Descripción del producto:

Se trata de un sistema presurizado, con depósito directo y colector solar plano combinados, que denominamos calentador de agua solar presurizado compacto de panel plano.

Los sistemas de circuito abierto son una forma sencilla y rápida de calentar agua. Son más adecuados para regiones de clima cálido porque funcionan directamente con agua potable. Los sistemas de circuito abierto no se recomiendan en regiones donde la calidad del agua no es lo suficientemente buena.

Cómo funciona:

El sistema funciona según el principio de termosifón, adopta el tipo de circulación agua-agua. La membrana de adsorción de calor de la placa plana absorbe el calor solar para calentar directamente el agua en el colector de calor. El agua calentada se suministra a la parte superior del acumulador de agua caliente a través de la tubería de circulación y el agua fría no calentada de la parte inferior fluye hacia el colector de calor de tipo plano como suplemento. A continuación, el agua fría se calienta y se envía al acumulador de agua caliente. La circulación del agua se repite hasta que toda el agua del depósito se calienta a la temperatura especificada.

Open Loop Flat Panel Solar Water Heater Manual

1.1 Advanced technology
The core parts of the solar water heater – flat plate solar collector and enameled steel inner tank involve numerous national patented technologies. The solar collector with advanced technology in gathering solar energy features water-tightness, high heat absorption, independent heat supply, fast energy output, wide scope of application and long working life.

1.2 Low heat loss
With imported polyurethane foam en-bloc high pressurized, which is of high density and strength, the solar water heater has excellent heat insulation.

1.3 Superb process technology
The inner tank is made of special steel, formed up with advanced punching technology and auto non-electrode replacing welding technology. A special silicate is sintered by high temperature to the inner tank’s walls, forming a special protection layer featuring freedom of leakage, rust/erosion and scaling, thereby effectively preventing leakage between the water tank and the heat-gathering tubing and ensuring the cleanness of water.

1.4 Easy for functional extension
This solar water heater can be equipped with a computerized controller and electric heater. The user has a few options depending on his actual needs.

3.3 Connection between solar panel and water tank
Please pay attention to the following drawing and picture when installing pipelines.

Connection between solar panel and water tank
If solar water heater is equipped with two or three units of solar collectors, please see the connection of two solar collectors from the marks C and D.
3.4 Installing computerized controller
If the solar water heater is equipped with one computerized controller, please carefully read the Controller’s User Manual before installing and operating the Controller.

The Controller should be located in a prominent location that is accessible to the homeowner. Care should be taken to ensure that the controller is not placed where it is within easy reach of children, near electromagnetic fields or in damp locations.

Attention!
▲ The socket and plug should be connected well.
▲ If electric heater is installed, do connect the live wire, null wire and ground wire correctly with power-leakage protection plug. The socket should be connected to ground reliably.
▲ Use tri-wire plug of safe protection, and the rated current value of socket ≥10A.
▲ Wiring according to controller instruction manual.


4.1 Prohibition of isolation without water
Under normal circumstances, keep the water tank full. If the solar water heater is not used for a long time, the heat collecting tubes should be covered with shade cloth.

4.2 No shadow
The solar collectors face south without shelter.

4.3 Wind stress
When installing solar water heater, please consider the issue of wind resistance, and resultant stress on attachment points.

4.4 P/T valve

4.4.1 Please refer to separate P/T valve instruction manual for operating.
4.4.2 Following installation, the P/T valve lever MUST be operated AT LEAST ONCE A YEAR by the solar water heater owner to ensure that waterways are clear.
4.4.3 The P/T valve should be inspected AT LEASE ONCE EVERY TWO YEARS, and replaced, if necessary.

4.5 Magnesium anode
The magnesium anode should be inspected at the timely basis to extend the life of water tank according to water quality.
Replace the magnesium anode AT LEAST ONCE TWO YEARS.

4.6 Water Quality
In areas with “hard” water, lime scale may foam inside the safety valve and P/T valve. In such regions, it is advisable to install a water softening device.

4.7 Expansion tank
In areas with high temperature weather, the pressure inside water tank rises quickly. It is an optional means to install a suitably sized expansion tank significantly minimize the amount of hot water dumped by the P/V valve due to overpressure.

Assembly, maintenance and repair shall be carried out only by qualified technicians. If the problems fail to be solved, please contact the local distributors/installers.
