Safety

DANGER 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.

WARNING 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.

DANGER 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. A mains isolation device with contact openings of at least 3 mm at each pole is mandatory.
  4. Only connect unit to permanent electrical installation and with NYM-O or NYM-J cables, depending on the unit variant, 4x 1.5...4 mm².
  5. Units 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 switch on automatically due to sensors (time delay, humidity etc.). Maintenance and fault finding only permissible when carried out by qualified electricians.
  7. The degree of protection stated on the rating plate is only guaranteed if installation is undertaken correctly and if the connection 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 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.

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

Ensure that foreign bodies cannot be sucked into the unit and ducts. For fans with a free inlet, fit a protective grille (e.g. SG .../ SGR ...). The unit can only be operated if protection against accidental contact with the impeller is guaranteed in accordance with DIN EN ISO 13857.

WARNING 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.

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

Do not insert any objects in the unit.

WARNING 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.

Specialist installers, qualifications, requirements

The fan may only be installed, set up, retrofitted, commissioned, cleaned, serviced 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.

Qualifications, requirements: Specialist training and knowledge of compulsory technical standards, EU Directives and EU Ordinances. The installations must be carried out professionally. Applicable accident prevention regulations, occupational health and safety measures (protective clothing in good repair etc.) must be observed. Installation work by trainees is only permitted under the supervision of the above-mentioned trained specialists.
