MAINTENANCE
Note: Chamber must be de-energized and included safety glasses or other UV protective
eyewear should be used at all times when performing maintenance. The chamber must be
energized when performing UV-C Dose Verication.
Check Lamp Life
It is important to monitor Lamp Life and replace when necessary. Even though the
lamps have a long default life, they will lose their power over the course of time and
need to be changed. The remaining lamp life is always prominently displayed at the top
of the Maintenance menu (see Maintenance Screen Components).

110-240V Replacement Ballast 26-0052 / 929002100325
Changing Lamps and Ballasts
To replace lamps, de-energize the chamber, then simply twist the lamp and pull out
from its housing. Slide the new lamp in and twist to lock it in place. Do not use excessive
force. It is recommended that all lamps are replaced on 1000 cycle or 3000 hour intervals,
whichever comes rst, or after a failed UV-C Dose Verication. After lamps have been
replaced, press the “Reset Lamp” button in the Maintenance menu to reset the lamp life
counter.
Replace ballasts if replacement lamps fail to provide proper intensity, or if lamps fail to
ignite. Ballasts must be installed according to country, state, and local NEC to the same
standard as shipped from the manufacturer. After de-energizing the chamber, ballasts
are accessed via the removable side panel located inside the chamber and must be
securely xed to the bottom of the chamber.
Reset Lamp Life
• From the Home screen, choose the Maintenance button (see Maintenance Screen
Components).
• Choose the RESET LAMP button.
• Lamp Life will be reset to default, unless custom values have been entered in the
Lamp Life Settings menu.
