Maintenance:
Maintenance typically consists of an annual replacement of
the ultraviolet lamps.
UV lamps undergo a photochemical process during
operation. This slowly reduces the amount of UV light
generated to disinfect against airborne pathogens.
When installing new lamps, ensure that the lamp glass is
free from any fingerprints or debris, as this may alter the
path of the UV energy. Use rubbing alcohol and a dry cloth
to remove any surface contaminants.
Troubleshooting:
The Ultravation air disinfection equipment is designed to
provide many years of trouble free operation. In the unlikely
event of a problem, please contact your local dealer or
Ultravation directly. Before calling for service, you should
