remains above this outlet.
• Side floor outlets to be used ONLY when above condition
is satisfied.
• Lock all side floor outlets to avoid accidental premature
use.
• See manufacturers instructions for proper use of factory
supplied sidedraw (wall) discharge systems.
ST-0060–1
Install and Operate Electrical Equipment Properly
• Electrical controls must be installed by a qualified electrician
and must meet the standards set by applicable local codes
(National Electrical Code for the US, Canadian Electric
Code, or EN60204 along with applicable European Direc-
tives for Europe).

— Do not try to light any appliance.
— Extinguish any open flames.
— Do not touch any electrical switch.
— Immediately call your gas supplier. Follow the gas suppli-
er’s instructions.
— If you cannot reach your gas supplier, call the fire
department.
• The use and storage of gasoline and other flammable vapors
and liquids in open containers in the vicinity of this appliance
is hazardous.
• Improper installation, adjustment, alteration, service or main-
tenance can cause property damage, injury or death. Read
the installation, operating and maintenance instructions thor-
oughly before installing or servicing this equipment. Installa-
tion and service must be performed by a qualified installer,
service agency or the gas supplier.
ST-0024–1

Chapter 1: Safety Precautions
Handle and Use Equipment Properly
• Equipment is intended for the use of grain drying only. Any
other use is a misuse of this equipment.
• The operating instructions in this manual pertain to the
common cereal grains as indicated. When drying any other
grain, contact GSI for additional recommendations.
• On LP fired units, set pressure regulator to avoid excessive
gas pressure applied to the burner during ignition and opera-
tion. Do not exceed maximum recommended drying
temperatures.
• Equipment has sharp edges that can cause serious injury. To
avoid injury, handle sharp edges with caution and use proper
protective clothing and equipment at all times.
• All guards must be in place before and during operation.
Images of guards removed in this manual are for illustration
purposes only.
• Use caution when working around high-speed fans, gas
burners, augers and auxiliary conveyors which can start
automatically.
• Keep hands, feet, and clothing away from moving parts.
• Do not bypass any safety device or interlock.
• Do not enter the dryer or bin while it is operating.
• Do not operate in an area where combustible material will be
drawn into the dryer.
ST-0029–2
Store Bin Sheets Properly
• Sidewall bundles or sheets must be stored in a safe manner.
The safest method of storing sidewall bundles is by laying
them 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.

Chapter 1: Safety Precautions
Maintain Equipment and Work Area
• Understand service procedures before doing work.
• Keep area clean and dry.
• Do not service equipment while it is operating. Disconnect
and lock-out power and fuel supply before entering equip-
ment or before performing maintenance.
• Keep your equipment in proper working condition. Replace
worn or broken parts immediately.
• Depressurize the fuel train before disassembling for service.
• Allow the fan to operate for 20 minutes with the burner off to
purge products of combustion and to cool the components
before entering.
• Check regularly for any developing gas plumbing leaks. Do
not operate the dryer if any gas leak is detected. Shut down
and repair before further operation.
ST-0030–2
Install and Operate Equipment Properly
• Make sure grain chutes are empty by performing a manual
dump before entering the bin.
• Before attempting to remove and reinstall the fan blade, con-
tact GSI for the recommended procedure.
ST-0031–2
Do Not Overfill TopDry
• Do not overfill TopDry. Stored grain must be no higher than
the heater duct opening.
• Filling the bin above this point will cause a blockage of the
ducts.
ST-0062–1
PNEG-4936 36 Ft. TopDry Autoflow 13

Chapter 1: Safety Precautions
Exercise Caution When Drying Flammable Grains
• Be aware that some grains are highly flammable including,
but not limited to, rapeseed, canola, linseed, sunflower and
milo.
• All grain and seed must be whole (minimal cracking or crush-
ing), clean, and dust free before drying.
• Avoid dust and chaff from being drawn into the fan and
heater.
• To reduce risk of fire, keep the fan, heater, drying plenum,
and ducts clean at all times.
• In the event of a fire (or suspected fire):
1. Shut down the entire dryer.
2. Turn off the fuel at the tank or supply valve.
3. Shut off and lock electrical power.
4. Evacuate the area.
5. Call the fire department.
ST-0032–1
Rotating Auger Hazard
• Keep clear of rotating augers and
moving parts.
• Do not remove or modify guards or
covers.
• Lock-out power source before making
adjustments, cleaning, or maintaining
equipment.
• Failure to follow these precautions will
result in serious injury or death.

Chapter 1: Safety Precautions
Confined Space Hazards and Entry Procedures
• Note that the interior of this equipment is considered a con-
fined space. Maintenance of this equipment can require
access to the confined space.
• Access doors must be shut and locked except when access
is required.
• Doors giving access to dangerous equipment must be safety
interlocked.
• The following entry procedures must be followed:
— Be aware of all possible hazards present inside the con-
fined space and wear personal protective equipment
(PPE) as needed.
— Complete a permit to work and follow all permit required
confined space entry procedures defined by the site
manager.
— Make sure that the area has been purged of any hazard-
ous products or gases. Check the atmosphere for harm-
ful gases or vapors with a suitable gas analyzer and
make sure levels are safe before entering.
— Do not smoke or use naked flames.
— Lock out and tag out power supplies and fuel supplies to
all equipment.
— Do not work alone. Work in teams of at least three so
that help is immediately available in the event of an
emergency.
— Confirm that all personnel have safely exited the equip-
ment and tools have been recovered once work is
complete.

Chapter 1: Safety Precautions
Fall Hazard
• Ladders, stairways and platforms are for use by competent
and trained personnel only. Do not allow children or other
unauthorized persons to have access to the equipment.
• Access to the equipment must be restricted by the use of
security fencing and lockable gates.
• Lower sections of ladders must be fitted with a lockable
safety gate to prevent unauthorized access.
• Make sure that hot surfaces have had adequate time to cool
before working on or in the equipment.
• Lock out and tag out power supplies and fuel supplies to all
equipment.
• Do not attach lifting equipment to ladders or platforms.
• Do not go outside of the safety rails provided on elevated
platforms.
• Do not work at heights during high winds, rain, snow, or ice
storms.
ST-0056–1
Prevent Roof Damage Due to Vacuum Pressure
• Roof damage can result from excessive vacuum or internal
pressure from fans or other air moving systems. The manu-
facturer does not warrant this type of roof damage.
• Adequate ventilation or “makeup air” devices must be pro-
vided for all powered air handling systems.
• The manufacturer does not recommend the use of down-
ward flow systems (suction).
• Severe roof damage can result from any blockage of air
passages.
• Operating fans during high humidity or cold weather condi-
tions can cause air exhaust or intake ports to freeze.
