Check this by placing the pump
into a vessel filled with water
and lift the float switch (
6)
carefully by hand and then low-
er it again. In this case, you can
see whether the pump switches
on and off.
- Also ensure that the separation
distance between the float switch
(6) head and the float switch
height adjustment (5) is not too
small. In the case of a separa-
tion distance which is too small,
trouble-free functioning cannot
be guaranteed.
- During the adjustment of the float
switch (
6), ensure that the
float switch does not contact the
floor before the pump switches
off.
The pump run dry if too long a
float switch cable (
3) is chosen,
particularly if the float switch height
adjustment (
5) is not installed
(see „Operational start-up“).
Manual mode/flat suction
In manual mode, the pump does not switch
off automatically, as the float switch (
6)
is bypassed.
Position the float switch (6) vertical
-
ly upward in the float switch height
adjustment (5).
Monitor the pump constantly when
in manual mode. Switch the pump
off immediately (disconnect from
the mains) if no more water is be-
ing pumped. There is a risk of dam
-
age if the pump runs dry.
Maintenance and
Cleaning
Clean and maintain your equipment regu-
larly. This will guarantee its performance
and long durability.
Ask our service centre to car-
ry out any work that is not
described in these instruc-
tions. Use only original parts.
There is a risk of injury!
Pull out the power plug before
every maintenance operation. There
is a risk of electrocution or of injury
from moving parts.
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
(
6) 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 (
3).
• Clean precipitation from the float
switch (
6) with clear water.
• Regularly remove sludge from the pit
base (at the latest every 3 months) and
also clean the shaft walls
To replace the backflow stop
Replace a defective backflow stop (see
“Replacement parts/Accessories”).
