Maintenance
NOTE
The connector can only be connected in certain positions. If necessary, turn the
connector by 90
°
and then try again.
왘
Insert the lamp fully into the lamp protection tube
왘
Mount the lamp cover on the bracket of the lamp protection tube using the knurled nut (only
tighten slightly)
왘
Slowly open the shut-off valve upstream of the radiation chamber
왘
Open the shut-off valve downstream of the radiation chamber (only required in case of
manual shut-off valve)
왘
Connect the mains plug
WARNING
Re-calibrate the UV C sensor after the installation of a new UV lamp!
It is only after a re-calibration that the operating safety of the UV disinfection system is
guaranteed.
7.3
Calibration of the UV C sensor
WARNING
•
Only a correctly calibrated UV C sensor guarantees sufficient disinfection.
•
When calibrating the UV C sensor, the water to be disinfected must flow through the
radiation chamber.
IMPORTANT
When calibrating the UV C sensor, a new UV lamp must be used and the lamp protection
tube as well as the sensor window must be cleaned.
NOTE
See also Chap. 6.2 “Switching on of the disinfection system“.
The UV C sensor is to be calibrated during commissioning as well as at each lamp replacement.
During calibration, the alarm threshold and the safety threshold are newly set. The operating
hours counter as well as the counter of the lamp activations are reset to zero.
Before calibration, the UV C sensor signal must be stable. A changing sensor signal shows that
the UV lamp has not reached its final operating temperature.
NOTE
The CALIBRATION key is only released 1 minute after having activated the UV disinfection
system. Thus, the UV C sensor can be calibrated 1 minute after having activated the UV
disinfection system at the earliest.
Calibration

Press CALIBRATION
for 2 seconds;
the displayed UV C sensor signal starts to flash

After 2 seconds, the system returns to the standard display. The alarm threshold and the safety
threshold are now newly set. The operating hours counter as well as the counter of the lamp
activations are now reset to zero.
The calibration of the UV C sensor is now complete.
