IMPORTANT SAFETY INFORMATION
T
o reduce the risk of property
damage, serious injury or death,
read and follow the precau ons below,
all labels on the water heater, and
the safety messages and instruc ons
throughout this manual.
RISKS DURING INSTALLATION
AND MAINTENANCE
Electric Shock Risk
Contact with the electrical
parts in the junction box and
behind the access doors can
result in severe injury or death from
electrical shock:
 Disconnect power by open-
ing the circuit breaker or
removing the fuses before
installing or servicing.
 Use a non-contact circuit
tester to confirm that power
is off before working on or
near any electrical parts.
 Replace the junction box
cover and access doors after
servicing.
Li ing Risk
WARNING! The
water heater is heavy.
Follow these precau-
 ons to reduce the risk of property
damage, injuries from li ing or impact
injuries from dropping the water
heater.
 Use at least two people to li the
water heater.
 Be sure you both have a good grip
before li ing.
U se an appliance dolly or hand
truck to move the water heater.
Scalding Risk
This water heater can
make water hot
enough to cause
severe burns
instantly, resulting in severe injury or
death.
• Feel water before bathing or
s howering
• To reduce the risk of scalding, install
Thermostatic Mixing Valves (tempera-
ture limiting valves) at each point-
of-use. These valves automatically
mix hot and cold water to limit the
temperature at the tap. Mixing valves
are available from your local plumb-
ing supplier. Follow manufacturer’s
instructions for installation and adjust-
ment of the valves.
• The thermostat(s) on this water
heater have been factory set to
approximately 120°F to reduce the
risk of scalding. Higher tempera-
tures increase the risk of scalding,
but even at 120°F, hot water can
scald. If you choose a higher tem-
perature, Thermostatic Mixing
Valves located at each point-of-use
are particularly important to help
avoid scalding.
Temperature Time to Produce
a Serious Burn
120°F (49°C) More than 5 minutes
125°F (52°C) 1½ to 2 minutes
130°F (54°C) About 30 seconds
135°F (57°C) About 10 seconds
140°F (60°C) Less than 5 seconds
145°F (63°C) Less than 3 seconds
150°F (66°C) About 1½ seconds
155°F (68°C) About 1 second
For informa on about changing the
factory thermostat se ng(s), refer to
the “Adjus ng Temperature” sec on in
this manual (“Step 11” on page 15).
Even if you set the water heater
thermostat(s) to a low se ng, higher
temperatures may occur in certain
circumstances:
In some cases, repeated small draws of
water can cause the hot and cold water
in the tank to “stack” in layers. If this
happens, the water can be as much as
thirty degrees ho er than the thermo-
stat se ng. This temperature varia on
is the result of your usage pa ern and
is not a malfunc on.
Water temperature will be ho er if
someone adjusted the thermostat(s) to
a higher se ng.
Problems with the thermostat(s),
or other malfunc ons may result in
higher than expected water tempera-
tures.
If the water heater is in a hot envi-
ronment, the water in the tank can
become as hot as the surrounding air,
regardless of the thermostat se ng.
If the water supplied to the water
heater is pre-heated (for example, by
fa solar system) the temperature in
the tank may be higher than the water
heater’s thermostat se ng.
To reduce the risk of unusually hot wa-
ter reaching the fi xtures in the house,
install Thermosta c Mixing Valves at
each point-of-use.
If anyone in your home is at par cular
risk of scalding (for example, the elder-
ly, children, or people with disabili es)
or if there is a local code or state law
requiring a certain water temperature
