Grounding Instructions

This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for
electric current to reduce the risk of electrical shock. This product is equipped with a cord having an equipment-grounding
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.

Extension Cords

Use only 3-wire extension cords that have 3 prong grounding-type plugs and 3-pole cord connectors that accept the plug
from the product. Use only extension cords that are intended for outdoor use. These extension cords are identified by a
marking “Acceptable for use with outdoor appliances; store indoors while not in use.” Use only extension cords having an
electrical rating not less than the rating of the product. Do not abuse extension cord and do not yank on any cord to
disconnect. Keep cord away from heat and sharp edges. Always disconnect the extension cord from the receptacle
before disconnecting the product from the extension cord.

Warning - To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch plug with wet
hands.
