IMPORTANT WARNING
*CAUTION - DO NOT OPERATE THIS CIRCU-FLOW WITHOUT BIN WALL
STIFFENERS, A CENTER SUPPORT FOR THE WALK-IN DOORS, OR WITHOUT THE
PROPER REINFORCED FLOOR SUPPORT SYSTEM. (See Installation Instructions.)
*KEEP YOUR BELT AND CHAIN GUARDS IN PLACE AT ALL TIMES.
*KEEP THE HOPPER SLIDE GATE CLOSED WHEN OPERATING THE CIRCU-FLOW .
*NEVER PUT MORE THAN 16 FEET OF GRAIN INTO YOUR DRYING BIN WHEN USING
THE CIRCU-FLOW. ALSO, THE GRAIN IN THE CENTER OF THE BIN SHOULD NOT BE PEAKED
- IT SHOULD ALSO NOT BE DEEPER THAN 16 FEET. If you have a 6-1/2 or 7 Ring Corrugated
Bin, do not fill any higher than one foot above the top of the 6th ring when using the Circu-Flow. You
can fill the drying bin up to the Transfer Auger for storage purposes only. Serious damage could
result if grain is stored above the Transfer Auger. Do not operate the Circu-Flow Continuous System
until you unload enough grain to attain the 16 foot grain depth.
*WHEN DRYING, BE SURE TO CAP THE UNLOADING AUGER DISCHARGE OPENING.
TAKE OFF THIS CAP WHEN UNLOADING. This cap prevents air from escaping during the drying
operation.
*MAKE SURE THE DRIVE V-BELTS ARE TIGHT. These should be checked intermittently.
*CHECK TO SEE THAT ALL GEAR BOXES HAVE GREASE OR OIL. They should be
checked during operation and before each drying season.
TIPS AND PREPARATION FOR CIRCU-FLOW OPERATION
*It will depend on you, as to the temperatures you willl use to dry your grain. The CIRCUFLOW will circulate or continuous-flow approximately 175 to 225 bushels per hour using a 3” OD
Motor Pulley on the Circu-Flow motor. This will help you to decide on the best drying temperature. If you desire more capacity, use a larger motor pulley on the Circu-Flow Motor. However,
you may then require a 7-1/2HP motor. Always keep in mind that you can now successfully dry
with high temperature heat because the Circu-Flow is always removing the dried grain from the
bottom of the bin.
*If you are drying beans, you should be using a 7-1/2HP motor instead of the 5HP motor
on the CIRCU-FLOW. You should also use a larger motor on the Transfer Auger.
*The CIRCU-FLOW will speed up your drying process as compared with conventional bin
drying methods however, the rate of drying is also dependent upon the size of your fan and
heater. DO NOT try to get by with too small a fan and heater. High volume of air movement is
veyr important. See Chart #24 in the Operating Instructions for approximate drying capacities.
NOTE: - It is important that your fan and heater be furnished with a vaporizer unit for
colder weather operation; and a plenum chamber temperature thermostat control or gas modulating valve control. These items will help to insure a constant plenum chamber temperature. Also,
because of the greatly improved flow of air through the grain and reduced static pressure, it may
be necessary for you to replace your heater orifice with one that has a larger opening to ensure
you are getting enough heat.
88
79
NOTE: - Use a 4” O.D. motor pulley on the Transfer Augers -- The Transfer Auger tends to
bind up if it is running too slow. If the Transfer Auger still binds up when you use the 4” O.D. motor
pulley, check to see that the belts are tight and not slipping. If this does not cure the problem, use
a larger motor pulley. The same principles apply to your other distribution augers which go over to
additional cooling bins.
*IMPORTANT: - During the first hours of circulator or continuous-flow operation, you may
find it necessary to hold the underbin auger to keep it from turning. The best way to do this is to
attach a pair of vise-grips to the flippers of the underbin auger and leave them attached for 50 to 75
hours of operation. This allows the bronze bearings to loosen up.
IMPORTANT OPERATING TIPS
*Fill the bin up to a 3 foot grain depth and run the system on a recirculating bases.
This will allow the TAPERED SWEEP AUGER to polish up.
*FOR CORRECT AND ACCURATE OPERATION OF AUTOMATIC CIRCU-FLOW CONTROLS, IT IS VERY IMPORTANT TO: Maintain a constant heat in your plenum chamber of the
drying bin. As the weather gets colder, this becomes harder to maintain; and without a constant
temperature in the plenum chamber, the automatic Circu-Flow controls will not operate correctly.
