A. O. Smith DEL-10 User Manual

Commercial Electric

Water Heaters

Designed for use as a recovery heater having its own storage tank. Available in upright standard models (DEN) and lowboy models (DEL).

GLASSLINED TANK

glass specially designed by A. O. Smith for water heater use.

- Thirteen sizes; 6 thru 119 gallon capacity. Tank interior is coated with

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. (No junction box on DEL6-20)

CONTROLS - Temperature control (adjustable through arange of 110° to 170°F on single element

and 120° to 180°F on dual element) 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).

Recovery capacities at 100° F rise equal: for non-simultaneous element operation = 4.1 gal. x kW of one element; for simultaneo us element operation = 4.1 gal. x 2/3 kW of both elements. For other rises multiply element kW as previously explained by 410 and divide by temperature rise. Full load current for single phase = total watts :- voltage.
