14 • Electric Mini Tank Water Heater
Step 9:
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 on
this water heater has been factory
set to approximately 105°F to reduce the
risk of scald injury. You may wish to set a
higher temperature 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 (page 4).
If you increase the water heater’s tempera-
ture se ng, install Thermosta c Mixing
Valve(s) at each point-of-use to reduce the
risk of scalding.
Figure 19 - Adjust Thermostat Mixing Valves
at each point-of-use to 120°F or lower.
To adjust the water heater’s thermostat:
• Turn the water temperature dial
clockwise () to increase the tem-
perature, or counter clockwise () to
decrease the temperature.
• Check water temperature at several
points of use in your home (for exam-
ple, bathtub faucet, shower, or lava-
tory 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.
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.
