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. 
1
Set the thermostat(s) to 
desired temperature. The 
thermostat(s) on this water 
heater have 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:
• 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 and lower access 
panels and fold away the insula on. 
• Turn the water temperature dial 
clockwise ( >>) to increase the tem-
perature, or counter clockwise ( << ) 
to decrease the temperature. Adjust 
both thermostats to the same tem-
perature se  ng. To avoid a shortage 
of usable hot water, do not adjust 
the upper thermostat to a tempera-
ture se  ng that is higher than the 
lower thermostat’s temperature 
se ng. 
NOTE: Most models have two thermo-
stats, but some models may only have 
one. If your water heater has only one 
thermostat, it is located behind the 
lower access panel.
• Fold the insula on back in place and 
replace the access panels. 
WARNING! Be sure panels are 
secured to reduce the risk of fi re and 
electric shock.

Turn the electric power back 
on. 
3
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.
