Fan Installation
Electrical installation, service,
or maintenance work must
be performed by a qualified electrician and
comply with all applicable national and local
codes.
Turn power off and lock out all power before
performing service or maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Mounting a fan blower on the side of a
collector requires a side power adapter to
support the weight of the fan blower.
Poorly installed fan blowers may separate from
the collector resulting in personal injury and/or
property damage.
When mounting fan in an outdoor
or high humidity environment,
mount the motor with drain holes facing down
to extend motor life.

TBI fans are dynamically balanced and tested at
operating speeds to check for conformance to vibration
limits. All fans must be adequately supported for smooth
operation.
Safe operating spped is a function of system temperature
and wheel design. TBI fans should not be operated
above 3,600 RPM.
Do not allow the fan wheel to
come loose from the motor as it
may cause severe injury or property damage.
To ensure proper attachment of the fan wheel:
Tighten all setscrews in fan wheel.
Repeat after 8 hours of operation.
Repeat again after two weeks of operation.
Reference Torque Value Table.
For additional information, contact the motor
manufacturer.
Set screws should never be used more than once. If the
set screws are loose, they must be replaced. Use only
knurled, cup-point screws with a nylon locking patch.
