4.2.4 Adjusting the level sensor
NB
Prior to servicing, read section 2.7.
Place the level sensor 50–100 mm below the overflow
wall. Optimal placement depends on the turbulence of
the water surface.
4.2.5 Setting of level relay
NB
Prior to servicing, read section 2.7.
The sensitivity of the level sensor can be set from MIN
to MAX on the level relay’s upper adjusting screw.
The lower adjusting screw must always point to the side marked EMPTY, on this side there are
three different sensitivity ranges, H, S and L. If appropriate sensitivity cannot be set using the
selected sensitivity range, another sensitivity range can be chosen.
4.3 Backwash system
NB
Prior to servicing, read section 2.7.
The system pressure for backwashing must be set to 7-9 bar.
Newly connected pipe systems for external wash water should be flushed before they are
connected to the filter. Thoroughly check that the nozzles are not blocked, see section 6.3.
