8. Commissioning
8.1 Before commissioning
›Be sure to read and understand the operating manual before putting the device into operation.
›The information for intended use, the operating conditions and the technical specifications must be adhered to.
›The unit must be positioned so that there is no danger of tipping and vibrations are largely intercepted.
›Cables and hoses must be outside of the movement range of the operating personnel (tripping hazard).
›If no hydraulic oil is sucked in during commissioning, switch off the unit, open the cover at the filter housing and fill in approx.
0.3 l hydraulic oil.
›The oil to be filtered must be compatible with the previously filtered hydraulic oil. If this is not the case, the filter unit must be
cleaned and the filter element is to be replaced (see filter element change).
›When using the hoses during unmanned operation, ensure that they might not fall out of the container.
›The suction and discharge pipe must be immersed far enough below the liquid level, so that oil is sucked in.
›The hydraulic fluid must be free of water (no oil turbidity).
›Properly close the cover of the filter housing.
›Manually turn the cover until it stops; a gap between cover and housing may remain visible (see Figure 3).
Fig. 3: Gap at the filter cover
8.2 After switching on
›With 3-phase AC motors check after connecting if the direction of rotation matches with the direction arrow on the motor.
If not, have it changed by an electrician.
›Check the off-line filter unit for leaks.
8.3 In case of power failure
In order to prevent unintentional starting of the unit, always switch off and unplug the unit.

9. Operation
Exposure to spilled oil
Injury - risk of slipping
›If oil leaks, the oil-covered area must be shut of immediately and covered with an oil binding medium
(risk of slipping).
Static charge
Sparking
›There is a risk of static charge when using poorly conducting hydraulic or lubricating oils.
In this case, please consult the manufacturer.
9.1 Filtering hydraulic fluids in the bypass flow
1. Connect the filter unit to a power source.
2. Place the suction line into the container of the machine or system (e.g. hydraulic tank).
3. Place the pressure line of the pressure limiting valve in the container of the machine or system (e.g. hydraulic tank).
4. Turn on the power supply and plug in the mains plug.
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 off-line 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 power supply and unplug the mains plug.
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.
