The UVC lamp is a wear part. Replace the UVC lamp once the indicated number of operating
hours has been reached. This ensures optimum filtering performance.
Prerequisite:
The UVC unit head has been removed. (→ Removing the UVC unit head)
Only use UVC lamps, the identification and power data of which correspond to the information
on the type plate. (→ Technical data)
How to proceed:
Removal: Turn the bayonet ring all the way to the “lock open” position to remove the holding
plate and the UVC lamp.
Installation: Turn the bayonet ring all the way to the “lock closed” position. Otherwise you
cannot install the UVC unit head.
– On delivery, the bulb of the UVC lamp is protected by a transport guard. The lamp guard is
not required for the lamp function and does not need to be reinstalled.
If necessary remove a lamp guard stuck in the quartz glass as follows:

Carefully and steadily knock the rotor lid with the quartz glass against a firm surface. The
lamp guard will slowly slide out of the quartz glass.
OSRAM UVC lamps can only be installed without the holding plate. OASE therefore recom-
mends using Philips UVC lamps.
