6.1 USER INSTRUCTIONS FOR FILTERS
Notice
This pressure equipment
must only be put into
operation in conjunction
with a machine or system.
Notice
The pressure equipment
must only be used as
stipulated in the operating
instructions of the machine
or system.
Notice
This pressure equipment
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.
Caution
Repair, maintenance work
and commissioning must
be carried out by specialist
personnel only.
Allow the pressure equipment to
cool before handling.
The stipulations of the operating
instructions of the machine or
system must be followed.
Danger
Caution: pressure
equipment! Before any
work is carried out on the
pressure equipment,
ensure the pressure chamber
concerned (filter housing) is
depressurised.
Danger
On no account must any
modifications (welding,
drilling, opening by force
etc.) be carried out on the
pressure equipment.
Notice
It is the responsibility of
the owner to comply with
the water regulations of the
country concerned.
Caution
Statutory accident
prevention regulations,
safety regulations and
safety data sheets for fluids
must be observed.
Caution
Filter housing must be
earthed.
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 sewer
systems. Please ensure safe and
environmentally friendly disposal of
hydraulic oils. The relevant
regulations in the country
concerned with regard to ground
water pollution, used oil and waste
must be complied with.
Caution
Whenever work is carried
out on the filter, be
prepared for hot oil to
escape which can cause
injury or scalding as a result of its
high pressure or temperature.
Danger
When using electrical
clogging indicators, the
electrical power supply to
the system must be
switched off before removing the
clogging indicator connector.
Customer Information in respect of
Machinery Directive 2006/42/EC
Hydraulic filters are fluid power parts/
components and are therefore excluded
from the scope of the Machinery
Directive. They do not bear the CE mark.
Before using these components, ensure
compliance with the specifications
provided by HYDAC Filtertechnik GmbH
in this documentation.
The specifications also contain
information on the relevant essential
health and safety requirements (based
on Machinery Directive 2006/42/EC) that
are to be applied by the user.
We hereby declare that the filters
are intended to be incorporated into
machinery within the terms of the
Machinery Directive 2006/42/EC.
It is prohibited to put the filters into
service until the machinery as a whole is
in conformity with the provisions of the
Machinery Directive. Furthermore, our
Terms of Sale and Delivery are available
on our website (www.hydac.com).

6.2 MAINTENANCE, 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 extent on regular and careful
maintenance.
6.3 MAINTENANCE MEASURES
z
Spare parts must fulfil the technical
requirements specified by the
manufacturer.
This is always guaranteed for original
HYDAC spare parts.
z
Keep tools, working area and
equipment clean.
z
After disassembling the filter, clean all
parts, check for damage or wear and
replace parts if necessary.
z
When changing a filter element, a high
level of cleanliness must be observed!
6.4 INTERVAL BETWEEN ELEMENT
CHANGES
In principle we recommend that the
filter element is changed after 1 year
of operation at the latest.
We recommend installing the filter
with a clogging indicator (visual and/or
electrical or electronic) to monitor the
filter element.
If the clogging indicator responds, it is
necessary to change or clean the filter
element without delay (only W and V
elements can be cleaned).
When no clogging indicator has been
fitted, we recommend changing the
elements at specific intervals. (The
frequency of changing the filter elements
depends on the filter design and the
conditions under which the filter is
operated.) When filter elements are
subject to high dynamic loading it may
prove necessary to change them more
frequently. The same applies when the
hydraulic system is commissioned or
repaired or when the oil is changed.
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 yet need to
be changed.
NOTE
The information in this brochure
relates to the operating conditions and
applications described.
For applications or operating conditions
not described, please contact the
relevant technical department.
Subject to technical modifications.
