CLEANING STORAGE MAINTENANCE
The pump does not require any maintenance. Frost can damage the pump. In very cold temperatures, remove the pump from the
liquid, empty it and store it away from frost. Before any cleaning work is carried out, the pump must be disconnected from the power
mains.
Once the pump has been removed from the liquid, it is advisable to clean the following parts with a simple jet of water:
- Filter (open, see figure 1A)
- Suction filter with float, in case of version X (see figure 3)
- Non-return valve. In this case, remove the part concerned as shown in figure 11.
Be sure to reassemble all parts correctly.

TROUBLESHOOTING
Before starting to look for faults it is necessary to disconnect the power supply to the pump (take the plug out of the socket). If the
power cable or any electrical part of the pump is damaged, the repair or replacement must be carried out by the manufacturer or
by their technical assistance service, or by a person with equivalent qualifications, so as to prevent any risk.
FAULTS
PROBABLE CAUSES
REMEDIES
The pump does not turn on or
does not stay on.
1. Pump is not powered
1. Check power supply
2.. No water
3. Restore the water level
The pump does not deliver water
1. The suction grid or the pipes are blocked
1. Remove the obstructions
2. The impeller is worn or blocked
2. Replace the impeller or remove the blockage
3. The head required is higher than the pump’s
characteristics
The flow rate is insufficient
1. The suction grid is partly blocked
1-2 Remove any obstructions
2. The impeller or the delivery pipe are partly
blocked or encrusted
Pump stops (possible tripping of
the thermal safety switch)
1. The liquid to be pumped is too thick and
overheats the motor.
1-2-3-4 Disconnect the plug and remove the cause
that caused the overheating, wait for the pump to cool
down and reinsert the plug.
2. The water temperature is too high
3. A solid body is blocking the impeller
4. Power supply not in accordance with data plate
values
