Important Note!
If the mains cable or plug suffers any damage from external action, repairs to the cable should
be serviced by a qualified specialist using only standard spare parts. This will ensure that it
meets the required safety standards.
7 SETTING TO WORK
After having read these instructions carefully, you can set your pump to work, reconsidering
the following:
▪ Check if the pump rests on the ground of the shaft.
▪ Check of pressure cord has been attached properly.
▪ Check if electrical connection is 230 V - 50 Hz.
▪ Check if socket is in good condition.
▪ Make sure that water and humidity can never come to the mains supply.
▪ Avoid pump running dry.
7.1 Venting the pump before use
▪ Always ensure that the pump is vented properly before commissioning the pump. Possibly
tilting back and forth several times until no more air bubbles appear, wait at least 15
seconds before the pump to start.
7.2 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.
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.
