Removing from Storage
As fans are removed from storage to be installed in their
final location, they should be protected and maintained
in a similar fashion until the fan equipment goes into
operation.
Prior to assembly and installation of the unit and system
components, inspect the fan assembly to make sure it is
in working order.
1. Check all fasteners, set screws on the fan, wheel,
bearings, drive, motor base and accessories for
tightness.
2. Rotate the fan wheel by hand and assure no parts
are rubbing. Access to the wheel is obtained
through a bolted panel located on the side of the
fan housing.
3. Ensure proper wheel settings for radial gap and
alignment. Refer to Radial Gap, Overlap and Wheel
Alignment section on page 8.

General Information
To ensure a successful installation, the instructions in
this manual should be read and adhered to. Failure to
comply with proper installation procedures may void the
warranty.
Unit and System Identification Tags
Each fan has a permanently affixed manufacturer's
engraved metal nameplate containing the model
number and individual serial number.
The tag shown is an example of an identification
nameplate on the fan. The information provides general
details about the fan,
as well as contains
specific information
unique to the unit.
When contacting your
local manufacturer's
representative with
future needs or questions, have the information on this
label available. Tags are mounted in an area which is
clearly visible, usually on the side of the fan cabinet.
Pre-Installation Information
Before installation, it is important to be certain the
mounting surface will bear the operating weight of the
unit. For proper unit operation, it is also important that it
be operated in a completely level position.
For further details on safety practices involving
industrial and commercial fans, please refer to AMCA
Publication 410.
Electrical Disconnects
All fan motors should have disconnects located in close
visual proximity to turn off electrical service. Service
disconnects shall be locked-out when maintenance is
being performed.
Moving Parts
All moving parts must have guards to protect personnel.
Refer to local codes for requirements as to the number,
type and design. Fully secure fan wheel before
performing any maintenance. The fan wheel may start
"free wheeling" even if all electrical power has been
disconnected. Before the initial start-up or any restart,
check the following items to make sure that they are
installed and secure.
• Do not spin fan wheel faster than the maximum
cataloged fan RPM.
• 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.
