Precautions; Maintenance And Cleaning; Cleaning The Suction Filter; Cleaning The Impeller - DAB PUMPS P1 640 W Instructions Pour L'installation Et La Maintenance

9. PRECAUTIONS

RISK OF FROST: when the pump remains inactive at a temperature lower than 32 F, it is necessary to ensure that there
is no water residue which could freeze, causing cracks in the plastic parts.
If the pump has been used with substances that tend to form a deposit, or with water containing chlorine, rinse it after use
with a powerful jet of water in order to avoid the formation of deposits or encrustations which would reduce the
characteristics of the pump.

10. MAINTENANCE AND CLEANING

In normal operation the pump does not require any type of maintenance. In any case, all repair and maintenance work
must be carried out only after having disconnected the pump from the supply mains. When restarting the pump, ensure
that the suction filter is always fitted so as not to create the risk or possibility of accidental contact with moving parts.

10.1 Cleaning the suction filter


Switch off the electric power supply to the pump.

Drain the pump.

Clean with a jet of water and a brush.
11. TROUBLESHOOTING
Before taking any troubleshooting action, disconnect the pump from the power supply (i.e. remove the
plug from the socket). If there is any damage to the power cable or pump, any necessary repairs or
replacements must be performed by the manufacturer or his authorized customer support service, or by
an equally-qualified party, in order to prevent all risks.
