Safety instructions

The external shutter must not be used in the following situations under any circumstances.

Risk of combustion/fire from flammable materials, liquids or gases in the vicinity of the unit.

  1. Do not place any flammable materials, liquids or gases near the unit, which may ignite in the event of heat or sparks and catch fire.

Explosion hazard due to gases and dust.

Explosive gases and dust may ignite and cause serious explosions or fire.

  1. Never use unit in an explosive atmosphere (risk of explosion).

Risk to health from chemicals or aggressive gases/vapours.

Chemicals or aggressive gases/vapours may harm health, especially if they are distributed throughout the rooms by the unit.

  1. Never use the unit as a duct shutter for chemicals or aggressive gases/vapours.

Damage to unit due to grease and oil vapours from range hoods.

Grease and oil vapours from range hoods may contaminate the unit and reduce efficiency.

  1. Never use external shutter in combination with range hoods with exhaust air mode.

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 effect and rotating impeller of a connected fan.

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 due to spark formation if foreign bodies are inserted into the unit.

  1. Do not insert any objects in the unit.

An external shutter that is not installed correctly may result in non-intended operation or impermissible operation.

Operation is only permitted if installed in the correct installation position (Maico logo at bottom right).

Risk of injury in entrance areas when ice forms due to falling icicles.

  1. Never install the shutter above entrance areas that are not covered.

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.

Depending on type, sound power level up to 66 dB(A).

  1. When planning, take into account sound insulation at the installation site.

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.

Risk of electric shock if operated with a damaged external shutter.

  1. Only operate the external shutter 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 variant, 3 x 1.5 mm² or 5 x 1.5 mm².
  5. Units may only be operated using the voltage and frequency shown on the rating plate.
  6. The degree of protection stated on the rating plate is only guaranteed if installation is undertaken correctly and if the connection cable is properly attached.
  7. Unit may be energized even when at a standstill and may be switched on automatically by sensors, such as for time delay or humidity etc. Maintenance and fault finding only permissible when carried out by qualified electricians

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).
