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.
