6. Operating the product
The lifting station is designed to operate
automatically according to the liquid level in the tank.
With a controller, you can easily change settings,
monitor the system or perform troubleshooting.
You can download the installation and operating
instructions for the controller with the following links
and QR codes.
6.1 Setting the start levels
The start level is closely related to the chosen inlets.
Choose a start level which will ensure a minimum
backflow in the inlet pipe, thus avoid risk of blockage
by sedimentation in the inlet pipe.
Set the start level as high as you can according to
your setup.
A high start level increase the tank effective volume
and decrease the numbers of start/stop of the
pumps.
The following illustrations show the allowed start
levels according to the inlet. Theses specific values
can only be selected with the LC 221 controller.
