4 Installation

▶ Observe all safety and warning information (see "2 Safety").
▶ Follow the enclosed manufacturer's information.

4.1 General installation instructions

The appliance must not be installed above cooling devices, dishwashers, stoves, ovens, washing machines or dryers.
The contact surfaces of the worktops and wall sealing strips must be made of a heat-resistant material (up to approx. 100 °C).
Worktop cut-outs must be moisture-sealed using suitable means and, where necessary, fitted with a thermal insulator.
External devices may only be connected to the cooktop extractor connections provided.
i Extremely bright lights aimed directly at the appliances can cause colour variations in the appliances and are thus to be avoided.
All packaging must be removed before using the appliance for the first time.

General installation instructions for cooktops

▶ Make sure that the area below the cooktop has a sufficient air supply.
To maintain the level of performance, sufficient ventilation below cooktops must be ensured.
The performance is affected or the cooktops overheat if the warm air beneath the cooktops cannot escape.
In the event of overheating, the cooktop power is reduced or the appliance is switched off completely.
If cable protection (false floor) is planned beneath the appliance, this must be fitted so it does not obstruct ventilation.

Additional installation instructions for Australia and New Zealand (AU/NZ):

The gas hose must be checked every 5 years and replaced if necessary. The gas hose must meet the requirements of AS/NZS 1869.

Restricted functions when using the cooktops without a cooktop extractor

If cooktops are installed and operated without a cooktop extractor, only limited functions will be available. The following functions will not be available:

- System functions

• Pause function
• Short-time timer
• Child lock

- All settings/functions in the configuration menu

4.1.1 Operating the cooktop extractor in the exhaust air mode and where there is a fireplace dependent upon the air supply in the room

National and regional laws and regulations must be observed with regard to the exhaust duct design.

A sufficient air supply must be ensured.

Fireplaces that depend on the air in the room (e.g. gas, oil, wood or coal-fired heaters, continuous-flow water heaters, instantaneous water heaters) draw in air from the room in which they are installed and release the exhaust fumes into the outside air via an exhaust system (e.g. chimney).

If the cooktop extractor is used in exhaust air mode, it draws in air from the room in which it is installed as well as from neighbouring rooms. Without sufficient air, there will be a drop in air pressure. Toxic gases could be drawn out of the chimney or extraction ducting and back into the room.

Fig. 4.1 Exhaust air installation – not permitted

Fig. 4.2 Exhaust air installation – correct

▶ If simultaneously operating both a fireplace and the cooktop extractor in the same room, ensure that:
- the maximum low pressure is 4 Pa (4 x 10^-5 bar);
- a safety device (e.g. window contact switch, low pressure warning device) is used to ensure that a sufficient supply of fresh air is guaranteed;
- the exhaust air is not channelled into a chimney that is used for exhaust gases of appliances operated with gas or other combustibles;
- the installation is checked and approved by an authorised certified engineer (e.g. heating engineer).

• when using a window contact switch, only devices will be installed which meet the requirements of standard IEC 60730-1:2013 + AMD1:2015 or EN 60730-1:2016 (or a more recent IEC update or EN standard) for type 2 control units and devices (e.g. window contact switch UFKS).
  No window contact switches may be installed that separate the control unit from the power supply (phase separation). Only the Home In interface is to be used
  If the cooktop extractor is used exclusively in recirculation mode, operation with an open fireplace is possible without any additional safety measures.

▶ Switch on the main switch/automatic circuit breaker.
▶ Put the cooktop into operation (see the operating instructions).
▶ Check that all the functions are working correctly.

4.14 Basic configuration

When installation is complete, you must carry out the basic settings (these settings can be changed at any time later on). You can see precise instructions on the basic configuration and all necessary information in the operating instructions.

4.14.1 Gas configuration

The burner nozzles, gas type and pressure may only be changed by a certified engineer or BORA service technician. They also assume responsibility for the proper gas installation and commissioning.
Gas characteristic curve A must not be used in the case of liquid gas (G30/31).
It is important that the gas type, gas pressure and characteristic curve are set correctly to ensure safe, failure-free operation of the gas cooktop.
You can see detailed information on the configuration menu in the operating instructions.

4.15 Initial operation

▶ Ensure that all appliances are connected correctly and connected to the power supply (fused) prior to initial operation.

