System Menu
6.3.2 Limit Values
Under Menu r Settings r Limit values, you can define the minimum requirements
for ultrapure water. If the set conductivity limit value is exceeded (unit: μS/cm) or
below the range (unit: MOhmcm), your arium
®
pro system issues a warning message.
The following limit value can be set in the Limit values menu:
Factory settings Adjustable range
LFP - conductivity of the ultrapure water
10.5 MO*cm
0.095 μS/cm
1 – 18 MO*cm
1 – 0.055 μS/cm
The limit values are set in the unit of measure configured under Displayed values.
The limit values apply to the compensated conductivity values. If displayed values
are selected in the menu without a compensated conductivity display, this may
be the reason for the warning “Limit value exceeded” being issued despite the
uncompensated value being located within the permitted range.
6.3.3 ECO Mode
For economic and ecological operation of the system, we recommend that you
switch the arium
®
pro system to Eco mode when no water is being dispensed. The Eco
mode guarantees high water quality even during longer periods of inoperation of
the system. In the Eco mode, the water in the system is recirculated every hour for
15 minutes.
The Eco mode can be activated manually and automatically. A dark, empty display
and a yellow backlit Eco/Home key indicate that the Eco mode is activated.
Manual Activation
t In the operating mode, press and hold the Eco/Home key for at least three
seconds.
Automatic ECO mode
− The Eco mode can be activated automatically after the automatic ECO time has
elapsed. The time starts following the last operating process.
− Under Menu r Settings r Eco mode, set the Eco time.
− If you enter a time of “0 hours 00 min”, the automatic ECO mode is deactivated.
− The maximum Eco time is 9 hours 59 minutes.
