2. Product information

The device provides additional functions for the cooker hood.

The wall box opens when the cooker hood is operated. Once the cooker hood is switched off, the wall box closes after a short delay.

When the wall box is closed, the exhaust air duct is sealed and is insulated against sound and heat.

Observe the cooker hood's instructions.

2.1 Product variants

• BMK-F (remote-controlled – extracted air mode) The device receives a signal from the manufacturer's cooker hood.
• BMK-L (air-controlled – extracted air mode) The device receives a signal from a flow detector in sensor tube. The device can be used for cooker hoods from different manufacturers.
• BMK-Z (remote-controlled – inlet air mode) The device receives a signal from the manufacturer's cooker hood. The device can be used in conjunction with the BMK-F or the BMK-L as an alternative to the window contact switch. The "reed switch" retrofit kit is required if the device is connected to the BMK-L variant.

3. Installation

3.1 Safety information for installation

⚠ WARNING!

Hazard through disregard of the installation instructions!

This chapter contains important information for the safe installation of the device.

Read through this chapter carefully before installing the device.
Follow the safety instructions.
Carry out the installation as described.

• Installation only by qualified specialist personnel.
→ "1.2 Authorised target groups" (page 76).

- Electrical work only to be undertaken by qualified electricians.

→ "1.2 Authorised target groups" (page 76).

- When working at heights, ensure good stable footing (e.g. stable stepladder).

- Store the film or other parts of the packaging in a location which is inaccessible to children.

- The device must be in an undamaged and fault-free condition prior to installation.

• Cables must not be kinked, crushed or damaged.

- It is not permissible to attach further components (e.g. panels, air ducts) to the device.

- The power supply voltage must match the voltage information quoted on the ratings plate.

→ "2.4 Technical data" (page 78).

- Ensure that the power supply is stable and remains so prior to the installation.

Connect the power supply only when instructed to do so in the installation instructions.

3.2 Requirements for the installation location

⚠ WARNING!

Risk of death due to improper installation!

Disregard of the ambient conditions can lead to hazardous situations, e.g. in the handling of electrical power or gas.

Make sure that the requirements for the installation location are complied with.

• Do not install in potentially explosive atmospheres.
• In extracted air mode and whilst using a heating point which uses air from the room as its oxygen supply (e.g. chimney):
  • A safety device is absolutely essential.
• The safety device must prevent gases being drawing to the room.
• It is essential to ensure that the negative pressure in the heating point installation room does not exceed 4 Pa.
• An approval for commissioning (e.g. from a chimneysweep) must be available.

• Installation is only permitted on structural building elements capable of bearing the load (solid structure).

• Installation is only permitted on vertical outside walls.

- Suitable fastening materials must be used if the outside wall is insulated.

- Make sure that the building electrical supply is properly earthed.

- The power supply voltage present must match the voltage information quoted on the ratings plate.

- Inside the building, there must be a max. distance of 1 m between the device and a 230 V socket.

- The air flowing out must be able to dissipate unimpeded. Do not impede the air flow, e.g. through the installation of objects on or above the device.

Country-specific, legal provisions must be observed.

3.3 Requirements for the wall duct:

⚠ WARNING!

Risk of death due to improper installation!

A wall break-through influences the structural integrity of the building. There is a danger of collapse. This work must only be carried out by a specialist.

Make sure that the wall duct is established properly.

ATTENTION!

Danger of property damage due to improper installation! If the angle of the wall duct is incorrect, water can flow inside and cause damage.

Make sure that the wall duct is angled 1-2° outwards.

3.4 Requirements for the exhaust air duct

⚠ WARNING!

Fire hazard and asphyxiation hazard due to improper installation!

When using the exhaust air ducting with other devices or when connecting an active exhaust air channel (e.g. chimney), gases or smoke can be drawn into the room.

Make sure that the requirements for the exhaust air ducting are complied with.

• The exhaust air ducting is used exclusively by this device.
- The exhaust air ducting is made of non-combustible material in accordance with DIN 4102 class B2.
- When routing the exhaust air ducting through the outside wall:
- The cross-section must not be smaller than that of the fan outlet.
- Installation of condensed water collector in the exhaust air ducting in order to prevent water damage inside the device. The condensed water collector must be adequately dimensioned.
- Adequate fresh air supply is assured through the installation of the necessary accessories (e.g. window contact switch).

The cross-section, length, type and course of the exhaust pipe affect the extraction efficiency. Changing the direction of the air too severely leads to a loss of performance and to noise.

To optimise the device performance:

• Keep the exhaust air ducting as short as possible and route it directly to the outside.
• The stipulated cross-section of the exhaust air ducting is complied with.
• Exclusive use of ducts and bends with smooth inner surfaces.

In order to avoid turbulence or backpressure in the transported air - do not use:

• Spiral hoses.
• Flexible tubes.
• Flat deflection pieces.
  • Sharp-edged exhaust air channels.
