Safety
CAUTION!
Exclude, by suitable means that in
the event of a fault in the immersion
pump, consequential damage is
caused by flooding.
 Make sure that the immersion
pump is standing securely or
operate the immersion pump
suspended from a rope.
 Make sure there is adequate
clearance under the pump.
 Never allow the immersion
pump to run against a closed off
pressure line.
 When using in shafts, make
sure the size is adequate.
 Always cover the shaft with a
secure footplate.
Switching the pump on
CAUTION!
The immersion pump must not draw
in any solid bodies. Sand and other
abrasive materials in the conveying
medium will destroy the immersion
pump.

completely.
2. Make sure that the electrical plug
connection is mounted in the area
safe from flooding.
3. Change the terminal position and
adjust the switching points of the
float switch (3) individually.
4. Attach the cable on the float
switch to the pump housing
securely.
➯ Recommended cable length on
the float switch approx. 120 mm
Use a suitable plate to ensure secure
mounting of the immersion pump on
muddy, sandy or stony ground.
5. Immerse the immersion pump in
the conveying medium slowly. Hold
the immersion pump at a slight angle
to allow any air to escape.

reached, and switches off again if the
water drops below the switch-off
height.
