Grounding Instructions

This appliance must be connected to a grounded wiring system. If it should malfunction or break down, grounding provides a safe path of least resistance for electrical current, reducing the risk of electrical shock. The cord for this appliance has an equipment-grounding conductor and a grounding plug. It must only be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Diagram Description: An illustration shows a grounded outlet with a grounding pin and a plug with a grounding pin, indicating proper connection.

Important Information

To reduce the risk of a leaking condition, do not store where freezing may occur. Damage to internal components may result.
