1. PRELIMINARY REMARKS
1.1 Instructions for Use of Filter
This pressure vessel must only be commissioned in conjunction with a machine or
system.
Under the provisions the pressure vessel must only be used according to the operating
instructions of the machine or system.
This pressure unit has to be used with hydraulic- or lubrication fluid only.
The user must ensure appropriate actions to avoid air formation (e.g. venting)
Repairs, maintenance and commissioning must only be carried out by specialist staff. Do
not touch the pressure vessel until cool. Carry out the directions in the operating
instructions of the machine or system.
Attention pressure vessel: please ensure for all works at the pressure vessel that the
referring side of the pressure vessel (filter housing) is released of pressure.
No modifications may be made to the pressure vessel (welding, drilling, forced
opening..).
The operator/owner is to ensure adherence to the National Water Resources Act as well
as local water resources laws and other related regulations.
Adherence is to be maintained to statutory accident prevention regulations, safety
regulations and safety data sheets for fluids.
When working directly on or in the vicinity of hydraulic systems, there is to be no
smoking or open flames/fire, with every effort being taken to prevent the generation of
sparks.
Hydraulic media and water-polluting fluids must not be allowed to soak into the soil, seep
into bodies of water or the sewage system. Ensure that hydraulic media and fluids are
disposed of in an environmentally safe manner. Adherence is to be maintained to
pertinent national and local regulations pertaining to groundwater protection, disposal of
waste/spent oil and (hazardous) waste.
Work on filters may involve leaking hot oil which may cause injury and scalding as result
of its high pressure and/or temperature.
Filter housings must be grounded.

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).

3. MAINTENANCE INSTRUCTIONS
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.

3. Changing the Filter Element
3.1 Removing the Filter Element
1. Open the ball valve (3.1) of the pressure compensation line (3) in order to
enable pressure equalization between the filter housings. Turn the
change-over lever (2) by 90degrees the filter is now changed over to
the other side. Close the ball valve (3.1) of the pressure compensation line (3) again.
2. Loosen the air vent screw (A) on the filter side currently not in operation in order to release
the pressure. Open the oil drain port (B) on the filter side currently not in operation and
drain the contaminated oil into a suitable receptacle. (The oil shall not be used for re-filling
unless having been properly filtered/purified first).
3. Open the cover plate screws and lift up the cover.
4. Pull out the filter element (1) by the stirrup (examine the surface of the filter element for
contamination residue and large-sized particles. This may be an indication of damage at
components).
5. Remove filter element.
6. Clean the housing and the cover plate, if necessary.
7. Check the filter for mechanical damage/wear, paying special attention to the sealing
surfaces.
8. Check the O-Rings and if necessary, change them.
3.2 Installing the Filter Element
1. Wet the sealing surfaces on the filter housing and the cover plate including the seals with
clean hydraulic medium.
2. When installing a new filter element check whether the designation of the new filter
element corresponds to that of the old one.
3. Wet the o-rings of the new elements with clean hydraulic fluid.
4. Carefully mount the filter element (1) on the element spigot in the housing (check the
position of the stirrup on the element).
5. Set the cover plate on top and screw in the cover screws by hand; tighten them by
tightening the screws in opposite corners.
6. Close the oil drain port (B).
7. Open the ball valve (3.1) of the filling line (3) and fill the filter side until oil exits the air vent
screw (A).
8. Close the air vent screw (A).
9. Close the ball valve (3.1) of the filling line (3) and check the filter for leakage.
Note:
Filter elements which cannot be cleaned are to be disposed of in an environmentally safe manner
in accordance wirh environmental protection
regulations.
