1.10 ATO (Automatic Top-off) Service Procedures

The automatic top-off system is activated when the oil level falls below a sensor in the rear of the frypot. The signal is sent to the ATO board to engage the return actuator to the frypot and turn on the ATO pump. The pump draws oil from the JIB (Jug In Box) through the rear return manifold into the rear of the frypot. Once the oil level has satisfied the sensor, the pump turns off and the actuator closes.

The ATO board is located inside the box, behind the JIB (see Figure 1). The power for the ATO board is supplied from the right hand component box. The power passes through the transformer inside the ATO box to the board.

board is fully locked into connector.

B.Ensure fuse below right control box is not blown and fuse on the right side of ATO box is not blown.

C.Check that proper voltage is present at transformer. See table in section 1.10.2.

A. Ensure the yellow LED is securely attached to plug J6 on the ATO board.

B. Ensure power is present in the component box.

C.If power is present in component box, check the transformer for correct voltage.

A.Ensure all wiring harnesses are securely connected to ATO board and solenoids.

B.Check return actuator to ensure actuator is functional.
