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.
5. 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.
6. Make certain that the power source conforms to the
requirements for the equipment.
7. Never open access door to a duct with the ventilator
running.
8. 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. Rotate propeller by
hand to be sure it turns freely.
Do not raise ventilator by its windband; use a sling or platform.
Installation
Installation, troubleshooting and parts replacement is to be performed
only by a qualified personnel. Consult and follow NFPA 96
recommendations. NFPA 96 instructions supercede this document.
NOTE: Refer to motor nameplate for wiring procedures. Refer to switch
manufacturer for installation and wiring procedures.
1. Cut an appropriate sized hole in the roof surface. Follow curb
manufacturer's installation instructions. Caulk and flash curb to ensure
a water tight seal.
2. Install optional backdraft damper. Secure damper flange to curb
damper tray, with fasteners provided.
3. Remove motor cover.
4. Place ventilator on curb.
5. Secure ventilator to roof curb using a minimum of eight fasteners.
6. Check ventilator

9. Replace motor cover.
10. Wire control
switches at ground
level.
Operation
1. Before starting up or operating, check all fasteners for tightness. In
particular, check set screws in propeller hub. While in the OFF
position, or before connecting the ventilator to power, turn the fan
propeller by hand to be sure it is not striking the venturi or any
obstacle.
2. Start the ventilator up and shut it off immediately to check rotation of
the propeller with directional arrow in the motor compartment.
Ventilator propeller should rotate clockwise when viewed from the top.
3. When the ventilator is started, observe the operation and check for
any unusual noises.
4. With the system in full operation and all duct work attached, measure
current input to the motor and compare with the nameplate rating to
determine if the motor is operating under safe load conditions.
5. Keep inlets and approaches to ventilator clean and free from
obstruction.
