UV Filter
CAUTION
Oily fingerprints on the lamp or quartz tube will cause the lamp or quartz tube to
fail prematurely. Wear gloves or wipe down these parts with alcohol before
installing them in the system.
The UV filter lamp and quartz jacket should be replaced every 9,000 hours of operation
(annually); an hour meter on the power panel keeps a cumulative time of operation. The UV lamp
may continue to operate after 9000 hours of use, but the wavelength of the light produced will no
longer provide an adequate kill rate. The lamp is accessed from the left access door of the unit. To
replace the lamp, shut down the unit by pressing the SmartPad™ Standby key , disconnect
power from the unit, pull out the lamp using the harness cap as a handle until the lamp is
extended far enough to unplug the harness, and withdraw the lamp from the unit.
