PRODUCT APPLICATION
PRINCIPLE OF OPERATION
The Sanitaire®design has been carefully conceived to provide germicidal ultraviolet exposure for air disinfec-
tion. The dosage, as it applies to ultraviolet disinfection, is a function of time, and the intensity, of ultraviolet radiation,
to which the air is exposed. The exposure time, in seconds, is the total time it takes the air to move through the ultravi-
olet field, produced by the germicidal lamp(s). Exposure time is related to the airflow rate; the higher the airflow, the
lower the exposure time or the lower the airflow, the higher the exposure time.
The operation of the Sanitaire®is as follows:
1. Air is drawn into the sanitizer through the electrostatic filter(s).
2. The air is forced into the exposure chamber, where it is irradiated by the germicidal ultraviolet lamps.
3. Sight glass provides positive indication of germicidal lamp operation.
4. The purified air exits the sanitizer, through the louvered exhaust panel, located at the opposite end of the
sanitizer. In the case of the Sanitaire®Model RSA760, once through the louvered exhaust panel, air is
forced through a .3 micron HEPA filter and finally through an electrostatic particulate filter before exiting
the sanitizer.

CONSTRUCTION
The Sanitaire®Room Air Sanitizers consists of:
• Germicidal ultraviolet lamps, which deliver ultraviolet energy in the specific wavelength of 254 nanometers (nm),
which is highly effective against airborne microbes including: virus, bacteria, and mold spores.
• 120-volt 60Hz electronic ballast(s).
• A polished reflector, whose design and specular aluminum construction, maximizes ultraviolet intensity within the
exposure chamber.
• A standard, NEMA 5-15, three-prong plug, and operates on 120VAC 60Hz single-phase standard household
current. The Sanitaire®is also available for operation on 230VAC 50Hz.
• Permanent, washable, electrostatic intake filter(s), capable of removing airborne particles as small as 5 microns.
• A louvered exhaust, which restricts ultraviolet radiation from passing into the room, protecting the room's
occupants from ultraviolet exposure.
• A sight glass assembly, which provides visual indication of germicidal lamp operation without the risk of
ultraviolet exposure.
• An enclosure and access cover constructed of stainless steel, type 304. Stainless steel construction provides
strength, durability and lasting value.
• An interlock safety switch. The interlock switch interrupts power to the sanitizer, when the access cover is
removed from the lamp/exposure chamber.
• Molded rubber feet, for use on tabletops, shelves, etc. and standard wall mounting brackets (Models RS72, RS140
and RS435 only). These brackets allow the Sanitaire®to be mounted to a wall, or other vertical surface, in
either the vertical or horizontal position. Optional mounting kits are available; consult our application specialists
for specific details.
• A .3-micron, 99.97% minimum efficiency, HEPA type, absolute filter (Model RSA760 only).
LIMITATIONS
Overexposure to germicidal ultraviolet rays will result in the irritation of the eyes and reddening of the skin. For that
reason, it is of the utmost importance that your ultraviolet application be carefully planned and implemented so as to
avoid exposure, of personnel, to direct or reflected ultraviolet rays.
The American Conference of Governmental Industrial Hygienists (ACGIH) has established that the ultraviolet
radiant exposure incident for unprotected eyes or skin should not exceed 0.2 microwatts per square centimeter
(µW/cm2) at 254 nanometers (nm) for an eight (8) hour period. ("2004 TLVs®and BEIs®")

INSTALLATION
UNIT PLACEMENT
For maximum efficiency the Sanitaire®should be located as centrally as possible, preferably not close to the floor or
the corners of the area to be treated.
Access to the room does not need to be controlled while the sanitizer is operating. The louvered exhaust panel, of the
Sanitaire®Room Air Sanitizer, restricts ultraviolet radiation from passing into the room, protecting the room's occu-
pants from ultraviolet exposure.
To ensure safe and proper use, make sure the area:
• Has a properly grounded, electrical outlet within 6-feet of the unit.
• Has a plumb, secure wall, for standard wall mounting.
UNPACKING
Remove the Sanitaire®Room Air Sanitizer from its shipping carton. Atlantic Ultraviolet Corporation takes all possible
precautions when packaging this unit to prevent damage. Carefully inspect the sanitizer, power cord and plug for damage,
report all damage immediately. Do not assemble or operate if there is any damage, visible or suspected.
Germicidal lamps are packed separately, to ensure maximum protection for the lamps. Keep the lamps aside until ready for
installation. When installing lamps into the sanitizer, avoid touching glass with bare hands. Oils deposited, from fingers, on
the glass could effect ultraviolet transmission.
Carefully inspect all packing materials to prevent the loss of accessories, mounting hardware, spare parts or instructions.
Do not discard packing materials until sanitizer is assembled and check out is complete.

MAINTENANCE
• The Sanitaire®is designed to operate with a minimal amount of maintenance. Besides occasional ultraviolet
measurements to insure that ultraviolet intensity in the treated areas remain within the allowable exposure limits,
a regular cleaning cycle of the germicidal lamps, interior reflector, sight glass and intake filter(s) should be
established, and carefully maintained, based on visual inspection and experience. The frequency of cleaning will
vary with the conditions surrounding each installation. It is recommend that the germicidal lamps, interior reflector,
sight glass and intake filter(s) be cleaned whenever dust deposits are observed.
• 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 recom-
mended every one year of continuous operation.
• Unless lamp replacement is due to failure or breakage, it is recommended that all lamps be replaced at the same time.
REQUIRED SUPPLIES
• Vacuum cleaner
• Detergent
• Water
• Soft, clean, lint-free cloth
• Alcohol, or suitable glass cleaner
CAUTION: Do not override the safety interlock switch. Operation of the sanitizer with the interlock
switch disabled and the access cover removed will expose personnel to direct and/or strongly reflected germicid-
al ultraviolet rays. Germicidal ultraviolet rays are harmful to the eyes and skin.
WARNING: Always disconnect power, to the sanitizer and unplug, before performing any service or
maintenance.
