This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for

conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
DANGER - Improper connection of the equipment; grounding conductor can result in a risk of electrocution. Check with a
qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not modify
the plug provided with the product. If it will not fit the outlet, have a proper outlet installed by a qualified electrician. Do not
use any type adapter with this product.
GROUND FAULT CIRCUIT INTERRUPTER PROTECTION
This water heater is provided with a ground fault circuit interrupter (GFCI) built into the plug of the power supply cord. This
device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become
necessary, use only identical replacement parts that include GFCI protection.

from the product. Use only extension cords that are intended for outdoor use. These extension cords are identified by a

before disconnecting the product from the extension cord.
