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
For informa on about changing the
factory thermostat se ng(s), refer to
the “Adjus ng Temperature” sec on in
this manual (“Step 10” 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
a 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
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
SAFETY
RISKS DURING OPERATION
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 shower-
ing.
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 tem-
perature at the tap. Mixing valves
are available from Lowe’s®. Follow
manufacturer’s instructions for instal-
lation and adjustment 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 temperatures
increase the risk of scalding, but
even at 120°F, hot water can scald.
If you choose a higher temperature,
Thermostatic Mixing Valves located
at each point-of-use are particularly
important to help avoid scalding.
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.
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.
