9. Setting the ON/OFF switching point
Automatic operation:
The activation and deactivation points can be
adjusted infinitely by securing the floating cable to the
handle (Fig. 2 / Point 6) on the machine.
The switching differential can be infinitely adjusted by
extending or shortening the floating cable.
Before you put the pump into operation, please
check the following:
● The float switch must be installed so that the level
of the ON operating point and the level of the OFF
operating point can be reached 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 between 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 switches
off. Caution! Risk of dry-running.
Manual operation:
Mount the float switch as illustrated in Figure 3. The
pump is in constant operation.
