Lamp maintenance is very important because the UV-C light
emitted by the source is not visible to the eye, so, although you
see the lamp ON, its germicidal effect may not be sufficient to
perform disinfection treatment.
Before reaching the lamp,
ALWAYS
switch off at the power supply.
If the UV-C lamp gets dirty (or dusty) clean it with a clean cloth and
alcohol. Avoid touching the glass part with hands. To check UVC lamp
life (number of hours), of the spare UV lamp please refer to table
1(correct product code required). The lamp, once it has reached the
timing for replacement,
must be replaced
, this operation is carried out
as follows:
• Loosen the nuts on the lamp housing and let them slide along
the lamp; grab the lamp at the 2 ends and pull it in a direction
parallel to the lamp.
•
Repeat the steps in reverse to insert the new lamp
.

BALLAST
All UV-FLOW models are supplied with electronic ballasts which guarantees an emission of 15% more if compared
with traditional ballasts. Furthermore, lamps are not influenced by environment temperature (<-20°C). Finally, the
switching on is immediate with no starter. For this reason, lamps last longer.
To preserve the original features of original IP protection and isolation class, and to maintain all the characteristics that
guarantee the lasting of this product, the ballast replacement must be done by qualified technicians verified by Light
Progress. In case of necessity, please, send the device back to our facility for any kind of repairs.
If this is not possible you can order the entire supply channel for replacement (for code see Table 1).
