SAFETY ALERT DECALS Three decals displayed on all Airstream Dryers. Belt drives, chain driven meter rolls and combustible fuels must be treated with caution.
SAFETY PRECAUTIONS 1. Read and understand the operating manual before trying to operate the dryer, fan or heater. 2. Never operate a dryer while the guards are removed. 3. Power supply should be OFF for service of electrical components components. Use CAUTION in checking voltage or other procedures requiring power to be ON. USE CAUTION IN THE OPERATION OF THIS EQUIPMENT The design and manufacture of a dryer is directed toward operator safety.

TROUBLE ANALYSIS FOR ALL PORTABLE DRYERS Problem Possible Cause Display shows "BURNER 1 OR 2 VAPOR HIGH TEMPERATURE" message.* The LP gas vapor temperature sensor located in the gas train downstream from the vaporizor has opened, indicating that the vaporizer is running too hot and must be readjusted. (This control is a 200°F limit which automatically resets when it cools). Display shows "BURNER 1 OR 2 WARNING FLAME NOT DETECTED" message.
TROUBLE ANALYSIS FOR ALL PORTABLE DRYERS Problem Possible Cause Display shows "FAN 1 OR 2 FAILURE-NO AIRFLOW" message.* The air switch contacts have opened, indicating the fan may not be turning. The air switch may need adjustment. Display shows "FAN 1 OR 2 CANNOT START-CHECK AIR SWITCH" message.* The air switch contacts have closed prior to the fan starting, indicating a freewheeling blade or improper setting of air switch. Fan motor will not start. 1.
TROUBLE ANALYSIS FOR ALL PORTABLE DRYERS Problem Possible Cause Grain not moving through columns. 1. Check the dryer for fine material buildup inside the columns. 2. Avoid leaving the dryer columns full for long periods at a time (2-3 days) while not operating the dryer or during rainy weather. 3. Empty the dryer. Keep the dryer clean! Do not allow fine material to gather in the plenum chamber. 4. It may be necessary to open the strike off plates in the affected columns in half inch intervals.
TROUBLE ANALYSIS FOR ALL PORTABLE DRYERS Problem Possible Cause Burner operates-But will not cycle from hi-fire to lo-fire. 1. Check the gas pressure reading on the gauge. Problem may be due to insufficient gas regulator setting. Temporarily decrease the hi-lo fire thermostat setting to verify that the thermostat will function and cause the burner to cycle. If burner will cycle at the reduced thermostat setting, it indicates that the problem was due to insufficient heat to satisfy the original setting.
