WARNING!
Insufficient treatment efficiency
Possible consequence: Death or illness.
Check minimum radiation intensity and warning
threshold.
Check and, if necessary, reset the minimum radia‐
tion intensity and warning threshold when the UV
lamp is replaced.
Only a correctly adjusted minimum radiation inten‐
sity will guarantee adequate treatment.
Controlling the UV sensor in compliance with DVGW worksheet
W294 or ÖNORM M5873-1.
Key O-w 3.0
"Lamp on" display.
1.
Remove the UV sensor at the earliest 1 minute after the UV
lamp has started.
2.
Press the OK key in order to control the UV sensor.
3.
Return to normal operating mode after controlling the UV
sensor.
After 2 minutes, the UV system switches back automatically
to the last operating mode.
ð The radiation intensity display cannot be adjusted at the
UV system. In the event of an unauthorised deviation
between the UV system UV sensor display and the refer‐
ence radiometer, the UV system UV sensor must be
replaced with a UV sensor with a valid calibration certifi‐
cate.
