WARNING!
Insufficient treatment efficiency
Possible consequence: Death or illness
Check safety and warning threshold.
Check and possibly reset the safety and warning
threshold when the UV lamp is replaced.
Only a correctly adjusted safety threshold will guar‐
antee adequate treatment.
Calibration of the UV sensor
Calibrate the UV sensor once the UV system has
been switched on.
9.5 Calibration of the UV sensor
NOTICE!
Only a correctly calibrated UV sensor guarantees
adequate water treatment.
Ensure that water to be disinfected is flowing
through the radiation chamber when calibrating the
UV sensor.
Always calibrate the UV sensor with new UV
lamps.
Operate the UV lamps at maximum power when
calibrating the UV sensor.
The safety threshold and warning threshold are no longer moni‐
tored when calibrating the UV sensor.
