2.3 Safety Devices
Label on radiation chamber
UV-C
CAUTION! Dangerous ultraviolet radiation
o UV-C radiation is harmful to the eyes and skin! Place the UV lamps into operation only in
their installed state! Install the UV system in accordance with regulations and instructions
before starting up the UV lamps!
CAUTION: Danger
Disconnect power plug or switch off the system at the master switch before performing
any maintenance work. Depressurise radiation chamber before performing maintenance
work.

WARNING SYMBOL
CAUTION: UV-C radiation
Label on control cabinet
Disconnect power plug or switch off the system at the master
switch before opening.
In the case of emergency
In the case of emergency, switch the red/yellow master switch (if provided) on the side of the
control cabinet to OFF.
If the system has no master switch, disconnect the power plug!
If the master switch has no effect, disconnect the power plug! (The master switch does not
disconnect the entire system from the power supply.)
3 Function
The water to be treated flows through the stainless steel radiation chamber past the UV lamps.
The UV radiation kills the germs and destroys substances such as chloramines in swimming pool
water.
Operating with high efficiency, the UV low-pressure UV lamps used produce UV-C radiation of
the wave length 254 nm which is particularly effective for disinfection and sterilisation purposes.
The UV lamps are located in protective tubes made from high-grade quartz with high UV
permeability.
The compact design of the radiation chamber, the optimised flow as well as the fitted turbulators
ensure uniform radiation of the entire flow of water.
In connection with the UV-C sensor, a control system monitors the UV system.
Start-Up The UV lamps are ignited after switching on the Dulcodes UV system.
In multi-lamp systems with a data bus to the ballast units, the bus is activated prior to ignition.
This procedure can take several seconds depending on the size of the system.
After ignition, the lamps require several minutes until they reach operating temperature.
The UV-C sensor monitors the UV lamps: The flushing valve for start-up flushing opens as soon
as the UV-C output exceeds the safety threshold.
The flushing valve also opens if the safety threshold is not reached within the maximum
permissible warm-up time. If the safety threshold is still not reached within the maximum clear
flushing time, the control will shut down the UV system and assume flow mode.
