The hydraulic lters are components intended for use in potentially explosive atmospheres to remove the contaminants
from the hydraulic uids used in the hydraulic systems, maximum pressure up to420bar, ow rate up to150l/min.
2. General warnings
- Before the installation, use or maintenance of the lter carefully read the manual
- The system and the lter are pressurised! Be sure the system is at ambient pressure before starting any activity
- The uid temperature inside the system and the lter can cause injuries to personnel or create a hazardous
environment
- Any activity must be carried out by trained and certied specialists, they must use the correct protective equipment
- Any activity must be carried out using the correct tool
- Any activity must be carried out in accordance with the laws in force in the country where the system is in
operation
- The data shown onto the nameplate must be complete and legible during the whole lter working life

6. Installation
- Check that the system working pressure does not exceed the maximum working pressure of the lter.
The maximum working pressure of the lter is shown on the identication plate
- Check that the lter is compatible with the uid used in the system
- Remove the plastic plugs from the inlet, the outlet and the indicator connection
- Check that the correct lter elements are tted into the lter
- Check the ow direction (the ow is indicated bytwo arrows on the head)
- Install the clogging indicator, if required.
In the case of using an electrical clogging indicator, follow the electrical diagram for correct installation
- Fasten the lter to the bracket with the correct bolts. Be sure to t the lter without any tension stress
- Check that there is appropriate clearance for maintenance and the lter elements replacement.
Correct operation is only guaranteed if the lter is installed in a vertical orientation with the lter housing at the top
- Check for a good view of the clogging indicator
- Connect the lter to the hydraulic system, using the appropriate hydraulic ttings.
7. Commissioning
- Switch on the hydraulic system
- Check the lter is free of leaks
- Check the lter for leaks at the maximum working conditions. (Pressure, temperature …)
- Check the lter does not cause excessive pressure drop checking that the indicator does not show the alarm signal.

8. Standard maintenance
8.1 FILTER ELEMENT REPLACEMENT
The clogging indicator monitors the conditions of the lter element.The alarm signal shown by the differential indicator
during the normal working conditions (Pressure, temperatures …) means that the lter element needs to be replaced.
- Check the right spare lter element is available, compare the spare lter element part number with the part number
shown on the lter name plate or in the spare parts list
- Switch off the system
- For the disassembly and the assembly of the parts, please refer to the tools table in paragraph 3
- (Fig. 1) If provided, unscrew the drain plug after placing a vessel to collect the operating uid
- (Fig. 2) Drain the operating uid from the bottom of the bowl into the collection vessel
- (Fig. 3) Screw the drain plug in referring to the tightening torque table in paragraph 3
- (Fig. 4) If no drain plug is provided, unscrew the lter bowl after placing a vessel to collect the operating uid
- (Fig. 5) Empty the operating uid from the bowl into the collection vessel
- (Fig. 6) Pull the lter element out. Clean the cavity in the housing, the tap and the bowl. Check them for damage
- Check the condition of the bowl seals and, if necessary, replace them referring to the “Special maintenance”
paragraph
- (Fig. 7) Lubricate with the operating uid the lter element O-ring, the housing tap and cavity, then t the lter
element on the tap. Pay attention not to damage the O-ring seal
- (Fig. 8) Lubricate the thread and the O-ring of the bowl, then screw the bowl in referring to the tightening torque
table in paragraph 3
- Switch on the system and check the lter for leaks at the maximum working conditions (pressure, temperature…)
- Dispose of the replaced parts and the collected uid in accordance with the laws in force in the country of use
of the product.

6. Installation
- Check that the system working pressure does not exceed the maximum working pressure of the lter.
The maximum working pressure of the lter is shown on the identication plate
- Check that the lter is compatible with the uid used in the system
- Remove the plastic plugs from the inlet, the outlet and the indicator connection
- Check that the correct lter elements are tted into the lter
- Check the ow direction (the ow is indicated by an arrow on the head)
- Install the clogging indicator, if required.
In the case of using an electrical clogging indicator, follow the electrical diagram for correct installation
- Fasten the lter to the bracket with the correct bolts. Be sure to t the lter without any tension stress
- Check that there is appropriate clearance for maintenance and the lter elements replacement.
Correct operation is only guaranteed if the lter is installed in a vertical orientation with the lter housing at the top
- Check for a good view of the clogging indicator
- Connect the lter to the hydraulic system, using the appropriate hydraulic ttings.
7. Commissioning
- Switch on the hydraulic system
- Check the lter is free of leaks

8.1 FILTER ELEMENT REPLACEMENT
The clogging indicator monitors the conditions of the lter element.The alarm signal shown by the differential indicator
during the normal working conditions (Pressure, temperatures …) means that the lter element needs to be replaced.
- Check the right spare lter element is available, compare the spare lter element part number with the part number
shown on the lter name plate or in the spare parts list
- Switch off the system
- For the disassembly and the assembly of the parts, please refer to the tools table in paragraph 3
- (Fig. 1) Unscrew the lter bowl after placing a vessel to collect the operating uid
- (Fig. 2) Empty the operating uid from the bowl into the collection vessel
- (Fig. 3) Pull the lter element out. Clean the cavity in the housing, the tap and the bowl. Check them for damage
- Check the condition of the bowl seals and, if necessary, replace them referring to the “Special maintenance”
paragraph
- (Fig.4) Lubricate with the operating uid the lter element O-ring,the housing tap and cavity,then t the lter element
on the tap. Pay attention not to damage the O-ring seal
- (Fig.5) Lubricate the thread and the O-ring of the bowl, then screw the bowl in referring to the tightening torque table
in paragraph 3
