Information

Caution: pressure unit! Beforeany work is carried out on thepressure unit, ensure thepressure chamber concerned(filter housing) isdepressurized.

On no account must anyalterations (welding, drilling, oropening by force…) be carriedout on the pressure unit.

It is the responsibility of theoperator to comply with thewater regulations of thecountry concerned.

Statutory accident preventionregulations, safety regulationsand safety data sheets forfluids must be observed.

When working on, or in thevicinity of, hydraulic systems,naked flames, spark generationand smoking are forbidden.

Hydraulic oils and waterpolluting fluids must not beallowed to enter the soil orwatercourses or seweragesystems. Please ensure safeand environmentally friendlydisposal of hydraulic oils andfluids. The relevantregulations in the countryconcerned with regard toground water pollution, usedoil and waste must becomplied with.

Information

Whenever work is carried outon the filter, be prepared forhot oil to escape which cancause injury or scalding due tohigh pressure or hightemperature.

Filter housings must beearthed.

When using electrical cloggingindicators, the electrical powersupply to the system must beswitched off before removingthe clogging indicatorconnector.

1.2. INSTALLATION

Before fitting the filter into the system, check that thepermissible operating pressure of the system does notexceed the operating pressure of the filter.

Refer to the type code label on the filter!

1.3. COMMISSIONING

Check that the correct filter element is fitted. Screw oncover plate, or replace cover plate and then tighten the4 cover plate bolts alternately.

Switch on hydraulic system and check filter for leakage.Vent filter at an appropriate point in the system.

1.6. WARNING NOTES

– If a pipe extension is to be fitted to the outlet of the two-piece filter housing, the pipe must be made of syntheticmaterial or thin-wall aluminium.

– Extensions must be protected by fitting a bulkhead orother means of protection so that no forces can betransmitted to the filter housing or the extension.

– The filter can normally only be used for tank-mounting

– The filter must be fitted absolutely vertically, or, afterconsultation with the manufacturer, only within thetolerances specified.

– The filter must not be used as a suction filter.

– Components (e.g. coolers) must not be fitted after thefilter.

– Special models on request.

2. MAINTENANCE2.1. GENERAL

This section describes maintenance work which mustbe carried out periodically. The operational safety andlife expectancy of the filter, and whether it is ready foruse, depend to a large degree on regular and carefulmaintenance.

2.2. MAINTENANCE MEASURES

– Spare parts must fulfil the technical requirementsspecified by the manufacturer. This is alwaysguaranteed for HYDAC original spare parts

– Keep tools, working area and equipment clean.

– After disassembling the filter, clean all parts, check fordamage or wear and replace parts if necessary.

– When changing a filter element a high level ofcleanliness must be observed!

2.3. INTERVAL BETWEEN CHANGING ELEMENTS

We recommend fitting the filter with a clogging indicator(visual and/or electric or electronic) to monitor the filterelement.

If the clogging indicator responds, it is necessary tochange or to clean the filter element without delay.

If no clogging indicator is fitted, we recommendchanging the elements after specified intervals, aftermax. 1 year (changing the filter element depends on thedesign of the filter and the conditions). Higher dynamicloads across the element might necessitate shorterintervals between changes. Shorter intervals can alsobe expected during commissioning, repairs, oil changesetc. on the hydraulic system.

The standard clogging indicators only respond whenfluid is flowing through the filter. With electricalindicators the signal can also be converted into acontinuous display on the control panel. In this case thecontinuous display must be switched off during a coldstart or after changing the element.

If the clogging indicator responds during a cold startonly, it is possible that the element does not need to bechanged yet.

3. CHANGING THE ELEMENT3.1. REMOVING THE ELEMENT

1. Switch off hydraulic system and release filter pressure

(if necessary, release tank pressure).

2. Size 75 to 270:Unscrew cover plateSize 330 and above:Unscrew cover plate bolts, lift off cover plate.

3. Remove filter element with contamination retainer (ifpresent) by the handle.Check surface of element for contamination residue andlarger particles; these can indicate damage tocomponents.

4. Remove contamination retainer (if present) by turninganti-clockwise (bayonet fitting)Size 210/270:Contamination retainer cannot be removed (fixed).

5. Replace or clean filter element (only W, W/HC and Velements can be cleaned).

6. Clean filter housing and cover plate if necessary.

7. Examine filter, especially sealing surfaces, formechanical damage.

8. Check O-rings and replace parts if necessary.

3.2. FITTING THE ELEMENT

1. Moisten sealing surfaces on the filter housing and coverplate, as well as the O-rings, with clean operating fluid.

2. When fitting a new element, check that the designationcorresponds to that of the old element.

3. Fix contamination retainer (if present) onto the new orcleaned filter element by turning clockwise.

4. Place filter element carefully on to the element spigot inthe bowl.

5. Size 75 to 270:Screw on cover plate by handSize 330 and above:Replace cover plate, screw on cover plate bolts byhand; tighten alternately

6. Switch on hydraulic system and vent filter at a suitablepoint in the system and check filter for leakage.

Note:Contamination or incomplete pressure release on disassemblycan lead to seizing.

Filter elements which cannot be cleaned must be disposed ofin accordance with environmental regulations
