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. Replace insulation and the black access cover. Turn on
power to the heater.

hotter. Turning the knob to
the left (counterclockwise)
makes the water cooler.
Step #5 - Replace the
insulation.
Step #6 - Reattach the access
cover with the two screws.
Step #7 - Restore power by
replacing the fuse or turning
on the circuit breaker.
Step #8 -
a. After resetting the ECO,
ensure the water heater is
operating properly before
leaving the installation.
b. After adjusting the water
temperature, allow the water
heater enough time to heat
the water to temperature.
After the water heater has
stopped heating, measure
the water temperature at
a hot water outlet in the
structure.
Step #9 - If the water heater
is operating properly and
the water temperature is
satisfactory, adjustment is complete.
Risk of scald injury increases as you increase water temperature.
Failure to replace insulation or access cover could result in property
damage, severe personal injury, or death.
