The risk of scald injury increases as you increase water temperature. A lower setting is more economical and
reduces the risk of scalding. Use a water tempering or mixing valve and extreme caution when using hot water
to avoid scald injury. Consult codes for conformance. Failure to follow the instructions in this warning statement
could result in serious personal injury or death from scalds.
Be sure to disconnect electrical power before performing service. Failure to do so could result in electrical shock,
property damage, serious personal injury, or death.
If draining of the water heater is necessary, open the T&P valve or a hot water tap to prevent vacuum buildup
in the tank and piping.
A. Resetting the High Limit Switch
Occasionally, the high temperature limit shut off device may trip
the reset. This occurs when water temperature exceeds 190
shut-off device may also trigger due to a power outage or electrical
storm.
To reach the thermostat:
• Disconnect the power cord (or shut off the circuit breaker - 8
Model) and remove the front cover.
• Firmly press the reset button with the tip of a ball point pen or
similar object. See Figure 8, B.
A click indicates the reset was tripped.
• Reconnect the power.
• Check the operation of the thermostat. See the following section.
Call a technician if the high limit needs to be reset frequently.
B. Checking Thermostat Operation
To check thermostat operation:
• Turn the temperature dial from high to low. If the red light does not turn off on the low setting, turn off the
power supply and call a qualifi ed service technician to replace the thermostat.
• If the red light does go off , the thermostat is working properly.
• Turn the dial to the desired setting. NOTE: A lower setting is more economical and reduces the risk of
scalding.
• Replace the cover plate.
NOTE: After adjusting the water temperature at the thermostat, allow the water heater enough time to heat
the water to temperature. After the water heater has stopped heating, use a thermometer to measure the water
temperature at a hot water outlet in the structure.
C. Changing the Heating Element
• Turn off the power supply and drain the water heater (see procedure, this manual).
• Remove heating element (see procedure, this manual).
• Install new element with gasket, making sure the gasket and element are positioned correctly. Tighten the
retaining nuts and wire connections.
• Ensure the thermostat temperature sensor is inserted into the well located on the element assembly and
secured with a black rubber grommet.
• Refi ll the tank with water before restoring power.
D. Changing the Thermostat
• Turn off the power supply.
• Disconnect the two (2) wire connectors on the thermostat.
• Loosen the two (2) brass screws on the right side of the thermostat and pull the wires out.
• Unscrew and remove the two (2) Phillips screws holding the thermostat onto the tank.
• Install the new thermostat and re-attach the wiring and screws.
• Ensure the thermostat temperature sensor is inserted into the well located on the element assembly and
secured with black rubber grommet.
