the water heater, perform the
1. Make sure the water heater has been properly
2. Completely fill the tank with water. (See Figure 2)
3. Apply power to the water heater only after the tank
is completely filled with water.
4. Carefully read and understand the "Water
Regulation" section of this manual.
5. Adjust the thermostat to the desired temperature
setting as directed under "Adjusting the Thermostat/
High Limit Control".
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 qualified
service technician 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 flood conditions or any time the thermostat(s)
have been submerged in water require replacement of
the entire water heater.
This water heater is designed to automatically shut-off
in the event that the water temperature exceeds 170°F
(77°C). A high limit control switch is used to shut off the
power to the elements if the water temperature exceeds
170°F (77°C). The high limit control can be reset by
firmly pushing in the red reset button located on the
thermostat. Follow the instructions under "Adjusting the
Thermostat/High Limit Control" to properly reset the high

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
limit Control." The preferred
point is 120°F. There is a hot water scald
if the thermostat
is set too high.
Adjusting the thermostat past 120°F on the
thermostat 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 1-1!2 seconds
160°F (71°C) at less than 1 second
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
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.
