Planning the Model 108 Feed Delivery System
Carefully plan the Model 108 Fill System installation. Make sure the system will not interfere with other
equipment, doors, windows, etc.
The charts below provide power unit recommendations and maximum system line lengths. The top chart applies
to standard 348 RPM systems. The lower chart applies to (optional) High Capacity 425 RPM systems.
*Maximum line lengths should be reduced for elevations over 8’ (2.4 m) and/or inclines steeper than 45 degrees.
Maximum lengths for 108 systems include use of two PVC elbows. If additional elbows are used, decrease line
length by 30 ft. (9 m) per elbow. Length of extension systems do not include elbows. Decrease maximum
extension system lengths by 30 ft. (9 m) per elbow if used in the system.
Horsepower requirements are based on length of the Model 108 FLEX-AUGER system and type of system
installed--i.e. number of turns.
See “Model 108 Bin Placement Chart” on page 14 through page 18 for typical bin to building placement using
various elevations, boots, and screener options.
1.For the easiest installation and most trouble-free operation, locate the feed bin in a direct line with the FLEX-
AUGER Feed Delivery System. The layout charts “Model 108 Bin Placement Chart” on page 14 and
“Model 108 Bin Placement Chart (with In-Line or Rotated Screeners)” on page 15 provide some points
of reference for bin placement according to the height at which the FLEX-AUGER tube enters the building.
Remember, these are only examples. The layouts can be modified by changing the elbows, the tube sections,
and/or the distance from the bin to the building.
FLEX-AUGER Feed Delivery Systems operate best at an angle of no more than 60 degrees from horizontal
to the entry of the building at the desired height. Chore-Time considers a 45 degree elevation to be standard.
The lower the angle, the more reliable the system.
2.Lay out the system as straight as possible. Avoid extra elbows and curves by locating the feed bin in line with
the feeders. One horizontal 90 degree turn is permissible inside the building. 180 degree turns are not
recommended under any conditions.
If additional turns or elbows are required, use an Extension Boot. Remember: one 90 degree elbow requires
the same power as 30’ (9.1 m) of straight line.
3.Plan the system so that the auger tubes are directly over the feeders or hoppers to be filled, if possible. The
drop tubes may be angled to a maximum of 45 degrees from the vertical if necessary. At angles greater than
45 degrees, bridging in the drop tubes may occur.

4.The control unit must be located over a feeder or hopper that will require as much or more feed than any of
the other feeders or hoppers. If frequent filling is desired, mount the drop tube switch or hopper level switch
low so that this feeder or hopper will have a low feed level. This allows the feeder to call for feed more often,
the system will restart, and the other feeders will be refilled sooner.
5.Do not locate outlet drops on or just before an elbow. Install the drop after the elbow so feed will cushion the
auger through the curve. If there is some reason why the outlet drop cannot be moved, it must have some
"feed bypass" to cushion the auger through the elbow.
6.Avoid horizontal left-hand turns if possible. The elbow in a left-hand turn is not cushioned by the feed and
will wear faster. On systems with a 90 degree horizontal left-hand turn, reduce the stretch to reduce wear.
A rule of thumb for left-hand turns is to reduce stretch to 6" per 50’ (150 mm per 15 m) of auger on
initial installation. After the system has been broken in, it may be necessary to increase the auger
stretch to prevent auger surging.
7.On any Extended Length System, balance the power requirements between the power unit that takes feed
from the bin and the power unit on the Extended Length System.
To do this, determine the total length of the system and divide by two. Subtract 20’ (6.1 m) from the standard
system and add 20’ (6.1 m) to the extended system.
Example: On a 240’ (73 m) system, the center of the system would be 120’ (36.5 m). Subtract 20’ (6.1 m)
from standard system, and add it to the extended length system. The first power unit should be located
approximately 100’ (30 m) down the system. Locate the second power unit approximately 140’ (42.7 m)
from the first power unit.

