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-ring” ARE
NOT covered by warranty.
A. Combination Thermostat and High Limit Control
(ECO)
After water and electrical connections have been made and
tank is lled with water, turn on power to the heater. The
heater is now in operation.
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 qualied 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.
