e. Starting
-
Check that the pump is at the bottom of the well.
-
Check if the pipe is correctly fixed; diameter minimum 1 "1/4.
-
Make sure that the connection to the mains is never reached by moisture or water.
-
Do not allow the pump to run dry.
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.
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 putting 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.
