1.13 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 solenoid to the frypot and turn on the
ATO pump. The pump draws oil from the JIB (Jug In Box) to a port in the rear of the frypot. Once
the oil level has satisfied the sensor, the pump and solenoid turn off.
The ATO board is located inside the box, behind the JIB (see Figure 1).
The power for the ATO board is supplied from the transformer box. The
power passes through the transformer inside the ATO box to the board.
