HOW YOU CAN CHECK YOUR
ULTRAVIOLET SYSTEM
Your UV System is designed to prevent accidental contact
with electrical voltage and with ultraviolet rays in the sealed
unit
⎯
the ultraviolet lamp does not illuminate unless the base
is mounted on your forced air system duct.
It is recommended that every month you verify that your
ultraviolet lamp is operating.
View the bulb only through the
lamp light indicator on the lamp handle. See Fig. 11.
Do not attempt to look into the duct at the illuminated bulb(s).
