Installation of low level probe (option)
Put the level probes in their respective product container.
The existing hoses connected to the pump-stand shall be replaced with the new hoses. Connect the hoses to the left
side of each pump on the pump-stand as before.
The cable (A) shall be connected to the Jetsave control unit and the hose (B) shall be connected to the pump-stand.
The level probes are fitted with a magnetic float switch (C). This switch should arrive in the correct position for your
application.
Should the switch work in reverse, remove the cross head screw securing the float magnet, remove the float magnet
and refit it in the opposite direction.

Connection with low level sensors/probes
Open the Jetsave control unit before connection.
If low level sensors are installed, an error message will be displayed when any of the chemical tanks are low. The
program will however continue. As the A122 board is with 5 outputs for pumps but only 3 inputs for level sensing,
some low-level sensors must be connected in parallel. In such an installation the control system will be alarming low
level when any of merged sensors has triggered. The figure below is showing such a configuration.
