INTRODUCTION
Congratulations on your purchase of a new 8”
Whirl vane axial fan from Pearson Industries. It
is our goal to provide you with the highest quality
air mover. The Whirl is durable and will provide
years of trouble free service when you follow the
recommendations included in this manual.
Please read this manual before operating the
unit. If you do not understand any portion of this
manual, please contact Buhin or an authorized
dealer for additional assistance and guidance
before operating the fan.
SAFETY INFORMATION
DO NOT operate the 8” Whirl fan without rst
reading this owner’s Manual and understand-
ing the fans operation.
Pearson has endeavored to design and make
the best ventilation equipment possible. How-
ever, the possibility exists that the fan can be
subjected to applications for which it was not
designed. This misuse can lead to serious in-
jury or death. Refer to current OSHA job safe-
ty and health rules and regulations pertaining
to the construction industry. Pay particular at-
tention to the rules governing Permit-Required
Conned Spaces for General Industry 29 CFR
1910.
This fan is designed and made for air ventila-
tion only. It is not designed to move/transport
any sort of liquid or semi-liquid material.
Do not operate the fan in any explosive or
ammable atmosphere. Neither the mo-
tor nor the fan is designed to work in such
environments. Serious property damage,
injury or death may result if used in an ex-
plosive or ammable environment.
Keep the unit grounded with a three pronged
grounding plug and a grounded electrical out-
let. Do not use an ungrounded extension cord
or an ungrounded adapter.
GETTING STARTED
1) Read this owner’s manual to familiarize your-
self with all warnings and precautions.
2) Inspect the fan to conrm that it’s in its original
factory conguration. If it is not, contact Buhin or
an authorized Buhin representative.
3) Always use your legs to lift the fan to help
prevent back injury.
4) The fan should not be operated by a minor.
Use caution when operating this fan around chil-
dren.
5) Inspect the fan on a regular basis for signs of
any damage and lose or worn parts. Inspect all
accessories as well.
6) Understand how to turn the fan off in an emer-
gency. Turn it off by pushing the ON/OFF switch
which is located on the side of the unit or unplug
it at the power source.
7) The fan uses a NEMA 5-15P plug and is de-
signed to work ONLY from a grounded, 115 volt
nominal AC, 60Hz, single phase power source.
This power source should utilize a NEMA 5-15R
receptacle. Use a ground fault circuit interrupter
(GFCI) to further protect against electrical shock
hazards caused by ground faults.
Always use caution before entering a con-
ned space area. Test all conned space
air with gas detection equipment that is
appropriate for the job. Assume that a
conned space is contaminated until it is
proven otherwise.
DANGER!

GENERAL SAFETY INFORMATION
1) Do not operate any fan with a damaged cord
or plug. Discard fan or return to an authorized
service facility for examination and/or repair.
2) Do not run cord under carpeting. Do not cover
cord with throw rugs, runners, or similar cover-
ings. Do not route cord under furniture or appli-
ances. Arrange cord away from trafc area and
where it will not be tripped over.
3) Do not block the air intake grill.
4) Do not put any object in the air intake grill.
5) Do not place the fan in standing water be-
cause of extreme shock hazard.
6) Do not operate the fan outside when it is rain-
ing. Only store the fan indoors.
7) Do not discharge ammable solvents or
chemicals through the fan air intake grill.
8) Do not use the Fan in areas where amma-
ble or combustible liquids, gases, vapors, dust,
bers, or lings may be present.
9) This fan is not toy.
8) A properly grounded outlet should only be
used with this fan.
9) Unplug the fan from the power supply before
servicing and when not in use.
10) Do not handle the fan with wet hands. Do not
pull or carry the fan by its cord, do not use cord
as a handle, do not close a door on the cord, and
do not pull cord around sharp edges or corners.
Keep cord away from heated surfaces. Do not
unplug the fan by pulling on cord, grasp the plug
and not the cord.
11) Do not place hair, loose clothing, ngers,
and any parts of the body near the air intake grill.
12) Do not allow water inside the motor. Un-
plug the fan and let it dry thoroughly before
using again, if the motor becomes wet.
13) Do not remove ground from the power
cord. Removing it may result in electrical
shock or electrocution. Removing the ground
will void the warranty.
14) Inspect the fan if it has been dropped, left
outdoors, or dropped into water, etc.. Thor-
oughly inspect it prior to use.
15) Do not install ducting when the fan is in
operation.
DO NOT USE THE FAN IF THE INLET AND
OUTLET GRILLS ARE NOT INSTALLED.
If the Fan is not working or if you have a
question about its safe operation, do not
operate it.

vice Center, or the factory direct at (847) 963-

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. Conrm
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
airow. 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 airow.
7) Never stand in front of the fan in the di-
rection of airow. 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 airow.
10) Keep in mind that using duct will decrease
the airow rate.
11) Always test the atmosphere for explosive
gases prior to turning on the fan. Be sure to
continually retest the atmosphere.
