7 USE OF THE SELF-CLEANING FILTER
The self-cleaning filter is intended exclusively for the filtration of the achieved juice after the pressing.
7.1 JUICE FILTRATION
The filtration process begins when the achieved juice is introduced into the self-cleaning filter through
the pump inlet.
- First connect the tube coming from the sink where the juice is collected to the pump inlet.
- Connect another tube to the outlet of the filter and put it in its final destination (usually a juice tank).
- Once the self-cleaning filter is enabled (see section 6.1 for a description of the procedure), select the desired
function mode (manual or automatic).
- Open the green venting valve located at the top of the vacuum gauge (see section 7.1.1 for more
information) to release any pressure or vacuum built up in the gauge.
It is forbidden to use the machine for any other purpose.
Before starting the filtration process make sure the tubes are properly fitted and all the valves are
open for a correct flow.
Manual mode
- In manual mode the pump and self-cleaning system can be used separately.
- The manual mode can be selected by turning the mode switch to the left; to the position marked with a
»!«.
- In this mode, the user can use the pump only when desired and the time required without turning the self-
cleaning system on. Keep in mind that if the use of the self-cleaning system is required, it has to be turned on
separately by turning the filter switch to »1«position.
- To disable the manual mode, simply turn the mode switch to the »0«
position and the pump will stop. In the
same way, to disable the self-cleaning system the filter switch has to be turned to »0«
position, otherwise it
will continue working non-stop.
Automatic mode
- The automatic mode can be selected by turning the mode switch to the right; to the position marked with a
»!«.
- This mode automatically activates the pump and the self-cleaning system at the same time (without turning
them on separately).
- Usually this mode is used when the self-cleaning filter is connected to a container/sink with a level switch,
which toggles its operation automatically once the container has been filled or emptied.
- To disable the automatic mode, simply turn the mode switch to »0« position (both the pump and the self-
cleaning system will stop).

USER MANUAL – Self-cleaning filter – JF1500/JF3000
NIKO - Fruit processing machinery www.niko-si.si
16
- Once selected the operation mode, the juice will enter to the pump coming from the container/sink and will
pass through the filter; using the inlet valve the juice flow can be regulated.
- After adjusting the juice flow, if the pressure increases during the filtration process, it will be necessary to fully
open the manual valve for sludge outlet for a few seconds, which helps to dispose solid waste and reduce
the pressure (put a bucket under the filter to avoid soiling the work area).
- The juice will come out through the outlet with looking glass, where the filtered juice can be observed.
- Once the juice has reached its final destination, the filtration process is done.
7.1.1 OPENING THE VENTING VALVE
Temperature fluctuations during the process cause the liquid within the gauge to expand and contract, which in
turn increases or decreases case pressure. Move the green valve to open position, which will release any
pressure or vacuum built up in the case. It can be left in open position when working.
If the inlet valve is fully opened, the juice flow will be faster but the pressure will increase.
It is highly recommended to fully open the manual valve for sludge outlet a few seconds every 15
minutes to reduce de pressure inside the filter.
