Installation Guide for Miele KMDA 7473 Series Cooktops

Safety Instructions for Installation

⚠️ Damage due to improper installation.

Improper installation can damage the cooktop. Have the cooktop installed only by a qualified professional.

⚠️ Risk of electric shock from mains voltage.

Improper connection to the electrical network can cause electric shock. Have the cooktop connected to the electrical network only by a qualified electrician.

⚠️ Damage from falling objects.

The cooktop can be damaged during the installation of overhead cabinets or an extractor hood. Install the cooktop only after the overhead cabinets and extractor hood have been mounted.

Worktop veneers must be processed with heat-resistant adhesive (100 °C) to prevent them from loosening or deforming. Wall trim strips must be heat-resistant.

The cooktop must not be installed above refrigerators, dishwashers, washing machines, or dryers.

No gas hob may be installed next to this cooktop.

This cooktop may only be installed above ovens equipped with a vapor cooling system.

Ensure that the mains connection cable cannot be touched after the cooktop has been installed.

After installation, the mains connection cable must not come into contact with moving parts of kitchen elements (e.g., a drawer) and must not be exposed to mechanical stress.

Observe the safety clearances specified on the following pages.

Ventilation Ducting Requirements

Only use pipes or hoses made of non-combustible material for routing the exhaust duct. These are available from specialist retailers or customer service.

The exhaust air must not be routed into a used smoke or exhaust gas chimney, nor into a shaft used for ventilating rooms with fireplaces.

If the exhaust air is to be routed into an unused smoke or exhaust gas chimney, observe the official regulations.

In Plug&Play mode, the extracted air may only be routed back into the room via the base cabinet. In exhaust mode and ducted recirculated air mode, the exhaust air must be routed outside (exhaust mode) or back into the room via the recirculation box (ducted recirculated air mode).

Safety Clearances

Clearance Above the Cooktop

The safety clearance specified by the hood manufacturer must be observed between the cooktop and an extractor hood installed above it.

If flammable materials (e.g., a shelf) are installed above the cooktop, the safety clearance must be at least 500 mm.

If multiple appliances with different clearance requirements are installed under an extractor hood, maintain the greatest required clearance.

Rear and Side Safety Clearances

Preferably, install the cooktop with ample space to the right and left.

A minimum clearance (1) must be maintained at the rear of the cooktop to a tall cabinet or wall.

On one side of the cooktop (right or left), a minimum clearance (2, 3) must be maintained to a tall cabinet or wall, with a clearance of 200 mm on the opposite side.

• (1) Minimum rear clearance from worktop cut-out to the rear edge of the worktop: 50 mm.
• (2) Minimum right-side clearance from worktop cut-out to an adjacent piece of furniture (e.g., tall cabinet) or wall: 50 mm.
• (3) Minimum left-side clearance from worktop cut-out to an adjacent piece of furniture (e.g., tall cabinet) or wall: 50 mm.

Diagrams illustrate forbidden, highly recommended, and not recommended installation configurations based on clearances.

Clearance to Niche Cladding

When niche cladding is installed, a minimum clearance must be maintained between the worktop cut-out and the cladding to prevent high temperatures from altering or damaging materials.

• For cladding made of combustible material (e.g., wood), the minimum clearance is 50 mm.
• For cladding made of non-combustible material (e.g., metal, natural stone, ceramic tiles), the minimum clearance is 50 mm minus the thickness of the cladding. Example: Cladding thickness 15 mm results in a 35 mm minimum clearance (50 mm - 15 mm).

Diagrams show cross-sections for flush-mounted and surface-mounted installations, indicating clearances relative to niche cladding and worktop cut-outs.

Operating Possibilities

The following table outlines the operating modes available for different models:

Key: ✓ Possible; ✓✓ Possible - additional accessories required; - Programming must be changed - additional accessories required.

Installation Notes

Surface-Mounted Installation

Seal between Cooktop and Worktop:

⚠️ Damage from incorrect installation.

