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 reg-
ulated by setting the temperature dial of the adjustable sur-
face mounted thermostat located behind the left tank end
cover.
This thermostat controls the water
heater’s heating element only. (A
separate thermostat should be uti-
lized in monitoring the tempera-
ture from the collector).
To comply with safety regulations
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: 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 122°F (50°C) 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.
