10.5 Monitoring the oil cleanliness when cleaning machines and systems in the bypass flow
1. Connect the filter unit to a power source.
2. Insert the suction lance / suction pipe into the oil barrel (e.g. fresh oil).
3. Place the discharge pipe into the machine or system container (e.g. hydraulic tank).

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. Check the oil flow for a possible insufficient insertion depth of the suction pipe in the oil tank.
8. Monitor the operation.
9. After completion of the filtration, pull the suction lance / suction tube out of the container of the machine or system (e.g.
hydraulic tank) and suck air for max. 30 seconds. Thus, the residual oil from the filter housing and the lines above the oil level is
fed back into the container of the machine or system via the discharge pipe.
10. Switch off the filter unit at the circuit breaker.
11. Fix the suction lance / suction pipe and the discharge pipe to the corresponding brackets at the filter unit.
