OPERATING YOUR WATER HEATER

Before Using

1.Make sure the water heater has been properly installed. See “Installing Your Water Heater” section.

2.Completely fill the tank with water. (See Figure 2)

3.After the water heater tank is completely filled with water, connect electrical power to the water heater.

4.Read the “Water Temperature Regulation” section of this manual. If the instructions are not clear, contact a qualifi ed person.

5.Adjust the thermostat to the desired temperature setting as described under “Adjusting the Thermostat/ High Limit Control” section.

IMPORTANT: Do not attempt to operate this water heater if the thermostat(s), or surrounding insulation has been exposed to water in any way. Immediately call a qualifi ed person to inspect the water heater and replace any thermostat or insulation that has been exposed to water. Do not attempt to repair these parts. Water heaters subjected to fl ood conditions or any time the thermostat(s) have been submerged in water require replacement of the entire water heater.

Safety Shut-off

This water heater is designed to automatically shut-off in the event that the water temperature exceeds 170°F or 77°C. A high limit control switch is used to shut off the power to the elements if the water temperature exceeds 170°F or 77°C. The high limit control switch can be reset by fi rmly pushing in the red reset button located on the thermostat. Follow the instructions under “Adjusting the Thermostat/High Limit Control”, section to properly reset the high limit control. If the high limit control switch continues to shut-off the water heater contact a qualifi ed person for service.

Water Temperature Regulation

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.

Feel water before bathing or showering.

Temperature limiting valves are available.

The thermostat is adjusted to a temperature setting of 120°F or lower when it is shipped from the factory. Water temperature can be regulated by adjusting the thermostat to the preferred setting as shown in “Adjusting the Thermostat/High Limit Control.” The preferred starting point is 120°F. There is a hot water scald potential if the thermostat is set too high.

IMPORTANT: Adjusting the thermostat past 120°F on the thermostat will increase the risk of scald injury in the times shown below.

NOTE: During low demand periods when hot water is not being used, a lower thermostat setting will reduce energy losses and may satisfy your normal hot water needs. If hot water use is expected to be more than normal, a higher thermostat setting may be required to meet the increased demand.

When leaving your home for extended periods (vacations, etc.) turn the thermostat to its lowest setting. This will maintain the water at low temperatures with minimum energy losses and prevent the tank from freezing during cold weather.
