READ THIS MANUAL carefully to learn how to properly use and install equipment. Failure to do so could
result in personal injury or equipment damage.
INSPECT the shipment immediately upon arrival. The customer is responsible for ensuring that all
quantities are correct. The customer should report and note any damage or shortage on the bill of
lading to justify their claim to the transport company.
THIS MANUAL SHOULD BE CONSIDERED a permanent part of your equipment and should be easily

General Safety Statement
Our foremost concern is your safety and the safety of others associated with this equipment. This manual
is to help you understand safe operating procedures and some problems which may be encountered by
the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards and precautions 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.
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.

Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wetstorage stain(rust)will developwhenclosely packedbundlesof galvanizedmaterial,such assidewall
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 sheets. 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 and spacing materials should 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 immediately about ways to minimize
the adverse effect upon the galvanized coating.

3. Decals
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fansorother air moving systems. Adequate ventilationand/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 during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.
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.

4. Assembly Instructions
Left Hand Ladder Assembly
1. Assemble platform brackets (STX-0082 and STX-0009) to stiffeners. The outer two (2) brackets
(STX-0082 and STX-0009) should sit inside of the stiffeners. The middle bracket (LDR-5362) should
attach directly to the sidewall. Holes will need to be drilled in the sidewall sheet for this bracket.
Different stiffener hole patterns may occur between two (2) different bins. The top hole of the outer
brackets should start approximately 4" below the horizontal seam. (See Figure 4A.)
NOTE: All parts in the Figure 4A are the same between the 15'-21' and 24'-36' eave platforms. The
platform bracket of the side which the ladder is to come off of should line up with a roof rib
and a roof rafter if the tank roof includes roof rafters.