• Exception: during initial operation, the kitchen fitter may use a temporary power supply for the control unit in order to configure the appliance (e.g. using the site power supply during the building phase).
• The settings made are saved and will not be affected when the system is disconnected from the mains.
• The final mains connection to the appliances may only be set up by certified specialists.
  ▶ Carry out a thorough function test on all appliances.
  In the event of error messages, see the "Troubleshooting" chapter.

4.15.1 Using the gas cooktop for the first time

Initial operation is possible when the gas cooktop has been fully installed and configured.

Function test on the gas cooktop

▶ Switch the cooking zone on. The electronic gas regulator will calibrate itself (humming noises) and then the gas flame will automatically ignite in the selected cooking zone. The gas flame will burn steadily and evenly.

Using the gas cooktop together with the cooktop extractor for the first time

▶ Switch the cooktop extractor to the maximum power level.

▶ Switch all cooking zones to the minimum power level.

The electronic gas regulator will calibrate itself (humming noises) and then the gas flame will automatically ignite in the selected cooking zone. The gas flame will burn steadily and evenly (no reignition). The gas flame will be slightly affected by the cooktop extractor (airflow) – this is normal.

▶ Carry out a thorough function test on all appliances.

In the event of error messages, see the "Troubleshooting" chapter.

4.16 Sealing the appliances

▶ Once all of the installation work and initial operation is complete, seal the appliances all the way round (also between the cooktop extractor and cooktop) with black, heat-resistant silicone sealant.
▶ Make sure that no silicone sealant gets under the cooktop.

4.17 Handover to user

Once installation is complete:

Explain the main functions to the user.
Explain all safety-related aspects of operation and handling to the user.
▶ Provide the user with the accessories and operating and installation instructions, which are to be kept in a safe place.
▶ Affix the identification plates provided to the penultimate page in the operating instructions.

If a gas cooktop is installed:

▶ also affix the nozzle set identification plate to the penultimate page of the gas cooktop operating instructions.

5 Decommissioning, disassembly and disposal

▶ Observe all safety and warning information (see "2 Safety").
▶ Follow the enclosed manufacturer's information.

5.1 Decommissioning

Decommissioning refers to ultimate decommissioning and disassembly. Following decommissioning, the appliance can either be installed in another unit, sold on privately or disposed of.

The electricity and gas connections may only be disconnected and cut off by certified specialists.

▶ Switch the appliance off before decommissioning (see operating instructions)
▶ Disconnect the appliance from the power supply.
▶ Disconnect the appliance from the gas supply.

5.2 Disassembly

To be removed, the appliance must be accessible for disassembly and disconnected from the power supply.

In the case of gas appliances, it must be ensured that the gas is disconnected.
▶ Remove the appliance fastenings.
▶ Remove the silicone seals.
▶ Disconnect the appliance from the exhaust duct.
▶ Lift the appliance up and out through the top of the worktop.
▶ Remove any other accessories.
▶ Dispose of the old appliance and any soiled accessories as described under “Environmentally-friendly disposal”.

5.3 Environmentally-friendly disposal

5.3.1 Disposal of transport packaging

The packaging protects the appliance from damage during transport. The packaging materials have been selected taking into account the environment and their disposal and are therefore recyclable.

Recycling the packaging saves raw materials and reduces waste. Your specialist retailer will take the packaging back.

▶ Give the packaging to your specialist retailer
or

▶ dispose of the packaging correctly observing regional regulations.

5.3.2 Disposal of accessories

Dispose of unnecessary or used accessories (activated charcoal filters, etc.) accordingly taking into account the regional regulations.

5.3.3 Disposal of the old appliance

Electrical appliances with this mark must not be disposed of in the household waste at the end of their service life. They must be disposed of at a collection point for the recycling of electrical or electronic appliances. Information on this can be obtained from the city or local councils.

Waste electrical and electronic appliances often still contain valuable materials. However, they also contain harmful substances that were necessary to make them work and ensure their safety. If placed in the household waste or handled incorrectly, they may harm human health and damage the environment.

▶ Never dispose of your old appliance in the household waste.
▶ Take the appliance to a regional collection point for the return and further processing of electrical and electronic components and other materials.
