Start-up and Operation

Preliminary checks before start-up of the pump
Do not start-up the device in case of damaged parts.
Make sure the coupling with the pump shaft turns freely when rotated by hand.
Make sure the screws of the coupling are tightened.
Make sure the coupling guard is fastened on the lantern bracket.
Make sure the shaft turns freely when rotated by hand.
For this purpose use the screwdriver notch on the shaft end ventilation side.

First starting

ATTENTION: never run the pump dry, not even for a short trial run.
Start the pump after filling it completely with liquid.
When the pump is located above the water level (suction lift operation, fig. 3A) or with a positive suction head
which is too low (less than 1 m) to open the non return valve, fill the suction pipe and the pump through the
priming hole (1) (fig. 4).
To facilitate this operation use a flexible tube (or elbow) and a funnel.

During filling, the needle screw in the drainage plug must be kept loose so as to allow a free passage
between the pressure chamber and the suction chamber (Fig.4a).
In case of horizontal installation (only for 50), arrange the screw upwards. The screw is both used for filling
and as air vent.

In the case of vertical installation, remove the plug (2) during the filling operation to vent the suction side.
After the liquid has been released, replace the plug (2). Proceed with filling until the liquid spills out of the
venting hole (1) in the upper cover. Top up until the pump is completely vented before replacing the plugs (1).
In the case of horizontal installation, fill and vent through the holes (1) in the pump casing.
