Tanks rated at 125 psi working pressure; 150 psi or 160 psi working pressure is optional. Vermin proof fiber glass insulation reduces costly heat loss. Constructed to Section IV of ASME code, and UL standards. Tanks have channel skid base. A 4" x 6" handhole is furnished on 500, 600 and 700 gallon models; 11" x 15" manhole is furnished on 800 gallon and larger sizes. INCOLOY IMMERSION HEATERS — Heavy-duty medium watt density elements (three/immersion heater) have incoloy sheathing: provide excellent protection against oxidation and scaling. The input ranges from 15KW to 3000KW (see accompanying chart). AVAILABLE WITH OPTIONAL GOLDENROD ELEMENTS — All models are available with the Goldenrod 24K gold plated elements (patent pending). Goldenrod Elements provide long- life and five times the scaling resistance of standard incoloy elements. Goldenrod Elements carry a three-year warranty against failure due to scale. FUSING — Control and power circuit fusing to meet N.E.C. PILOT SWITCH AND LIGHT — Provided on front of heater; permits manual starting and stopping of heater by interrupting power to control circuit. MAGNETIC CONTACTOR(S) — Heavy duty UL rated for 100,000 cycles. LOW WATER CUTOFF — Probe type electric low water cutoff prevents energizing of elements in the event of low water condition. 120 VOLT CONTROL CIRCUIT — 120 volt control circuit is powered by fused transformer. IMMERSION THERMOSTAT — Immersion temperature control (one per 60KW) is adjustable to 180°F; high temperature cutoff is manual reset, adjustable type. LIMITED WARRANTY OUTLINE If the tank should leak any time during the first three years, under the terms of the warranty, A. O. Smith will repair or replace the heater; installation, labor, handling and local delivery extra. THIS OUTLINE IS NOT A WARRANTY. For complete information, consult the written warranty or A. O. Smith Water Products Company. Warranty does not apply to product installed outside of the United States of America or its territorial possessions and Canada. ASME COMMERCIAL ELECTRIC WATER HEATERS DVE–125 THRU 10,000 DHE–200 THRU 10,000 MEETS OR EXCEEDS THE REQUIREMENTS OF ASHRAE 90.1b-1990 STANDARD FOR ENERGY EFFICIENCIES. OTHER STANDARD FEATURES • Color coded circuitry for easier servicing • Anode rods for maximum corrosion protection • Standard voltages include 208, 240, 480, 600 volt single or three-phase. For other voltages consult factory. • Factory installed terminal block(s) • Cabinet has baked enamel finish • Prewired element terminal leads • Temperature and pressure relief valve • 2" dial temperature gauge • Immersion type thermostat and high limit for faster response. OPTIONAL DUAL ENERGY SOURCE CAPABILITY — Provides emergency back up energy source or winter/summer boiler operation. Can be specified with optional water to water or steam to water heat exchangers. Both single and double wall heat exchangers are available. Complete control packages can be factory installed for hook-up and run capability.
