General cleaning instructions
• In case of transport for utilization in
different locations, the pump must be
cleaned with clear water after every
use.
• In case of stationary installation, the
function of the float switch (
7) is
to be checked regularly (at the latest
every three months).
• With a water jet, remove fluff and
fibrous particles which are possibly
present in the pump casing.
• Regularly remove sludge from the pit
base and also clean the shaft walls.
• Clean precipitation from the float
switch with clear water.
• In the case of a long period of non-use,
the pump must be thoroughly cleaned
after the last use and before the new
use, since difficulties in start-up can
arise due to precipitation and residues.
Replacing the backflow
preventer
Replace a faulty backflow preventer (see
“Spare Parts/Accessories”).
1. Unscrew the reducer (9) on the
angle adapter (10) and take out
the backflow preventer (12) and

2. Insert the seal (12b) in the new
backflow preventer (12a).
3. Insert the backflow preventer (12)
between the angle adapter (10)
and reducer (9) in such a way that
the valve opens in the direction of
flow and closes against the directi

on of flow.

ler, this can be cleaned via the pump outlet
(3) or by removing the floor plate (4):
1. Unscrew the bracket adapter

(
3).
2. Remove the 3 screws on the bot-
tom of the base (5) and take off
the base plate (4).
3. Clean the fan wheel using clean
water.
4. To re-assemble, reverse this order.
Any measures above and beyond these,
particularly opening the equipment, are
to be carried out by an electrician. In the
case of repairs, always contact our service
centre.
