Commissioning
DANGER
Before commissioning the system, any pipework that transports the treated water should be
disinfected, e.g. with high chlorination, for applications in which high levels of disinfection
are required (e.g. the disinfection of drinking water). This is particularly important in
pipework where bacterial proliferation already exists.
6.1
Checking the Seals and Bleeding the Radiation Chamber
Open the bleed valve on the radiation chamber.
Open the stop valve in front of the radiation chamber slowly.
Fill the radiation chamber until water escapes from the bleed valve.
Close the bleed valve.
Check that the radiation chamber is sealed properly.
Open the stop valve after the radiation chamber (only necessary if it is a manual stop valve).
6.2
Switching on the UV System
IMPORTANT
The system must not be switched on until the radiation chamber is full of water.
Switch on at the mains.
Check the parameters in the programming mode of the control system and change them if
necessary (please refer to section 4.3 "Operating Status Displays")
IMPORTANT
Ensure that the UV lamp is operated at full capacity.
Press the START/STOP key to switch on the UV system. The START/STOP key must be held
down for at least 2 seconds.
If the control system adopts PAUSE status, activate the pause contact.
After the lamp has ignited, it takes approximately 1 minute to reach full capacity.
As the UVC sensor has not yet been calibrated, the safety threshold may not be exceeded
within the commissioning period and the maximum free flushing period causing the control
system to report a fault. In this case, carry out temporary calibration:
DANGER
Temporary calibration of the UVC sensor does not replace correct calibration after
commissioning.
Press the START/STOP key to switch on the system.
Calibrate the UVC sensor to 100 % within the commissioning period as described in section
6.3. It is not necessary to wait for a stable sensor value.
NOTE
Please follow the separate operating instructions enclosed for special applications that
require the sensor signal to be displayed in W/m
