shock hazards caused by ground faults in commercial, industrial and residential
applications. Electrically driven blowers are designed to operate ONLY from a grounded
115 volt AC, 60Hz or 220V/60Hz (select models w/220V/50Hz), single phase power
source. All electrical wiring installations and connections must comply with all applicable
NEC statutes and with all applicable local codes and practices. (For specific information,
consult the NEC publications and OSHA publications 210-22D for construction sites and
555-3 for marina’s or for use around any area containing water.)
DO know where the controls are, how they operate, and how to stop the blower in an
emergency.
DO place the blower on secure footing to prevent it from shifting while in use. Such
movement can cause injury to the operator(s) or damage to the blower itself.
DO ensure blower is operated in a horizontal position to meet the enclosure definition.
The blower is designed for operation in job site areas that are reasonably dry, clean and
provide for a continuous, dynamic source of air for cooling the motor. Any questions
about operating environments, contact the Allegro Technical Support at 1-800-622-
3530, or e-mail at [e-mail], before using the blower.
WARNINGS AND LIMITATIONS
Flow rate testing performed by the Colorado Engineering Experiment Station, Inc. and
Allegro Industries. The Blowers were tested per AT&T Standard EL2723/PL2709 in a
chamber built in accordance with AMICA Standard 210-67. Tests performed with a
single, 8 inch (203mm) diameter x 15 feet (7.6m) flexible, reinforced duct connected to
the blower outlet (with the exception of Free Air results). The published flow rates are
intended to serve only as a reference.
Manufacturing tolerances and specific operating parameters will affect the overall flow
rate(s) for each particular blower. Actual flow rate will decrease when the total length of
the ducting is increased more than 15 feet (7.6m). Actual flow rates may change if
blower is used with ducts manufactured and/or supplied by other sources.
CAUTION!
The final working procedure for any job application involving the use of the blower
must be individually determined after careful analysis of all factors and/or conditions
present. The nearest OSHA office is a valuable source for applicable information
regarding the operation of the blower.
