UV Light Hazard.
Harmful to bare skin and eyes.

Never look at the lamps while illuminated.
Only view illumination by way of the light indicator located on the lamp knob.
To prevent exposure to ultraviolet light, disconnect power to the ultraviolet air
treatment system before servicing any part of the heating/air conditioning
system.
Do not mount device in location that allows ultraviolet light to be seen after
installation.

Do not attempt to open housing; unit is sealed to prevent ultraviolet light
exposure.
Your Ultraviolet Air Treatment System has a power cord that plugs into a 120 Vac
electrical outlet. Your unit is designed to prevent accidental contact with the voltage
and with the ultraviolet rays in the sealed unit  the ultraviolet lamps do not illuminate
unless the base is mounted on the HVAC duct.
It is recommended that every month you verify that your ultraviolet lamp(s) are
operating only by viewing through the lamp light indicator on the lamp knob. Do not
attempt to look into the duct at the illuminated lamp(s).
