Before starting the Cavitator, dismantle and clean the suction pipe and
remove any foreign material in the Cavitator.
Checking the Cavitator body for foreign material
5.1
Remove the Cavitator housing as described below. The assembly
drawing is to be used for reference.
1. Disconnect the power supply. Make sure it is locked out using a
locking device for which only the person involved in the maintenance
procedure has possession of the key.
2. Remove
the
Cavitator housing
by undoing the body screws and
carefully pull off the
Cavitator housing
.
3. Turn
the
rotor
to ensure that there is no foreign material behind it and
in the holes
4. If there is any foreign material in the Cavitator, remove it.
5. When the Cavitator body is clean and free of foreign material,
reassemble the Cavitator. Mount the Cavitator housing as described
below.
6. Press the Cavitator housing carefully over the O-ring without
damaging it, and fasten the housing screws, observing the correct
tightening torque:
M8: 30 Nm (22 lbf/ft)
M10: 45 Nm (33 lbf/ft)
M12: 74 Nm (53 lbf/ft)
7. Install suction and discharge pipes. Check that the pipe unions have
been tightened properly and that pipe supports have been fitted.
8. To make the Cavitator housing easier to fit, we recommend that you
give the O-ring a thin layer of food-approved, acid-free grease or
soap.
Testing the Cavitator
5.2
To check the Cavitator, pour water into the double mechanical shaft seal
and start it for a moment. Check the direction of rotation (Figure 3).
Listen for any unusual noises.
Never let the Cavitator run without liquid in the double mechanical shaft
seal as it will ruin the shaft seal.
