3.2 Explanations of the symbols Safety advice, it’s non observance can lead to severe damages of persons or property damages.

Advice – it’s non observance can lead to damages or malfunctions.

General note 3.3 General safety advices Before installing the high pressure filter station the existing operation conditions must be verified. The suitability of all medium touching parts (single aggregates, gaskets, filter elements etc.) is to be verified as well regarding their chemical stability.

The high pressure filter station may be dangerous if it is not used properly or not according to it’s intention. The high pressure filter station must only be installed and put into operation by persons who are familiar with this operation manual and the valid rules of occupational safety and accident prevention. In particular we herewith underline the law for technical 27.10.05

5 / 11

UI 3195-001 working material (Gerätesicherheitsgesetz), the occupational safety (BetrSichVO), the regulation for pressure drums (DruckbehV), the guideline for pressure devices (PED), the operator guideline RL 99/92/EG (ATEX 137) and the Ordinance on Hazardous Substances (GefStoffV).

Within the frame of his safety rough draft the operator has to check which consequences may result from a failure of the inline filter and if additional safety measures must be taken.

4 Intended use The high pressure filter station serves the filtration of HFA-emulsion, within the range of flow-, pressure-, temperature- and chemical resistance. It is recommended to install the high pressure filter station at the bank entrance. If the high pressure filter station shall be used outside this stipulated range of application, you have to obtain a written release note from SEEBACH GmbH. 5 Delivery The high pressure filter station is packed in a completely mounted condition. Please unpack the high pressure filter station carefully and make sure that no single components are left in the packing material which might then get lost.

6 Description In this operation manual only specialties are described which result from the operation of the high pressure filter station.

A detailed description of the installed automatic-backflush filter type must be taken from the relevant operation manual.

The numeration of the below described single components corresponds to the numeration in chapter 1.1.

The feed (left side) to the high pressure filter station is effected over two stopcocks of the connection size DN 50 SS (2), which are subsequently connected with one automatic backflush filter each of the type 3082-014 (4). After both automatic backflush filter a stopcock (6) each is installed. On the outlet side the partial flow rates of the automatic backflush filters are combined and led to the consumers over connections DN 50 SS. This model allows a continuous operation of the high pressure filter station for the case that there is only one filter string available due to failure or maintenance of one automatic backflush filter.

The flow may be locked for each single automatic backflush filter.

The non-return valves (1) installed in the backflush lines avoid that backflush fluid of the one backflush filter flows into the circuit of the other backflush filter. Therefore it is possible to do maintenance or repair work at one automatic backflush filter while the second one keeps operating.

27.10.05

UI 3195-001 7 Installation The high pressure filter station is installed in the line before the components that are to be protected. When connecting the inlet and outlet lines consider the flow direction arrows (see chapter 1.1).

It must be insured that the max. permissible operating pressure, which is indicated on the nameplate (see chapt. 1.1, pos. 5) of the high pressure filter station, is not exceeded.

The backflush outlet must be installed with a high pressure hose in a way that the backflushed fluid can be led out without back pressure into the system return line without any danger for the operating personell.

No stopcock must be installed in the return line.

The two solenoid valves of the automatic backflush filters have to be connected electrically according to the manufacturer’s documentation.

Close all stopcocks.

8 Initial operation / start-up The high pressure filter station must only be set into operation when it is assured that all connections have been duly effected.

Slowly open the two stopcocks inlet (chap. 1.1, pos. 2) and let the medium which is to be filtrated flow into the automatic backflush filter of the high pressure filter station. Abrupt opening must be avoided in any case as a sudden pressure surcharge may cause damages to the tube system or to the following aggregates.

Now, the high pressure filter station is ready for operation.

Slowly open the stopcocks outlet (chap. 1.1, pos. 6), thus the automatic backflush filters are switched online and are operating.

Check the high pressure filter station for possible leakages.

During the regular operation of the high pressure filter station both automatic backflush filters are operating in parallel.

9 Backflushing The backflush process of the two automatic backflush filters is described precisely in the relevant operation manual.

Upon operation of the high pressure filter station make sure that always only one filter chamber is backflushed. The backflush process can be effected time- and differential pressure-dependent. In any case it should be insured that at least one backflush process for each filter chamber is released per shift.

The backflushing is effected with high pressure. Do not remove the connection DN 20 of the backflush outlet of the high pressure filter station, by no means.

After the double solenoid (one magnet) valve has been controlled, a break of at least 2 seconds until the double solenoid valve is controlled the next time must be kept.

