1. Description
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. FZH lters are made of stainless steel to meet
extreme conditions and corrosive environments, with maximum pressure up to700 bar, ow rate up to50 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
- Connect the lter with an anti-loosening system and regularly check the condition of the connection
- The declared performances and the safety of the product are only guaranteed when MP Filtri original spare parts
are used
- Warranty is only effective if MP Filtri original spare parts are used.

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 laser marking on the head
- 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 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.
