Operating Modes
Interval mode
Press the "ON/OFF" button. The control display initially displays the system version, the serial
number of the unit and the software version number for 3 seconds. Upon start up, the control system
switches automatically to the "Interval" mode (see "Interval mode" on page 66). In the "Interval"
mode, the water is recirculated at regular intervals to maintain a constant quality of the pure water
and prevent any growth of bacteria. Ultrapure water cannot be dispensed from the unit and TOC
readings are not available during this time. The "UV" text in the display indicates that the UV lamp is
on. If the measured values are temperature-compensated, this is indicated by "TC" in the display.
The pure water measured values and temperature are also indicated. Messages and measured values
are displayed regardless of the active operating mode.

switches into the "Interval" mode. After 35 sec. the system is going to be rinses the ultra filter.
The display shows:
Normal mode
NONSTOP mode
The control system switches the unit to the "Nonstop" mode when the "NONSTOP" button is
pressed. The "Nonstop" mode is the only mode in which pure water can be taken from the tap. The
"Nonstop" mode ends automatically at programmed intervals e.g. after 2 hours, or when you press
the "INTERVAL" button. The unit then continues to operate in the "Interval" mode. The message "UV"
is displayed when the UV lamp is switched on. The UV lamp can only be switched on/off in the
"Nonstop" mode (see "UV lamp" on page 67). The TOC value is also only displayed in the
"Nonstop" mode, with the UV lamp switched on.
