Setting the ON/OFF opera-
ting point
The ON and OFF operating point of
the float switch can be set by adju-
sting the float switch in its latching
holder.
Before you put the pump into opera-
tion, please check the following:
●
The float switch must be installed
so that the level of the ON opera-
ting point and the level of the
OFF operating point can be rea-
ched easily and with little force.
To check this, place the pump in
a vessel filled with water, raise
the float switch carefully by hand
and then lower it again. As you
do so, note whether the pump
switches on and off.
●
Make sure that the distance bet-
ween the float switch head and
the latching holder is not too
small. Proper operation is not
guaranteed if the gap is too
small.
●
When you set the float switch,
make sure that it does not touch
the base before the pump swit-
ches off. Caution! Risk of dry-
running.
