MAINTENANCE
To ensure continued reliability of service, we recommend that
you take out a service contract.
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 cables must be replaced.
CAUTION!
Do not touch the pump until all rotating parts have come to a
standstill.
The foot strainer prevents coarse impurities from entering
the pump. Regular cleaning of the float and the foot strainer
to remove fibres and accumulations ensures optimum perfor-
mance and operation. To clean the impeller, the foot strainer
must first be levered off. The impeller can now be cleaned
through the suction opening.
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 the section
entitled Electrical connection)
•
Mains cable damaged = replace cable
•
Make sure that the pump is not switched on before the pump
is submersed.
•
Empty the pressure pipe or hose to allow the air to escape
from the spiral housing. The ventilation drilling described
can also be used for venting.
•
Check any pump controls
•
In the case of pumps with an attached control = the water
may be too low
Impeller blocked
•
Solids and fibrous matter have become lodged in the spiral
housing (please refer to the section entitled Maintenance)
Decreased pumping performance
•
Foot strainer obstructed (please refer to the section entitled
Maintenance)
•
Pressure pipe obstructed = clean
•
Rotor worn out = repair to be carried out by the manufac-
turer only
