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.
›
Fasten the unit sufficiently safely and vibration-free only using rubber buffers (Order no. UM 045.0709) (MA 30 +5 Nm).
›
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.
0,5 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.
›
Recommended nominal sizes of the hydraulic connections:
»
Suction hose / suction pipe DN 32
»
Pressure hose / pressure pipe DN 25
›
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).

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.
Danger by improper handling
Material damage
›
The off-line filter unit should be equipped with a suction strainer on the suction side.
A missing or defective suction strainer (Order No. see below) can lead to pump damage.
In this case the manufacturer assumes no liability.
›
With assembly of the off-line filter units, a clogging indicator has to be used.
Without clogging indicator, clogging of the element cannot be observed.
