2. Safety
This product has sharp edges, which may cause serious injury. To avoid injury, handle
sharp edges with caution and always use proper protective clothing and equipment.
General Safety Statement
Our foremost concern is your safety and the safety of others associated with grain handling equipment.
This manual is to help you understand safe operating procedures and some problems that may be
encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards, and precau tions exist
and inform all personnel associated with the equipment or in the area. Safety precautions may be required
from the personnel. Avoid any alterations to the equipment, which may produce a very dangerous
situation, where SERIOUS INJURY or DEATH may occur.
You should consider the location of the bin site relative to power line locations or electrical transmission
equipment. Contact your local power company to review your installation plan or for information
concerning required equipment clearance. Clearance of portable equipment that may be taken to the bin
site should also be reviewed and considered. Any electrical control equipment in contact with the bin
should be properly grounded and installed in accordance with National Electric Code provisions and other
local or national codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall
bundles is laying horizontally with the arch of the sheet upward, like a dome. Sidewall sheets stored on
edge must be secured so that they cannot fall over and cause injury. Use care when handling and moving
sidewall bundles.
Personnel operating or working around equipment should read this manual. This manual must be
delivered with equipment to its owner. Failure to read this manual and its safety instructions is a
misuse of the equipment.

2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it must not be allowed to remain between the she ets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking an d spacing mat erials sho uld not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer imme diately about ways to minimize
the adverse effect upon the galvanized coating.

Roof Damage Warning and Disclaimer
The manufacturer does not warrant any roof damage caused by excess ive v acuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air”
devices should be provided for all powered air handling systems. The manufacturer does not
recommend the use of downward flow systems (suction). Severe roof damage can result from
any blockage of air passages. Running fans durin g high humidity/cold weather conditions can
cause air exhaust or intake ports to freeze.
CAUTION!
3. Decals
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.

Flowing material will
trap and suffocate.
Crusted material will
collapse and suffocate.
Keep clear of all augers.
DO NOT ENTER this bin!
Failure to heed these
warnings will result in
serious injury or death.
If you must enter the bin:
1. Shut off and lock out all power.
2. Use a safety harness and safety line.
3. Station another person outside the bin.
4. Avoid the center of the bin.
5. Wear proper breathing equipment or respirator.

Tie Bar Detail
1. Locate the tie bars between the rails. (Spaced evenly throughout the system.)
NOTE: Tie bars are to be placed at the end of monorail, at each splice and in the middle of the rail
if it is over 16' long. (Not necessarily evenly spaced.) Rail spacing details on Pages 26-41,
detail tie bar placements in each layout.
2. A single #10 x 5/8" self-drilling screws may be used to fasten the tie bars at each end to the rails
as necessary. (See Figure 4B.)
Figure 4B Tie Bar Detail
3. Tie bars should overlap and connect each rail to the next rail. Tie bars should be located along
each side of a rail splice and around the perimeter of the bin, no more than 6" from the end of the rail.
(See Figure 4C.)

4. Monorail Installation
Tie Strap Detail
1. Tie straps should be used when a tie bar cannot be used to connect rails together due to special
spacing of monorail. Tie strap should be connected to all three (3) rails using self-drilling screws.
(See Figure 4D.)
2. Tie straps are to be located in the same places as a tie bar would be used.
NOTE: Some tie straps will be used to support center well and intermediate well assembly.
(See Figure 5F on Page 24 and Figure 5G on Page 25.)

Spacing depends on
eave height.
Assembling Legs to Rail
1. Place two (2) corners of the monorail leg into the rails as shown.
2. By twisting the leg it will spread the rail enough to get the other corners inside.
3. The leg can then be pushed down into the rail until the tabs lock it into place. (See Figure 4E.)

4. Monorail Installation
Monorail “Rail and Leg Spacing”/“Full Floor Leg Quantity” for 78' Bin Diameter
3' Sections of monorail should be placed around the perimeter of the bin. Monorail legs for perimeter rails
should be spaced 16" apart on center. (See Figure 4F.)

4. Monorail Installation
Splicing Rails
1. A leg must be centered at each rail splice.
2. The closest leg may be moved a few inches over to center it under the splice. If more than 3" of
movement is required to center the leg under the splice, add an additional leg.
3. Fasten the rail to the leg with two (2) #10 self-drilling screws (splice locations o nly). (See Figure 4G.)

Floor Splice Details
Some of the floor planks will need to be spliced together. (See Figure 5F on Page 24 and plank layout
on Page 45 and plank length chart on Page 46.) Install plank length A first, then in stall the corresponding
plank length B. Continue until floor is complete. Center and install two (2) splices (PCL-7009) at each plank
splice location using self-drilling screws. Use eight (8) screws at the end of the splice for each plank,
four (4) on each side. (See Figure 5A belowand Figure 5B on Page 22.)

Flashing Installation
Figure 5C
Formed Flashing Installation
If bin sweep auger is to be used, overlap flashing such that rotation (usually clockwise) of the sweep will
climb up on the next flashing section. (See detail C in Figure 5C.) This will prevent the rotating/slipping
outer wheel of the sweep from catching on the flashing edges.
After the floor is in place, lay the flashing pieces on top of the floor place over the 1-1/4" bin bolts.
See Figure 5D and Figure 5E on Page 23 to determine the correct sequence for placing the nuts and
washers. Finger tighten the nuts. While holding flashing flat, fasten the flashing to the floor with sheet
metal screws. Now tighten flashing nuts.
