Safety instructions regarding installation, operation, cleaning and maintenance

The ventilation unit may only be installed, set up, retrofitted, commissioned, cleaned, maintained or repaired by installers specialised in ventilation technology. Electrical connection, commissioning, maintenance and repairs may only be carried out by a qualified electrician in accordance with DGUV regulation 3, Section 2 (3) and in compliance with the relevant standards (e.g. DIN EN 50110-1) and technical rules. Further provisions of other national laws must be taken into account.

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 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).

Danger of electric shock from operating the unit when not fully mounted.

Electric components are a potential source of electric shock.

  1. 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.
  2. Only operate the unit when it is completely installed.

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

  1. Before removing the housing cover or removing the fan insert and before installing the electrics, switch off all supply circuits, switch of mains fuse and secure it against being accidentally switched back on again. 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. Unit may be energized even when at a standstill and may switch on automatically due to sensors (time delay, humidity etc.). Maintenance and fault finding only permissible when carried out by qualified electricians.
  4. 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 stepped grommet (The grommet must completely enclose the cable sheathing). The fan insert must also be engaged and the housing cover installed.

Danger of injury due to sharp edges on sheet metal/break-outs in the housing or in the electronics compartment.

Wear protective gloves if necessary. Carefully guide connecting cables into unit. Do not damage cables.

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. 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. Regularly change air filter when a filter change is indicated (LED or TimeStrip).
  4. 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 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 unit to distribute chemicals or aggressive gases/vapours.

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 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 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.

Exercise caution when handling packaging materials.

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