INSTRUCTIONS
1.1.
SAFETY INSTRUCTIONS
Information
This pressure unit must only
be operated in conjunction
with a machine or a system.
Danger
Caution: pressure unit! Before
any work is carried out on the
pressure unit, ensure the
pressure chamber concerned
(filter housing) is
depressurized.
Caution
Whenever work is carried out
on the filter, be prepared for
hot oil to escape which can
cause injury or scalding due to
high pressure or high
temperature.
Danger
Information
The pressure unit must only be
used in accordance with the
requirements of the operating
instructions of the machine or
system.
On no account must any
alterations (welding, drilling, or
opening by force…) be carried
out on the pressure unit.
Information
Information
This pressure unit must only
be operated using hydraulic or
lubricating fluid.
Caution
The user must take appropriate
action (e.g. venting) to prevent
the formation of air pockets.
It is the responsibility of the
operator to comply with the
water regulations of the
country concerned.
Caution
Filter housings must be
earthed.
Danger
When using electrical clogging
indicators, the electrical power
supply to the system must be
switched off before removing
the clogging indicator
connector.
Caution
Statutory accident prevention
regulations, safety regulations
and safety data sheets for
fluids must be observed.
Caution
Repair, maintenance work and
commissioning must only be
carried out by trained
personnel.
Ensure the pressure unit has
cooled down before handling.
The stipulations of the
operating instructions of the
machine or the system must be
followed.
Caution
When working on, or in the
vicinity of, hydraulic systems,
naked flames, spark generation
and smoking are forbidden.
Caution
Hydraulic oils and water
polluting fluids must not be
allowed to enter the soil or
watercourses or sewerage
systems. Please ensure safe
and environmentally friendly
disposal of hydraulic oils and
fluids. The relevant
regulations in the country
concerned with regard to
ground water pollution, used
oil and waste must be
complied with.

INSTALLATION
Before fitting the filter into the system, check that the
permissible operating pressure of the system does not
exceed the operating pressure of the filter.
Refer to the type code label on the filter!

COMMISSIONING
Check that the correct filter element is fitted. Screw on
cover plate, or replace cover plate and then tighten the
4 cover plate bolts alternately.
Switch on hydraulic system and check filter for leakage.
Vent filter at an appropriate point in the system.

WARNING NOTES
If a pipe extension is to be fitted to the outlet of the twopiece filter housing, the pipe must be made of synthetic
material or thin-wall aluminium.
Extensions must be protected by fitting a bulkhead or
other means of protection so that no forces can be
transmitted 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, after
consultation with the manufacturer, only within the
tolerances specified.
The filter must not be used as a suction filter.
Components (e.g. coolers) must not be fitted after the
filter.
Special models on request.

MAINTENANCE
2.1.
GENERAL
This section describes maintenance work which must
be carried out periodically. The operational safety and
life expectancy of the filter, and whether it is ready for
use, depend to a large degree on regular and careful
maintenance.
2.2.
MAINTENANCE MEASURES
Spare parts must fulfil the technical requirements
specified by the manufacturer. This is always
guaranteed for HYDAC original spare parts
Keep tools, working area and equipment clean.
After disassembling the filter, clean all parts, check for
damage or wear and replace parts if necessary.
When changing a filter element a high level of
cleanliness 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 filter
element.
If the clogging indicator responds, it is necessary to
change or to clean the filter element without delay.
If no clogging indicator is fitted, we recommend
changing the elements after specified intervals, after
max. 1 year (changing the filter element depends on the
design of the filter and the conditions). Higher dynamic
loads across the element might necessitate shorter
intervals between changes. Shorter intervals can also
be expected during commissioning, repairs, oil changes
etc. on the hydraulic system.
The standard clogging indicators only respond when
fluid is flowing through the filter. With electrical
indicators the signal can also be converted into a
continuous display on the control panel. In this case the
continuous display must be switched off during a cold
start or after changing the element.
If the clogging indicator responds during a cold start
only, it is possible that the element does not need to be
changed yet.

CHANGING THE ELEMENT
REMOVING THE ELEMENT
1. Switch off hydraulic system and release filter pressure
(if necessary, release tank pressure).
2. Size 75 to 270:
Unscrew cover plate
Size 330 and above:
Unscrew cover plate bolts, lift off cover plate.
3. Remove filter element with contamination retainer (if
present) by the handle.
Check surface of element for contamination residue and
larger particles; these can indicate damage to
components.
4. Remove contamination retainer (if present) by turning
anti-clockwise (bayonet fitting)
Size 210/270:
Contamination retainer cannot be removed (fixed).
3.2.
FITTING THE ELEMENT
1. Moisten sealing surfaces on the filter housing and cover
plate, as well as the O-rings, with clean operating fluid.
2. When fitting a new element, check that the designation
corresponds to that of the old element.
3. Fix contamination retainer (if present) onto the new or
cleaned filter element by turning clockwise.
4. Place filter element carefully on to the element spigot in
the bowl.
5. Size 75 to 270:
Screw on cover plate by hand
Size 330 and above:
Replace cover plate, screw on cover plate bolts by
hand; tighten alternately
6. Switch on hydraulic system and vent filter at a suitable
point in the system and check filter for leakage.
5. Replace or clean filter element (only W, W/HC and V
elements can be cleaned).
6. Clean filter housing and cover plate if necessary.
7. Examine filter, especially sealing surfaces, for
mechanical damage.
8. Check O-rings and replace parts if necessary.
Note:
Contamination or incomplete pressure release on disassembly
can lead to seizing.
Filter elements which cannot be cleaned must be disposed of
in accordance with environmental regulations
