START-UP
Once all the aforementioned operations have been completed, the pump is ready to be started.
Priming
Start the pump
-
- Open the priming connector by turning the knob in an anticlockwise direction and wait for liquid to come out of the pipe
connected to it.
Once you are sure that the pump is completely full of liquid, you can close the connector and the pump will begin to dose.

Solution
Clean the valves or replace them if it is not
possible to remove the build-ups
Position the pump or tank so as to reduce the
suction height (pump under water head)
Reduce the suction height or use a pump with
a bigger flow capacity
Check that the ring nuts are properly tightened
Use a pump with a bigger flow capacity or
reduce the suction height (pump under water
head)
Clean the valves or replace them if it is not
possible to remove the build-ups
Check the injection valve installation. Insert a
back-pressure valve if insufficient.
Use an opaque PE pipe on delivery
Check the pump flow capacity relative to the
system pressure.
Check the system pressure. Check whether
the injection valve is blocked. Check whether
there are any blockages between the delivery
valves and the injection point.
Check the presence of the foot filter (valve).
Use a level probe that stops the pump when
the chemical product in the tank has run out.
If the membrane has been replaced, make
sure that the same is correctly tightened.
Check whether the
corresponds to that of the electricity network.
