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 containing
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 housing.
Pre-Installation Information
Before installation, it is important to be certain the
mounting surface will bear the operating weight of the
fan. For proper fan 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
propeller before performing any maintenance. The fan
propeller 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 propeller 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.

Tube Axial Upblast Fans
Guards – Motor Cover or Inlet Guard
Do not operate fans without proper protective devices
in place. Failure to do so may result in serious bodily
injury and property damage. Check local codes to
ensure compliance for all protective devices.
Inspection Door
Before opening the inspection door, ensure the fan
propeller has stopped moving and that the propeller
has been secured from being able to rotate. Do not
operate fan without inspection door in its fully closed
position.
Air Pressure and Suction
In addition to the usual hazards associated with
rotating machinery, fans also create a dangerous
suction at the inlet. Special caution needs to be used
when moving around a fan, whether it is in operation
or not. Before start-up, make sure the inlet area is
clear of personnel and loose objects.
