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.

EN | Operating Instructions For your own safety
6 TGE 308-318
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.

EN | Operating Instructions Storing filters and filter elements
TGE 308-318 7
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.

EN | Operating Instructions Filter installation

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.

EN | Operating Instructions Filter installation
TGE 308-318 9
▶The lter must always be tted vertically.
▶Ensure that there is sufcient space below the lter so it can be easily disassem-
bled (see dimension D in the Technical Data).
▶For ATEX-compliant lters:
— Filters for explosive gases as per ATEX must be earthed. For
this purpose, the lters are tted with earthing lugs ex factory (see
also the overview drawings). Establish an appropriate local equi-
potential bonding. Test and document the conductivity.
— 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.

Maintenance tasks
Preparations
Make the following preparations before performing maintenance on lters.
▶When critical gases are fed:
Flush the pipe section in question and the lter with inert gas.
▶Verify the absence of an explosive atmosphere (in line with the
operator’s Directives); if necessary, cancel the EX zone rst. Start
work only then.
▶All gases:
— Block gas supply to the lter.
— Depressurise the lter housing. Make sure the pressure has been positively
relieved.
— Allow lter to cool down
Start work only when these condition are met.
Drain condensate
Draining may be necessary several times a day, depending on the amount of con-
densate produced.
▶Take appropriate measures to prevent the gas from escaping into the atmos-
phere.
▶Drain the collected condensate at regular intervals and properly dispose of it.
Clean filter
ATEX-compliant filters
Dust that has collected on the lter can pose a potential risk. It is
therefore vital to regularly clean the lter. The cleaning interval depends
on the dust concentration in the ambient air. The higher the dust con-
centration, the more frequently must the lter be cleaned.
Beware of static charges!
Never use dry cloths to clean ATEX-compliant filters! A static
charge could build up due to the friction. This could represent an
ignition source.
Therefore: Make sure to clean the filter with a moist cloth only!
▶Clean the lter with a moist cloth at regular intervals to prevent the
formation of hazardous dust agglomerations.
▶Moisten the cloth with water only, wring out thoroughly, do not use
any detergents!
Filters not intended for an ATEX environment
▶Clean the lter with a moist cloth once a week.
▶Moisten the cloth with water only, wring out thoroughly, do not use any deter-
gents!

EN | Operating Instructions Maintenance intervals and work
12 TGE 308-318
Retighten the earthing lugs on ATEX-compliant filters
The earthing lugs on ATEX-compliant lters can loosen over the time.
The conductivity may then be impaired.
▶Tighten the earthing lugs every 6 months.
Replacing filter element and housing O-ring
Replace the lter element every year, but at the latest with a differential pressure of
0.35 bar (0.6–0.8 bar for a high pressure lter). Also replace the housing O-ring.
Beware of damage due to inexpert handling!
Never use unsuitable tools to open and close the filter housings.
Never apply the tool to the thread area. The exerted force could
crush the thread; it would then be impossible to open the filter
again.
Use a suitable open-ended spanner to open and close the filter if
possible. Apply the open-ended spanner to the square at the hous-
ing bottom. Use a similarly suitable tool, e.g. a strap wrench if an
open-ended spanner cannot be used. Apply the tool clearly below
the thread.
TGE filters
▶Make the same preparations as described in section “Preparations” on page 10.
▶Open the lock ring with a hook wrench and take the lower housing out of the
cap.
▶Turn the lter element so that it is in release position, using the click-lock device,
and remove the lter element.
▶Remove the housing O-ring and replace it with a new one.
▶Insert new lter element and lock it in place.
▶Apply a thin coat of grease on the housing threads before assembly if necessary.
Use only TG 1fn thread grease unless any other grease has been agreed upon in
the order!
▶Make sure during assembly that
— the O-rings are properly seated
— the grease does not come into contact with O-rings and sealing surfaces.
▶Insert the lower housing into the cap again and fasten it with the lock ring.
▶For ATEX-compliant lters:
Ensure conductivity, test and document it.
▶Check the housing for tightness.

EN | Operating Instructions Maintenance intervals and work
TGE 308-318 13
Check well running of threads
There is a risk of threads seizing when a lter made of aluminium, steel or stainless
steel is stored.
▶Make the same preparations as described in section “Preparations” on page 10.
▶Open the lter at regular intervals, e.g. every 6 months.
▶Check whether the threads are still sufciently greased and well running.
▶Apply a thin coat of grease on the housing threads before assembly if necessary.
Use only TG 1 thread grease unless any other grease has been agreed upon in
the order!
▶Connect both housing parts again.
▶For ATEX-compliant lters:
Ensure conductivity, test and document it.
▶Check the housing for tightness.
Disposing of filter elements
The lter element or cartridge might be contaminated by the ltered substances.
Heed the notes on hazardous substances for the ltered gas and applicable dis-
posal regulations when disposing.
You can obtain the waste code number for the used materials from the manufac-
turer.

6. Correcting faults
Procedure following a pressure blow
Pressure blows can occur, e.g. when valves are opened suddenly. The lter ele-
ment may still be usable following a pressure blow. But you must rst check it for
damage. A damaged lter element must be replaced.
▶When critical gases are fed:
Flush the pipe section in question and the lter with inert gas.
▶For ATEX-compliant lters:
Ensure conductivity, test and document it.
▶All gases:
— Block gas supply to the lter.
— Depressurise the lter housing. Make sure the pressure has been positively
relieved.
— Allow lter to cool down.
— Remove the element and check it for damage (e.g. cracks or the like).
▶Replace any damaged element (see page 12).
Please contact the manufacturer if pressure blows occur more frequently.
Insufficient filtration capacity
If the ltration capacity is insufcient, although the lter element was replaced at
the correct intervals, then the ambient conditions of use or throughput rates may
not have been matched to the lter used. Contact the manufacturer.
