7 Operation
As soon as the pump is connected to the supply voltage, the LEDs in the control panel indicate
which level is set.
For level 1 – the first LED lights up, for level 2 – the first and the second LED light up,
for level 3 – all three LED's light up.
By pressing the button, the levels are switched through continuously.
The pump can be optimally adapted to the system by selecting of the most suitable
characteristic curve. Flashing LEDs signal a fault.

8 Assembly
The circulation pump is installed in the pipe, usually directly in front of the service water storage
tank, and in such a way that the water is pumped back from the central tapping point into the
storage tank via the circulation pipe. A check valve must be installed on the pump's discharge
side (primary side) to prevent pump backflow when the tap is opened. A shut-off valve is
installed at the suction point (secondary side) of the pump to simplify maintenance.
A voltage-free assembly must be carried out with the horizontally positioned pump motor
(the direction arrow on the pump body indicates the flow direction).
When carrying out thermal insulation works, make sure that the pump motor and the
electronics housing are not insulated.
