MAINTENANCE
Always disconnect power to the fixture before performing any service or maintenance
.
• The
SANITAIRE
®
is designed to operate with a minimal amount of maintenance.
• A regular cleaning cycle of the
STER-L-RAY
®
Germicidal Lamps, interior, and intake filter(s)
MUST
be established,
and carefully maintained, based on inspection and experience. The frequency of cleaning will vary with the conditions
surrounding each use. It is recommended that the ultraviolet lamps be cleaned at least once every three (3) months.
• The
STER-L-RAY
®
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.
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.
