Typical maintenance consists of 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. For
optimum air stream disinfection against airborne pathogens it is recommended the UV lamps be changed on an annual basis.
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.
