Designed for use as a recovery heater having its own storage tank. Note: Not recommended for sanitizing water application.
FEATURES
GLASS-LINED TANK - Three sizes; 52, 80 and 119 gallon (189, 300, 450 Liter) capacity. Tank interior is coated with glass specially developed by A.O. Smith Ceramic Research for water heater use. Tanks rated at 150 psi (1034 kPa) working pressure (ASME 160 psi [1100 kPa]). Foam insulation reduces costly heat loss, and is vermin proof.
ELEMENTS - Incoloy sheathing for longer life. Low watt density; means lower surface temperature to minimize scale buildup and more surface to heat water. Element sizes from 3 to 6 Kw. Use 3, 6 or 9 elements standard; total of 6 to 54 Kw input (see chart on back).
STANDARD VOLTAGES - 208, 240 and 480V single-phase and three-phase delta; 277V single-phase also available.
TERMINAL BLOCK - Factory installed. Just bring the service to the heater and connect to block.
CONTROLS - One temperature control adjustable through a range of 120° to 180°F (49° to 82°C) and manual reset high temperature cutoff per element. Thermostat step control may be achieved by varying settings on individual temperature controls. Located behind hinged control compartment door for quick, easy access.
