MAINTENANCE / UV LAMP INDICATOR
DISPOSAL OF THE PCO CELL
Your Duct Pure 80K unit requires no periodic
maintenance beyond normal replacement of the
PCO cell every 3 years .
Note: For optimal performance, we recommend the
replacement of the PCO cell every 3 years, especially
if the UV lamp appears to be operating normally .
The UV lamp operation indicator on the face of
the unit will glow when the UV lamp is in use . If the
indicator does not glow and the unit has power, the
PCO cell should be replaced .
Please do not throw a used PCO Cell in the garbage .
The special germicidal UVX bulb used in the Duct
Pure 80K contains a very small amount of mercury .
Contact your local Waste Management Center for
a proper disposal procedure .
