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.
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.
