NOTE
The rinsing valve should be large enough to ensure adequate rinsing of the system. Set
the maximum water temperature in the display sufficiently lower than the maximum value,
displayed at the bottom line to prevent the maximum temperature from being reached
during the rinsing process.
Displayed as max. value in the display depending on the system design.

Maximum Rinse Duration Following a Temperature Rise

Maximum
rinse duration
xx min
If the maximum water temperature does not fall by approximately 5 °C during the rinsing
period, the control system switches the lamp off and reports a fault. Please also refer to
section 4.3.13.

Setting the Start Rinse Duration

Start rinse
duration
1 min
The start rinse duration is designed to ensure that the consumer receives only perfect water.
After ignition, as soon as the UV lamps have reached the operating temperature and the sensor
signal has exceeded the safety threshold, the automatic rinsing valve (if there is one) opens for
the start rinse duration. The stop valve does not open until after that.
NOTE
A start rinse duration of 1 minute is usually adequate. If the system does not have a
rinsing valve, the duration of the start rinse duration can be set to 0 minutes.

Setting the Maximum Free Rinse Duration

Max. rinse duration
xx min
The free rinsing phase is used primarily for the disinfection of drinking water. A maximum free
rinsing period of over 10 hours is often used in this application. If there is such deterioration in
the UV transmission when using water that has low natural filtering properties, after heavy
rainfall for example, that the UVC sensor signal falls below the safety threshold, the stop valve
closes and the flushing valve opens. When the water quality improves, the UV disinfection
system returns to normal operation. If the UVC sensor signal does not rise above the safety
threshold during the maximum free rinse duration, the UV disinfection system reports a fault.
