• To enable pre-season mode, click System→Control (Advanced)→Board Mode and then select
Pre-season Mode.
• Place the dryer in normal mode once inspections have been completed and you are ready to dry
grain.
IMPORTANT: If you power off the dryer while in pre-season mode, normal mode is automatically
enabled the next time you power on the dryer. Make sure to reselect pre-season
mode if further tests are required.
Cleanliness
• Keep the grain dryer clean at all times.
• Do not allow fine material to accumulate in the plenum chamber.
• 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
CAUTION
Always use extreme caution when working around augers and auxiliary conveyors
because they can start automatically.
• 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.
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.
