2.2. Functionality of the system
The filter unit serves to suck off and filter polluted air (according to the intended use). The air is purified
on the surface of the filter cartridge in the filter section of the unit. The separated dust is collected in a
dust collecting tank. The activated carbon filter absorbs gases and unpleasant odours. The subsequent
particle filter cleans even fine smokes and dusts. An automatic filter monitoring indicates when a
cleaning or a replacement of the filters is necessary. The purified air is led back into the working room
via an exhaust air grille.
2.3. Intended use
The device is intended for commercial use. If the device is made publicly accessible, it must never be
operated unsupervised by authorized personnel, authorized by the operator.
The intended use of the filter unit is the application combined with laser devices and especially the
extraction and filtration of dusts, fumes and gases.
WARNING
Improper use can damage parts and be a danger to life and limb!
The device must not be used for the extraction of oil-laden welding fume, explosive dust
and gases, hybrid mixtures, glowing or burning substances, gases, water, etc. The
device must not be operated in explosive zones.
Dangers arising from fire.
If the sucked medium is combustible fume or dust, the operator must determine
beforehand which fire protection measures are to be taken.

3. Safety instructions
3.1. Definition of the hazard symbols
The device is constructed according to the state of the art and the recognised safety regulations.
Nevertheless, during use threats to life and limb of the user or other persons may arise. The impairment
of the machine or other property are also possible. In these instructions we warn by using corresponding
indications.
WARNING
WARNING
These instructions are made in case of risks that can lead to injury or death.
CAUTION
CAUTION
These instructions are made in case of risks that can lead to injury.
NOTICE
NOTICE
These instructions are made in case of risks that can lead to material damages.
Information notes are no hazard warnings; they call attention to useful information.
3.2. General safety instructions
WARNING
Dangers arising from improper use / unauthorised operations.
The operator must ensure that their authorised personnel are familiar with all the safety
indications in this manual in advance. The operator is responsible for ensuring that all work
is carried out by authorised and qualified personnel. We therefore recommend using the
training protocol on the last page for that purpose (see chapter “Training protocol”).
Laymen are allowed to operate the device after having received the necessary instructions.
But they are not allowed to carry out any installation, repair or maintenance work.
Dangers arising from fire.
In case of fire, if possible, switch the unit immediately off or disconnect it from the power
supply. Fire extinguishing measures which the operator is obliged to determine beforehand
must be initiated immediately.
The device is additionally equipped with a particle sensor, which can detect an increase of
the particles (eg due to fire, filter break, ...) within the device. The particle sensor thus
provides a monitoring of the particulate matter, but does not provide 100% protection for the
detection of a fire. When the particle sensor is triggered, the device switches off.

WARNING
Dangers arising from electricity.
The operator must ensure that electrical plants and equipment are only built, modified and
maintained by a qualified electrician or under the direction and supervision of a qualified
electrician. Do not work on components if you are not sure that these are disconnected. If
necessary, disconnect the device from the electric power supply and secure it against
unauthorized restarting.
4. Storage, transport and installation of the device
WARNING
Risk of injury from tilting or unmounted components when stored or transported.
The device must be secured against tilting and slipping when it is stored or transported. Do
not stand under or next to the floating load. Lift trucks, forklift trucks and transport cranes
must have a sufficient minimum load bearing capacity. Pay attention to uneven grounds
during the transport. Avoid jerky pushing.
Dangers arising from titling or functional impairments at its destination.
The unit may only be set up on a suitable surface. The surface must be vibration-free and
horizontal. The operator must check the bearing capacity of the surface. As soon as the unit
has reached its intended destination, the brakes of the castors must be activated.
NOTICE
Damage or functional impairment of the unit due to climatic influences.
The unit must be stored in a dry place and protected against moisture during transport. As a
matter of principle, the filter unit is not designed to be installed outside.

5. Commissioning
WARNING
Dangers arising from a defective condition of the unit.
Make sure that the measures described in this chapter are completed before the
commissioning of the unit. All doors of the unit must be closed and all necessary connections
must be attached before turning the unit on. Do not operate the unit if any components are
defective, missing or damaged. Check the orderly condition of the unit before switching it on.
The unit must not be operated without a filter element.
NOTICE
Damaged supply lines.
Make sure that the supply lines are protected against damage by forklift trucks and similar
events. Protect all supply lines from heat, moisture, oil and sharp edges.
5.1. Connecting the suction line and exhaust air line
For extracting the contaminated air, a suction line must be connected to the suction nozzle (see chapter
2.1).
If the air shall be directly sucked off by an upstream machine, the suction line must be connected to the
capture opening of the upstream machine.
The purified air is led back into the working environment via the exhaust air grille (see chapter 2.1)
(recirculation mode). If it is desired to lead the purified air out of the working environment, an exhaust air
pipe must be attached at the discharge grille.
5.2. Electrical connection
CAUTION
Health hazard arising from unintentional cleaning processes.
Switch on the control only if the unit is in operational condition.
NOTICE
Electric malfunction possible in cause of an incorrect power supply.
Pay attention to the admissible supply voltage. Please observe the specifications on the type
plate.
● Connect the mains cable (see chapter 2.1) to the power supply.

5.3. Precoating of the filter cartridges
For a longer service life of the filter cartridges, the new filter cartridges can be pretreated with filter aid
(e.g. precoat). However, this is not necessary when using nano filter cartridges.
Please read and refer to "Precoating new filter cartridges" in the chapter "Maintenance". There
you can also find a description of the operating method of the precoat.
5.4. Connecting the compressed air supply
NOTICE
The compressed air must be dry and oil-free.
According to ISO 8573-1:2010 the compressed air quality must at least meet: [7:4:4]
➔Partikle size: <40µm
➔Pressure dew point: <= +3°C
➔Oil content: <=5mg/m³
5.4.1. Compressed air supply for the cleaning of the filter cartridges
The filter cartridges of the system are automatically cleaned. Cleaning is carried out pneumatically via a
built-in compressed air tank.
Without compressed air supply the filter cartridges will become dirty very quickly.
● The external compressed air supply must be assured with an approved compressed air hose.
For the connection to the device, the compressed air hose must be equipped with a quick
coupling for an insert sleeve DN 7.2.
The compressed air must be dry and oil-free.
● The operating pressure of the compressed air supply must be a minimum of 3 bars and
maximum of 4 bars.
In case of the pressure being too low, the compressed air tank does not reach
quickly enough the operating pressure for the following cleaning. There is a risk of
material damage when the pressure is too high.
● Connect the compressed air hose to the insert sleeve (see chapter 2.1).
