5.1.5 Grinder system
The grinder system consists of two parts, a stationary grinder ring
and a rotating grinder head. See fig. 5.
The grinder ring is secured to the pump housing by means of a
bayonet socket and fixed in the right position with a screw.
The grinder head is secured to the shaft by means of the screw
that keeps the impeller in position. To adjust or replace grinder
system, see service instructions.

5.1.6 Level sensor
The piezoresistive pressure sensor placed in the controller is
connected via a hose to a pressure tube in the tank. The screw
cap where the hose is connected includes a condensate trap and
a connection for a DN 100 tube. This tube, the pressure tube,
extends down into the tank. The rising liquid level compresses the
air inside the pressure tube and hose, and the piezoresistive
sensor transforms the changing pressure into an analogue signal.
The control box uses the analogue signal to start and stop the
pump and to indicate high water-level alarm. The pressure tube is
fixed underneath the screw cap and can be taken out for
maintenance, service and for cleaning the inside of the tube.
An O-ring ensures tightness.
The hose is supplied in a length of 10 m. The hose must be
connected to the controller.
