WARNING

Always disconnect power to the ice machine before working on electrical circuitry.

After the electrical cord is installed in the strain relief device, the cord must be connected to the terminal block to supply power to the ice machine.

1.Remove two Phillips head screws to remove the lower panel from the front of the ice machine.

2.Carefully reach into the ice machine and pull the electrical cord forward to the terminal block.

3.Strip away enough insulation from the electrical cord to allow for good electrical connections at the terminal block .
