Utility Fans

4

Guards – Motor Cover, Weatherhood, 
Shaft, Belt, Inlet or Outlet 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.

Access Doors

Before opening access doors, ensure the fan wheel 
has stopped moving and that the wheel has been 
secured from being able to rotate. Do not operate fan 
without access 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.

Fans – Rigging and Lifting

IMPORTANT

Fans should never be lifted by the shaft, motor, 
motor cover or accessories.

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, please 
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 effects 

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.

General Information

1.  Before lifting, be sure that all shipping materials 

have been removed from the unit.

2.  Use standard lifting and rigging practices.

3.  ALL lifting brackets on each unit must be utilized at 

the same time.

4.  Fan to be kept level during lifting and installation.

5.  Spreader bars must span the unit to prevent 

damage to the unit by the lifting cables.

6.  Always test-lift the unit to check for proper balance 

and rigging before hoisting to desired location.

7.  Never lift unit in windy conditions.

8.  Preparation of roof opening should be completed 

prior to lifting unit to the roof.

Fans are to be rigged and moved by the lifting 
brackets provided or by the skid when a forklift is 
used. Location of brackets varies by model and size. 
Handle in such a manner as to keep from scratching 
or chipping the coating. Damaged finish may reduce 
ability of fan to resist corrosion. 

See coating repair section of this manual for details 
regarding touch-up of damaged surfaces.

NOTE

Models XUEF(D)-100-BI and XUEF-100-FC will 
include an integrated electrical disconnect.
