13 Important notice for correct disposal of the product
It is essential that the disposal is carried out in compliance with the above and in full compliance with the relevant regulations in force
in the user's country.
Since different regulations to observe are in force in the individual countries, the prescriptions imposed by local laws and by the competent authorities
must be observed. Important! The strainer demolition must be carried out by specialized personnel.
Before starting the disassembly, it is necessary to create around the strainer a sufficiently large and orderly space in order to allow all
the movements without problems of further risks created by the environment.
The machine, in "out of service" conditions, must be positioned in an area accessible only to authorized personnel.
To disable the strainer, it is necessary to:
Switch off and empty the hydraulic system setting it in safe conditions and disconnecting the device from it. Deactivate the electrical system
disconnecting the cables from the line to the electrical panel and from the electrical panel to the machine.
The strainer components disposal must be carried out by specialized recovery centers.
At the end of its working life, the product must not be disposed of as urban waste. It must be taken to a special differentiated waste
collection centres set up by local authorities or to dealers providing this service. Disposing of an electric or electronic appliance
separately avoids possible negative consequences for the environment and health deriving from inappropriate disposal and enables
the constituent materials to be recovered to obtain significant savings in energy and resources. As a reminder of the need to dispose
of electric and electronic appliances separately, the product is marked with a crossed-out wheeled dustbin.
Disposal of batteries: please respect the environment. Do not throw batteries into household waste. Used batteries must be delivered
to the appropriate collection centres. We would like to remind you that only spent batteries can be thrown into the used battery
collection bins. If the battery is not completely down, measures must be taken to prevent a short circuit. The crossed-out wheeled bin
mark indicates the obligation to dispose of batteries separately
All verification and checking operations must be carried out by qualified, trained and equipped personnel.
14 Malfunctions - Troubleshooting
21
Malfunction
Solution
Repeated cleaning cycles
- quality of the liquid to be filtered
- the system capacity must comply with the minimum operating capacity
- the strainer must not work out of maximum capacity
- the working pressure must be at least 1.5 bar
-
D
p set too low
Degree of filtration not consistent
- strainer discs wear status
- rear seal ring wear status
The air vent valve leaks
- Replace the valve. It is recommended to periodically clean the combined
strainer to avoid this malfunction. To disassemble the valve it is necessary
to turn off the system, cut-off the device, disconnect the electric supply and
make the replacement after having removed pressure (and in cold conditions)
Leakage of liquid from the cover closing flange
