DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with small
children, disabled, or
elderly persons may require
a 120°F or lower thermostat
setting to prevent contact
with HOT water.
Water Temperature Set Point
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heater’s
thermostat(s). The lower the temperature
setting, the greater the savings in energy
and operating costs.
Water temperatures above 125°F can
cause severe burns or death from scalding.
Be sure to read and follow the warnings
outlined in this manual and on the label
on the water heater. This label is located
on the water heater above the lower access
panel.
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 3 for more
details and contact a licensed plumber or
the local plumbing authority for further
information.
The electronic control allows the water
temperature to be set from 110°F to 150°F.
The Performance Platinum residential
electric water heater incorporates a
VACATION mode. This sets the
temperature setting to a predetermined
lower thermostat setting.
The chart below may be used as a guide in
determining the proper water temperature
for your home.
Refer to "Programming the Electronic
Control Instructions" on page 14.
