Radiation chamber
The high level of effectiveness is achieved by ensuring that each volume element receives the required UV
dose when it flows through the radiation chamber. Furthermore, the radiation field and hydraulic conditions
inside the radiation chamber are tuned to one another.
A UVC lamp is installed axially inside the radiation chamber. The low-pressure lamp is a pressure-tight
pressure tube made of UV-permeable quartz glass that is closed on one side. Both the UVC lamp and quartz
tube can be replaced in just a few easy steps when carrying out maintenance work.
The UVC lamp is fully enclosed ensuring that no UV light can escape the UV chamber during normal
operation. This ensures that operating personnel are not exposed to any risk.
The radiation chamber can be vented at the top (model JUV 35-50 only) and drained at the bottom (model
JUV 35-110 G/GS only). To clean and in the case of model JUV 10-110 GS inspect the UV sensor, flow must
be interrupted using shut-off valves previously installed by the customer upstream and downstream of the
JUDO UV disinfection system. In addition, the complete radiation chamber must be drained.

Installation
Attention
A sufficiently sized floor drain (in accordance with DIN EN 12056) must be installed at
the place of use for the eventuality that leaking of the JUDO UV disinfection system or
its feed pipe could result in extensive damage!
Additionally we also recommend that the water is shut off if personnel are present in the
vicinity of the UV disinfection system!
Assure yourself that prior to connection of the pipes no impurities can enter the UV
disinfection system from the pipe system (e.g. residues from installation work)!
Accordingly cleaning of the entire new installation may be necessary!
5.1
Requirements for the place of installation
The UV disinfection system must be installed in a dry, frost-proof location with a condensation-free
and non-aggressive atmosphere.
Ensure there is enough space available on all sides for installation, maintenance and repair work
and also for ready accessibility.
To install and remove the UVC lamp there has to be a clearance of at least 600 mm or
1,100 mm.
An adequately sized sewer connection in compliance with DIN EN 12056 must be fitted to ensure
that the rinse water discharged at certain time intervals or when a certain temperature is reached is
drained away without backing up occurring. The same applies to the draining of the radiation
chamber and bypass lines. The rinse and/or discharge lines must be of the same size as the rinse
