Storage
Information
SAB shall not be liable for damage to the duplex filter if it is stored for longer than 6 months from the date of delivery.
The correct storage is the responsibility of the consignee.
It must be ensured for storage that the delivery is placed in a secured and roofed place or covered with a tarpaulin to protect it
from moisture and that spigots, screw connections as well as attachment parts remain unstressed. The duplex filter must not be
stored in a corrosive atmosphere, the relative humidity should be <65%.
If stored for longer than 6 months, the packaging must be checked regularly for damage and replaced if necessary.
4 Installation and assembly
Information
Appropriate protective equipment (see chapter 2 "Safety" → "Personal Protective Equipment") must be worn when
working on and with the duplex filter.
The direction of flow must be observed, never mix up inlet and outlet connections!
Make sure that there are no foreign bodies in the housing (e.g. tools)!
Only work on the housing when it is depressurised!
Installation and assembly may only be carried out by qualified and trained personnel.
The duplex filter is installed upright in the pipeline, using suitable seals and connecting elements. The connected pipelines must
not transfer any mechanical stresses to the filter housing, as the housing connections are not designed for any additional nozzle
loads.
The cast duplex filter consists of two identical single filters. The single filters consist of a cast housing, cover, seals and the basket
or ring strainer insert.
The strainer insert is already installed when delivered.
Appropriate measuring devices must be installed in the inlet and outlet or optionally a differential pressure measuring device to
record the differential pressure.
Attention: These described shut-off devices, piping parts and fittings for differential pressure measurement are not included in
the scope of delivery!
In normal operation, only one filter pot has to be operated, so that the other one is available as a full reserve. This is switched to
during the cleaning phase. This ensures that filter operation is not interrupted. During start-up operation, both filters can be
operated in parallel by setting the stopcock plug (10) to the centre position. This reduces the pressure loss in the filter. This is
particularly advantageous with viscous media that do not heat up until during operation (cold start).
The change-over lever (9) always faces in the direction of the filter pot in operation.
The seals must be clean, undamaged and properly seated. All screw connections must be checked for their leak tightness.

Table 2 Components of the duplex filter
Operating principle and function
The medium flows through the upper connection N1 inlet (14) into the duplex filter.
The medium flows through the strainer insert from the inside to the outside.
The cleaned medium leaves the duplex filter through the lower connection elbow N2 outlet (15).
Start-up
It must be ensured that all connecting and locking elements are correctly installed and firmly tightened before start-up.
Initial condition for the start-up: All valves (inlet, outlet and vent valves) are closed.
1. Bring the Change-over lever into the operating position (in the direction of the filter bowl to be put into operation).
2. Open the vent valve.
3. Open the inlet valve slowly.
Avoid sudden opening as this may damage the filter housing and strainer insert.
4. Close the vent valve as soon as the medium discharges (in the case of dangerous or aggressive liquids, appropriate
measures must be taken to prevent spraying out).
5. Check the entire system for possible leaks under pressure load. Rectify leaks if necessary. In the event of leaks:
a) Shut off the inlet.
b) Carefully relieve the pressure via the bleed or drain screw.
c) Empty the duplex filter.
d) Check the duplex filter for damaged parts.
e) Repeat the start-up procedure.
6. Open the outlet valve slowly to avoid pressure surges.
7. Adjust the desired throughput slowly.
5 Operation
Flow through the duplex filter as evenly as possible. Pressure surges, intermittent pumping and interruption of the flow can result
in damage to the strainer inserts used.
Check the duplex filter at regular intervals. The following should be noted:
1. Vent the duplex filter at regular intervals.
Air pockets in the filter can render part of the filter surface ineffective.
2. Check the duplex filter regularly for leaks.
3. Check the operating pressure and the operating temperature regularly.
4. Check the current differential pressure / degree of soiling of the strainer insert regularly.
If this is within the range of the maximum value specified by the owner for replacement or cleaning, the filter must be taken out of
service and serviced.

Switching Process
In the case of media that have a corrosive effect on the materials of the filter, the changeover must be performed regularly 2-3
times per week.
Ending the operation
The duplex filter filter must be emptied as far as the available pumping possibilities allow (at least to below the strainer support).
1. Close the inlet and outlet.
2. When the drain screw and the vent screw are opened slowly at the same time, the housing is drained and vented.
3. Do not open the housing until it is completely depressurised!
4. After loosening the closing elements, open the filter cover and check the level.
The duplex filter is now ready for maintenance.
To change the strainer inserts, see chapter 4 "Installation and assembly" → "Mounting the strainer insert".
In the case of prolonged downtimes or if the medium hardens, the filter housing must be completely emptied, the strainer inserts
removed and the housing cleaned with a suitable cleaning agent.
Maintenance and care
As soon as one filter half is dirty, the clean filter half is put into operation by slowly switching the stopcock plug.
1. Depressurise the filter pot to be cleaned using the venting and draining equipment.
2. Loosen the cover fasteners using a suitable tool and open the filter.
3. Drain filter using the drain equipment until the level is at least underneath the strainer support
4. Pull the strainer insert upwards out of the housing (use lifting gear if necessary).
5. Clean the strainer insert by blowing out or blasting with compressed air, water or steam.
If necessary, the strainer must be soaked in an appropriate medium and cleaned. Under certain circumstances, optimum
cleaning of the strainer is achieved using ultrasound.
6. For all types of cleaning, it must be ensured that the filter fabric (if present) is not damaged
7. Check the sealing elements for possible damage and replace if necessary.
Seal manufacturers often point out that in the case of pressure-tight connections, the seals must be replaced after the connection
has been opened.
In practice, the seals are often used many times. Resulting leaks are not a sign of system malfunction, but normal wear.

Table 3 Maintenance Schedule
Submissions to the factory / complaints
If the duplex filter is returned to SAB for major repairs or servicing or in the event of a complaint, it must be emptied. In addition, it
must be decontaminated when used with hazardous substances.
The SAB contamination declaration must be completed and enclosed with the delivery; the current version can be requested from
SAB.
6 Service, spare parts and advice
For spare parts, filter accessories and advice, SAB sales personnel and SAB Service are available (see cover page for contact
details).
Availability
SAB always recommends the precautionary procurement and storage of spare parts if the filter system plays a decisive role in
maintaining a production process.
Downtimes can thus be avoided or minimised.
Limitation of the number of load cycles / service life
The permissible number of load cycles service life according to AD- 2000 S1, section 1 .1.4 (unless otherwise agreed). The owner
is advised that the number of load changes that have occurred must be recorded in a suitable way.
