COMMISSIONING AND OPERATION
Note: Long enough and strong ropes should be attached to the handle
before the first use. When the pump is immersed into the liquid, the rope
along with a handle can be used to balance the pump.
After you have read these installation and operating instructions carefully, you
can put your new pump into operation by observing the following points:
•
Check that the pump rests on the ground.
•
Check that the pressure line has been properly installed.
•
Make sure that the electrical connection is 230 V ~ 50 Hz.
•
Check the proper condition of the electrical outlet.
•
Make sure that moisture or water never reaches the mains connection.
Note: The pump must not run dry! When setting the float switch, make
sure that it does not touch the ground before switching off the pump.
Check the functionality of the float switch
The switch-on or switch-off point is determined by the height of the water
level. The switching differential can be set universally by lengthening or
shortening the float cable. The integrated float switch is already set so that the
pump can be operated immediately. If you use the pump stationary, you must
check the function of the float switch regularly, but at least every 3 months.
•
You must position the float switch so that you can reach the switching
point heights „On" and „Off" with relatively little effort. To check this, place
the pump in a container filled with water and carefully lift the float switch
by hand and lower it again. The pump must switch itself on or off.
•
Always ensure that the distance between the head of the float switch and
the float switch grid is not too small. If the distance is too small, proper
operation cannot be guaranteed.
•
When setting the float switch, also make sure that it does not touch the
ground before switching off the pump.
