2. For your own safety
Note:
When carrying out any work on the filters comply with all applicable
national accident prevention regulations!
Intended use
A lter of the series described here must be exclusively used for ltering the gas
noted on the lter’s type label. The technical data specied on the type plate must
be observed and complied with. Any operation at conditions other than those
indicated on the type label is regarded as not intended. Please contact the manu-
facturer if you plan to use the lter for gases other than those indicated on the type
label.
ATEX-compliant lters as per CE Ex II 2G marking must be operated in
zone 1 and zone 2 only.
ATEX-compliant lters are conductive. The operator must make sure con-
ductivity is maintained under all circumstances. He must also make sure
that the conductivity is not impaired by any attachment parts. The con-
ductivity must be tested and approved after each service assignment.
To ensure proper preliminary ltration, a strainer lter must be installed
upstream of any C, CF lter element. Operation of C, CF lter elements is
regarded as not intended if these conditions are not met.
Obvious improper use
Danger when explosive gases are ltered!
Filters not marked with an ATEX code on the type label must not be used
to lter explosive gases or for operation in an explosive environment.
Hazard caused by hot surfaces!
The media that flow through the filter can have a temperature of up
to 80 °C. Do not touch hot surfaces. Note the operating instructions
issued by the operator.
Impermissible maloperation
◊ ltering instable gases (e.g. acetylene).
◊ ltering liquids
◊ conveying solid, dustlike goods.

Hazard areas on the filter
Symbol Hazard area
Warning against overpressure
The entire lter is pressurised during operation. Relieve all pressure before
starting any work on the lter.
Warning against explosive atmosphere/explosive gas
Only lters with the appropriate ATEX code must be used in a potentially
explosive environment and for ltering explosive gases. The lters must be
connected to the customer’s equipotential bonding system (local equipo-
tential bonding).
Beware of critical gases
The ltered gas could be hazardous. Keep appropriate notes on hazardous
substances at hand and heed them when working with critical gases.
Beware of hot surfaces
The ltered gas can be very hot and thus heat up the lter’s surfaces. Do
not touch hot surfaces. Wait until the surfaces have cooled down before
starting work on the lter
Safety notes on specific operating phases
Notes on critical gases
All explosive, ammable and poisonous gases of uid groups 1+2 as per pressure
equipment directive 2014/68/EU are referred to as critical gases.
◊ The release of a critical gas can pose a considerable risk to man and environ-
ment and must therefore be prevented by all means:
— The operator must implement appropriate safety precautions.
— Flush the respective pipe section and the lter with an inert gas prior to all
work that could result in critical gas being released. Then depressurise the lter
and carry out the work.
— .. Verify the absence of an explosive atmosphere (in line with the oper-
ator’s Directives); if necessary, cancel the EX zone rst. Start work only
after applying these measures.
◊ Make sure to heed the notes on hazardous substances for the used gas when
ltering a critical gas!
Notes on transportation and installation
◊ The transportation — in particular of larger build type lters — may be carried
out by specialist personnel only.
◊ Filters damaged during transportation must not be installed.
◊ Store lters, lter elements and cartridges in the unopened original packing in a
clean, dry place until they are used.

Notes on filter operation
◊ Do not perform any unapproved conversions and modications on the lters.
Non-approved modications will endanger the operational safety and may cause
damage or personal injury.
For ATEX-compliant lters:
— Filters for explosive gases as per ATEX must be earthed. Establish an
appropriate local equipotential bonding. Test and document the conduc-
tivity.
— For installation under explosion group IIC:
Make sure when attaching decals or other markings that the area they
cover does not exceed a total contiguous area of 20 cm2!
— Make sure when painting that the permissible coat thickness does not
exceed the limits stipulated for the area of application.
— The control of electronic accessories for ATEX-compliant lters must
be intrinsically safe.
◊ Avoid sudden pressure uctuations on pressure build-up and de-pressurization.
If the pressure builds up or drops, too quickly, this may cause damage to the
lter.
◊ When using accessories with an external power supply, there is a hazard from
electrical voltage. Heed the notes given in the operating instructions for the ac-
cessories. Work on electrical components only when they are deenergised.
Notes on maintenance
◊ Always maintain the prescribed service intervals. If these are not complied with,
the lter may not function correctly and the manufacturer does not accept any
liability whatever for any possible consequences.
◊ Repairs and maintenance should be carried out by specialist personnel only.
Use only suitable tools when working in an explosive environment.
Notes on disassembly and disposal
◊ Flush the entire system, including the lter, with inert gas before disassembling
lters used for ltering critical gases. Depressurise and disassemble the lter
only then.
◊ The lter housing and elements might be contaminated by substances held back
in the lter. Filters used for the ltering of critical gases might contain explosive,
ammable or poisonous substances. Therefore always read the material safety
data sheet of the respective gas. Dispose of all components of the lter accord-
ing to the applicable statutory regulations.

3. Storing filters and filter elements
The storage space must meet the following conditions when the lter is to be
stored for a longer period:
◊ The lter must not be stored out of doors.
◊ The storage space must be dry.
◊ The storage space must be free of dust, or the lter must be packed dustproof.
◊ The storage space must feature an ambient temperature of at least +1 °C.
Caution:
When you want to store the filter for a longer period (e.g. several
months), you must check the threads for well running from time to time
to prevent corrosion
Storing filter elements and cartridges
▶Store lters and cartridges in the unopened original packing until they are used.

4. Filter installation
The lters are supplied in a ready to operate condition and can be installed directly
into the pipe system. To prevent transport damage, any ordered options come
separately packed. These accessories must be tted to the lter before commis-
sioning and in accordance with the respective instructions supplied.
Also heed the information provided in the ancillary documents coming
with the accessories when installing ATEX-compliant accessories!
The control of electronic accessories for ATEX-compliant lters must be
intrinsically safe.
Requirements and preparatory activities
◊ As a rule, the lters should always be used in the pipe system at the point with
the lowest temperature.
◊ Ensure that the pipeline system is free of any contamination and clean it before
installing the lter, if necessary.
◊ To ensure larger particles are safely trapped, a suitable strainer lter must be
installed upstream of any C, CF lter element.
◊ A safety device for maintaining the maximum working pressure and the permis-
sible gas temperature must be available. This safety device must prevent that
limit values are exceeded.
◊ A suitable pressure relief device and a condensate drain must be installed for
the lter. This safety device must prevent critical gas from escaping into the
atmosphere.
Danger due to release of a critical gas!
The release of a critical (explosive, flammable, poisonous) gas
from the network can constitute a considerable risk for man and
environment.
Therefore heed the following before working on filters for critical
gases
— flush the pipe section in question with inert gas
— have the notes on hazardous substances for the used gas ready
— take appropriate protection measures
— verify the absence of an explosive atmosphere
Installation
▶Before installing the lter:
— ush the pipe section in question with inert gas if necessary
— and depressurise the system.
▶Check lter for possible transport damage. Do not t a damaged lter.
▶If necessary, t a bracket or pipe support. Construct the support device such
that it can bear the weight of a lter completely lled with liquid.
▶Heed the ow direction when installing the lter in the pipeline! The gas must
ow through the lter in the direction of the arrow on the upper housing only.
