10.3 Maintenance
Changing the xenon lamp:
To keep constant radiation, it is necessary to change the
xenon lamp at intervals of 1,500 hours (see section 6.3).
The recommended change after 1,500 operating hours
is indicated on the program control panel. The age of the
xenon lamp can also be reviewed during the program run
(see software documentation manual).
Cleaning the water filter:
The water pump filter must be cleaned every six months.
In case of heavy debris caused by particles removed
from samples during testing, the filter must be changed
immediately. The filter should be replaced with a new filter
after cleaning it twice.
