Hi-Amperage Overload Adjustment

The proper adjustment of Howe's hi-amperage overload device will ensure proper protection for the ice flaker.
To set the overload device correctly, mark the location of the set screw before any adjustment is made. Using
a small flathead screwdriver, gently and slowly turn counter-clockwise (left) until overcurrent LED on the control
board illuminates. Turn screw clockwise (right) one (1) hash mark and stop. Press the reset button to start the
machine again.
The 460V panel has two overload devices. The left device is for the drive motor and the right device is for the
water pump. Both should be adjusted according to the full load amperage rating on their respective motors.
Notice that the range scale is different for each overload device.
