Setting the ON/OFF switching point
o
The ON/OFF switching point can be infinitely adjustment facility. For this purpose you
must first slacken the screw. The switching differential can be infinitely adjusted by
extending or shortening the floating cable.
o
Before you put the pump into operation, please check the following:
o
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.
o
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.
o
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.