Using joint sealant can damage the cooktop and worktop during removal. Do not use joint sealant between the cooktop and worktop. The seal under the cooktop edge ensures adequate sealing to the worktop.

The joint and the hatched area under the cooktop's support surface must be smooth and level for even seating and proper sealing.

Sealing Tape:

If the cooktop is removed for servicing, the sealing tape under its edge may be damaged. Always replace the sealing tape before reinstallation.

Follow these steps for surface-mounted installation:

• Create the worktop cut-out, observing safety clearances.
• Shorten the drilling template to your worktop thickness. Place the template on the cabinet rear wall according to installation depth and create the cut-out for the air duct or Plug&Play adapter. If the template is missing, refer to the "Rear Wall Cut-out - without Drilling Template" section.
• Seal cut edges on wooden worktops with special lacquer, silicone rubber, or resin to prevent moisture-induced swelling. The sealing material must be temperature-resistant. Ensure these materials do not get onto the worktop surface.
• Adhere the supplied sealing tape under the cooktop edge. Do not stretch the sealing tape when applying.
• Important: The Plug&Play adapter can break. Place the cooktop on the worktop so the Plug&Play adapter is not resting on it.
• Route the cooktop's mains connection cable downwards through the worktop cut-out.
• Plug&Play Operation: Remove the protective film from the adhesive tape on the Plug&Play adapter.
• Place the cooktop centrally in the cut-out. Ensure the seal on the worktop is seated correctly to guarantee sealing.
• Never use additional joint sealant (e.g., silicone) for sealing.
• If the seal at the corners is not seated correctly, carefully adjust the corner radii (≤ R4) with a jigsaw.
• Plug&Play Operation: Align the Plug&Play adapter with the pre-drilled hole. Press the adapter onto the rear wall until it adheres.
• Connect the cooktop to the mains.
• Check the cooktop's function.

Flush-Mounted Installation

Flush-mounted installation is suitable for natural stone (granite, marble), solid wood, and tiled worktops. Cooktops marked for flush-mounting are also suitable for glass worktops. For other worktop materials, consult the manufacturer.

The clear width of the base cabinet must be at least as wide as the internal worktop cut-out to ensure the cooktop is accessible from below for maintenance. If the cooktop is not accessible from below, sealant must be removed for removal.

• Natural Stone Worktops: The cooktop is inserted directly into the milled recess.
• Solid Wood, Tiled, Glass Worktops: The cooktop is secured in the cut-out with wooden strips (not included, must be supplied by installer).
• Sealing Tape: If the cooktop is removed for servicing, the sealing tape may be damaged. Always replace it before reinstallation.

For flush-mounted installation, ensure the gap between the ceramic glass and the worktop is at least 2 mm wide for proper sealing.

⚠️ Damage from unsuitable sealant.

Unsuitable sealant can damage natural stone. For natural stone and natural stone tiles, use only sealant suitable for natural stone. Follow the manufacturer's instructions.

Cabinet Integration and Clearances

Cabinet Rear Wall (Exhaust & Ducted Recirculated Air): The rear cabinet wall must be removable for servicing. Route the air duct between the cabinet wall and adjacent furniture/wall with a minimum clearance of 110 mm.

Drip Tray and Cleaning Flap: Ensure these are accessible after installation.

Minimum Plinth Height:

• For Ducted Recirculated Air Operation: 100 mm
• For Plug&Play Operation: 25 mm

Ventilation Opening Cross-section (Plug&Play): Must be at least 425 cm². If using grilles, the opening must be larger. Ensure openings are not obstructed and are cleaned regularly.

Traverse Removal (Plug&Play): Remove cross members above the cabinet rear wall for Plug&Play adapter installation.

Drilling Template: A template is required for cooktop installation.

Further U-value information is available on government websites. Consult a building surveyor or energy consultant for assistance.

Connection to Window Contact (if required)

⚠️ The connection for the window contact is live. Risk of electric shock.

