Safety instructions regarding installation, operation, cleaning and maintenance

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

Health risk due to deposits on the unit (mould, bacteria, dust etc.). Clean unit at regular intervals, especially after the fan has not been used for a long time.

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 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. Use appropriate climbing aids (ladders). Stability should be ensured, if necessary have the ladders steadied by a 2nd person. Ensure that you are standing securely and cannot lose your balance and that there is no one under the unit.

Danger of electric shock when operating a unit which is damaged or not fully mounted. Switch off all supply circuits. Only operate the unit when it is completely installed. Do not commission a damaged unit.

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 and with cables (0.75 mm² to 1.5 mm²) of type NYM-O or NYM-J.

The unit may only be operated using the voltage and frequency shown on the rating plate.

Unit may be energized even when at a standstill and may be started up automatically by sensors, such as those for time delay or humidity etc.

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 cable grommet. The grommet must tightly seal the cable sheathing.

With protection class I, connect the PE conductor and check the connection.

Danger of burning due to hot bimetal. The integrated bimetal can be very hot after operation of the shutter. Wait until the bimetal has cooled down.

when handling packaging materials. Observe applicable safety and accident prevention regulations. Store packaging material out of the reach of children (risk of suffocation due to swallowing).
