Safety Guidelines for Portable Dryers
Safety guidelines are general-to-specific rules that promote safe practices in the grain drying environment
and which must be respected at all times. Save these safety guidelines for future reference.
Make sure to read these safety guidelines carefully prior to installing, operating, or
CAUTION
Operation
• Read and fully understand this user guide before attempting to operate the grain dryer.
servicing your grain dryer.
• Never operate the grain dryer with its safety guards removed.
• Never operate the grain dryer by bypassing any safety device.
• Never exceed the maximum recommended drying temperature.
• Do not operate the grain dryer in an area where combustible material might be drawn into the fan.
• The operating and safety recommendations in this guide pertain to common cereal grains, as indicated. When drying other types of grain or products, contact the GSI Group, LLC for additional
recommendations.
Servicing
• The power supply must be disconnected when servicing electrical components. Always use
extreme caution when measuring voltage or performing procedures that require the dryer to be
turned on.
• Before attempting to remove and reinstall a fan’s propeller, make sure to read the recommended
procedure. If you are unsure about performing this procedure or cannot locate it, contact the GSI
Group, LLC before proceeding.
Cleanliness
• Keep the grain dryer clean at all times.
• Do not allow fine material to accumulate in the plenum chamber.
PNEG-1891 Portable Dryers

Chapter 1: Safety Precautions
• An unclean plenum increases resistance to airflow, increases drying time, reduces drying efficiency,
and creates a fire hazard.
• Always keep the area around the fan’s air inlet clear of any obstacles and combustible material.
Augers/Auxiliary Conveyors
Always use extreme caution when working around augers and auxiliary conveyors
CAUTION
• Always keep auger drive belts adequately tensioned to prevent slippage.
• Make sure that the technical specifications and capacities of the auxiliary conveyors are matched to
those of the dryer augers.
because they can start automatically.
Burners/Gas Lines
• Regularly check for leaks at all gas line connections. If any leaks are detected, do not operate the
grain dryer. Shut off the main power and repair the leaks before operating. Gas lines must be
replaced regularly as required by the local gas regulations for your area.
• Routinely check for potential gas plumbing leaks. Check the liquid propane vaporizer for contact
with the burner vanes.
• Never use an open flame to locate gas leaks. Pour a solution of soap and water over the gas pipe
joints and connections, and check for the appearance of small bubbles.
• Set the pressure regulator to avoid applying excessive gas pressure to the burner during ignition or
when the burner is on.
• Do not use flammable or combustible materials in the dryer’s vicinity because explosive vapors can
be drawn into the fan and ignite.
• Always use extreme caution when working around high-speed fans and gas burners because they
can start automatically.

▪ Installing a Leg Stand to the Dryer Basket Corner
▪ Installing a Leg Stand Along the Dryer Frame
▪ Installing the Leg Stands Behind the Hitch Frame
Guidelines for Supporting the Dryer with Concrete Blocks
Before filling the dryer with grain, the dryer frame must be supported with either concrete blocks or leg
stands. If choosing concrete blocks, follow these guidelines for proper installation:
• Place a 2 x 6 or 2 x 8 board between the dryer frame and the concrete blocks to prevent the dryer
frame from fracturing the concrete blocks.
• To prevent the dryer from overturning, it must be secured to the foundation using cables and turnbuckles that are fastened to anchors in the concrete foundation.
• Do not use the wheels as supports. Wheels are for transporting the dryer when it is empty.
• Place concrete blocks six feet apart on each side of the dryer to support the dryer frame.
NOTE: A minimum of one support for every six feet of basket length is required on each side.
• The blocks must be able to support the weight of a dryer that is filled with grain.
• With the hitch tongue removed, place a concrete block under the hitch mount location.
• The hitch assembly and the fan support must remain in place during operation. The hitch assembly
and fan support are not part of the transport tie down assembly.
• Use shims to provide uniform, level support for all blocks.
• The dryer should be 16 in. (40.6 cm) off the concrete pad to accommodate for clean-out and the use
of auxiliary grain handling equipment.