If your heater unit on the fan is not cycling on and off, you can be almost assured that you
are not maintaining a constant heat. Turn your thermostat down to a point where the heater is
cycling on and off at regular intervals. If you are using a modulating valve instead of a thermostat,
adjust your regulator to a point where you can be positive of maintaining a constant heat.
Then, in order to set the automatic controls in conjunction with the thermostat for the heater,
you then set the (L) Circu-Flow temperature control pointer at approximately 30 degrees to 50
degress less than the plenum chamber temperature thermostat reading.
FOR DELUXE CONTROL BOX - Turn on the control switch. Turn the Circu-Flow switch to
automatic and also turn the transfer Auger switch to automatic. When the Circu-Flow turns on
automatically, check the grain sample. If you desire wetter grain, you must set the (L) pointer at a
lower temperature setting. For dryer grain, you will set the (L) pointer at a higher temperature
setting. NOTE: - Always remember that you will remove 1 to 2 points of moisture in your cooling
process.
FOR OPTIONAL DRY-RITE dryer control - Used in addition to the Deluxe Control Box.
See Separate Manual for Installation and Manual for Operation.
IMPORTANT: MAKE DOUBLY SURE THAT YOUR V-BELTS ARE ALWAYS TIGHT -THEY SHOULD BE CHECKED INTERMITTENTLY FOR TIGHTNESS. Belt slippage can cause
serious operational problems.
80
89
* FOR CONTINUOUS-FLOW OPERATION, it is well to note that the tapered sweep auger
takes from 30 minutes to 60 minutes to travel around the bin floor; when it stops, it will always
stop near the sensing element inside the bin.
As you can see, the grain going into the cooling bin at the end of the sweep auger’s
journey will be dryer than that which went into the cooling bin at the start of the journey. Therefore, the moisture content of the grain going into the cooling bin during the journey of the tapered
sweep auger could vary as much as 3 or 4 per cent. However, if you have a spreader in your
cooling bin, this grain will all blend together and you will find that the grain in the cooling bin will
have a very consistent moisture content.
You should therefore determine an average moisture content between the grain coming off
at the start of the tapered auger’s journey, and that grain coming off at the end of the journey
when you are deciding your drying procedure.
*FOR CONTINUOUS-FLOW OPERATION with the Circu-Flow, Corn will dry most efficiently at 5 to 7 foot depths -- Milo at 3-1/2 to 4 foot depths. Your drying costs will be slightly
higher when you dry at shallower or deeper grain depths.
*YOU CAN INCREASE YOUR CIRCU-FLOW CAPACITY by using a larger motor pulley
(up to 4” O.D.) on the Circu-Flow motor; but, be careful that you do not overwork the motor. You
will need to increase your motor size to the next HP according to your bin diameter requirements.
*IF YOU ARE DRYING SOY BEANS -- You must go to the next larger HP motor with
enough starting torque to achieve the ft. lbs. of starting torque as shown on the following chart:

30’
NOTE: If you are using a system with a vertical discharge auger, you will
need to go to the next size larger motor also.
The Horse Powers shown are for corn.
*FOR BOTH CONTINUOUS-FLOW AND RECIRCULATING OPERATIONS, make sure the
circulator spreader at the top of the center vertical auger is kept free of trash build-up. This buildup can eventually stall the Circu-Flow if it is not cleaned off regularly.
*WHEN RECIRCULATING AND CONTINUOUS-FLOW DRYING (Especially during recirculating), try to use a grain cleaner when filling the bin. This will screen out the fines and trash,
otherwise, this light and fine material tends to accumulate in the center of the bin and becomes
compacted. This compacted material has a hard time flowing down into the tapered sweep auger
of the Circu-Flow and does not get recirculated properly.
If you have a problem with this compacted material in the center of the bin, much of it can
be removed thru the underbin unloading auger and can then be put back and re-distributed in the
same bin. This center material in the bin will normally flow into the unloading auger first before
any of the outer material starts flowing.
*WHEN RECIRCULATING, do not run the Circu-Flow any more than necessary as grain
damage can be incurred. Run the Circu-Flow just enough to get the dry grain off the bottom and
onto the top. To make sure that you do not overuse the Circu-Flow, the automatic temperature
sensor control should be used when recirculating the same as when using continuous-flow.
