QUICK START UP PROCEDURE

STARTING THE DRYER

This start up procedure is for a cold start on wet grain for continuous flow operation.

1.Set the MAXON or FAST ACTION HAND VALVE on the incoming fuel line to the ON position.

2.Make sure the MOISTURE CONTROL switch is in the OFF position.

3.Turn the FAN switch (or switches if a multi-fan dryer) to the ON posi- tion. The light in the switch should light when the fan comes up to about half speed.

4.Adjust the PLENUM AIR PRESSURE switch if necessary. Use a flat blade screwdriver counterclockwise to make it more sensitive (taking less pressure to activate it), or clockwise for the opposite effect.

5.Turn the HEATER switch (or switches if a multi-fan dryer) to the ON position. The heater will purge for about 10 seconds then ignite. The light in the heater switch will come on during ignition and will stay on if the heater ignites. If the heater does not ignite, the light will go out after trial for ignition and the dryer will shut down, indicating that it did not light. If this happens check gas supply, and all valves in the fuel line to make sure they are on.

ADJUSTING THE TEMPERATURE

1.Set the HIGH-LOW FIRE PLENUM THERMOSTAT on the left side of the dryer to the drying temperature that you want to run (180° to 200°). On multiple module dryers set the plenum chambers 30° to 60° apart.

Hottest at the top, most cool at the bottom.

2.On LP gas models adjust the PRESSURE REGULATOR (high fire) on the burner fuel line, so that burner will reach the thermostat setting andswitch to (low fire) (pressures may be required up to 25 lbs.). Natu- ral gas does not have a regulator, but uses a LARGE BALL VALVE close to the vertical supply line for adjustment (pressures may be re- quired up to 18 lbs.).

On LP gas models adjust the small RED HANDLED BALL VALVE (low fire) so that the burner maintains flame then switches back to (high fire). Natural gas has a BALL VALVE close to the burner control box, for low fire adjustment.

3.Adjust the burner pressure so that the burners cycles 4 times per minute (approx. 10 sec. on high--approx. 5 sec. on low). When on high fire increasing the pressure with the PRESSURE REGULATOR DECREASES the time spent on high fire. When on low fire increasing the low fire pressure with the RED BALL VALVE INCREASES the time spent on low fire.

4.On LP gas models adjust the VAPORIZER so the fuel pipes going to
