Table 4 - Installation Checklist

Part 6 - Operation

Tank must be full of water before the power is turned on. Heating
elements will be damaged if energized for even a short time while
tank is dry. Failures due to "dry-firing" ARE NOT covered by warranty.
After water and electrical connections have been made and tank is
filled with water, turn on power to the heater. The heater is now in
operation.
A. Combination Thermostat and High Limit Control (ECO)
Each water heater is equipped with a combination Thermostat -
High Limit Control (ECO). Thermostats are located above the heating
elements. If for any reason the water temperature becomes excessively
high, the ECO breaks the circuit to the heating element. Once the
switch opens it must be reset manually. However, THE CAUSE OF THE
OVER TEMPERATURE CONDITION MUST BE CORRECTED FIRST.
The cause of the high temperature condition must be investigated
by a qualified service technician and corrective action must be taken
BEFORE placing the water heater back in service. Failure to do so
could result in property damage, severe personal injury, or death.
B. Thermostat Adjustment and ECO Reset
There are two thermostats on dual element heaters. If temperature
adjustment is necessary, TURN OFF POWER TO HEATER, remove black
access cover and insulation. The thermostat protective cover SHOULD
NOT be removed. Set temperature indicator to desired temperature.
