Safety instructions

Please read the instructions carefully before installing and using for the first time. Follow the instructions. Pass these instructions on to the owner for safekeeping.

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.

Risk of combustion/fire from flammable materials, liquids or gases in the vicinity of the fan. Do not place any flammable materials, liquids or gases near the fan, which may ignite in the event of heat or sparks and catch fire.
Attention: Damage to unit due to steam-saturated or greasy air or adhering solid particles. Steam-saturated or greasy air or solid particles which may adhere to the unit, can soil the unit and reduce the efficiency. Never use fan to convey these substances.
Danger: Explosive gases and dust may ignite and cause serious explosions or fire. Never use fan 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. Never use fan to distribute chemicals or aggressive gases/vapours.

Risk of death from carbon monoxide when operating with air-ventilated fireplaces. Ensure sufficient supply air intake when operating with air-ventilated fireplaces. Observe the maximum permitted pressure difference of 4 Pa. This model always requires the approval of a regional master chimney sweep.

Risks for children and people with reduced physical, sensory or mental capabilities or a lack of knowledge. Fan may only be installed, commissioned, cleaned and maintained by persons who can safely recognise and avoid the risks associated with this work.

Choking hazard if packaging materials are swallowed. Keep foil materials and small parts away from children.

Risk of injury due to suction from the unit and rotating impeller. Hair, clothing, jewellery etc. may be pulled into the unit if you get too close to the fan. Keep sufficient distance during operation. Do not insert any objects into the fan.
Health risk due to deposits on the unit (mould, bacteria, dust etc.) after the fan has not been used for a long time. Clean fan at regular intervals, especially after the fan has not been used for a long time.
Attention: A fan that is not mounted correctly may result in non-intended operation or impermissible operation. Ensure that foreign objects cannot be drawn into the fan and ducts. With a free inlet, fit a protective grille (e.g. SG ../ SGR .. protective grille). 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 risk to health 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 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.

Fan does not satisfy standard DIN 18017-3 for single air extraction systems. Do not use in systems in accordance with DIN 18017-3.

Never operate the fan during the construction phase. Fan and ducting can become dirty and damage the fan.

Use personal protective equipment (protective clothing, hard hat, protective goggles, etc.) for your own protection in the event of possible hazards. Pay attention to the applicable safety and accident prevention regulations.

When working at heights, use suitable ladders/climbing aids and ensure that they are stable. Ensure that you are standing securely and cannot lose your balance and that there is no one under the unit. The applicable accident prevention regulations must be observed. Assembly areas must be secured against unauthorised entry, falling objects and falling.

Switch the fan off immediately if it is damaged, especially if you notice damage or faults that endanger persons or property. Prevent further use until the unit has been completely repaired.

The motor may still be very hot after the overload protection has been triggered or the fan has been switched off → Risk of burning due to hot motor. Note the cooling time. This can be up to 15 minutes, depending on the fan type. Usually, the fan switches back on automatically after cooling down.

Switch off the fan’s power supply before carrying out any work on it → Risk of injury due to unexpected or automatic start-up. The fan may start up automatically after shutting down in response to an overload, clearing of an impeller blockage or accidental switch-on.

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

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.
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.
A mains isolation device with contact openings of at least 3 mm at each pole is mandatory. Only connect unit to a permanent electrical installation with NYM-O or NYM-J type cables, 3x 1.5 mm² or 5x 1.5 mm² (depending on unit type).
The fan may only be operated using the voltage and frequency shown on the rating plate.
Make electrical connections according to circuit diagram.
Check protective conductor continuity on the housing.
The degree of protection stated on the rating plate is only guaranteed if the unit is installed as intended and if the connection cable is correctly guided through the cable grommet(s). The grommets must tightly seal the cable sheathing. The terminal box cover must be properly fitted so that the surrounding seal is tight against the terminal box all the way around.
