 Fume Exhaust Fans

Guards – Motor Cover, Weatherhood

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.

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 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.
