Use and Care Manual

3
The chart shown above may be used as a guide
in determining the proper water temperature for your
home.
!
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F (49°C) or lower
thermostat setting to prevent contact with “HOT” water.
The temperature of the water in the heater is
regulated by the electronic control and surface
mounted temperature sensors.
DO NOT attempt to set the temperature by
removing the electronic control or lower access
panel. See the electronic control operation section
of this manual.
!
DANGER: Hotter water increases the potential for
Hot Water SCALDS.
NOTICE: When used in demand response applications
a thermostatic mixing valve conforming to ASSE
1017 shall be installed on the hot water supply line
following all manufacturer installation instructions.
See page 20 for additional installation information.
IMPORTANT SAFETY INFORMATION.
READ ALL INSTRUCTIONS BEFORE USING.
DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the
water temperature setting of water heater’s thermostat. Water temperatures
above 125°F (52°C) can cause severe burns or death from scalding. Be sure to read
and follow the warnings outlined on the label pictured below. This label is also
located on the water heater near the thermostat access panel.
NOTICE: Mixing valves are recommended for reducing
point of use water temperature by mixing hot and
cold water in branch water lines. It is recommended
that a mixing valve complying with the Standard for
Temperature Actuated Mixing Valves for Hot Water
Distribution Systems, ASSE 1017 be installed. See page
13 for more details and contact a licensed plumber or the
local plumbing authority for further information.
