Safety instructions regarding installation, operation, cleaning and maintenance

Risks for children and people with reduced physical, sensory or mental capabilities or a lack of knowledge.

  1. Unit may only be installed, commissioned, cleaned and maintained by persons who can safely recognise and avoid the risks associated with this work.

Risk of injury due to suction from unit and rotating impeller.

Hair, clothing, jewellery etc. may be pulled into the unit if you get too close to it.

  1. During operation, always keep far enough away to prevent this from happening.

Risk of injury if foreign objects are inserted into the unit.

Do not insert any objects in the unit.

A fan that is not installed correctly may result in non-intended operation or impermissible operation.

Operation is only permitted with a correct installation position (see TOP on unit), with mounted design cover and outer protective grille.

  1. The fan may be operated only if the protection against accidental contact with the impeller is guaranteed to be in accordance with DIN EN ISO 13857.

Risk of injury and health risk in the event of changes or modifications or if components which are not permitted are used.

The unit may only be operated with original components. Changes and modifications to the units are not permitted and release the manufacturer from any guarantee obligations and liability, e. g. if the housing is drilled at a point which is not permitted.

Risk of injury when working at heights.

  1. Use appropriate climbing aids (ladders).
  2. Stability should be ensured, if necessary have the ladders steadied by a 2nd person.
  3. Ensure that you are standing securely and cannot lose your balance and that there is no one under the unit.

Risk of death from carbon monoxide when operating with air-ventilated fireplaces.

The maximum permitted pressure difference per residential unit is 4 Pa. The consent of a professional chimney sweep is needed in all cases.

  1. Ensure sufficient supply air intake during operation with an air-ventilated fireplace.

Danger of electric shock when operating a fan which is damaged or not fully mounted.

Before taking off the electronics cover, shut down all supply circuits (switch off mains fuse), secure against being accidentally switched back on and position a visible warning sign.

  1. Only operate the fan when it is completely installed.
  2. Do not commission a damaged unit.

Danger if the relevant regulations for electrical installations are not observed.

  1. Before installing the electrics, shut down all supply circuits, deactivate the mains fuse and secure it so it cannot be switched back on. Attach a warning sign in a clearly visible place.
  2. Be sure to observe the relevant regulations for electrical installation; e.g. DIN EN 50110-1. In Germany, particularly observe VDE 0100, with the corresponding sections.
  3. A mains isolation device with contact openings of at least 3 mm at each pole is mandatory.
  4. Only connect unit to permanently wired electrical installation and with NYM-O or NYM-J cables, depending on the unit type, 3 x 1.5 mm² or 5 x 1.5 mm².
  5. The unit may only be operated using the voltage and frequency shown on the rating plate.
  6. Unit may be energized even when at a standstill and may be started up automatically by sensors, such as those for time delay or humidity etc.
  7. The degree of protection stated on the rating plate is only guaranteed if installation is undertaken correctly and if the connecting cable is correctly guided through the cable grommet. The grommet must tightly seal the cable sheathing.

With protection class I, connect the PE conductor and check the connection.

Exercise caution when handling packaging materials.

  1. Observe applicable safety and accident prevention regulations.
  2. Store packaging material out of the reach of children (risk of suffocation due to swallowing).

Supply air intake within the living area