*WHEN RECIRCULATING IN COLDER WEATHER, dry your last bin of grain at as low a
temperature as is feasible. This will curtail excessive condensation and wet bin side walls. The
lower the drying heat and the more air the less bin wall condensation.
90
81
*BE SURE TO CHECK THE GREASE AND OIL OF ALL GEARBOXES (Two in the CircuFlow hopper, one on the outside vertical discharge and the transfer roof auger oil enclosed speed
reducers) TO MAKE SURE THEY ARE FILLED BEFORE EACH DRYING SEASON. The center
gear boxes in the Circu-Flow hopper should be re-greased every 100,000 bushels or at the start of
each drying season, whichever comes first. See Page 136 of this manual for greasing instructions.
FILLING
IMPORTANT NOTE: - Before putting any grain whatsoever into the drying bin, be sure to
move the tapered auger along the bin floor by hand, once around the bin floor, to make sure that
the tapered auger does not hit any obstructions.
The Auxiliary Sweep Auger, including the spur gear box, must be removed from the bin
before filling the bin with grain. The Tapered Sweep Auger can not travel around the bin if the spur
gear box or auxiliary sweep auger is still in the bin.
In order to get the best operation from your Circu-Flow, it is well to screen out the fines and
trash with a grain cleaner during the filling operation. This light material tends to accumulate in the
center of the bin and becomes compacted. Compacted material has a hard time flowing down into
the tapered auger of the Circu-Flow. This problem is more acute when recirculating than it is with
the continuous-flow operation.
The grain bin is to be filled by using the NECO Grain Spreader (See Pg. 89-94 of this
manual for Grain Speader Operating Instructions). This spreader operates independent of the
Circu-Flow. The Grain Spreader is turned on and off with a Filling Spreader Switch located on the
panel of the Deluxe Control Box. (See pg. 80-82 of this manual) This switch will operate all of the
time and is not affected by the automatic selector switch located inside of the automatic control box.
NOTE: It is important to fill the bin with 3 feet of grain before you start your fan. Without
this weight on the floor, the tremendous air flow from the fan could tilt some of the floor supports.
After spreading this initial grain in your bin, check the leveling pattern of the spreader. If the pattern
must be changed, follow the adjusting instructions in the Grain Spreader Operating Manual.
IMPORTANT NOTE: - On a new Circu-Flow installation, do not put any more that 3 feet of
grain into the bin. If any initial mechanical or installation problems show up, it is better to find this
out with a small amount of grain in the bin rather than a large amount. You can then, start the
drying process. After the grain on the bottom is dry enough to remove, start the Circu-Flow and let
it run - (Refer to Operating Procedures). After the machine has run for a while, the augers will start
to shine up. Your machine will then run smoother and will therefore, require less horsepower. This
is now a good time to check the amperage on all of your motors.
NOTE: - The Circu-Flow fluffs up the grain by its’ flowing grain principle and thereby,
greatly reduces the static air pressure. You will obtain the best efficiency from your fan and heater
when the corn is between 6 and 7 feet deep (Milo at 3-1/2 to 4 feet deep). At these grain depths,
you will not waste as much heat and air through the grain and out into the atmosphere as you
would normally with shallower grain depths. However, even when you are drying at shallower or
deeper grain depths, the Circu-Flow will out-perform other bin drying systems and methods.
Because of this lower static air pressure, it is not essential to get the grain as level when you
are filling the bin as you would normally be required in a layer drying or batch drying process

OPERATION OF THE AUTOMATIC GRAIN TEMPERATURE SENSOR CONTROL
FOR BOTH CONTINUOUS-FLOW AND RECIRCULATING OPERATION
DIAGRAM PAGE 138
The purpose of this (K) automatic grain temperature sensor control is to provide a means to
automatically detect the desired dryness of the grain at the bottom of the bin. It will automatically
turn on the CIRCU-FLOW and the Roof Auger to move this dry grain to a cooling bin (For
continusous-flow operation) or to automatically turn on just the CIRCU-FLOW to move the dry grain
from the bottom of the bin and re-distribute it onto the top of the grain (For circulator operation).
