In the even that the pump is often transported in the course of operation, it should be cleaned out with
clear water after every use.

In case of stationary installation, the function of the floating switch should be checked every 3 months.

A water jet should remove all fibrous particles, which may have built-up inside the pump housing.

Every 3 months the shaft ground and as should be cleaned from mud.

Setting the ON/OFF operating point
The ON and OFF operating point of the float switch can be set by adjusting the float
switch in its latching holder.

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 not touches the base before the pump switches off.
Caution
！
Risk of dry running.
