Square Mixed Flow Inline Fans
Fans are direct-driven with mixed flow wheels and feature ridged construction,
high-efficiency and low sound levels. These compact inline fans are the ideal
selection for indoor clean air applications including intake, exhaust, return, or
make-up air systems. The square housing design, compact size, and straight-
thru airflow also provide the system designer the flexibility to mount in horizontal
and vertical orientations. Each fan displays a permanently stamped metal
nameplate with complete model number, mark, and unique serial number for
future identification.
General Safety Information
Only qualified personnel should install this fan.
Personnel should have a clear understanding of these
instructions and should be aware of general safety
precautions. Improper installation can result in electric
shock, possible injury due to coming in contact with
moving parts, as well as other potential hazards. Other
considerations may be required if seismic activity
is present. If more information is needed, contact a
licensed professional engineer before moving forward.
1. Follow all local electrical and safety codes, as well as
the National Electrical Code (NEC) and the National
Fire Protection Agency (NFPA), where applicable.
Follow the Canadian Electric Code (CEC) in Canada.
2. The rotation of the wheel is critical. It must be free
to rotate without striking or rubbing any stationary
objects.
3. Motor must be securely and adequately grounded.
4. Do not spin fan wheel faster than max cataloged fan
RPM or this could cause catastrophic wheel failure.
Adjustments to fan speed significantly affects motor
load. If the fan RPM is changed, the motor current
should be checked to make sure it is not exceeding
the motor nameplate amps.
5. Do not allow the power cable to kink or come in
contact with oil, grease, hot surfaces or chemicals.
Replace cord immediately if damaged.
6. Verify that the power source is compatible with the
equipment.
7. Never open access doors to a duct while the fan is
running.
8. Never remove covers protecting electrical
components while fan is energized.
