Condensation does not mean your tank is leaking. Most of reported tank leaks on installation are proven to be
condensation. To avoid unnecessary inconvenience and expense, make sure the tank is leaking before calling an
independent servicing contractor or qualified service professional.
If the water heater is to remain idle for 30 days or more or is subjected to freezing temperatures while shut off, the water
heater and piping should be fully drained and the drain valve should be left fully open. Refer to the “General Operation”
section of this Installation and Operating Instructions Manual for the procedure on draining the water heater.
WARNING
If the water heater display does not show “Operational” in the “Status” indicator, there may be an operating
malfunction with the water heater. If this is the case, a numeric code will be displayed. Refer to the label next to
the display for the definition of the error code and call your plumbing professional or service agent to service the
water heater. Do not try to reset the water heater without having a qualified service person to diagnose and correct
the problem. If the display is blank or does not show an error code, make sure there is power to the water heater.
Setting the water temperature to the maximum set point can result in scalding hot water delivered to the faucets. It
is highly recommended that the maximum setpoint be adjusted to the lowest temperature possible for the needs of
the installation. See following section to change the maximum setpoint limit (max setpoint). Make sure the water
heater control display is not in a public area that can result in the temperature settings being improperly adjusted.
See previous warning on scalds and an ASSE approved mixing valve.
NOTICE
When the maximum setpoint is reached, the display will show “Max Setpoint” without the setpoint value. The
maximum setting is equal to approximately 180˚F (82˚C).
The default temperature setpoint from the factory is 70˚F (21˚C).
