Slowly open shut-off valve upstream of radiation chamber
Fill radiation chamber until water emerges at the vent screw
Close vent screw; only slight force is required for this purpose
Open shut-off valve downstream of radiation chamber
(necessary only for manual shut-off valve)

IMPORTANT!
For radiation chambers that are regularly cleaned by filling with a cleaning solution, it is
recommended to replace the water drain screw and vent screw by suitable valves.
It is advisable to use a suitable acid-resistant pump to fill larger radiation chambers via the
water drain opening.
If the radiation chamber is filled using a pump, it is advisable to circulate the cleaning
solution via the vent opening. This will shorten the cleaning time and improve the results.

Changing UV lamps
ATTENTION!
The UV lamps should be renewed at the latest when
• the sensor signal approaches the safety threshold provided there are no other causes
such as coating formed on the lamp protective tubes or a substantial deterioration in
UV transmission;
• the operating period of the UV lamps approaches or exceeds the maximum useful life of
the lamps.
Do not touch the glass of the UV lamps with bare hands!
Fingerprints burn into the glass and can cause premature failure. Before fitting the lamps, remove
fingerprints with a cloth moistened with alcohol!
WARNING!
• Switch off the master switch or disconnect the power plug before installing and
connecting the UV lamps!
• UV-C radiation is harmful to the eyes and skin!
Place the UV lamps into operation only in their installed state!
Install the UV disinfection system in accordance with regulations and instructions before
starting up the UV lamps!
• Do not change/modify the lamp connection cables already fitted!
• Do not change/modify the distance between the connector and lamp cover!
Otherwise it will not be possible to ensure that the lamp rests against the closed end of
the protective tube. This position, however, is the prerequisite for safe and reliable
disinfection!
IMPORTANT!
Clean the protective tubes every time the UV lamps are replaced!
For multi-lamp systems: All UV lamps should be replaced in the event of a lamp failure at
the end of the maximum useful life!
Systems without connector on UV lamp cover