VERY IMPORTANT: The CIRCU-FLOW Automatic Controls ABSOLUTELY Will Not Work
Correctly If You Do Not Maintain A Constant Plenum Chamber Heat. You MUST maintain a CONSTANT temperature in your drying bin plenum chamber for the CIRCU-FLOW Temperature Sensor
Control to operate correctly. If your heater unit or your Fan is not cycling off and on using the
thermostat control, you can almost be assured that you are not maintaining a constant heat. You
should then, turn your heater thermostat down to a point where the burner is cycling on and off at
regular intervals. For modulating valve controls, you must be positive that you can maintain a
designated plenum chamber heat.
If the fan and heater are not drying the grain as fast as the CIRCU-FLOW can move it at
approximately 200 BPH, the temperature of the grain will not be as high as it should be and the (N)
sensing element will detect this fact. The (K) control will not allow the CIRCU-FLOW to run until the
drying operation has caught up, at which time, it will then automatically start the CIRCU-Flow.
When the dry grain at the bottom of the bin is removed, the wet grain will come down around the
(N) sensing element again, thereby automaticallly shutting off the CIRCU-FLOW. This process will
keep repeating until your grain is dry.
FOR DELUXE AUTOMATIC CONTROL BOX: (SEE PAGE 137)
In order for the (K) automatic sensor control to operate, you will have to turn the control
switch ON. Then, turn the CIRCU-FLOW switch and Roof Auger switch to automatic for the
continuous-flow operation. For circulator operation, put the roof auger switch in OFF position.
Make sure the the (P) Rubber O-Rings are at each end of the (N) temperature sensing
element. You must then place the (N) sensing element into the (M) probe bracket so that there is
approximately 1” between the (N) sensing element and the end brace bolt. DO NOT plug up the
bin wall opening which receives the (N) sensing element. The automatic control will work better if
the hot air from inside of the bin has a chance to flow past the (N) sensing element through the (M)
probe bracket and out into the outside air.
SETTING THE (L) TEMPERATURE SELECTOR POINTER TO THE PROPER SETTING:
Because of the many variables involved in drying, and that we must mount the (M) probe
bracket 10” to 12” above the perforated drying floor to allow the sweep auger wheel to pass under,
it is impossible for us to tell you exactly where to position the (L) Temperature Selector Pointer.
We can tell you that the temperature setting of the (L) pointer will be somewhat less than the
plenum chamber temperature, approximately 30 deg. to 50 deg. Therefore, the following procedure should be followed in finding the proper (L) pointer setting for the desired grain dryness.
NOTE: It is absolutely necessary that the probe from the temperature sensor sticks far
enough into the bin so that the wheel of the tapered sweep auger is between the probe and the
bin wall. This will allow the wetter grain to move down past the probe.
94
85
FOR DELUXE AUTOMATIC CONTROL BOX:
1.
Turn Control Switch, Circu-Flow Switch and Roof Auger Switch to OFF
position.
2.
Turn on your fan and heater and start drying your grain. Determine your
actual plenum chamber temperature, then set the (L) pointer at this same
temperature.
3.
Turn CIRCU-FLOW switch to “Manual”.
4.
After your fan and heater have been drying the grain for approximately 20
to 30 minutes, turn on the control switch. If the CIRCU-FLOW will not
start, the grain is still too wet. You should keep trying every 15 or 20
minutes until the CIRCU-FLOW starts.
This will allow you to take a grain sample from the center vertical spreader.
Before taking samples from the center vertical spreader, be sure to allow 1
or 2 minutes for the grain that is in the center vertical auger to empty out.
After you have enough grain for a test sample, turn off the control switch.
Repeat this process at 10 to 15 minute intervals until you get a grain
sample of the desired dryness.
NOTE: Always remember that you will remove one to two more points of
moisture in the cooling of your grain.
5.
After you get your sample of the desired dryness, immediately switch the
CIRCU-FLOW switch and Roof Auger switch to automatic. Turn the control switch “ON” for continuous-flow operation or just the CIRCU-FLOW
switch to automatic and the control switch “ON” for circulating operation.
6.
Move the (L) pointer slowly - counter-clockwise - toward a lower temperature setting until the CIRCU-FLOW turns on. This (L) pointer setting is the
correct setting for the desired dryness as determined by the previous
sampling. You should check your grain a few times intermittently in order
to check the (L) pointer setting.
7.
You can repeat the preceding procedure for any moisture content that you
so desire.
8.
