Function
The water to be treated flows through the stainless steel radiation
chamber past the UV lamp. UV radiation kills the germs and
destroys substances, like chloramines, in the swimming pool water.
The UV medium pressure lamp produces UV-C radiation. The UV
lamp is located in a quartz lamp protection tube with good UV
transparency.
The design of the radiation chamber and the flow of radiation
deliver even irradiation of the entire flow of water.
A control monitors the UV system in conjunction with the UV
sensor.
Shut-off valves and rinse valves do not form part of
the scope of delivery
The shut-off valves and rinse valves do not form
part of the scope of delivery of the UV system and
are provided by the operator on site.

5.1 Commissioning
Once the UV system has been switched on, the UV lamp is ignited.
Following ignition, the UV lamp requires approximately 1 ... 3
minutes until it has reached its operating temperature.
If the safety threshold is not exceeded within the maximum permis‐
sible warm-up time, the controller switches the UV-system off and
goes into fault mode.
The UV-C sensor monitors the UV lamp: As soon as the UV output
has exceeded the warning threshold, the rinse valve opens for the
start rinse.
After the start rinse, the shut-off valve opens and the UV system
starts normal operation.
