MAINTENANCE
• The Sanitaire®Model RSCS280 is designed to operate with a minimal amount of maintenance.
• A regular cleaning cycle of the germicidal lamps, interior, and intake filter should be established, and carefully
maintained, based on inspection and experience. The frequency of cleaning will vary with the conditions
surrounding each installation. It is recommended that the ultraviolet lamps be cleaned at least once every three
(3) months.
• The germicidal ultraviolet lamps used in the Sanitaire®have a manufacturer's rated average effective life of
10,000 hours. Lamps may operate longer than their rated effective life, but the reduction in ultraviolet output will
make it impractical to use past the manufacturer's rated life. For maximum efficiency lamp replacement is
recommended every 10,000 hours of operation or about one (1) year of continuous use.
• Unless lamp replacement is due to failure or breakage, it is recommended that all lamps be replaced at the same time.
• The Sanitaire®Model RSCS280 is equipped with a safety interlock switch, which will shut down the germicidal
lamps when the Access Door is opened.
CAUTION: Do not override the safety interlock switch. Operation of the fixture with the interlock
switch overridden and the Access Door open will expose personnel to direct or strongly reflected germicidal
ultraviolet rays. Germicidal ultraviolet rays are harmful to the eyes and skin.
WARNING:Always disconnect power to the fixture before performing any service or maintenance.