27.10.05

7 / 11

UI 3195-001 The relief of the air drain screw „A“ recommended in chapter no. 6 of operation manual UI 3082-014 is already realized in this high pressure filter station.

10 Maintenance 10.1 In general Never perform maintenance work under pressure.

It must be insured that the double solenoid valve does not receive a starting signal for hydraulic control during the maintenance work.

Maintenance works at electrical components must only be effected by qualified staff.

After a certain operation period (depending on the contamination rate, no. of flushes and pressure fluctuations) the high pressure filter station must undergo a maintenance. If load changes and vibrations occur the high pressure filter station must be checked for damages and solid seat of the screw joints / connections regularly. In case of an external leakage the relevant gasket must be replaced. If the leakage does not vanish verify all sealing areas and replace faulty parts immediately.

The maintenance intervals for the automatic backflush filters of the high pressure filter station result from the relevant operation manual.

If faulty parts are not replaced this may lead to the failure of the system.

Use only original replacement parts.

10.2 Pressure relief Precautions to protect against fluid that might be squirting out must be taken.

- Close the stopcocks / inlet (chapt. 1.1, pos. 2).

- Close the stopcocks / outlet (chapt. 1.1, pos. 6).

- Relieve the outlet lines behind the stopcocks / outlet from pressure.

- Relieve the automatic backflush filters (chapt. 1.1, pos. 4) from pressure according to the instructions in the relevant operation manual (it is not necessary to remove the drain hoses for the hydr. reversing mounted at the two filters – see chapt. 1.1, pos. 3).

- Make sure that the pressure gauges of the automatic backflush filter indicate a pressure value of 0 bar.

Note: The pressure relief of only one filter string is to be effected in the sense of the above described instructions. However, bear in mind that behind the stopcock / outlet of the filter string that has been taken out of operation there is still existing the outlet pressure of the continuously operating filter string!

3 General notes 3.1 Explanation of the symbols Safety advice, its non observance can lead to severe damages to persons or properties.

Advice – its non observance can lead to damages or malfunctions.

General Note.

3.2 General safety advices Before installing the automatic backflushable filter the existing operating conditions must be verified. The suitability of all medium touching parts (filter housing, gaskets, filter elements etc.) is to be verified as well regarding their chemical stability.

The automatic backflush filter may be dangerous if it is not used properly or not according to its intention. The automatic backflush filter must only be installed and put into operation by persons who are familiar with this operation manual and the valid rules of occupational safety and accident prevention. In particular we herewith underline the law for technical working material (Gerätesicherheitsgesetz), the occupational safety (BetrSichVO), the regulation for pressure drums (DruckbehV), the guideline for pressure devices (PED) and the Ordinance on Hazardous Substances (GefStoffV).

Within the frame of his safety concept the operator has to verify which consequences may result from a failure of the automatic backflush filter and if additional safety measures must be taken.

14.09.05

4 / 10

UI 3082-014 4 Intended use The automatic backflush filter serves the filtration of water, HFA, oil (hydraulic-, mineral-, grease-, cutting oil) and flame resistant low viscosity fluids, within the range of flow-, pressure-, temperature- and chemical resistance indicated in the relevant data sheets. If the automatic backflush filter shall be used outside this range, you have to obtain a written release note from SEEBACH GmbH. 5 Delivery The automatic backflush filter is packed in completely mounted condition. Please unpack the automatic backflush filter carefully and make sure that no single parts remain in the packing material which might then get lost.

The stopcocks shown in figure 1 (inlet/outlet) are not part of the scope of supply.

Depending on the execution of the automatic backflush filter (as stipulated in the order) the valves and the connecting plate shown in figure 1 may not be mounted, i. e. these are not part of the scope of supply.

6 Description The automatic backflush filter is suitable for installation in pressure lines. The backflush process can be controlled by a host system, time- or pressure-dependent.

Growing contamination of the filter elements leads to increase of the differential pressure.

The differential pressure is recorded by the pressure sensors (not part of the scope of supply). In case of a diff. pressure of approx. 6-10 bar the control of the two way valves is deferred. The L-balls installed in the hydraulic reversings are turned by 90° and thus swing from filter position into backflush position. The position of the L-balls is visually recognizable by the notch of the ball switch shafts (see figure 2).

By means of the non-return valves in the backflush outlet the minimum pressure, which is required for the switch-over and the backflush process, is maintained.

