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 aluminum 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 sales representative with future needs or
questions, please have the information on this label
available. Tags are mounted in an area which is clearly
visible.
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
Fan is provided with an integrated service disconnect.
Service disconnects shall be locked-out when
maintenance is being performed.
Clearances
For best airflow and throw distance, proper inlet and discharge clearances should be maintained.
Blocking the fan's inlet or discharge; mounting the fan close to an obstruction or wall will inhibit proper airflow into
the fan, thereby reducing its effectiveness or causing performance issues.

Moving Parts
All moving parts must have guards to protect personnel.
Refer to local codes for requirements as to the
number, type and design. 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.
Guards
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.
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.
