3.6. Grain Cooling System (optional)
Overview
• An optional grain cooling system with either one or two cooling floors can be supplied with the dryer. Each
of the cooling floors has door openings spaced evenly along the length of the dryer. The operator has
several grain cooling options from which to choose.
• The cooling floor(s) work in combination with a manually positioned cooling flap that can direct a portion of
the blower system airflow. The cooling flap is in-line with the position of the exterior handle so that the
operator can tell at a glance where the cooling flap is positioned. The handle position should be secured
with the locking system.
• The cooling flap position determines the amount of cooling air that reaches the grain. Moving the handle
down lowers the cooling flap and increases the cooling. To decrease the cooling, move the handle up. To
shut off the cooling move the handle all the way up.