If you want wetter grain, you will have to set the (L) pointer at a lower
temperature setting. Conversely, if you desire dryer grain, you will have to
set the (L) pointer at a higher temperature setting.
9.
After you have obtained the proper (L) pointer setting for a specific plenum
chamber heat and a spsecific grain dryness, you should mark all three of
these figures down for future reference.
95
86
TO OPERATE THE CONTINOUS-FLOW SYSTEM
IMPORTANT - For the Very First load that you dry with a New CIRCU-FLOW, dry
only one, three foot deep batch to make sure everything is running correctly. This
will also allow you to wear off and smooth out some of the paint on the tapered
sweep auger. If you do not do this, you could have a problem starting a new
tapered auger under deep depths of grain. After the paint is worn off of the tapered auger, you should not have any starting problems.
An extra cooling bin and a roof transfer auger from the CIRCU-FLOW bin into the
cooling bin are required along with the CIRCU-FLOW. It is Very Important to use
the belt guards for the Circu-Flow and Roof Transfer Auger. The system will start
and stop without warning when operated by the automatic controls. Be sure to
keep the hopper slide gate closed when operating the CIRCU-FLOW.
FOR DELUXE CONTROL BOX:
1.
Clutch in the (J) Jaw Clutch.
2.
Set the (L) Pointer of the (K) control at the proper setting as per
preceding instructions.
3.
Switch the Control Switch to “ON”.
4.
Switch the Roof Auger control and the CIRCU-FLOW Control to Automatic.
5.
Your grain will now be automatically moved to your cooling bin after the
grain is dry and will not require any baby-sitting. This allows you to dry
24 hours a day without anyone watching over the system. By switching
off the Roof Auger control, you can change the Continuous-Flow system
into a circulating system. By turning Off the Roof Auger, the boot near the
top of the Center Vertical Auger willl fill up with grain. The rest of the dry
grain will by-pass the boot and continue up to the circulating spreader and
will be distributed on top of the grain in the Circu-Flow bin.
If you want to run any of the roof augers by themselves to clean it out or check it,
turn the control switch to “ON” and the roof auger you want to run, to “Manual”.
TIME DELAY ON DELUXE CONTROL BOX: The Deluxe Automatic Control Box
has a built-in Time Delay for the roof augers which will allow them to clean out
after the Circu-Flow has shut off. This allows the Roof Augers to start without a
load when the Circu-Flow comes back on. The timer has a dial with five numbers
on it, each number represents approximately 20 seconds. The pointer on this dial
should be set at the corresponding number on the chart according to the size and
length of the roof auger. To reset the pointer, depress it just enough to allow it to
be moved to the appropriate notch on the dial while holding the dial from turning.
Be sure the pointer rests firmly in one of the notches on the dial or it will miss the
switch and the roof auger will continue to run.
96
87
TO OPERATE THE RECIRCULATING SYSTEM
IMPORTANT: As in the Continuous-Flow system, be sure to dry a three foot sample batch when
first starting to use a New CIRCU-FLOW. Do not wait until your bin is completely full before
starting the CIRCU-FLOW FOR THE VERY FIRST TIME. MAKE SURE to keep the hopper slide
gate closed when operating the CIRCU-FLOW.
BE SURE to use your CIRCU-FLOW BELT GUARD at all times. You must use the automatic
electrical controls with the Circulating system in the same manner as the Continuous-Flow system.
However, you must leave the Roof Auger control turned to OFF and you will have to use a slightly
different drying procedure. This procedure is as follows:
When the CIRCU-FLOW puts the dry grain from the bottom of the bin onto the wet grain at the
top of the bin, you will eventually have layers of wet grain and layers of dry grain mixed throughout your entire bin. You will have wet grain mixed with dry grain if you are filling the bin at exactly
the same time the CIRCU-FLOW is operating. It is therefore, necessary to dry this grain in two
steps:
1.
Set the (L) pointer at the correct temperature in order to remove approximately onehalf of the desired moisture removal. This procedure should continue until you
have finished your bin filling operation. After this grain is partially dried, it should
then be cooled.
2.
After you have finished filling, you should set your (L) pointer at the correct temperature in order to get your ultimate desired grain dryness. You will then let the
Automatic Controlled CIRCU-FLOW run until the whole bin of grain is dried. After
this grain has dried, it should then be cooled. If you should fill your bin before
starting your drying operation, then use the same procedure as you would for a
continuous-flow operation.
