5 Product description
This water treatment device is based on the principle of reverse
osmosis (mechanical filtration). Initially, the water passes through an
active charcoal filter that filters out chlorine and sediment. The water
is then forced at high pressure through several membranes, which
removes almost all of its mineral content.

Active charcoal filter (“Filter AC-M”)
IMPORTANT Never pick up the device by the filter cover (4).
5.2 Operating panel
Buttons for navigation within the menu
Info button (display of additional information)
Display
Device is ready for operation (stand-by mode).
The device is in AquaOpt mode ( 6.2) or produc-
es osmosis water ( 6.3).
A warning is present; however, operation is still
possible ( 9.1).
An error exists, the device no longer produces
osmosis water ( 9.2).
6 Operation
6.1 Switching on the device
Press the button.
The display then lights up green and the greeting text ap-
pears.
The device is automatically in stand-by mode.
INFO To maintain the membranes, automatic flushing takes
place every two hours in stand-by mode.
6.2 AquaOpt
This function guarantees that a specified water quality is available for
washing. Water that does not correspond to this quality is automati-
cally flushed into the drain. The water volume and the flushing time
depend on the device’s selected quality and the downtime.
During flushing, the display lights up blue and the following picto-
gram appears:
Optimisation
water quality
INFO Three different qualities are available (good, better, best).
The factory setting for quality is “better”.
Contact an authorised service technician if you want to change or
disable this function.
6.3 Production of osmosis water
As soon as the connected warewasher requests water, the device
first goes into AquaOpt mode. Then the production of osmosis water
begins. During this process, the display lights up blue and the follow-
ing pictogram appears:
6.4 Water quality display
After the device has produced osmosis water for at least 30 seconds
and production is finished, the water quality will be displayed for
several seconds on the display:
The more stars, the better the water quality (low conductivity). The
water quality depends on the condition of the membranes.
6.5 Switching off the device
To maintain the membranes, automatic flushing takes place every
two hours in stand-by mode. For this reason, the device must be
permanently connected to the electricity and water supply. When
required (e.g. overnight), however, the device can be switched off:
Press the button.
The display is not illuminated.

The device must be permanently connected to the electricity and
water supply.
