WARNING!
In the case of applications with stringent disinfection requirements (e.g. drinking water
disinfection), disinfect/sterilise the piping system, e.g. in a high-chlorinating process, prior
to initial operation!
This is particularly necessary in piping systems that have already been subject to soiling,
germs or micro-organisms.
6.1 Checking the Radiation Chamber for Leaks and Venting
➤ Open vent screw on radiation chamber
➤ Slowly open shut-off valve upstream of radiation chamber
➤ Fill radiation chamber until water emerges from the vent screw
➤ Close vent screw, only very little force is required
➤ Check radiation chamber for leaks
➤ Open shut-off valve downstream of radiation chamber
(necessary only for manual shut-off valve)
ATTENTION!
Use the clamping screw of the manual wiper as a vent screw if system is wall-mounted
vertically!
IMPORTANT!
Hand-tighten the clamping screw at the wiper rod only to such an extent that there are only
just no water leaks under operating pressure.
6.2 Switching On Disinfection System
ATTENTION!
Do not switch on the system before the radiation chamber is filled with water!
➤ Switch on master switch or connect power plug
➤ Check parameters in programming mode of the control system and change if necessary
(see 4.3 Operating Status)
ATTENTION!
Make sure that the UV lamps are operated at the standard current!
➤ Switch on UV system with the START/STOP key;
press the START/STOP key and hold for at least 2 seconds.
➤ If the control assumes the PAUSE state, operate the pause contact
After being ignited, it can take several minutes for the UV lamps to reach their full UV output.
IMPORTANT!
Observe the supplementary instructions for special applications, in which the sensor signal
is displayed in %.
6.3 Calibrating UV-C Sensor
The UV-C sensor is calibrated at the factory and does not need recalibration.
If recalibration is required, please send the system in to ProMinent.
IMPORTANT!
Observe the supplementary instructions for special applications, in which the sensor signal
is displayed in %.
All new UV lamps require a burn-in period of 100 to 200 hours. Therefore, check the safety
threshold and the warning threshold approximately 200 operating hours after commissioning
(start-up).
