Remedying Faults - Jung Pumpen U3 K Originalbetriebsanleitung

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.
CAUTION!
Worn impellers can have sharp edges.
If the pump performance decreases, the impel-
ler must be checked for wear and replaced by
the manufacturer if necessary.

QUICK TIPS FOR

REMEDYING 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
• Wrong direction of rotation (for a three-pha-
se current) = ask a qualified electrician to
change 2 phases of the supply line
for A2 screw materials
