10.4 Monitoring the oil cleanliness when filling machines and systems
1. Connect the filter unit to a power source.
2. Insert the suction lance / suction pipe into the tank of the machine or system (e.g. hydraulic tank).
3. Place the discharge pipe into the machine or system container (e.g. hydraulic tank).

NOTE
›
At the beginning of the filtration, filling of the filter unit may take several seconds.
4. Move the lever to the "Filtering" position.

6. Switch on the filter unit at the on/off switch (circuit breaker) and let it operate for approx. 5 min. (Initialization
of the particle counter and ventilation of the system).
7. Monitor the operation.
8. After the machine or system has been completely emptied, switch off the filter unit at the circuit breaker.
9. Fix the suction lance / suction pipe and the discharge pipe to the corresponding brackets at the filter unit
NOTE
›
No particle counting is possible with the "pumping" lever position.
›
Make absolutely sure that the unit is completely vented. Air bubbles can falsify the measurement results!
›
Make absolutely sure that the specified media temperatures of max. 80 ° C are observed.
›
Incorrect viscosities can falsify the measurement results!
›
An exact determination of the cleanliness class is possible in a viscosity range of 15 mm
