Pumping out any remaining liquid
Before you can pump out any remaining liquid be-
low the cut-off (= STOP) level (see technical data),
you will have to operate the float switch manually:
• Unplug the electric cable.
• Fix the float switch so that it remains in an up-
right position.
• Plub in the electric cable. The pump will automa-
tically switch on and pump out any remaining li-
quid.
While pumping out remaining liquid, make
sure to keep the pump under observation and
turn it off by pulling the plug when the liquid has
been completely pumped out, so that the pump does
not suck air, as this may damage your pump.
If the level of the remaining water drops
below 5 mm (TSE), 30 mm (SPE), 45 mm
(BVP), the pump will suck air. Before using the
pump again to drain liquid, the air trapped in the
pump will have to be let out (see Setting up and
Operating the Pump).
Adjusting the cut-in and cut-off levels
The float switch cable is attached to the pump hou-
sing. You can adjust the cut-in = START and cut-off
= STOP levels for operation by simply changing the
height of the switch as desired. Recommended length
of the float switch cable is approx. 120 mm.

AINTENANCE AND LEANING
Before beginning any maintenance or cleaning
work, make sure that the pump has been
unplugged and take precautions to ensure that it
cannot be switched on during work!
Cleaning the pump
– If you have used your pump to pump chlorine water
(pool water) or liquids which leave a residue, flush
your pump out with clear water after use.
– Clean the suction slots located in the suction body
with clear water as required.
Protect from frost
Your pump is susceptible to low temperatures. Make
sure to empty the pump of residual liquid and store
it so that it is protected from frost.
