MAINTENANCE
DANGER!
Shut off the fan and unplug it before conduct-
ing any service or inspection . Accidental elec-
trocution or shock may occur if the fan is not
disconnected from a power supply. Confirm
that the fan blade has stopped rotating before
removing the grills and handling the fan blade.
1) Check for any loose or broken fasteners
or components. Replace, repair or tighten as
needed with only factory approved parts.
2) Clean the fan blade of any debris. A build
up of debris such as paint, cement dust, dirt,
etc can unbalance the fan blade and damage
the unit.
OPERATION
1) When unpacking the fan, inspect it for any
damage that may have occurred during ship-
ping.
2) Read this manual before connecting and
operating the fan.
3) Determine if your job is considered hazard-
ous. The working environment may contain
explosive gases or dust in explosive amounts.
4) The outlet to be used must be grounded.
5) Make sure that both grills on the fan are
not obstructed in anyway that may restrict the
airflow. Do not operate the fan at anytime if
the grills are not installed.
6) The fan is marked with an arrow on either
side. This is the direction of airflow.
7) Never stand in front of the fan in the di-
rection of airflow. Serious injury or death may
occur from being struck with debris that are
sucked into the fan and discharged at a high
speed.
8) Install duct when the fan is turned off and
unplugged.
9) Do not place the fan next to an obstruction
such as a wall as this will decrease airflow.
10) Keep in mind that using duct will decrease
the airflow rate.
11) Always test the atmosphere for explosive
gases prior to turning on the fan. Be sure to
continually retest the atmosphere.
