Safety instructions

Read and observe all the safety instructions.

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.

Danger to life in the event of toxic, polluted air (smoke, vapours) in the vicinity – in the event of a fire or chemical accident, etc.

  1. Switch off the entire ventilation system immediately until the outside air is harmless again.

Risk of injury in case of damaged unit.

  1. Switch the unit off immediately if you discover damage or faults that could endanger persons or property.
  2. Prevent from being switched back on until fully repaired.

Risk from operating with ventilation unit not fully installed (open unit / without ventilation ducts).

Running fans can be touched. Electric components are a potential source of electric shock.

Risk of burns on units with a heat register.

If the unit is open, all off the supply circuits must be switched off (mains fuse off), secured against being accidentally switched back on and a visible warning sign must be attached.

  1. Only operate unit if fully installed, if all ventilation ducts are attached and the front doors are closed.
  2. Do not reach into running fans.
  3. The heat register and/or protective grilles of the heat register may be very hot. Before touching, check whether heat registers and/or protective grilles are still hot. Do not touch hot surfaces.

Danger of electric shock.

  1. Before opening the front doors and installing the electrics, switch off all supply circuits, switch off the mains fuse and secure against being accidentally switched back on again.
  2. Attach a warning sign in a clearly visible place.

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

  1. Before removing the electronics cover and installing the electrics, switch off all supply circuits, switch off the mains fuse and secure against being accidentally switched back on again.
  2. Attach a warning sign in a clearly visible place.
  3. 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.
  4. A mains isolation device with contact openings of at least 3 mm at each pole is mandatory.
  5. Only connect the ventilation unit to a permanent electrical installation.
  6. Units may only be operated using the voltage and frequency shown on the rating plate.

Risk of death when operating with air-ventilated fireplaces.

  1. Ensure sufficient supply air intake during operation with air-ventilated fireplaces.
  2. Note maximum permissible pressure difference per residential unit. This model always requires the approval of a regional master chimney sweep. Ventilation units may only be installed in rooms, apartments or housing units of a comparable size, in which air-ventilated fireplaces are installed if:
  3. – a parallel operation of air-ventilated fireplaces for liquid or gaseous fuels and the air-extracting equipment can be prevented via safety devices, or
  4. – the extraction of exhaust gas from the air-ventilated fireplaces is monitored by special safety devices. In the case of air-ventilated fireplaces for liquid or gaseous fuels, the fireplace or the ventilation system must be switched off if the safety device is triggered. In the case of air-ventilated fireplaces for solid fuels, the ventilation system must be switched off if the safety device is triggered. In order to permit the intended operation of ventilation systems equipped with the central ventilation units with heat recovery, it must be possible to shut off any combustion air ducts or exhaust gas ducts from air-ventilated fireplaces. For exhaust gas ducts of fireplaces for solid fuels, the shut-off device may only be operated by hand. It must be possible to identify the position of the shut-off device from the setting of the operating handle. This is considered to be fulfilled if a soot blocking device is used.

Risk from inadequate load-bearing capacity of the surface/ceiling construction.

Only install ventilation unit on a surface/ceiling construction with an installation/attachment surface with an adequate load-bearing capacity (at least 300 kg/m²).

Risk during transport from heavy or falling loads.

  1. Observe applicable safety and accident prevention regulations.
  2. Do not stand under a suspended load.
  3. Note permissible maximum loading capacity of lifting gear.
  4. Exercise caution when lifting. Note transport weight and centre of gravity (centre) of ventilation unit.
  5. Only transport unit to installation site using suitable transport equipment (e.g. a lifting device) and with the help of several people.
  6. Check unit for transport damage. Do not commission a damaged unit.

Risk of injury and risk to health from parts which may affect the ventilation system which are added or modified at a later date.

Parts (range hood, air-ventilated fireplace etc.) which are added or modified at a later date may result in health risks and operation which is not permitted. Parts may only be added or modified at a later date if system compatibility is established/ensured by a planning office. If using an exhaust air range hood or air-ventilated fireplace, this must be accepted by a regional master chimney sweep.

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 injury if unit components (heat register, heat exchanger etc.) fall down during removal. Sometimes these can be hard to pull out/slide in.

  1. Ensure that you are standing securely and cannot lose your balance and that there is no one under the unit.
  2. When removing and installing the components, support them from below with a hand.

Risk of injury and health risk when using accessory elements which have not been approved.

The unit is tested with original accessory components (e.g. air filter, heat register, heat exchanger).

  1. The unit may only be operated with original components.
  2. Modifications and alterations to units are not permitted and release the manufacturer from any guarantee obligations and liability.

Risk to health if filters are not replaced or if there are no air filters.

Heavily soiled or moist air filters can accumulate harmful substances (mould, germs, etc.). This may also happen if the unit is shut down for an extended period. If the air filter is missing, the unit and air ducts become soiled.

  1. Never operate the unit without air filters.
  2. Only use original filters.
  3. Recommendation: Continuous operation.
  4. Observe filter change display. Change the air filter every 6 months.
  5. If the unit has not been used for a long time, always replace the air filters.

Risk to health if unit is not correctly cleaned.

  1. Clean the unit regularly, at least every 2 years. This is the only way of ensuring that the unit is running hygienically.

Risk of injury from handling pointed housing parts or those with sharp edges, e.g. on housing panels, railings, mounting feet or pointed parts of front doors.

  1. Wear protective gloves.

Risk of injury if work is carried out by unqualified staff.

Specialist knowledge is needed for the safe transport, installation, electrical connection and commissioning of the ventilation unit.

  1. Only have this work carried out by a specialist installer or qualified electrician.

Exercise caution when handling packaging materials.

  1. Store packaging material out of the reach of children (risk of suffocation due to swallowing).

Intended operation not ensured if installed incorrectly.

A ventilation unit not installed correctly may result in operation not as intended.

  1. Only install ventilation unit in accordance with the planning documents.
  2. In particular, note the information on insulating ventilation channels and sound deadening. Recommendation: Use tubular sound absorber for sound-deadened installation of ventilation unit.

Damage to unit in the event of moisture ingress.

The unit has degree of protection IP 44.
