INSTALLATION INSTRUCTIONS
1. One of the most important fac-
tors for installation is providing
adequate power to run the unit.
Undersized wire can lead to
voltage drop and can cause
motor overheating and short-
ened life. Therefore, it is neces-
sary to know the distance from
the unit to available transformer
and the horsepower of your fan
unit. These two factors will de-
termine the size of wire needed
for efficient operation. See Fan
CHECKLIST BEFORE
INSTALLING THE FAN
Specifications on the following
page.
2. Grain Systems, Inc. recommends
contacting your local power com-
pany, and having a representa-
tive survey your installation so
the wiring is compatible with
their system, and adequate power
is supplied to your unit.
3. Each fan motor should be wired
through a fused or circuit
breaker disconnect switch.
4. Refer to Fan Specifications on
page 9 for the recommended
slow blow fuse or breaker size
to use when installing your par-
ticular fan.
5. Standard electrical safety prac-
tices 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 instal-
lations.
ALWAYS DISCONNECT
AND LOCK OUT POWER
BEFORE WORKING ON OR
AROUND HEATER
INSTALLATION
1. Be sure that the disconnect and
the fan are well grounded. See
machine to earth ground on
page 11.
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 nec-
essary to shim one or more cor-
ners of the foot mount to achieve
a solid mounting. Fans not sol-
idly mounted and properly
shimmed may have excess vi-
bration in them.
5. Check and retighten all electri-
cal connections. They may have
loosened in shipping.

FAN INSTALLATION
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 away.
This ground needs to be as close to
the fan as possible, but no more than
8 feet 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 pro-
vides the grounding necessary for
long life and operation of the solid
state circuit boards used on control
circuits and the electronic ignition
systems.
MACHINE TO EARTH
GROUND
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.
It is recommended that previously
installed units be checked to see that
a machine to earth ground has been
installed by an electrician.
(Ground rods and wires are not sup-
plied by Airstream). It is recom-
mended that the rod not be driven into
dry ground. The following steps en-
sure 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 pos-
sible to work the rod completely
into the ground. This method of
installing the rod gives a good

OF THE GROUND ROD
conductive bond with the sur-
rounding soil.
5. Connect the bare copper ground
wire to the rod with the proper
ground rod clamp.
6. Connect the bare ground wire to
the fan control boxes with a
grounding lug. See Figure 3.
7. Ground wire must not have any
breaks or splices. Insulated
wire is not recommended for
grounding.
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.

12
FAN OPERATION
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 in-
structions on the motor.
Proper installation and start-up
ensures many years of trouble-free
operation.
START-UP
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 con-
tribute to spoilage. Wet, warm grain
promotes insect growth as well as
GRAIN STORAGE
Average grain temperature should
be above 35°F in the winter and be-
low 65°F in the summer. Always try
to keep the grain within 10-15°F of
the average monthly outside tem-
perature. This means grain may
need to be aerated on warm days
during the winter to stay above 35°F
when freezing temperatures are pre-
dominate. 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 your local Agriculture
Extension Office or State Ag. Univer-
sity for more exact guidelines.
If the grain is to be stored more
than one year, it has to be recooled
the following fall and winter, repeat-
ing the process as long as the grain
is in storage. Frequent and regu-
lar inspection (at least weekly
during fall and spring) is the best
prevention against grain spoilage).
grain spoilage. Cool, dry grain can
keep for long periods of time.
It is recommended that the grain
be kept cool (avoid freezing as freez-
ing can reduce quality). Grain should
be cooled through the fall and winter,
warmed in the spring and summer.

•Bushels are rounded and approximate.
•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.
•Not Recommended: Bins in the NR range, may require fan(s) of a different size to get the cool time into the
accepted range.
•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.

Motors used in Airstream fan units
are all standard NEMA frame motors
and are specially designed for use in
crop drying applications. Most of the
replacement parts for these motors are
handled by authorized service stations
of the various motor manufacturers.
1. Always disconnect and lock out
power before working on or
around fan motor and electrical
components.
2. Malfunctioning electrical com-
ponents should be checked
by a qualified electrician.
3. For extra motor life, any elec-
tric motor should be run for 30
minutes, once a month. This
will help eliminate any damag-
ing moisture build-up in the
motor and bearings.
4. If excess vibration shows up
at some point when the fan has
been running smoothly, check
the blade for these conditions:
a. Fans setting idle in the sum-
mer offer an excellent place
for mud dobbers to build
their nests. A mud dobber
nest on the back of the fan
blade will cause the fan to
be out of balance and vibrate.
b. Also, mice have been
known to nest in the back
of a blade. When the fan is
started the centrifugal force
kills the mice, but throws the
blade out of balance.

LUBRICATION
This is a ball bearing motor. The
bearings have been given initial lu-
brication at the factory. Motors with-
out regreasing capability are factory
lubricated for normal bearing life.
RELUBRICATION
INTERVALS (MOTORS WITH
REGREASING CAPABILITY)
New motors having been in storage
for over a year should be relubricated
by the procedure noted in the chart to
ensure long operating life.

LUBRICANT
Baldor motors are pre-greased nor-
mally with Shell Oil Company's
"Dolium R". Several equivalent
greases which are compatible with
the Baldor furnished grease are
Chevron Oil's "SRI No. 2" and
Texaco Inc.'s "Premium RB".
PROCEDURE
is equipped with Alemite fitting,
clean tip of fitting and apply grease
gun. Use 1 to 2 full strokes on mo-
tors in NEMA 215 frame and smaller.
Use 2 to 3 strokes on NEMA 254 thru
NEMA 365 frame. Use 3 to 4 strokes
on NEMA 404 frames and larger. On
motors having drain plugs, remove
grease drain plug and operate mo-
tor for 20 minutes before replacing
drain plug.
On motors equipped with slotted
head grease screw, remove screw
and apply grease tube to hole. Insert
2 to 3 inch length of grease string into
each hole on motors in NMEA 215
frame and smaller. Insert 3 to 5 inch
length on larger motors. Motors hav-
ing grease drain plugs, remove plug
and operate motor for 20 minutes be-
fore replacing drain plug. Keep
grease clean. Lubricate motors at
standstill. Remove and replace
drain plugs at standstill. Do not mix
petroleum grease and silicone
grease in motor bearings.
Overgreasing bearings can cause
premature bearing failure. If motor
