3. Installation Instructions
Fan Pad Location
Fan pad should be poured level with top of bin foundation for all Inline Fans 18" through 28" diameter. Fan
should be centered on center line of bin. Front of pad should be perpendicular to bin wall. Recommended
thickness for fan pad is 4" minimum.
IMPORTANT: Fan pad and fan must be level and smooth for proper operation. Vibration problems can
result from improper fan leveling.
Figure 3A Fan Pad Installation Guidelines
Check List before Installing the Fan
1. One of the most important factors for installation is providing adequate power to run the unit.
Undersized wire can lead to voltage drop and can cause motor overheating and shortened life.
Therefore, it is necessary to know the distance from the unit to available transformer and the
horsepower of the fan unit. These two (2) factors will determine the size of wire needed for efficient
operation. See fan specifications on Page 15.
2. It is recommended to contact the local power company and having a representative survey the
installation so the wiring is compatible with their system and adequate power is supplied to
the unit.
3. Each fan motor should be wired through a fused or circuit breaker disconnect switch.
4. Refer to fan specifications on Page 15 for the recommended slow blow fuse or breaker size to use
when installing the particular fan.
5. Standard electrical safety practices and codes should be used. (Refer to National Electrical Code
Standard Handbook by National Fire Protection Association.)
6. A qualified electrician should make all electrical wiring installations.

Installation
1. Be sure that the disconnect and the fan are well grounded. See machine to earth ground on Page 17 .
IMPORTANT: All fans with controls use 120 volt control circuit. Neutral must be supplied on
230 volt 1 and 3 Phase models for unit to operate.
2. Rotate the fan blade to be sure that it revolves easily and does not rub the housing.
3. Check all fasteners on motor mounts, fan blades and other bolted items to make sure they are tight.
If any are loose, check for proper clearance and re-tighten fasteners. They may have loosened
in shipping.
4. Fans should be mounted to set level and solid. It may be necessary to shim one or more corners of
the foot mount to achieve a solid mounting. Fans not solidly mounted and properly shimmed may
have excess vibration in them.
5. Check and re-tighten all electrical connections. They may have loosened in shipping.
Always disconnect and lock out power before working on or around fan.

5. Fan Installation
Figure 5A
Previously Installed Units
It is recommended that previously installed units be checked to see that a machine to earth ground has
been installed by an electrician.
Machine to Earth Ground
It is very important that a machine to earth ground rod be installed at the fan. This is true even if there is
a ground at the pole 15 feet (15') away. This ground needs to be as close to the fan as possible, but no
more than 8 feet (8') away. The ground rod should be connected to the fan control panel with at least a #6
solid bare copper ground wire or in accordance with local requirements. The machine to earth ground
provides additional safety if there is a short. It also provides the grounding necessary for long life and
operation of the solid state.

Use a #6 or approved size bare copper ground wire. Install a 5/8" diameter 8' long
copper-clad ground rod, 2' away from the foundation and 1' below the surface of the
ground or in accordance with local requirements.

5. Fan Installation
18 PNEG-119 Inline Centrifugal Fan
Proper Installation of the Ground Rod
(Ground rods and wires are not supplied by GSI.) It is recommended that the rod not be driven into dry
ground. The following steps ensure proper ground rod installation:
1. Dig a hole large enough to hold 1 to 2 gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing the rod up and down, the water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installing the rod gives a good conductive
bond with the surrounding soil.
5. Connect the bare copper ground wire to the rod with the proper ground rod clamp.
6.Connectthebaregroundwire tothefancontrolboxeswitha groundinglug. (See Figure 5A
on Page 17.)
7. Ground wire must not have any breaks or splices. Insulated wire is not recommended for grounding.
Figure 5B
Dig a hole large enough to hold 1 or 2 gallons
of water. Work the ground rod into the earth
until it is completely in the ground.

PNEG-119 Inline Centrifugal Fan 19
6. Fan Operation
Start-Up
On initial start-up of the fan, run it momentarily to make sure that the fan blade is rotating in the proper
direction and airflow is correct. If not, change motor direction using instructions on the motor.
Proper installation and start-up ensures many years of trouble-free operation.
Maintaining Grain Quality
To properly maintain the quality of stored grain, it is necessary to keep the grain dry, cool and insect free.
Any one of these problems can contribute to spoilage. Wet, warm grain promotes insect growth as well as
grain spoilage. Cool, dry grain can keep for long periods of time.
It is recommended that the grain be kept cool (avoid freezing as freezing can reduce quality). Grain should
be cooled through the fall and winter, warmed in the spring and summer.
Grain Storage
Average grain temperature should be above 35°F in the winter and below 65°F in the summer. Always try
to keep the grain within 10°F-15°F of the average monthly outside temperature. This means grain may
need to be aerated on warm days during the winter to stay above 35°F when freezing temperatures
are predominate.
During the summer it may be necessary to aerate the grain on cool nights, so the 65°F temperature is not
exceeded during the hot days of summer.
Conditions and requirements may vary from area to area. We suggest that you contact the local
Agriculture Extension Office or State Agriculture University for more exact guidelines.
If the grain is to be stored more than 1 year, it has to be recooled the following fall and winter, repeating
the process as long as the grain is in storage. Frequent and regular inspection (at least weekly during
fall and spring) is the best prevention against grain spoilage).

Safe moisture for normal winter storage of shelled corn is about 15%. Grain to be stored through the summer or
long term, needs to be 1 to 3 points dryer.

6. Fan Operation
20 PNEG-119 Inline Centrifugal Fan
Approximate Allowable Holding Time for Field-Shelled Corn, to Maintain Grade*
Drying fronts and/or temperature fronts move through grain at different rates depending on bin and fan
size and different moistures and temperatures.
The Table below lists the approximate time required to completely change the temperature of a bin.
Current conditions can cause this time to vary greatly. Therefore, this should only be used as a guide.
It may be necessary to run the fan only part of a day because of changing weather conditions. It would be
necessary to run it a few hours each day on several days to complete the temperature change.
Approximate Hours of Fan Time to Change Bin Temperature
1. Bushels are rounded and approximate.
2. The hours required are based on clean grain. High moisture grain and grain containing fines or foreign material will
require more time to complete the air change.
3. Not Recommended: Bins in the NR range, may require fan(s) of a different size to get the cool time into the
accepted range.
4. Bins requiring more than 100 hours of aeration to totally change the temperature may require continuous aeration at
about 1/10th CFM per bushel or some other acceptable method.