The FLEX-AUGER Delivery Systems may be readily adapted to most feed delivery applications. The systems
illustrated on the following pages show the most common types of FLEX-AUGER installations. These diagrams
provide guidelines for laying out your system.
See “Systems Not Allowed” on page 13 to see four systems that are NOT recommended. Possible alternate
systems are provided with each non-recommended system.
System A represents a typical straight-line system with optional tandem bin set-up. If this were a long system with
many outlet drops, some feed bypass should be provided by increasing the size of the outlet holes, from small at
the bin end, to the large at the control end of the line.
System B represents an extended length system. Equalize the power requirements of each part of the system.
Optional equipment required.
System C represents a twin boot system with the feed bin centered at one end of the building.
Planning

Planning FLEX-AUGER® Feed Delivery System
12 MA1032F
System D utilizes right-hand 90 degree turns. The elevations should be accomplished within the outside elbows.
This system would be recommended over system E since it eliminates additional elbows and left hand turns.
System E uses one additional 90 degree elbow after entering the building. Note that the elbows are left-hand turns.
This system would be improved if the feed bin was moved to the opposite side of the building to provide right-
hand turns instead.
System G represents an extended length system with one additional 90 degree elbow. This is acceptable, but
Systems C or D would be recommended (to reduce excessive run time). Optional equipment required.

Systems Not Allowed
NOT ALLOWED. System H is not recommended, due to
180 degree, left-hand turns. Erratic auger operation would be
expected. The feed bin should be relocated or an Extension
Hopper should be utilized as in System G.
NOT ALLOWED. System I is not recommended, due to
180 degree, left-hand turns. Excessive elbow wear and
erratic auger operation would be expected. Systems D, E, or
G would be recommended.
NOT ALLOWED. This system uses 180 degree elbows
and would be subject to premature elbow wear due to
outlet drop placement before an elbow. System C would
be recommended.
NOT ALLOWED. Too many elbows. The result would
be auger vibration, motor stall, and excessive elbow wear.
A twin system, such as C, D, or E, would be
recommended; or an Extension Hopper could be utilized
as in System G.

Model 108 Bin Placement Chart
Use this chart to determine the distance from building to center of bin ("X") at the various entrance heights ("H")
and degrees of elevations listed below.
Degree of elevation = Angle at which the system is installed, including the 30 degree or straight-out Upper Boot.
These layout charts are for planning and reference purposes only. A combination of elbows and straight tube may
be required for your installation, depending on the distance from the bin to the building and the height at which
the auger tubes are to enter the building. The elbows may be easily cut to any angle required.
PAY PARTICULAR ATTENTION TO THE MINIMUM DISTANCE BETWEEN THE BIN AND THE
BUILDING.
Many installation and operational difficulties can be avoided if the bin is located farther from the building. If in
doubt, it is BETTER TO BE TOO FAR AWAY THAN TOO CLOSE.
The maximum recommended angle of elevation above the horizontal is 60 degrees. The maximum elevation is 30
feet (9.1 m) . . . if the angle of elevation is no more that 45 degrees.
All systems require adequate support of the auger tubes to prevent sagging and/or excessive forces being
transmitted to the bin boot.

