Features

1.Comfortably-off home water heater

Collector equipment is aslant installed on the rooftop and perfectly consists with architectures around, which corresponds to the architectural standard fashion nowadays.

2.Heat tube coupling is efficient and reliable

Heat tube coupling is fast and conductive. Vacuum tube of collector equipment is without water and dirt, freeze-proof, high endurance, efficient and secure.

3.Selective coat endothermic system

The endothermic system adopts the latest international high-tech and absorbs coats selectively. It is characterized by high absorbing capacity and low reverse shape.

4.Hot water system of enduring pressure

A single machine can use the full system of enduring pressure in more than one way. Water is supplied in more than one line. There exists a large water stream, comfortable water supply and convenient water temperature. System functioning is reliable and can be used under all whether conditions.

5.Humanity design

Four special working modes are designed to supply water under different season climate environments.To automatically adjust linearly the circulating speed of water pump according to temperature difference. To save energy and to extend longevity of water pump. To ensure there exists the water temperature indication. To protect with low and high temperatures, and to use securely and conveniently.

Notes for usage

1.To avoid that water spurts out to the pump and the top cover of water-storing tank.

2.To check the functioning of the system regularly and to check whether the computer board works normally.

3.In order to ensure excellent running of solar water heater, you are suggested to keep the controller electrified constantly and keep it working under the solar energy heating mode.

4.In normal use, the tap water entrance valve of water-storing tank should be kept constantly open. You only need to open the mixed valve to adjust water temperature when taking a bath and then you can use freely.

5.Please pay attention to the temperature of water-storing tank when taking a bath and avoid being scalded by too hot water or being hurt by too cold water.

6.Please try to connect the probe of sensor to the bottom of the installed hole in installment or repair. Please avoid that the sensor receives wrong signals.

7.In winter when water heater is not used for long, the system should be closed and emptied in order to damage water heater as a result of icing. The emptying method is to close the valve where tap water pipe leads to the hot water system, to adjust the the mixing valve on the hot water place, then to open the decompression handle of safety valve and to empty the system.In order to make the emptying process convenient, you are suggested to purchase water releasing pipe (otherwise sold)in installment.

8.In summer when water heater is not used for long, please close the water-inlet valve so as to avoid the suddenness occur, at the same time empty the system. Before empty the system, please use hardboard or other same material to shade the collector fully, after empty the system,you had better tear down the whole circulating pipe so as not to burn the pipe as the sun high tempreture.In order to make the emptying process convenient, you are suggested to purchase water releasing pipe (otherwise sold)in installment.

9.In cases when the power supply line of the appliance is damaged, it is the personnel of after service who change that for specially designed lines (provided by the manufacturer).

10.When the system runs continually over one month, you are suggested to check regularly whether the deviation of the clock is large so as to adjust the clock promptly and ensure that the preset and intellectual heating modes operate normally.

11.In cases when the temperature of water-storing tank exceeds 85 , and the display board of the line-controlling lindicates E2, you should cut off power supply and release an appropriate amount of hot water as well as supplement cold water. When the temperature drops, you should connect power supply again, which can eliminate malfunction.