7 Installation The filter is installed in the line before the components being protected. When connecting the inlet and outlet lines consider the flow direction arrows (pict. 1). Also consider that there must be free access for backflushing and for changing the filter elements.

It must be checked that the maximum permissible operating pressure which is indicated on the nameplate of the filter is not exceeded. The permissible differential pressure of the filter elements must also not be exceeded.

A stopcock must already be installed in the inlet and outlet lines (see figure 1).

The backflush outlets must be installed so that the backflushed fluid can be led into a pressureless system return line without any danger for the operating staff.

No stopcocks must be installed in the back-flush outlets.

14.09.05

5 / 10

UI 3082-014 If the medium being cleaned is coarsely contaminated (particle size > 1 mm) we recommend to install a pre-filter before the automatic filter. The internal protective filters of the hydraulic reversings can block in case of high contamination rate of the medium.

Therefore, in case of extremely contaminated media, it is recommendable to control the reversings externally with cleaned high pressure fluid.

One connection each is available at the valve- and outlet plate for the two pressure sensors (figure 1).

8 Start-up Confirm proper installation of correctly rated components prior to putting the filter into service.

Slowly open the stopcock at the inlet side. Abrupt opening must be avoided in any case, as the filter chambers or the filter elements may be destroyed.

Now the automatic back-flush filter is ready for operation.

Slowly open the stopcock at the outlet side, thus the automatic back-flush filter is switched online and operating.

During operation both filter chambers are working in parallel.

Check the automatic back-flush filter for possible leakages.

9 Back-flushing The lifetime of the filter elements installed depends on the contamination of the fluid being filtered, therefore a binding statement regarding time and frequency of back-flushes cannot be made. A general recommendation would be one back-flushing of the filter elements per shift.

Back-flushing is effected with high pressure.

Back-flushing of the filter chambers is effected by electrical activation of the double solenoid valve.

Only one side each of the double solenoid valve must be activated (backflushing of one filter chamber).

The period of activating the double solenoid valve takes approx. 2 seconds.

After reset is done backflushing of the second filter chamber may be effected by the relevant activation of the double solenoid valve.

Back-flushing effects that almost all dirt particles are flushed out of the filter and led out through the back-flush outlets.

As for the automatic filter the own medium is used for reversing, a certain pressure and volume flow is always necessary. If the back-flush process takes too much time, there is the possibility to remove the air drain screws “A” (figure 1). The internal reversing fluid (approx.

0,06 litres per reversing) may then be led out separately.

High pressure.

14.09.05

6 / 10

UI 3082-014 In case of faulty switch process (back-flush process) the function of the double solenoid valve must be verified mechanically and electrically. If the double solenoid valve is activated from above ground, the correct signal transmission to the double solenoid valve must be verified.

10 Maintenance 10.1 General Never do maintenance work under pressure.

Make sure that the double solenoid valve does not receive any tripping signal for hydraulic activation during maintenance work.

Precautions to protect against possibly squirting out fluid must be taken.

After a certain operating period (depending on contamination rate, no. of backflushes and pressure fluctuations) the filter must undergo maintenance. If load changes and vibrations occur the filter must be checked regularly for damages and solid seat of the screw joints. In case of external leakage change the corresponding gasket. If the leakage does not vanish verify all sealing areas and replace faulty parts immediately.

The filter elements and the switch valves are subject to normal wear and tear during service, so that they should be verified after 1000 backflushes each, however, at least every 6 months. Parts which show wear and tear or damages must be replaced immediately. For replacing the filter elements dismount the outlet plate. After having unfastened the screws the outlet plate with the filter elements may be pulled out.

Also the filters of the hydr. reversings must be replaced.

The O-rings of the filter chambers must be checked for damages and if necessary they must be replaced.

If faulty parts are not replaced this might lead to the failure of the system.

Use only genuine replacement parts.

If, in the course of maintence work, srew joints are unfastened at the automatic back-flush filter, take care of the torques indicated in the service drawing when mounting.

10.2 Pressure relief Never do maintenance work under pressure.

- Close the control lines with the two needles „B“ (figure 1), i. e. turn these two needles clockwise to dead stop.

- Unfasten the air drain screws "A", "C" and "D" of both hydraulic reversings, until medium is visibly getting out.

14.09.05

7 / 10

UI 3082-014 By unfastening the air drain screws the medium under pressure is getting out.

- Take off the discs (2US 3082-010, item 20) from the switch shafts.

- Turn both ball switch shafts into back-flush position.

