Hydraulic Connections
ATTENTION!
• Make the hydraulic connection of the radiation chamber in accordance with valid
general guidelines as well as the locally applicable installation regulations.
• Use UV-resistant material for the hydraulic connection!
If PVC is used, it is possible that the PVC material may discolour in the area of the
connection and even turn brittle under unfavourable conditions.
• In applications with demanding disinfection requirements (e.g. drinking water
disinfection) without facilities for interrupting the water flow in the case of fault/
malfunction (e.g. shutting down the delivery pump):
Fit an automatic shut-off valve downstream of the radiation chamber and connect to the
control!
The automatic shut-off valve must close automatically to ensure the flow of water is
interrupted also in the event of power failure.
IMPORTANT!
• Fit valves upstream and downstream of the radiation chamber for the purpose of
shutting off the radiation chamber when performing maintenance and servicing work!
• Fit suitable stopcocks upstream and downstream of the radiation chamber for the
purpose of taking microbiological samples!

Control Cabinet and Control
5.2.1
Installation
The control cabinet and/or the carrier panel with the control and ballast are to be mounted on
the wall or a suitable frame such that the lamps and sensors can be connected with the cables
provided.
ATTENTION!
The lamp connection cable and the sensor cable must not be extended!
5.2.2
Electrical Connections
Electrical installation must be performed by an authorised electrician using the supplied
documentation and diagrams (circuit diagram).
ATTENTION!
• Comply with the valid general guidelines as well as the locally applicable installation
regulations!
• Perform installation work only with the power supply to the system disconnected!
• Connect the PE conductor to the radiation chamber!
• The lamp connection cable and the sensor cable must not be extended!
5.2.3
Opening Control Unit
Electrical installation must be performed by an authorised electrician using the supplied
documentation and diagrams (circuit diagram).
ATTENTION!
Before opening, make sure that no voltage is applied to the control unit!
Undo the 4 screws at the top of the housing
Open the housing:
for this purpose exert pressure with the index finger on to the front edge of the housing
while simultaneously pulling forward so that the catch hook disengages
Carefully pull the upper section forward away from the lower section (both sections are
connected by a ribbon cable!)
Fit the upper section with both guide rails in the approx. 80 mm high plug-in slot
All connection terminals are now freely accessible. Blanked off holes that must be broken
out to insert the connection cables are provided on the underside of the control unit.
The openings in the rear row are intended for PG-11 screwed glands.
The 5 openings in the front row are intended for PG-7 screwed glands.
