INSTALLATION
Replace the junc on box
cover and secure with the
screws provided.
WARNING! Be sure cover is secured
to reduce the risk of fi re and electric
shock.
Adjus ng the
Temperature
With the installa on steps completed,
you may adjust the water heater’s
temperature se ng if desired.
WARNING! Be sure panels are
secured to reduce the risk of fi re and
electric shock.
1
Turn the electric power back
on.
2
Set the thermostat to desired
temperature. The thermostat
on this water heater has been
factory set to approximately 120°F to
reduce the risk of scald injury. You may
wish to set a higher temperature to
provide hot water for automa c
dishwashers or laundry machines, to
provide more hot water capacity, and
to reduce bacterial growth. Higher
tank temperatures (140° F) kill bacteria
that cause a condi on known as
“smelly water” and can reduce the
levels of bacteria that cause water-
borne diseases.
WARNING! Higher temperatures
increase the risk of scalding, but even at
120°F, hot water can scald (see page 4).
If you increase the water heater’s tem-
perature se ng, install Thermosta c
Mixing Valve(s) at each point-of-use to
reduce the risk of scalding.
To adjust the water heater’s thermo-
stat:
• Water temperature should be pri-
marily adjusted from the ESM (see
page 17).
• To adjust water temperature from
the ET (see steps referring to il-
lustra ons on page 18). Be sure the
electrical power to the water heater
is turned OFF at the circuit breaker
panel (or remove the circuit’s fuses).
WARNING! Working near an
energized circuit can result in severe
injury or death from electrical shock.
Check wires with a circuit tester to
make sure power is off .
• Remove the upper access panel/ESM
and fold away the insula on.
• Turn the water temperature set point
knob clockwise ( >>) to increase the
temperature, or counter clockwise
( << ) to decrease the temperature.
• Fold the insula on back in place and
replace the access panel.

Wait for the water to heat up.
It may take several hours for a
tank of cold water to heat up.
If you have no hot water a er two
hours, refer to the Troubleshoo ng
Sec on (see page 24).
WARNING! If you have increased
the temperature se ng and the
Thermosta c Mixing Valves are not set
properly (or not installed) you could
scald yourself while checking the
temperature.
4
Check water temperature at
several points of use in your
home (for example, bathtub
faucet, shower, or lavatory sink) and
adjust the Thermosta c Mixing Valves
as needed. If you aren’t sure how to
adjust the Thermosta c Mixing Valve
se ngs, or aren’t sure if you have
Thermosta c Mixing Valves, contact a
qualifi ed person.
Step 10:

Adjust Thermosta c Mixing Valves at each point-
of-use to 120°F or lower.
