Commercial Electric Water Heater

GOLD Xi™ SERIES ­COMMERCIAL ELECTRIC WATER HEATERS

Designed for use as a recovery heater having its own storage tank or booster for supplying
sanitizing rinse water for dishwashing.

FEATURES

Meets or exceeds the thermal effi ciency and or standby loss requirements of the U.S.
Department of Energy and current edition of ASHRAE/ISENA 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.

iCOMM™ COMPATIBLE - Call 1.888.WATER02 for more information.

ECONOMY MODE OPERATION - Control system automatically lowers

the Operating Set Point by a programmed value during user- defi ned time
periods. Helps reduce operating costs during unoccupied or off - peak demand periods.

MODELS

DVE-52, 80, 120

LINEAR SEQUENCING - Banks of heating elements (3 elements per bank) are energized

according to adjustable (1 to 20°) 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 DVE 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 A. O. Smith for water heater use. Tanks rated at 150 psi working
pressure; tested at 300 psi. Foam insulation reduces costly heat loss. ASME (optional) maximum
working pressure is 150 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 fi eld) 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 contact A. O. Smith.

OTHER STANDARD FEATURES

Immersion style thermostats
control compartment door for quick, easy access Two anode rods for maximum corrosion
protection Cabinet has bonderized undercoat with baked enamel fi nish Top outlet, side inlet
and relief valve openings Nipple and brass drain valve CSA certifi ed and ASME rated T&P
