function is inactive but can be selected
0% (no indicator) - Function is unavailable

Tab.4 Lighting

Sounds

The volume of the acoustic signals can be set in the menu (0% to 100%).

The acoustic signal for the power button cannot be set to 0.

Safety-relevant acoustic signals are always emitted with the volume at 100%.

The system basically differentiates between two different types of acoustic signals:

Acoustic signal	Purpose
Short individual beep (0.1 s)	Confirmation of a selection
Sequence of beeps	Interaction required

Tab.5 Sounds

How the cooktop extractor works

Depending on the model you purchased, the cooktop extractor can be operated as an exhaust air or a recirculating air version.

Exhaust air mode

The air suctioned away is purified by the grease filter and expelled into the open air via a duct system. The exhaust air must not be expelled into:

• a smoke or exhaust gas flue that is in operation
• a shaft used for the aeration of rooms where fireplaces are installed.

If the exhaust air is to be directed into a smoke or exhaust gas flue that is not in use, the installation must be checked and approved by the responsible heating engineer.

Recirculation mode

The air suctioned away is purified by the grease filter and an activated charcoal filter and fed back into the room in which the appliance is installed. To prevent odours in recirculation mode, an odour filter must be used.
For health and hygiene reasons, the activated charcoal filter must be replaced at the recommended intervals (see "Cleaning and maintenance" ).

In recirculation mode, ensure sufficient ventilation and aeration to expel humidity.

How the induction cooktop works

An induction coil is located underneath an induction cooking zone. If the cooking zone is switched on, this coil creates a magnetic field that acts directly on the base of the pot thus heating it up. The cooking zone is only indirectly heated up by the heat emitted by the pot. Cooking zones with induction only work if the cookware has a magnetisable base. Induction automatically takes into account the size of the cookware used which means that only the area in the cooking zone covered by the base of the pot is heated up.

Suitable cookware

The heating and heat-through times for the cookware base, as well as the cooking results, are significantly influenced by the structure and material of the cookware.

Cookware with this symbol is suitable for induction cooktops. The cookware used for the induction cooktop must be made of metal, feature magnetic properties and possess an ample base.

Suitable cookware is made of:

• stainless steel with a magnetisable base
• enamelled steel
• cast iron
  • Perform a magnet test, if necessary. If a magnet sticks to the base of the utensils, they are normally induction compatible.
  • Pay attention to the cookware base. The bottom of the cookware should not show any sign of curvature. Due to incorrect hob temperature monitoring, this curvature may cause the cookware to overheat. To avoid scratching the cooktop, the base of the cookware must not have any sharp grooves or sharp edges.
  • Place the cookware (without a mat or similar) directly onto the glass ceramic.
  • Observe the minimum pot base diameter.

Appliance	Cooking zone	Minimum diameter of cookware base
PUXA	front rear	120 mm 120 mm
PUXU	front rear	120 mm 120 mm
PURA	front rear	120 mm 90 mm
PURU	front rear	120 mm 90 mm

Tab.6 Minimum cookware diameter

Noises

The following noises may occur in the cookware when using induction cooking zones, depending on the material and the finish of the base:

• Humming may occur when using a high power level. This decreases or disappears when the power level is decreased.
• Crackling or whistling may occur due to the bases of cookware being made of different materials (e.g. sandwich base).
• Clicking sounds may occur during electronic switching procedures, especially at low power levels.
• Whirring may occur when the cooling fan is switched on. In order to increase the service life of the electronic system, the cooktop is equipped with a cooling fan. The cooling fan switches on automatically if the cooktop is used intensively. You will hear a whirring sound. The cooling fan may continue to run after the appliance has been switched off.
