Flushing device
The pump can keep the intake section at the bottom of the
chamber clear of deposits to a large extent if you carry out a
small modification: Lever off the foot strainer with a screwdriver,
unscrew the three red caps and snap the foot strainer back on.
This reduces the performance of the pump only insignificantly.
Low level pumping
Flooded surfaces can be drained down to a residual water level
to approx. 5 mm without using any special accessories. To do
so, the foot strainer must be levered off with a screwdriver. In
the case of pumps with an attached control, the float switch
must be locked in the ON position. It is not possible therefore
in low level pumping to operate the pump in switching mode. To
make the pump operate, the drainage hose must be emptied be-
fore each pumping run and there must be a 40mm minimum water
level available.
If the pump is malfunctioning, part of the contents of
NOTICE!
the oil reservoir could escape into the pumping medium.
The floats of the level controller and alarm system (ac-
NOTICE!
cessory) are installed so that they are freely movable but not
under the inlet. Please observe the minimum distances, see
installation example. The controls may only be installed in a dry
and well ventilated room!
CAUTION!
For safety reasons, mobile operation is only allowed vertically
and with a foot strainer!
If a hose is used as a pressure line, care must be taken to en-
sure that for every pumping operation the hose is completely
empty before the pump is submersed. Any residual liquid would
obstruct the ventilation of the pump housing and therefore
also hinder the pumping operation. For the same reason, the
pump would not operate if it was switched on before being sub-
mersed.
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 cables must be replaced by the
manufacturer.
If the water contains high levels of iron or lime, insuf-
NOTICE!
ficient cleaning can result in irreparable damage to the seal
and thus also to the pump motor in the long term. Consequent-
ly, the pump must be cleaned at regular intervals according to
the hardness of the water.

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 Con-
nection)
• 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 val-
ve 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
