INSTALLATION INSTRUCTIONS

1. One of the most important fac-tors for installation is providingadequate power to run the unit.Undersized wire can lead tovoltage drop and can causemotor overheating and short-ened life. Therefore, it is neces-sary to know the distance fromthe unit to available transformerand the horsepower of your fanunit. These two factors will de-termine the size of wire neededfor efficient operation. See Fan

CHECKLIST BEFOREINSTALLING THE FAN

Specifications on the followingpage.

2. Grain Systems, Inc. recommendscontacting your local power com-pany, and having a representa-tive survey your installation sothe wiring is compatible withtheir system, and adequate poweris supplied to your unit.

3. Each fan motor should be wiredthrough a fused or circuitbreaker disconnect switch.

4. Refer to Fan Specifications onpage 9 for the recommendedslow blow fuse or breaker sizeto use when installing your par-ticular fan.

5. Standard electrical safety prac-tices and codes should be used.(Refer to National Electrical CodeStandard Handbook by NationalFire Protection Association).

6. A qualified electrician shouldmake all electrical wiring instal-lations.

ALWAYS DISCONNECT

AND LOCK OUT POWER

BEFORE WORKING ON OR

AROUND HEATER

INSTALLATION1. Be sure that the disconnect and

the fan are well grounded. Seemachine to earth ground onpage 11.

2. Rotate the fan blade to be surethat it revolves easily and doesnot rub the housing.

3. Check all fasteners on motormounts, fan blades and otherbolted items to make sure theyare tight. If any are loose, checkfor proper clearance and re-tighten fasteners. They mayhave loosened in shipping.

4. Fans should be mounted to setlevel and solid. It may be nec-essary to shim one or more cor-ners of the foot mount to achievea solid mounting. Fans not sol-idly mounted and properlyshimmed may have excess vi-bration in them.

FAN INSTALLATION

It is very important that a machineto earth ground rod be installed atthe fan. This is true even if there isa ground at the pole 15 feet away.This ground needs to be as close tothe fan as possible, but no more than8 feet away. The ground rod shouldbe connected to the fan control panelwith at least a #6 solid bare copperground wire, or in accordance withlocal requirements. The machine toearth ground provides additionalsafety if there is a short. It also pro-vides the grounding necessary forlong life and operation of the solidstate circuit boards used on controlcircuits and the electronic ignitionsystems.

MACHINE TO EARTHGROUND

Dig a hole large enough to hold 1or 2 gallons of water. Work the

ground rod into the earth until it iscompletely in the ground.

It is recommended that previouslyinstalled units be checked to see thata machine to earth ground has beeninstalled by an electrician.

(Ground rods and wires are not sup-plied by Airstream). It is recom-mended that the rod not be driven intodry ground. The following steps en-sure proper ground rod installation:

1. Dig a hole large enough to hold1 to 2 gallons of water.

2. Fill hole with water.

3. Insert rod through water and jabit into the ground.

4. Continue jabbing the rod up anddown, the water will work its waydown the hole, making it pos-sible to work the rod completelyinto the ground. This method ofinstalling the rod gives a good

conductive bond with the sur-rounding soil.

5. Connect the bare copper groundwire to the rod with the properground rod clamp.

6. Connect the bare ground wire tothe fan control boxes with agrounding lug. See Figure 3.

7. Ground wire must not have anybreaks or splices. Insulatedwire is not recommended forgrounding.

Figure 3: 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.

FAN OPERATION

On initial start-up of the fan, run itmomentarily to make sure that thefan blade is rotating in the properdirection and airflow is correct. If not,change motor direction using in-structions on the motor.

Proper installation and start-upensures many years of trouble-freeoperation.

START-UP

MAINTAINING GRAINQUALITY

To properly maintain the quality ofstored grain, it is necessary to keepthe grain dry, cool and insect free.Any one of these problems can con-tribute to spoilage. Wet, warm grainpromotes insect growth as well as

GRAIN STORAGEAverage grain temperature shouldbe above 35°F in the winter and be-low 65°F in the summer. Always tryto keep the grain within 10-15°F ofthe average monthly outside tem-perature. This means grain mayneed to be aerated on warm daysduring the winter to stay above 35°Fwhen freezing temperatures are pre-

dominate. During the summer it maybe necessary to aerate the grain oncool nights, so the 65°F temperatureis not exceeded during the hot daysof summer.

Conditions and requirements mayvary from area to area. We suggestthat you contact your local AgricultureExtension Office or State Ag. Univer-sity for more exact guidelines.

If the grain is to be stored morethan one year, it has to be recooledthe following fall and winter, repeat-ing the process as long as the grainis in storage. Frequent and regu-lar inspection (at least weeklyduring fall and spring) is the bestprevention against grain spoilage).

grain spoilage. Cool, dry grain cankeep for long periods of time.

It is recommended that the grainbe kept cool (avoid freezing as freez-ing can reduce quality). Grain shouldbe cooled through the fall and winter,warmed in the spring and summer.

Motors used in Airstream fan unitsare all standard NEMA frame motorsand are specially designed for use incrop drying applications. Most of thereplacement parts for these motors arehandled by authorized service stationsof the various motor manufacturers.

1. Always disconnect and lock outpower before working on oraround fan motor and electricalcomponents.

2. Malfunctioning electrical com-

ponents should be checkedby a qualified electrician.

3. For extra motor life, any elec-tric motor should be run for 30minutes, once a month. Thiswill help eliminate any damag-ing moisture build-up in themotor and bearings.

4. If excess vibration shows upat some point when the fan hasbeen running smoothly, checkthe blade for these conditions:

a. Fans setting idle in the sum-mer offer an excellent placefor mud dobbers to buildtheir nests. A mud dobbernest on the back of the fanblade will cause the fan tobe out of balance and vibrate.

b. Also, mice have beenknown to nest in the backof a blade. When the fan isstarted the centrifugal forcekills the mice, but throws theblade out of balance.
