3. Installation
3.1. BEFORE YOU BEGIN
Important:
All fan installation and maintenance must be done by a qualified electrician in
accordance with all applicable local codes and standards.
3.2. LOCATION & MOUNTING
Flat Bottom Bins:
• Fan must be mounted and attached to a flat, level concrete surface.
• Ensure fan fits properly with the bin transition ducting.
• Fan must be mounted as close to the bin as possible. Leave 12” to 18” or
more between the fan and bin to allow for routine servicing and inspec-
tion.
• Provide adequate drainage to protect the fan.
Hopper Bottom Bins:
• Fan must be properly mounted on a platform or braced in a similar man-
ner to support the fan’s weight.
3.3. ELECTRIC MOTOR WIRING
• Voltage, amperage, and rpm’s are located on the specification plate on the
fan housing.
• A wiring diagram is located on the inside of the fan electrical box lid.
• Use a separate circuit from the distribution panel for the fan.
• Installing a time-delayed circuit breaker will allow for start up current (mini-
mum requirement is 2.5 times the maximum running amperage on motor
nameplate). Check with local electrical code for more details.
• Ensure proper gauge of cable between power source and fan unit. See Table
3.1.
Warning:
Before continuing, ensure you have read and understand the relevant information
in the safety section. Safety information is provided to help prevent serious injury, death, or
property damage.
NOTICE
Damage will occur to the fan if not properly supported.
NOTICE
Incorrect gauge of cable will result in low voltage supply to
the motor causing premature failure.
