Filtering liquids in the bypass flow
1. Connect the filter unit to a power source.
2. Place the suction strainer into the container of the machine or system (e.g. hydraulic tank).
3. Place the discharge pipe in a container of the machine or system (e.g. hydraulic tank).
4. Turn the filter unit on at the on/off switch (circuit breaker).
5. Check the oil flow on possibly insufficient immersion depth of the suction pipe in the oil tank.
NOTE
Faulty insertion of the discharge pipe
At the beginning of the filtration, filling of the filter unit may take a few seconds.
6. Using the clogging indicator, check the element for clogging at operating temperature of the medium used.
7. At the end of filtration, pull the suction strainer out of the container of the machine or unit (e.g. hydraulic tank) and draw in
air for max. 30 seconds.
Thus, residual oil from the filter housing and the lines above oil level will be returned via the discharge pipe into the tank of
the machine or unit.
8. Turn off the filter unit by using the circuit breaker.
9. Re-attach the suction strainer and the discharge pipe to the appropriate brackets at the filter unit.
NOTE
Reaching the maximum cleaning performance
In order to prevent a short circuit of the oil flow, the distance between the suction and pressure connection should be
kept as large as possible.
