FEATURES

GLASS-LINED TANK - Thirteen sizes; 6 thru 119 gallon (22 thru 450 liter) capacity. Tank interior is coated with glass specially developed by A. O. Smith Ceramic Research for water heater use. Tanks rated 150 psi (1034 kPa) working pressure; tested at 300 psi (2068 kPa). Foam insulation provides maximum energy savings by minimizing radiant standby heat loss.

ELEMENTS - Zinc plated copper sheaths for longer life. Medium watt density; means lower surface temperature to minimize scale build-up and more surface to heat water. Element sizes from 1.5 to 6 KW. Maximum input 12 KW (see chart on back).

STANDARD VOLTAGES - 120, 277 single phase and 208, 240 and 480V unbalanced three-phase delta; easily converted to single-phase at terminal block (except 208V with 6000 watt elements). Single element heater, single-phase only.

TERMINAL BLOCK - Factory installed. Just bring the service to heater and connect to block. Terminal block not supplied on 120V & 277 volt models.

CONTROLS - Temperature control (adjustable through a range of 110° to 170°F [43-77°C]) and manual reset high temperature cutoff per element (dual element models). Factory wired for non-simultaneous operation; easily converted to simultaneous element operation (three phase models only).

OPTIONAL

GOLDENROD ELEMENTS - All DEN & DEL models are available with the Goldenrod® 24K gold plated elements (patent pending). Goldenrod® elements provide long life and 6 times the scaling resistance of standard incoloy elements. Goldenrod® elements carry a three-year warranty against failure due to lime scale build-up.

Meets or exceeds the requirements of ASHRAE 90.1b-1992 Standard for energy efficiencies.
