MAINTENANCE AND CLEANING
It is absolutely essential to prevent any risk of the pump freezing. In the event of freezing temperatures, remove
the pump from the liquid, empty it and keep it in a place where it cannot freeze. The pump must be disconnected
from the mains power supply before any cleaning operation is performed.
The pump is maintenance free.
5. TROUBLESHOOTING
Before taking any troubleshooting action, disconnect the pump from the power supply.
If there is any damage to the power cord or pump, any necessary repairs or replacements must
be handled by the manufacturer or his authorized customer support service, or by an equallyqua-
lified party, in order to prevent all risks.

Solution
1) Check if power is supplied to the socket
and that the plug is correctly inserted.
2) Remove the plug from the power socket
and insert a screwdriver into the notch on
the shaft (from the cooling fan side) and
unblock it by turning the screwdriver.
1) Stop the pump, unscrew the delivery
pipe, shake the pump and suction hose to
remove any air bubbles. Top up with water,
connect the hose ensuring it is correctly
sealed and start the pump again.
2) Check that the joints of the suction
hose have been performed correctly.
Make sure there are no counterslopes,
traps, goosenecks or constriction on
the suction pipe and that the foot valve
is not blocked.
3) - place the suction valve in water
- clean the foot valve
- clean the suction basket
- check the suction depth.
