2.1. Safety Alert Symbol and Signal Words
This safety alert symbol indicates important safety messages in this manual. When you see
this symbol, be alert to the possibility of injury or death, carefully read the message that
follows, and inform others.
Signal Words: Note the use of the signal words DANGER,WARNING,CAUTION, and NOTICE with the safety
messages. The appropriate signal word for each message has been selected using the definitions below as a
guideline.
Indicates an imminently hazardous situation that, if not avoided, will result in serious injury or
death.
Indicates a hazardous situation that, if not avoided, could result in serious injury or death.
Indicates a hazardous situation that, if not avoided, may result in minor or moderate injury.
Indicates a potentially hazardous situation that, if not avoided, may result in property damage.
2.2. General Product Safety
YOU are responsible for the SAFE use and maintenance of your centrifugal fan. YOU must ensure that you and
anyone else who is going to work around the centrifugal fan understands all procedures and related SAFETY
information contained in this manual.
Remember, YOU are the key to safety. Good safety practices not only protect you, but also the people around
you. Make these practices a working part of your safety program. All accidents can be avoided.
• It is the centrifugal fan owner, operator, and maintenance personnel's responsibility
to read and understand ALL safety instructions, safety decals, and manuals and
follow them when assembling, operating, or maintaining the equipment.
• Owners must give instructions and review the information initially and annually with all personnel before
allowing them to operate the centrifugal fan. Untrained users/operators expose themselves and bystanders
to possible serious injury or death.
• The centrifugal fan is not intended to be used by children.
• Use the centrifugal fan for its intended purposes only.
• Do not modify the centrifugal fan in any way without written permission from the manufacturer.
Unauthorized modification may impair the function and/or safety, and could affect the life of the centrifugal
fan. Any unauthorized modification of the centrifugal fan will void the warranty.

2.3. Fan Safety
• Keep away from fan impeller/blade; high suction can pull a
person toward the inlet. Contact with an unguarded
impeller/blade will cause severe injury.
• Keep the inlet screen in place at all times.
• Remove foreign material from the fan inlet before operating.
• Do not operate the fan if there is excessive vibration or noise.
• When the power is locked out, fans can still be dangerous
because of potential “windmilling.” Always block the
impeller/blade before working on any moving parts.
2.4. Guards Safety
• Keep guards in place. Do not operate with guard removed.
• Do not walk on, step on, or damage guards.
• Lock out power before removing a guard.
• Ensure all guards are replaced after performing maintenance.
2.5. Lockout/Tagout Safety
Lockout/Tagout equipment before set-up, service, maintenance, and repair. Make sure to follow lockout and
tagout procedure in the Electric Motor Safety Section to prevent inadvertent start-up and hazardous energy
release.

overload and under-voltage protection.
• Motor starting controls must be located so that the operator
has full view of the entire operation.
• Locate main power disconnect switch within reach from
ground level to permit ready access in case of an emergency.
• Motor must be grounded.
• Guards must be in place and secure at all times.
• Ensure electrical wiring and cords remain in good condition;
replace if necessary.
SERVICE DISCONNECT

know how to use it.
2.9. Safety Decals
• Keep safety decals clean and legible at all times.
• Replace safety decals that are missing or have become illegible. See decal location figures that follow.
• Replaced parts must display the same decal(s) as the original part.
• Replacement safety decals are available free of charge from your distributor, dealer, or factory as applicable.
2.9.1 Decal Installation/Replacement
1. Decal area must be clean and dry, with a temperature above 50°F (10°C).
2. Decide on the exact position before you remove the backing paper.
3. Align the decal over the specified area and carefully press the small portion with the exposed sticky backing
in place.
4. Slowly peel back the remaining paper and carefully smooth the remaining portion of the decal in place.
5. Small air pockets can be pierced with a pin and smoothed out using the sign backing paper.
2.9.2 Safety Decal Locations and Details
Replicas of the safety decals that are attached to the centrifugal fan and their messages are shown in the figure
(s) that follow. Safe operation and use of the centrifugal fan requires that you familiarize yourself with the

3. Installation
Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.
3.1. Installation Safety
• Do not take chances with safety. The components can be large, heavy, and hard to handle.
Always use the proper tools, rated lifting equipment, and lifting points for the job.
• Always have two or more people installing the centrifugal fan.
• Make sure you have sufficient lighting for the work area.
• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,
nuts, or other hardware that is of lesser quality than the hardware supplied by the
manufacturer.
3.2. Check Shipment
Inspect the centrifugal fan and accessories on receipt to ensure that all items have arrived and that none are
damaged.
A few basic items to check:
• Ensure no loose items or debris that can be drawn into the fan or dislodged by the fan discharge. Check the
interior of the fan as well.
• Turn the fan impeller/blade by hand to check for binding.
• Check the tightness of all nuts and bolts.
• Verify that the supply voltage is correct.
Report missing or damaged parts immediately to ensure that proper credit is received from Keho or your
distributor/dealer, and to ensure that any missing parts can be shipped quickly to avoid holding up the
installation.
Important
Do not use damaged components.
3.3. Handling the Fan
Lift the fan by the base, mounting supports, or lifting locations. Never lift a fan by the wheel, motor, motor
bracket, housing inlet, outlet, or any fan part not designed for lifting. A spreader should always be used to avoid
damage.
3.4. Storing the Fan Before Installing
Check the fan wheel for free operation and lubricate moving parts prior to storage if the fan is not to be placed
immediately into service. Inspect the stored unit periodically.
3. INSTALLATION AERATION FAN – SUPER-FLOW FULL CENTRIFUGAL FAN

CNA-3733 R2 19
3.5. Installing with a Supplemental Heater
Any type of supplemental heater intended for use with this fan must be installed downstream of this fan and
may be added if extra conditioning or drying is required.
Heating incoming air will damage the fan and its components and is not covered by the
warranty.
3.6. Transition Connection Requirements
When connecting the transition, ensure the fan fits properly with the grain bin transition intended for use by
the manufacturer.
3.7. Mounting the Fan on a Flat Bottom Bin
The centrifugal fan must be properly supported for smooth operation.
3.7.1 Slab Mounted Fans
A concrete foundation is preferable for installing floor-mounted fans.
When installing the fan on a concrete pad the following general requirements apply:
• The concrete surface must be flat and level.
• The weight of the slab should be two to four times the weight of the rotating assembly, including the motor.
• The foundation requires firmly anchored fasteners such as the anchor bolts shown below. Hammer-drilled
expansion fasteners can be used in less demanding applications.
• The overall dimensions of the concrete base should extend at least six inches beyond the base of the fan.
• Locate the fan as close to the bin as possible, leaving approximately 12” to 18” or more between the fan
and bin to allow for routine servicing and inspection.
• Ensure moisture is not accumulating around the fan.
• Move the fan to the mounting location and lower it over the anchor bolts, leveling the fan with shims
around the bolts. Fasten the fan securely.
• When grout is used: Shim the fan at least 3/4-inch from the concrete base.
