The pumping height can be regulated by means of the float
switch (
4
) and its position in the float switch locking device (
3
).
Please observe the following information regarding the float
switch (
4
):
•
Make sure that the float switch (
4
) always has enough
clearance and is not permanently activated. This could
prevent the automatic switch-off causing the device to run
dry. This would damage the pump.
•
Make sure that the float switch (
4
) is able to move freely
and does not suffer from a limited mobility caused by
obstacles.
•
Observe a sufficient distance between float switch (
4
) and
float switch locking device (
3
), for this could prevent the
automatic switch-off causing the device to run dry.
•
Make sure that the position of float switch (
4
) is adjusted in
a way, that it does not lie flat on the ground. This could
prevent the automatic switch-off causing the device to run
dry.
If required, lock the float switch (
4
) by means of the float switch
locking device (
3
). To do so, push the float switch locking
device (
3
) from above into the respective holder on the housing
with the float switch (
4
) pointing downwards. In order to adjust
the desired pumping height, insert the cable of the float
switch (
4
) through the float switch locking device (
3
).
