12. Clean the pump after each use, particularly after using it with muddy liquid. Secure the
pump against restarting. Before cleaning remove the motor protection plug and secure
the pump and the motor protection plug against accidental restarting and plugging.
Use a high-pressure cleaner first, to clean the pump and in particular the impeller. To
clean the impeller, turn the cleaning slot of
the impeller to the “12 o’clock position” so
that the cleaning slot is visible on the outlet
side of the pump (see image 2.2). Use the
high-pressure cleaner to spray directly into
the cleaning slot, to clean the impeller thor-
oughly. Then let the pump run for around
10 minutes in a basin with clean water. Fi-
nally, the pump must be completely
drained.
4.3 Series connection of CHIEMSEE pumps
To achieve pumping heights of over 12 m, series connection of CHIEMSEE pumps is pos-
sible. With this, the pressure side of the first CHIEMSEE is connected to the next
CHIEMSEE over a dimensionally flexible hose.
4.4 Low-level pumping
In normal operation, the liquid is pumped to the top of the intake nozzle. The pump then
intakes air and the pumping flow breaks off. To pump fluids up to a residual water level of
a few millimetres, the flat intake nozzle has to be mounted to the suction-side fixed coupling
(see Image 2a).
Caution CHIEMSEE H:
In case of high fluid temperatures of >80°C cavitation might arise during low-level pumping.
In this case the fluid has to be cooled with cold water.
If low-level pumping is to be carried out, the following points are to be observed:
1. Pump the medium according to section 4.2 of this user manual without flat intake nozzle
(with the intake nozzle facing upwards) until the pump intakes air.
2. Now switch the pump off and remove the motor protection plug. Secure the pump and
the motor protection plug against accidental restarting and plugging.
Danger from electric shock:
Only carry out work on the pump when the pump is disconnected from the network by
removing the motor protection plug from the power supply. Prevent accidental restart
and plugging of the pump and the motor protection plug by taking appropriate measures.
3. Now mount the flat intake nozzle to the suction-side fixed coupling. Use a coupling
spanner for this. Turn the curve clockwise until it is vertical and facing downwards (i.e.
up to the limit stop). Ensure that no stones or other hard objects, such as pond foils, can
be taken in!
4. Now plug the motor protection plug into the socket again and switch the pump on again.
5. If the flat intake nozzle gets stuck on solids, first turn
off the pump, then pull the motor protection plug and
remove the solids from the intake nozzle.
6. Pump the liquid until the pump intakes air. Switch
the pump off again.
As the intake nozzle reach until about 1 cm above the
ground, it is possible that there are still floating solids in
