The
SANITAIRE
®
design has been carefully conceived to provide germicidal ultraviolet exposure for air disinfection. 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 ultraviolet field, produced by the
germicidal lamps. 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
®
Germicidal Ultraviolet Room Air Sanitizer is as follows:
1.
Air from the room is drawn into the fixture through the four intake grills in the lower half of the unit’s body and pulled thru
the pleated filters behind each of these grills.
2. The air is forced upwards into the exposure chamber, where it is irradiated by the eight germicidal ultraviolet lamps.
3. The treated air exits the top of the unit, through the louvered- exhaust panel and reintroduced to the room.

It is the user’s responsibility to determine and validate the suitability of the equipment for use in system
or process. No warranty or representation is made by the manufacturer with respect to suitability or performance of this
equipment or to the results that may be expected from its use.
Indoor Use Only – The equipment must be sheltered from exposure to the elements and extremes in
temperature. Temperature range: 40°F to 95°F. The user should periodically inspect, clean as necessary and confirm the
presence and good legibility of the Product safety labels. Contact the factory for replacement labels in the event that any of
the labeling is missing or illegible.
The UV Treatment Results achieved are subject to variations in application conditions, it is recommended
that culture tests be performed to confirm desired outcomes.

• 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 people and other living things
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. (
