Cleaning of the impeller (U5 and U6)
To clean the impeller, and in the event of an
obstacle or blockage, the foot strainer must
be levered off. After this, take out the screws
on the underside of the pump and remove the
cover. The impeller can now be cleaned.
Worn impellers can have sharp edg-
es.
If the pump performance decreases, the im-
peller must be checked for wear and replaced
by the manufacturer if necessary.

QUICK TIPS FOR REMEDYING
FAULTS
No pump operation
• 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
lodged 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
• Wrong direction of rotation (for a three-
phase current) = ask a qualified electrician
to change 2 phases of the supply line
