On machines equipped with Electric Blower-Dryer option, some were equipped with a lighted BLOWER ON / OFF switch which controls power to the Blower-Dryer (Fig. 9-b) and indicates when the Blower- Dryer is running. NOTE: A RED light (Fig. 9-b) is provided on Blower-Dryers equipped with electric heat to alert the operator to TURN MACHINE OFF, DISCONNECT ELECTRIC POWER, AND HAVE UNIT SERVICED BY A QUALIFIED TECHNICIAN if the blower over-temperature thermostat has been activated.

On machines equipped with Steam Blower-Dryer option, some were equipped with a lighted BLOWER ON switch which controls power to the Blower-Dryer (Fig. 9-c) and indicates when the Blower-Dryer is running. When the combination Blower-Dryer switch and indicator light is not provided, the steam Blower-Dryer is on when the pumps are on.

Push the green START switch at either end of the machine or at the control box — to start the conveyor and pumps. Push the red STOP switch at either end of the machine or at the control box to stop the conveyor and pumps. Tanks will continue to heat if the POWER ON / OFF switch remains ON. If a separate switch is provided for a Blower-Dryer, push once for On and a second time for OFF. If no separate Blower-Dryer switch is present, the Blower-Dryer should be ON when the pumps are on.

DISHWASHING

To start the conveyor, pumps, and blower-dryer (if not switched separately), press the green START switch at either end of the machine or at the control box. The conveyor will operate only when all machine doors are closed and the tanks are filled to the proper level. When equipped with Blower- Dryer, the Blower-Dryer will operate with the conveyor and pumps. Press the red STOP switch at either end of the machine or at the control box to stop the conveyor and pumps. The Auto-Timer will automatically stop the machine if no ware is washed for a preset length of time. The Auto-Timer shut- off setting can be changed by your Hobart service technician (range is 2 – 8 minutes).
