Bradford White S-SW2-60R6DS User manual

EcoStor™SC Solar Indirect System
Single Coil Electric Backup Models
The EcoStor™Single Coil Models feature:
■Internal Single Wall Heat Exchanger—Single Wall 11⁄2"O.D. glass coated
(Vitraglas®)steel coil. The coil has a heat transfer area of 14.2 sq. ft. and a
stored water volume of 2.5 gal. Maximum supply temperature from the solar
collector must not exceed 250°F.
-- 1" NPT Front Supply and Return Connections.
■Sensor Wires for Solar Thermistor Connections—Twisted wires are
provided under the Upper and Lower covers. These wires have been
provided as a means for connecting thermistors to a solar controller
(Thermistors and Solar Controller are not provided).
■Integrated Mixing Device—Features an accurate, easy to use hand wheel
for adjusting mixed water temperature, a pre-piped stainless steel flexible
connector for quick installation as well as optional water connections (1/2"
NPT recirculation inlet, 1/2" NPT hot water outlet, 1/4" NPT cold water
outlet). This required system is easily installed and ensures a comfortable
outlet temperaturewhile providing a steady flow of hot water.
■Backup Element(s)—Adual, or single backup heating element provides
heat only when solar energy does not satisfy demand. Dual element
models allow entire tank to hold hot water during periods where solar
heating is not available.
■FactoryInstalled Hydrojet®Total Performance System—Cold water inlet
sediment reducing device helps prevent sediment build up in tank.
Increases first hour deliveryof hot water while minimizing temperaturebuild
up in tank.
■Vitraglas®Lining—BradfordWhite tanks arelined with an exclusively
engineered enamel formula that provides superior protection from the highly
corrosive effects of hot water. This formula (Vitraglas®)is fused to the steel
surface by firing at at temperature of over 1600ºF.
■Fully Automatic Controls—Fast acting surface-mount thermostat(s) for
automatic temperaturecontrol. Factory installed sensitive manual reset
energy cutoff for safety to prevent overheating.
■2" Non-CFC Foam Insulation—Covers the sides and top of tank, reducing
the amount of heat loss. This results in less energy consumption, improved
operation efficiencies and jacket rigidity.
■Potable Water Connections—3⁄4" NPT factory installed true dielectric
fittings extend water heater life and eases installation.
■Two Protective Anode Rods—Provide added protection against corrosion
for long trouble-free service.
■Direct Heat Transfer With Immersed Incoloy Element(s)—Transfers heat
directly and efficiently to the water. Screw-in style.
■T&P Relief Valve—Included.
■Low Restriction Brass Drain Valve—Durable tamper proof design.
6or 10-Year Limited Tank Warranties / 6-Year Limited Warranty on Component Parts.