Disconnect the cooktop from the mains before connecting the switching system. The connection must be made by a qualified electrician.

The connection cable must be H03VV-F 2x0.75 mm² and a maximum of 2.0 m long. The switching system requires a potential-free closing contact suitable for 230 V, 1A. When open, the extractor hood is deactivated.

Use only DIBt-approved and tested radio switching systems (e.g., window contact switches, negative pressure monitors) and have them approved by authorized personnel (certified chimney sweep).

Refer to the external switching system's documentation for safe connection and operation.

Procedure:

• Release the retaining clip and pull out the plug.
• Loosen screws (1) of the strain relief and unlatch the housing on both sides (2).
• Open the housing.
• Remove the plug.
• Replace the bridge (1) with the switching system's connection cable.
• Close the housing.
• Retighten the strain relief screw.
• Reinsert the plug.

Electrical Connection

⚠️ Damage from improper connection.

Improper installation, maintenance, or repairs can pose significant risks. Miele is not liable for damage resulting from improper work or a missing/interrupted protective earth conductor.

Have the cooktop connected to the mains by a qualified electrician who is familiar with and adheres to local regulations and power company requirements.

Ensure touch protection for operationally insulated parts after installation.

Total Power: Refer to the type plate.

Connection Data: Find required connection data on the type plate; it must match the mains supply. Connection possibilities are shown in the connection diagram.

Residual Current Device (RCD): For safety, an RCD with a 30 mA tripping current is recommended.

Disconnection Devices: The cooktop must be disconnectable from the mains in all poles. A contact gap of at least 3 mm is required when disconnected. These devices serve as overcurrent protection and circuit breakers.

Disconnecting from the Mains

⚠️ Risk of electric shock from mains voltage.

Ensure the mains are secured against re-switching during repair/maintenance. To disconnect the circuit:

• Cartridge Fuses: Remove fuse inserts completely.
• Screw-in Fuse Holders: Press the red test button until the black center button pops out.
• Built-in Circuit Breakers (Type B or C): Set the toggle lever from 1 (On) to 0 (Off).
• RCD: Switch the main switch from 1 (On) to 0 (Off) or press the test button.

Mains Connection Cable

Connect the cooktop using a H 05 VV-F (PVC-insulated) cable with suitable cross-section, as per the connection diagram. Permissible voltage and connection value are on the type plate.

⚠️ Risk of electric shock from mains voltage.

Improper connection can cause electric shock. Have the mains connection cable changed only by a qualified electrician. Use only the specified H 05 VV-F cable type. The cable is available from the manufacturer or customer service.

Connection Diagram

Not all connection possibilities are permitted. Observe local regulations and power company requirements.

Diagrams illustrate different connection types (e.g., single-phase, two-phase, three-phase) showing terminal assignments (L1, L2, L3, N) and voltage levels.

Exhaust Ducting

⚠️ Risk of poisoning!

Simultaneous operation of the extractor hood and a room-air-dependent fireplace may pose a risk of poisoning. Strictly observe the "Safety Instructions and Warnings" chapter. In case of doubt, have safe operation confirmed by the responsible chimney sweep master.

The extractor hood has an exhaust connection of Ø 150 mm.

Use only smooth pipes or flexible exhaust hoses made of non-combustible material.

To achieve maximum airflow and low operating noise:

• The exhaust duct cross-section must not be smaller than the exhaust spigot's cross-section.
• The exhaust duct should be as short and straight as possible.
• Use only bends with large radii.
• The exhaust duct must not be kinked or crushed.
• Ensure all connections are firm and leak-proof.

Note that airflow restrictions increase noise and reduce performance.

• If routing into an exhaust chimney, direct the insertion spigot in the direction of flow.
• For horizontal ducting, maintain a gradient to prevent condensate from flowing into the fan.
• If routing through cool rooms, condensate may form, requiring insulation of the exhaust duct.
