General Safety Information
When Installing or Servicing the Fan
Do not depend on any switch as the sole means of
disconnecting power when installing or servicing the
fan. Always disconnect, lock and tag power source
before installing or servicing. Failure to disconnect
power source can result in fire, shock, or serious
injury. Motor will restart without warning after thermal
protector trips. Do not touch operating motor, it may be
hot enough to cause injury.
Do not place any body parts or objects in fan, motor
openings, or drives while motor is connected to
power source.
Do not use this equipment in explosive atmospheres!
1. Read and follow all instructions and cautionary
markings. Make sure electrical power source conforms
to requirements of equipment and local codes.
2. Ventilators should be assembled, installed and serviced
by a qualified technician. Have all electrical work
performed by a qualified electrician.
3. Follow all local electrical and safety codes in the United
States and Canada, as well as the National Electrical
Code (NEC), the Occupational Safety and Health Act
(OSHA), and the National Fire Protection Association
(NFPA) Bulletin 96 in the United States. Ground motor in
accordance with NEC Article 250 (grounding). Follow the
Canadian Electric Code
(CEC) in Canada.
4. Motor and fan must be securely grounded (bare metal)
to a suitable electric ground, such as a grounded water
pipe or ground wire system.
In United States, to reduce the risk of injury to persons,
OSHA complying guards are required when fan is
installed within 7 feet of floor or working level.
In Canada, to reduce the risk of injury to persons, CSA
complying guards are required when fan is installed
below 2.5 meters (8.2 feet) above floor or grade level.
1. Do not kink power cable or allow it to come in contact
with sharp objects, oil, grease, hot surfaces or
chemicals. Replace damaged cords immediately.
2. Make certain that the power source conforms to the
requirements for the equipment.
3. Never open access door to a duct with the ventilator
running.
4. Motor must be securely and adequately grounded. This
can be accomplished by wiring with a grounded, metal-
clad race way system by using a separate ground wire
connected to the bare metal of the motor frame, or
other suitable means.
Pre Starting Checks
1. Inspect for any damage that may have occurred during
transit.
2. Shipping damage claim must be filed with carrier.
3. Check all bolts, screws, set-screws, etc. for looseness that
may have occurred during transit. Retighten as required.
