Before Using
1, Make sure the water heater has been properly installed. See "Installing Your Water Heater" section.
2, Make sure the air filter is correctly seated, as it may shift during shipping or installation. See "Repair Parts Illustration" section.
3, Completely fill the tank with water (See "Water Piping" section).
4, After the water heater tank is completely filled with water, connect electrical power to the water heater.

IMPORTANT: Do not attempt to operate this water heater if the unit has been submerged, subjected to flooding, or surrounding insulation has been exposed to water in any way.
Do not attempt to repair a unit subjected to flood conditions. Water heaters subjected to flood conditions or any time the unit has been submerged in water require replacement of the entire water heater.

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which wilt satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally 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 water heater. 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 see Temperature Settings table at right.
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.
The water heater is adjusted to a temperature setting of no higher than 120°F when it is shipped from the factory. Water temperature can be regulated by adjusting the User Interface Module to the preferred setting as shown in "Adjusting the User Interface Module/Operational Mode" The preferred starting point is 120°F. There is a hot water scald potential if the temperature set point is set too high.
IMPORTANT: Adjusting the set point above 120°F on the User Interface Module will increase the risk of scald injury in the times shown below.

Adjusting the User Interface Module/
Operational Modes
The water temperature setting can be adjusted from 95°F to
150°F. Use the Up and Down Buttons _ on the front panel to set the desired temperature.
NOTE: The temperatures displayed on the User Interface are approximates. The actual temperature of the heated water may vary.
IMPORTANT: Before attempting to adjust the thermostat, read the "Water Temperature Regulation" section. If the instructions are not clear, contact a qualified person.