TO OPERATE AN AERATION RECIRCULATION SYSTEM
Because of the flowing grain principle created by the tapered sweep auger, you can fluff-up your
whole bin of grain with two or three hours of CIRCU-FLOW operation.
When using the Circu-Flow for aeration-recirculating, switch the (Z) selector switch to “Manual”.
This by-passes the automatic temperature sensor control. Then, turn on the (Y) Circu-Flow
switch. The CIRCU-FLOW will now continue to run until you shut it off. You can also dry your
grain WITHOUT using heat, by using the CIRCU-FLOW and your fan whenever you get low
humidity atmosphere conditions. By running the Circu-Flow for 2 or 3 hours per day and your fan
all day when the humidity is below 50%, you will actually take moisture out of your grain.
This process could be used on your last bin of grain however, it must be watched over very
closely. We recommend that you experiment with it extensively before you depend on the results
of the principle.
Be Sure that you have gas available so that you can get heat to your grain in case of any
emergency.
97 88
TO ADJUST THE CENTER VERTICAL GRAIN SPREADER SPINNER
The center vertical auger shaft to which the spinner is attached, runs at a constant speed. In
order to change the spreading pattern of the center vertical spinner, it is necessary to move or
take off the flippers that are bolted to the spinner or, you can substitute one of the extra three
furnished flippers. You will have to experiment in order to find out which flippers to use and where
to set them.
TO OPERATE UNDERBIN UNLOADING AUGER
FOR DELUXE AUTOMATIC CONTROL BOX:
1.
Refer to previous instructions for clutching procedures.
2.
Be sure to remove the cap from the Auger Discharge Opening.
3.
Turn the Control Switch to “ON”.
4.
Turn your unloading auger on and off with the CIRCU-FLOW switch. Off - Manual.

SECTION 7
CIRCU-FLOW MAINTENANCE
The Gear Boxes located in the Hopper at the Center of the bin are furnished with grease when
they are shipped to you from the factory. The center gearboxes are also equiipped with grease
fittings to facilitate future greasing.
Using a grease gun, grease all fittings every 100,000 bushels of grain or once every year, whichever comes first. Use the following procedure:
1.
Remove Hopper Covers.
2.
Grease all Grease Fittings.
3.
Rotate the outside drive pulley several rotations.
4.
Re-grease all fittings.
5.
Repeat this procedure three or four times.
As you are performing the greasing operations, grease will be pushed out of the relief plugs
located on the side of both gear boxes. This grease should be wiped off and discarded.

STARTING A STALLED CIRCU-FLOW
In some isolated cases, when belts have been slipping and wet grain is left in the center vertical
auger or if moisture or water is allowed to get into the center vertical and the unit has not been run
for some time, there will be compacted grain in the center vertical. This may prevent the CircuFlow from starting under its own power. You must break loose the wet or packed grain in the
center vertical. The following procedure is to be used:
Belts may have been slipping, which causes the tapered auger to slow down. The center vertical
auger may then become packed with grain. In this instance, tighten belts, back up the main drive
pulley as far as possible and then turn on the power. Repeat this procedure several times and if
the Circu-Flow remains stalled, use the following procedure:
NOTE:
1.
Remove Clutch Bolts (A) and engage
the spring-loaded pin (E).
2.
Insert the 5/8” Round steel bar (furnished
with the Circu-Flow) in the side hole of the
clutch (B).
3.
Then open the slide gate, take off the
discharge spout opening cover and turn on
the CIRCU-FLOW unloading auger motor.
While it is augering, move the 5/8” round
rod back and forther vigorously until you
feel some loosening. BE EXTRA CAREFUL
since you will have to do this without proper
shielding. Normally, it will require unloading

After breaking loose the packed grain in the center vertical auger, close the center
hopper slide gate, disengage the spring loaded pin (E) and replace the clutch
bolts (A). Also, recap the discharge opening.
5.
Then, run the CIRCU-FLOW on “Manual” for one or two minutes until the packed
grain is augered out ofthe center vertical
When planning to store grain in a Circu-Flow bin for an expanded period of time,
we recommend turning on the Circu-Flow and operate it in the recirculation mode
for a few minutes. This should be done periodically to eliminate start up problems
because of compaction around the sweep auger.
