Table 5 - Troubleshooting
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.
Occasionally, the high temperature limit shut off device may trip the resets. This occurs when water temperature
exceeds 185
o
F / 85

C. As with all electrical appliances, it is crucial to first shut off all power to the unit directly at
the fuse or breaker box before attempting to reset this water heater. Ensure that all breakers are shut off.
Failure to disconnect the power from the water heater before attempting to install or repair it will result in
property damage, severe personal injury, or death.
A. Resetting the High Limit Switch
Locate the reset button locations as shown below and press both down. If the buttons “click” the unit has reset.
After the unit has reset, turn the breakers back on and observe unit operation.
Call a technician if the high limit needs to be reset frequently.
