Warning
Water Sensitive Materials - Read this notice carefully
Bundles must be inspected and carrier advised immediately if damage is noted. White rust is a
corrosion attack of the zinc coating resulting from the presence of water. Anywhere rust is
found will result in a reduction of the life of the galvanized steel.
If water has entered a bundle or if condensation has formed between items, the bundle must be
opened, the items separated and all surfaces dried.
If items are to be installed within 10 days:
Store bundled items off the ground high enough to allow air circulation beneath bundle and to
prevent water from entering. Store 1 end at least 8” (20.32cm) higher than the opposite end.
Support long bundles in the center. Prevent rain from entering the bundle by covering with a
tarpaulin, making provision for air circulation between the draped edges and the ground.
Do not wrap in plastic.
If items are not to be installed within 10 days:
Provide inside dry storage. Storage beyond 6 months is not recommended. If white rust is
apparent upon receipt of shipment, notify Chief immediately. Damage to items, resulting from
improper storage, is the responsibility of the receiver.

Accessory Equipment
All accessory equipment should be installed and maintained in accordance with each individual
supplier’s installation and operation instructions. However, if any modifications to the Chief
standard design are required, contact Chief for special recommendations.
Important Note: Do not modify equipment without Chief approval. It is the responsibility of the
general contractor to verify that all equipment is properly installed and that the equipment is
compatible with the intended use. A qualified electrician should be contracted to complete all
electrical wiring and servicing.
General Contractor Responsibilities
It is the responsibility of the general contractor to verify that the complete support system and
other accessory equipment is constructed with quality workmanship and that all equipment is
installed per the respective manufacturer's instructions.
In addition, the general contractor is responsible for the fitness of use of any system which he
constructs. All accessory equipment incorporated into the system should be approved for the
intended use by each respective equipment manufacturer.
Field Modifications and Installation Defects
Chief assumes no responsibility for field modifications or installation defects which result in
structural damage. If any field modifications are necessary which are not specifically covered
by the contents of the installation manual, contact Chief for approval. Any unauthorized
modification or installation defect which affects the structural integrity of the support system will
void the warranty.
Checking Shipment
For your convenience steel components will be color coded, individual items labeled with an
appropriate part number and packages labeled. Hardware, including bolts, nuts, screws and
other small clips or brackets may be divided into smaller packages for ease of use and
identification.
Check your shipment at the time of delivery against the packing list provided with the shipment.
If any items are missing or any damaged material is evident, note such shortage or damage on
the freight bill before you sign the shipment paperwork.
Claims of shortages will not be honored after 30 days from receipt of shipment. Parts that are
missing or damaged are the responsibility of the delivering carrier, not the manufacturer or
dealer.
It is advisable to reorder damaged or missing parts immediately so that there will be no delay in
the bin installation. After receiving the invoice for the reordered material, file a claim with the
delivering carrier immediately.

Chief Industries, Inc. 800-359-7600 INTRODUCTION -9621144 Page 13
Suggested Equipment
Chief recommends the following equipment and tools needed for installation of the grain storage
bin. Individual installations may vary.
Impact wrenches and sockets
End wrenches
Crescent wrenches
Vise grip pliers
Alignment punches
Rubber mallets
Level
Crane Weight Capacity
Verify the total dead load by referring to the corresponding manual addendum for your
application. This weight includes all structural members and included hardware.
When determining the crane capacity necessary to install the support structure, the boom
distance must be considered. If a single crane will not lift the support structure two cranes may
be used, utilizing a spreader bar. The spreader bar must be adequately designed to carry the
entire dead weight.
Important Note: Overloading the crane capacity can result in substantial property damage and
severe personal injury. Always verify crane capacity prior to lifting.

E A V E T O W E R
Chief Industries, Inc. 800-359-7600 P/N - 621144 Page 14
Hardware Torque
All components are assembled using SAE grade hex head bolts with corresponding washers
and nuts. Bolts are marked with radial lines on the bolt head as shown in the following
illustration.
Do not substitute any other bolt type or grade. Use only the bolts supplied by Chief. The
substitution of bolts from other sources is not permitted and will void the warranty.
When installing hardware the minimum and maximum torque values shown below must be
followed. All hardware must seat tight against the corresponding bin component.

Concrete Design and Construction
Foundation designs are based on the allowable soil bearing capacity of the undisturbed soil and
should be certified by a licensed engineering firm. Using soil borings to determine the allowable
soil bearing capacity, a professional engineer will need to be employed by the contractor to
design the foundation accordingly. Foundation designs must be approved by a licensed
engineer in order to meet local governing building codes and local soil and weather conditions,
including seismic and wind loading requirements. Tower dead load, compression and uplift per
post, overturning moment at the foundation and horizontal shear per post is available from Chief
upon request.
Non-uniform settlement of the foundation can cause severe structural damage to the structure
and foundation. An improperly designed or constructed foundation will void all aspects of the
warranty. It is the responsibility of the general contractor to verify that an adequate foundation
is provided.
Important Note: Faulty concrete construction or shim omission will void the warranty.

Installation
Part Identification
The following is a general outline provided for reference only.
Important Note: Prior to starting the installation it is very important to plan ahead and by
verifying the order and location of all components.
Verify the correct tower type / style by looking at the weld dots located near the end of the tower
posts.
Important Note: Leave all hardware loose until all components have been added. This will
allow for proper alignment of components and ensure that tolerances do not accumulate.
