For the Electrician

Electrical Connections:

Check the ice machine nameplate (located on the back panel) for the voltage requirements, and minimum circuit ampacity. The ice machine requires a solid chassis to earth ground.

Connect the ice machine to its own electrical circuit so it is individually fused. Voltage variation must remain within the limitations, even under starting conditions.

Note: All external wiring must conform to national, state and local electrical codes. The use of a licensed electrician is required to perform the electrical installation.
