INTRODUCTION
This manual is to be used to aid in the proper installation, operation, and maintenance of the above Carnes fans. This
information is meant to serve as a general guide. Due to the variety and complexity of many installations it is the
responsibility of the purchaser to assure that these procedures are handled by qualified personnel.
GENERAL CAUTIONS
1.
Installation of this fan requires experienced personnel with knowledge of structural strength, mechanical setup
and electrical wiring. Do not attempt installation without qualified personnel.
2.
Do not operate this fan in an environment or atmosphere where combustible or flammable materials, gasses or
fumes are present unless it has been specifically designed and manufactured for use in that environment.
MECHANICAL INSTALLATION CAUTIONS
1.
Turn the propeller by hand to check clearances. If needed, adjust the bearing or motor position to center the
propeller.
2.
On belt drive units, check that belts are aligned and tensioned properly (see Maintenance section.)
3.
Check that set screws are tight and shaft keys are in place.
ELECTRICAL INSTALLATION CAUTIONS
1.
Be sure the supply voltage matches the motor plate voltage. On dual voltage motors, check the motor wiring to
determine the voltage.
2.
Fans must be grounded.
3.
Keep all wiring clear of rotating components and moving parts such as powered or gravity dampers.
4.
Make sure power is locked
OFF
at the service entrance before wiring or otherwise approaching the fan.
5.

2.
This fan is
either
built for supply
or
exhaust application. Refer to the Model Number or dimensional drawings in this
manual if there is any question.
3.
Any optional dampers should be mounted to allow free and unobstructed operation. Allow a minimum of 8” clearance
between the fan and damper.

3.
During the first few hours of operation, periodically check the fan for smooth operation.
4.
After the first few hours of operation, shut the fan down and lock the power
OFF
. Check sheave and propeller set
