Operating Instructions

SECTION VII

SYSTEM START-UP

Follow solar collector installation instructions to place collector in operation. Ensure that solar fluid flow operation is established for the installed system.

SEQUENCE OF HEATING OPERATIONS -SOLAR AND ELECTRIC BACKUP

1.The solar controller senses a large enough temperature difference between the lower tank and the solar collector to transfer heat into the tank.

a.The solar controller activates a circulator/pump to flow fluid through the heat exchanger and solar collector, transferring heat into the storage tank until the temperature difference is significantly reduced.

2.The upper element thermostat senses that the water temperature stored in the upper portion of the tank drops below the desired setting.

a.The upper element is energized to heat stored water to the desired temperature. Once the water in the upper tank is heated to the desired temperature, the element is de-energized.

3.The lower element thermostat senses that the water temperature stored above the solar heat exchanger drops below the desired setting.

a.The lower element is energized to heat stored water to the desired temperature. Once the water in the lower tank is heated to the desired temperature, the element is de-energized.

WATER TEMPERATURE ADJUSTMENT

Table 7 details the approximate relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.

WARNING

SCALDING

This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. By setting the thermostat on this water heater to obtain an increased water temperature, you may create the potential for scald injury. To protect against injury, you should install an ASSE approved mixing valve (a device to limit the temperature of water to protect against scald injury via mixing hot and cold water supply) in the water system. This valve will reduce point of discharge temperature in branch supply lines. This water heater was shipped with an ASSE approved mixing valve. Install this valve according to the directions in the mixing device container. DO NOT OPERATE THIS WATER HEATER A MIXING DEVICE. If this water heater was shipped without a mixing device, contact the manufacturer.

Water temperature over 125°F can cause severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of being scalded.

Review this instruction manual before setting temperature

at water heater.

Feel water before bathing or showering.

Temperature limiting valves are available.

Solar Water Heater specifications

Bradford-White Corp is a well-known name in the water heater industry, and among its innovative offerings is the Solar Water Heater, a solution that combines sustainability with performance. As consumers increasingly seek energy-efficient alternatives, Bradford-White has successfully positioned itself as a leader in solar technology.

One of the key features of the Bradford-White Solar Water Heater is its ability to harness energy from the sun to provide hot water. This system uses solar collectors that capture sunlight and convert it into thermal energy. The solar collectors can be roof-mounted or ground-mounted, making them adaptable to various property designs. They are typically made with durable materials designed to withstand harsh weather conditions, ensuring longevity and consistent performance.

The technology behind Bradford-White's solar water heating system includes a closed-loop system that circulates a heat transfer fluid through the solar collectors. This fluid absorbs heat and is pumped to a storage tank where heat exchangers transfer the energy to the water. This means that even on cloudy days, the system can still deliver energy-efficient hot water.

Another characteristic of Bradford-White solar water heaters is their compatibility with conventional water heating systems. This means that they can be installed as a stand-alone system or as a supplementary component to existing water heating units, offering flexibility depending on household needs and preferences. The integration of solar technology not only reduces energy bills but also lowers greenhouse gas emissions, making it an environmentally friendly choice.

Moreover, these systems are designed with user-friendly controls, enabling homeowners to monitor and optimize their hot water usage effortlessly. The advanced controls often come with features such as programmable settings, allowing users to take full advantage of solar energy during peak sunlight hours.

Bradford-White also prioritizes safety and efficiency in its solar water heaters. The systems are equipped with various safety features, including pressure relief valves and freeze protection measures to prevent damage in colder climates. The energy efficiency ratings are impressive, often exceeding industry standards and providing consumers with peace of mind regarding their investment.

In conclusion, Bradford-White Corp's Solar Water Heater presents an innovative solution for reducing energy costs while promoting sustainability. With advanced solar technology, durable construction, and user-friendly features, this system is an excellent choice for environmentally conscious consumers seeking reliable hot water solutions.
