The chart shown above may be used as a guide
in determining the proper water temperature for your home.
!
DANGER: Households with small children, disabled,
or elderly persons may require a 120°F or lower thermostat
setting to prevent contact with “HOT” water.
NOTICE: Mixing valves should be installed to reduce the
point of use water temperature by mixing hot and cold water
in branch water lines. Contact a licensed installer or the local
plumbing authority for further information.
The temperature of the water in the water heater can be regu-
lated by setting the temperature dial of the adjustable surface
mounted thermostat located behind the jacket access panel.
This thermostat controls the
water heater’s heating ele-
ment only. (A separate ther-
mostat should be utilized in
monitoring the temperature
from the collector).
To comply with safety reg-
ulations the thermostat is
factory set at 120° F or less
where local codes require.
!
DANGER: Hotter water increases the potential for Hot
Water SCALDS.

DANGER!
WATER TEMPERATURE SETTING
Safety and energy conservation are factors to be considered when selecting the water
temperature setting of water heater’s thermostat. Water temperatures above 125°F
can cause severe burns or death from scalding. Be sure to read and follow the warnings
outlined on the label pictured below.
!
DANGER: Burns from Hot Water and
Steam - Use extreme care when opening relief
valves, charging closed loop, and filling storage
tank.
The electrical element booster thermostat has
been factory set at 50°C (120°F) to reduce the
risk of scald injury. Adjusting the thermostat to a
higher setting is not recommended. Hotter water
increases the potential for Hot Water Scalds.
