To prevent the level sensor from jamming
when mounted on a hose pipe, the mini-
mum distances from the float to the pump
casing (housing), shown in Fig. 3 and 4.
Fig. 3. The minimum distance from the
pump housing to the float.
Fig. 4. Minimum distance from pipe to float.
With the help of appropriate measures, care
should be taken that in the event of a mal-
function of the submersible pump, there is
no flooding.
Security:
■ Connect a hose (or pipe) with a diame-
ter at least equal to the diameter of the
pump outlet.
■ Make sure that the hose (or pipe) leaving
the pump is not blocked
■ Avoid dry running of the pump.
Switching the pump on:
A submersible pump must not suck in solid
particles. Sand and other abrasive substanc-
es contained in the pumped liquid destroy
the submersible pump.
1. Unwind the wire cable completely.
2. Ensure that all electrical connections are
protected from flooding and moisture.
3. Independently adjust the setting of
switching points of the float switch.
4. Secure the float switch cable to the pump
housing.
When working on a muddy, sandy or rocky
bottom, use suitable platform for installing a
submersible pump.
5. Slowly immerse the pump in the suction
fluid, making an angle of 45 degrees (to
reduce the amount of air trapped in the
pump casing).
6. If the pump rests on the bottom, make
sure it is on a flat and stable surface.
7. Insert plug into the socket outlet.
HANDLING
Automatic operation mode:
1. The submersible pump is automatically
switched on by the float switch when a
certain liquid level is reached, and when
the level is lowered, it automatically turns
off.
