7. MAINTENANCE
Our pumps do not require maintenance. As a precaution, empty the pipes and any water from inside the pump
during periods of freezing temperatures.
If the pump is to remain idle a long time, dismantle the pump and store it in a dry, ventilated place.
WARNING: in the event of a breakdown, the pump should only be serviced by an authorized technical repair
center. When the time comes to dispose of the pump, it does not contain any contaminating or toxic material.
The main components are properly identified for selective scrapping.
8. Troubleshooting
1. The pump will not start.
2. The pump will not stop.
3. There is no suction from the pump.
4. Insufficient pressure or flow rate.
5. The motor overheats.
6. The pump starts and then stops shortly afterwards (klixon).
7. The pump starts and stops constantly.
