OPERATION
TEMPERATURE REGULATION
WARNING
HOTTER WATER CAN SCALD: Water heating tanks are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can cause scalds resulting in serious personal injury and/or death. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirmed, or physically handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of tempering device, such as a mixing valve, should be used at the hot water taps used by these people or at the tank. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting of the thermostat, read the Temperature Adjustment section.
WARNING
KEEPING THE THERMOSTAT SETTINGAT 120°F WILL REDUCE THE RISK OF SCALDS. Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.
TEMPERATURE SETTINGS
NOTE: Residential water heating tanks will not supply sanitizing hot water for dishwashers.
The thermostat is factory set at approximately 120°F (Hot) and is adjustable if a different water temperature is desired. Read all warnings in this manual and on the tank before proceeding.

TEMPERATURE ADJUSTMENT
To adjust the temperature setting:
1.Turn “OFF” the electrical power to the water heater, at the junction box.
WARNING
HAZARD OF ELECTRICAL SHOCK! Failure to turn “OFF” electric power to the tank will result in the possibility of DEATH, SERIOUS BODILY INJURY OR PROPERTY DAMAGE.
2.Take “OFF” the access panel and fold away the insulation.
3.Turn the water temperature dial clockwise ( 
) to increase the temperature, or counterclockwise ( 
) to decrease the temperature.
4.Fold the insulation back in place and replace the access panel.
5.Turn “ON” the power supply.
