1.2
Installation
Before installing the filter in the hydraulic system check to see whether the
permissible operating pressure of the system corresponds to the value
indicated on the rating plate.
It is to be made certain, that the filter is tastened without tension and no
piping torces will transfer to the filter. With the attachment, system forces at
the filter must be excluded. Tasten ehe filter with stand elevice to the background only it a
compendator, an extension loop, a dampins element or similar were built into the piping.
1.3
Commissioning
Make sure that the designated filter elements (1) have been installed.
Set the cover plate on top and tighten the cover plate screws using the proper torque.
Open the ball valve (3.1) of the pressure compensation line (3), move the control lever (2)
to the middle position and fill the filter unit via the system (both sides of the filter are to be
filled).Vent the filter by loosening the air bleeding screws (A) on the cover plates. Then
move the control lever (2) to either of the filter sides and reclose the ball valve (3.1) of the
pressure compensation line (3).

2.1 General
This section contains a description of the periodical maintenance work to be performed.
The operability, operational reliability and serviceable life of the filter essentially depend on
regular careful maintenance.
2.2 Maintenance Measures
Spare parts are to conform to the technical requirements specified by the manufacturer.
This is always ensured when using original HYDAC spare parts.
Keep tools, working area and equipment clean.
After dismantling the filter clean all components, check for damage or wear, and
replace, if necessary.
When replacing a filter element make sure that everything is kept as clean and dirt-free
as possible in order to prevent the filter from being contaminated.
2.3 Filter Element Changing Frequency
We recommend that the filter elements are changed at pre-defined intervals, however at
least once a year.
If no clogging indicator is fitted, we recommend that the filter elements are changed at pre-
defined intervals, however at least once a year (the element change frequency depends on
the filter design and the conditions to which the filter is subjected). When the filter element
is subjected to high dynamic loading it may prove necessary to change the element more
frequently. The same applies to commissioning, repair work, oil changes etc. in the
hydraulic system.
