STAGED BATCH CHECK
To check the staged batch opera- tion, turn the control power switch to the on position. Turn the drying mode switch to the staged batch posi- tion. Press the reset button, open the main fuel supply valve at the tank on an LP dryer, or valve in the fuel supply line on a natural gas dryer.
Turn on the electric shut off valve to allow fuel flow to the dryer, if so equipped. Turn the load switch to auto and unload switch to one speed. Push the dryer power start button, and the controller will se- quentially start all dryer components in their proper order. If any switches are not in their correct position for staged batch operation, the dryer will indicate improper switch position, and will not start until the switches are in the proper position. After start- ing, all batch timers will time down in sequence. When the unload cycle is complete the timers will automati- cally reset to their original settings, and start the dry timer again.
DRYER SHUTDOWN
To shut down the dryer, first close the fuel supply valve at the tank or valve along the fuel line. If the burner is operating, let the dryer run out of fuel, and it will shut down automatically due to loss of flame. Close the fuel valve at the dryer, and press the dryer power stop button. Turn off the safety discon- nect handle on the front of the power box, and turn off the main power to the dryer.
EMERGENCY
In case of emergency push the dryer power stop button. The fan, burner and all augers will stop immediately.
