Glasslined Tank - Thirteen sizes; 6 thru 119 gallon capacity. Tank interior is coated with glass specially designed by A. O. Smith® for water heater use. 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. Standard Voltages - 120, 277 single phase and 208, 240, and 480 V unbalanced three-phase delta; easily converted to single-phase at terminal block (except 208 V 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 120 V & 277 V models. (No junction box on DEL6-20). Controls - Temperature control (adjustable through arrange of 110 to 170 ºF on single element and 120 to 180 ºF 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). Simplified Circuitry, Color Coded for Ease of Service. Anode Rod for Maximum Corrosion Protection. Cabinet has Bonderized Undercoat with Baked Enamel Finish. Top Inlet and Outlet Openings. Drain Valve (Excludes DEL 6 to 20). |

Note
Note |
N/A Recovery capacities at 100 ºF rise equal: for non-simultaneous element operation = 4.1 gal. x kW of one element; for simultaneous 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. |