11 Emergency operation For the emergency operation (e.g. in case of a power failure or blocking of the filters of the hydr. reversings), there is the possibility to interrupt the pressure feeds of the hydr. reversings and to manually activate the ball switch shafts. Thus the filter can be re-switched into back flush position or filter position and switched back.

Close the control lines with the two needles „B“ (figure 1) (both needles clockwise to dead stop). Then unfasten the air drain screws "A", "C" and "D" of both reversings until medium gets out visibly.

Unfastening the air drain screws effects that the medium under pressure gets out.

The safety ring at the needles "B" (2US 3082-010, item 29) must not be unfastened.

Then remove the discs (2US 3082-010, Pos. 20).

Now the ball switch shafts are accessible and may be actuated manually.

3 General Notes 3.1 Explanation of the symbols Safety advice, it’s non observance can lead to severe damages of persons or property damages.

Advice – it’s non observance can lead to damages or malfunctions.

General Note.

3.2 General safety advices Before installing the non-return valve the existing operation conditions must be verified. The suitability of all medium touching parts (filter housing, gaskets, filter elements etc.) is to be verified as well regarding their chemical stability.

The non-return valve may be dangerous if it is not used properly or not according to it’s intention. The non-return valve must only be installed and put into operation by persons who are familiar with this operation manual and the valid rules of occupational safety and accident prevention. In particular we herewith underline the law for technical working material (Gerätesicherheitsgesetz), the operational safety regulations (BetrSichVO), the regulations for pressure drums (DruckbehV), the guideline for pressure devices (PED) and the dangerous substance regulations (GefStofV).

The operator has to check in line with his safety concept which consequences may result from a failure of the non-return valve and if additional safety measures must be taken.

03.03.05

4/7

UI 1456-002 4 Intended use The non-return valve serves the protection of aggregates against flow in reverse flow direction and protection of aggregates against system-dependent retroactive pressure surges. The non-return valve is designed for the flow of water, HFA, oil (hydraulic-, mineral-, grease-, cutting oil) and fire resistant low viscosity fluids within the within the range of flow-, pressure-, temperature- and chemical resistance. If non-return valve shall be used outside this range, you have to obtain a written release note from SEEBACH GmbH. 5 Delivery The non-return valve is delivered in completely mounted condition. Please unpack the nonreturn valve carefully and make sure that no single parts are left in packing material which might then get lost.

6 Description The non-return valve is suitable for installation in pressure lines.

The medium flows against a cone (cone stub) whose perimeter area seals radially with a sealing surface situated at the screw-in sleeve. The cone is pressed against the sealing surface by means of a compression spring inserted on the rear side. If the spring force has been prevailed by the pressure of the flowing in medium the cone rises from the sealing surface and the medium flows through the radially situated drillings to the outlet of the nonreturn valve.

The cone opens as soon as the inlet pressure exceeds 0,8 bar respectively as soon as it is by 0,8 bar higher than the oulet pressure. If, from the outlet, increased pressure (pressure shocks) act on the non-return valve, the cone is pressed against the sealing surface in addition of spring force and pressure force. The non-return valve closes, and so the pressure shock is not transmitted towards the inlet.

For medium that flows in from the rear side, i. e. from the outlet side, the non-return valve is closed. Flow in reverse direction is safely prevented.

The housing of the non-return valve is composed of two parts and screwed together.

7 Installation It must be assured that the maximum permissible operating pressure is not exceeded.

The non-return valve must be installed free of tension. When connecting the non-return valve consider the flow direction arrow (chapter 1, illustration 1).

8 Start-up Confirm proper installation of correctly rated components prior to putting the nonreturn valve into service.

After start-up check the non-return valve for possible leakages.

03.03.05

5/7

UI 1456-002 9 Maintenance The non-return valve is maintenance-free, i. e. a disassembling of the non-return valve during maintenance work is not necessary.

If load changes and vibrations occur the non-return valve must be checked for damages and solid seat of the screw joints regularly. In case of an external leakage the relevant gasket must be replaced. If the leakage does not stop check all sealing surfaces and replace faulty parts immediately.

Never perform maintenance work under pressure.

Use only Seebach replacement parts.

10 Disposal The disposal of the non-return valve is effected according to the rules of the scrap metal disposal respectively to the rules of the country where the non-return valve is installed. If the non-return valve is contaminated with remainders of the factory, additional regulations for the disposal regarding these remainders have to be observed.

Subject to technical modifications without prior notice; (print) faults and errors excepted.
