FEATURES
• Meets the thermal efficiency and or
standby loss requirements of the U.S.
Department of Energy and current edition
of ASHRAE/IES 90.1.
ADVANCED ELECTRONIC
CONTROL
• Plain English text and animated icons
display detailed operational and diagnostic
information. Fault or Alert messages
appear if an operational issue occurs.
• Immersion temperature control adjustable
through a range of 90°F to 190°F.
ECONOMY MODE OPERATION
• Control system automatically lowers the
Operating Set Point by a programmed
value during user-defined time periods.
Helps reduce operating costs during
unoccupied or off - peak demand periods.
LINEAR SEQUENCING
• Banks of heating elements (3 elements
per bank) are energized according to
adjustable (1 to 20°F) differential set points
for each bank. First bank on is the last
bank off. Helps reduce current surge and
provides accurate water temperature
control.
GOLDENROD ELEMENTS
• All ITCE31 models ship standard with
patented Goldenrod 24K gold plated
elements. Goldenrod elements provide
long life with superior scaling resistance.
GLASS-LINED TANK
• Three sizes; 50, 80 and 119 gallon
capacity. Tank interior is coated with glass
specially developed by American for water
heater use. Foam insulation reduces costly
heat loss. ASME (optional) maximum
working pressure is 160 psi.
POWER CIRCUIT FUSING
• Protects elements and contactors
from short circuits, overloading or line
surges. Meets National Electric Code
requirements (fusing required when
current draw exceeds 48 amps).
STANDARD VOLTAGES
• 208, 240 and 480V single-phase and
three phase delta. Convertible from three-
phase to single-phase (in field) and vice
versa (except 208/54 kW). 277V single-
phase also available.
TERMINAL BLOCK
• Factory installed. Allows for easy service
connection to block.
MAGNETIC CONTACTORS
• Heavy duty; UL rated 100,000 cycles.
THREE YEAR LIMITED TANK
WARRANTY
• For complete warranty information,
consult written warranty or go to
americanwaterheater.com.
OTHER STANDARD FEATURES
• Immersion style thermostats
• Simplified circuitry, color coded for ease
of service
• Hinged control compartment door for
quick, easy access
• Two anode rods for maximum corrosion
protection
• Cabinet has bonderized undercoat with
baked enamel finish
• Top outlet, side inlet and relief valve
openings
• Nipple and brass drain valve
• CSA certified and ASME rated T&P relief
valve.
