Maintenance
Bulb Replacement
Replace all bulbs every 12 months regardless of their
condition. Refer to the manufacturer’s suggested replacement
interval.
NOTE: A glowing lamp indicates only that the UV light is
powered, not that it is emitting the necessary UVC wavelength
for germicidal effect.
Disconnect power to the unit before servicing. Verify the
power has been disconnected. Before opening the doors, use
the viewing window to make sure the UV lights are off.
