If the electropump is not going to be used for a long period of time (i.e. one year), it is advisable to empty it completely
(by opening the drain cap, see Fig. 1 n. 10), rinse it with clean water and store it in a dry location, where it can be
protected from frost.

POSSIBLE CAUSE
1) No power.
2) Motor protection tripped.
3) Defective condenser.
4) Shaft blocked.
5) Pressure switch installed
incorrectly or damaged.
1) Empty pump body.
2) Air inlet from the suction pipe.
3) Suction height above the height
recommended for the unit.
1) The power supply does not
comply with the data on the
nameplate.
2) A solid object is blocking the
impellers.
3) The liquid is too thick.
4) The liquid or the environment are
too hot.
1) The tank membrane is
damaged.
2) No compressed air in the
tank.
3) The foot valve on the suction
pipe is blocked and not
appropriately sealed.
1) The pressure required to stop
the pump pre-set on the
pressure switch is too low.
2) Air inlet from the suction pipe.
1) The maximum adjustment
of the pressure switch is too
high.
2) Air inlet from the suction
pipe.
1) Verify that voltage is present and that the plug has
been correctly inserted.
2) Determine the cause of the problem and reset the
switch. If the thermal switch has been enabled,
wait for the system to cool down.
3) Contact the Customer Assistance Service.
4) Verify the cause and unblock the electropump.
5) Contact the Customer Assistance Service.
1) Stop the pump and fill the body with water using
the filling cap (fig. 1, n. 9).
2) Verify that: a) the joints are sealed - b) the fluid
level has not lowered below the foot valve - c) the
foot valve is sealed and not blocked - d) there are
no siphons, bends, counter-slopes or throats along
the suction pipes.
3) Check and reduce the suction height or use a
device with more suitable characteristics.
1) Check the voltage on the power supply cable
leads.
2) Disassemble and clean the electropump.
3) Dilute the pumped fluid.
4) Remove the cause of the problem, wait for the
pump to cool down and restart it.
1) Have the membrane or tank replaced by qualified
personnel.
2) Fill the tank with air using the delivery valve and a
maximum pressure of 1.5 bar.
3) Disassemble and clean the valve or replace it when
necessary.
1) Contact the Customer Assistance Service.