Bin Location
For easiest installation and most trouble-free operation, locate the feed bin directly in line with the FLEX-AUGER
System. The layout charts on Page 14 and Page 17 provide some points of reference for bin placement according
to the height at which the system enters the building. The 30 degree or straight-out boots combined with various
elbow hookups offer a wide range of possibilities. The charts are only for reference. Modify and adjust elbows
and tube sections as needed.
NOTE: Two 45 degree PVC elbows are standard with Model 108 FLEX-AUGER Delivery Systems. If additional
elbows are required they must be ordered separately.
The bin collar is installed during bin assembly. Chore-Time bins have a welded collar. Bin Adapter Kits are
available to modify existing bins so that the welded collar can be used. In addition, a Universal Adapter Plate is
available to allow the FLEX-AUGER boot to be installed to other manufacturers’ bins.
Tighten all bin-seal bolts from the nut side. This prevents cutting and "spinning out" of the plastic washer.
Boot Installation
1.Insert the upper boot into the bin collar and turn it to line up with the direction that the auger line will go. The
boot must be as far up into the opening as it will go. Use the holes in the ring for drilling guides and drill 11/
32" (8.8 mm) holes in the upper rim of the boot. Attach the boot to the bin collar with the hardware provided.
(See Figure 1.)
IMPORTANT: Failure to install the hardware as shown in Figure 1 may cause breakage of the red
boot body.
2.Attach the transfer plate to the upper boot. Use truss head bin-seal bolts installed from the inside of the plate,
with flat washers placed under the nuts.
3.Insert the slide into the transfer plate slot so that it is in its operating position before bolting the slide shield in
place. Remove the paper backing from the sealing strip before fastening the slide shield to the transfer plate.
Use two 5/16-18 x 3/4" hex head machine screws to secure the shield.
4.Bolt the lower boot to the transfer plate using four 5/16-18x3/4" hex head machine screws.
5.After the auger tubes and auger have been installed, attach the 6197 Clean-Out Cover Plate or the optional
Proximity Boot Switch to the lower boot.

Auger Tube Installation
The FLEX-AUGER Delivery System includes two 45 degree elbows as standard equipment. These elbows are
used to make up the sloping portion of the auger line at the feed bin, and elsewhere in the system if necessary. If
additional elbows are required they should be ordered separately. Figure 2 shows how the elbow can be cut into
shorter sections.
1.Determine where the entrance hole for the auger tube must be located on the building and cut it.
2.If necessary, cut the elbow used where the auger enters the building. Slide the seal ring and neoprene seal
over the straight end of the elbow and place it in the hole cut in the building, with the belled end outside the
building. (See Figure 3.) Clamp the belled end of the second elbow on the outlet end of the boot on the feed
bin.
3.Place the straight end of a tube section inside the belled end of the elbow in the building. Hold the straight
section of auger tube so that it touches the elbow on the boot. Mark the spot where the tube touches the boot
elbow and cut the elbow at that point.
4.Place the belled end of the auger tube over the end of the elbow just cut, and hold the tube against the top
elbow. Mark and cut the straight auger tube so that it will fit between the two elbows.
Remember to cut the auger tube long enough to fit inside the belled end of the elbow in the building.

Note: In some installations it may be possible to eliminate the elbow on the boot, using only a straight
auger tube and one elbow where the auger tube enters the building.
5.Dry-fit all parts. When satisfied that elbows and tubes fit together smoothly, glue with PVC cement
according to the instructions on cement container and/or on Page 49 of this manual.
6.ALL TUBE JOINTS EXPOSED TO MOISTURE AND WEATHER MUST BE SEALED OR CAULKED
TO WATERPROOF THEM IN ADDITION TO CEMENTING OR CLAMPING THE JOINT.
7.If there are more than 15 feet (4.5 meters) of auger tube between the boot and the building, provide
additional support for the tubes so that the boot does not carry the weight of the auger. Extra support can be
achieved with cables or chain fastened to the bin legs and the auger tube.
8.Locate and cut the outlet holes as required and specified in the instructions on Page 20.
9.Slide (2) Outlet Insert Rings onto the pipe at each outlet hole location.
Each Outlet Assembly is shipped with Insert Rings for both steel and PVC pipes.
The 3/8" (10 mm) thick rings are for steel tube systems. The 1/4" (6 mm) thick rings are for PVC tube
systems. Be sure to use the appropriate Insert Rings for your system.
10.Install the remaining tubes in the system.
The PVC auger tubes should be fastened together using PVC cement.
Model 108 Tube connectors should be used to connect steel auger tubes.
Outlet Drop Installation
Cut the outlet hole in the auger tube. A sabre saw or hacksaw is handy for making the cuts when total feed dropout
is desired. (See Figure 4.) Use a file to remove burrs from opening.
Note: For total feed drop out, outlet holes should be 5-3/8" (137 mm). If some feed carry over is required, outlet
holes should be 3-1/2" (90 mm).
