• If the water does not come out after 3 minutes,
stop the pump and repeat the filling procedure.
• Once the pump has started, close the discharge
valve completely and then reopen it to ensure
that the maximum pump curve is reached; this is
reached with the priming valve closed.
• Check that the current consumed is less than or
equal to that indicated on the motor plate.
9. Maintenance
All maintenance work must be carried out by
authorised and qualified personnel!
WARNING! Risk of electric shock!
Danger from electrical current must be eliminat-
ed.
Before any electrical work, the pump must be
de-energised (switched off) and protected
against unauthorised restarting.
It is recommended to the disconnect the plug
rather than the male electrical connector (IPX4
preservation).
• No special maintenance required during opera-
tion.
• Keep the pump clean.
• If the pump is deactivated for a long period and
there is no risk of freezing, it is best not to drain
the pump.
• To prevent the shaft and the hydraulic compo-
nents from seizing up during periods of freezing
temperatures, drain the pump by removing the
plug (item 6) and the priming plug (item 5).
Screw back in the 2 plugs but do not tighten
them. Fill the pump and the piping before using
again.
NOTE: We recommend rinsing the pump after a
long period of deactivation.
