5.After the tank is completely filled with water, turn on power to the water heater. Note: The water heater performs
Important: Operation of this water heater without access doors or insulation could result in much higher water temperatures than the desired set point, increasing the risk of scald injury. Do not operate water heater with the access doors or insulation removed.
Access Doors
Important: Do not attempt to operate this water heater if the temperature sensor(s), electronic control board, or surrounding insulation has been exposed to water in any way. Immediately call a qualified service technician to inspect the water heater and replace any temperature sensor(s), electronic control board, or insulation that has been exposed to water. Do not attempt to repair these parts. Water heaters subjected to flood conditions or any time the temperature sensor(s) or electronic control board have been submerged in water require replacement of the entire water heater.
Safety Shut-off
This water heater is equipped with a high limit control switch that is designed to shut off the power to the elements if the water temperature exceeds170°F (77°C). Use the diagnostic control chart on page 14 to help determine the cause of the high limit

WARNING
Water temperature over 125°F can cause severe burns instantly or death from scalds.
Children, disabled, and elderly are at highest risk of being scalded.
See the instruction manual before setting temperature at water heater.
Feel water before bathing or showering.
Temperature limiting valves are recommended.
The temperature control is adjusted to a setting of 120°F or lower when it is shipped from the factory. Water temperature can be regulated by adjusting the temperature control system to the preferred setting as shown in "Operating the Temperature Control System."
The recommended starting point is 120°F. There is a hot water scald potential if the temperature control is set too high.
Important: Adjusting the temperature past 120°F on the temperature control will increase the risk of scald injury. Hot water can produce first degree burns within:
120°F (49°C) more than 5 minutes
130°F (54°C) at 20 seconds
140°F (60°C) at 3 seconds
150°F (66°C) at
