CLEANING
WARNING!
Before carrying out any works: disconnect the
pump and the controls from the mains and take
steps to ensure that no one else can reconnect
them to the power supply.
WARNING!
Check the mains cable for signs of mechanical
and chemical damage. Damaged or kinked ca-
bles must be replaced by the manufacturer.
NOTICE!
If the water contains high levels of iron
or lime, insufficient cleaning can result in irre
-
parable damage to the seal and thus also to the
pump motor in the long term. Consequently, the
pump must be cleaned at regular intervals ac-
cording to the hardness of the water.

QUICK TIPS FOR REM-
EDYING FAULTS
Pump does not work
•
Check mains current (do not use a pin gauge)
•
Fuse faulty = may be too weak (please refer to
Electrical Connection)
•
Mains supply cable damaged = repair to be
carried out by manufacturer only
Pump runs but does not pump
•
Empty the pressure pipe or hose to allow the
non-return valve to open and the air to escape
from the pump housing, it may be necessary
to carry out a ventilation drilling
Impeller blocked
•
Solids and fibrous matter have become lod
-
ged in the pump housing = clean
Decreased pumping performance
•
Foot strainer obstructed = clean
•
Pressure pipe obstructed = clean
•
Rotor worn out = repair to be carried out by
the manufacturer
