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.

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

Electric components are a potential source of electric shock.

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.
Only operate the unit when it is completely installed.

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

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.
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 permanently wired electrical installation and with NYM-O or NYM-J cables, depending on the unit variant, 3 x 1.5 mm² or 5 x 1.5 mm².
Units 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 switch on automatically due to sensors (time delay, humidity etc.). Maintenance and fault finding only permissible when carried out by qualified electricians.
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 due to fire transmission

if an incorrect connection duct is connected to the ER housing. Always use the correct duct material for the respective ER housing.
if incorrect ceiling compound is used for exhaust air systems with an intermediate ceiling (PAM-GLOBAL RML or ceiling barrier system). Ensure that the gap remaining between the main duct and wall or ceiling is fully sealed with non-flammable materials resistant to deformation, such as concrete, cement mortar or plaster.
if the seal with the brickwork or wall boards is incorrect. If used outside the shaft, ensure that the gap remaining between the connection duct and brickwork/wall boards is fully sealed with non-flammable materials resistant to deformation, such as concrete, cement mortar or plaster and for the wall boards, special fire protection filler.
if the metal exhaust socket is incorrectly connected to the connection duct. 3 steel blind rivets are prescribed for the connection with the exhaust socket. These must not impair the shutter function. Before commissioning, ensure that the shut-off shutter moves with ease.
if the metal shut-off shutter is not correctly inserted and screwed down in the exhaust socket. During installation, it is essential that the shut-off shutter is correctly positioned and screwed down. The soldered strut must be correctly inserted and the shutter must move with ease.

Risk of injury in case of damaged unit.

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

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.

Never operate the unit without air filters.
Only use original filters.
Regularly change air filter when a filter change is indicated (LED or TimeStrip).
If the unit has not been used for a long time, always replace the air filters.

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.

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.

Risk to health if unit is not correctly cleaned.

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

Exercise caution when handling packaging materials.

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

Non-intended operation/impermissible operation due to incorrectly mounted unit.

Only install unit in accordance with the planning documents.
In particular, note the information on ventilation channels and sound deadening.
Observe planning instructions regarding unit position and distance to other façade components.
If necessary, use isolating elements.
