must be installed on the rear panel of the ice machine.
1. Disassemble the strain relief device into its three
components.
2. Install the cord holder through the opening in the
lower right corner of the rear panel of the ice
machine.

TERMINAL BLOCK WIRE CONNECTION
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 .
