Attentions in installment Installation

Attentionsinstallment

Electric controller should be far from strong interfering sources.

Tne-way pipeline between water-storing tank and collector equipment must be less than 10 meters.

Sensor of collector equipment should be installed at the water exiting Opening.

The exhaust valve should be installed vertically at the water exiting opening of collector equipment and its position in the pipeline should be kept the highest. To screw loosely the exhaust cap after installment to make it exhaust freely.

Pay attention the crossing corner of water entering and exiting opening should be connected and the bottom one is for water-entering and the top one is for water exiting in the installment of collector equipment with flat board.

Installation

Installment of solar water heater is composed by the following parts: installment of collector equipment, installment of water-storing tank and installment of water pump. Installment of each part should be completed by the professional installing personnel appointed by our company in order to ensure good functioning of the system.

Installment of collector equipment

Collector equipment of solar water heater is installed with the method of oblique top. collector equipment is placed on the southern rooftop of the house so as to ensure that the equipment faces south and there is no shelter ahead. All the four corners of each collector equipment are linked perfectly with steel wire rope. the other end of the steel wire rope is fixed under eaves or on the wallwith a expanding bolt. Pay attention that the steel wire rope is strained and the expanding bolt is beaten firmly. Take the installment of solar water heater of BRF1-120/150W as an example. For the sketch map of installment, please see Fig.3.

storage. in cases when the machine is turned on, press the mode key to enter the solar energy heating mode (Note: the first time the system is electrified, this mode can be entered). The green point is in the working indication icon is on in the solar energy heating. Press the setting key and you can adjust the

clock and choose temperature difference value (6 or 10 , the tacitly approved value is 10 ) of the water pump running. When the starting conditions for water pump are reached, then the water-exiting temperature of collector equipment 20 . Meanwhile, when temperature difference between water-exiting of collector and water in Water-storing Tank is higher than the set value (6 or 10 ), water pump will start and run at full speed. When the temperature difference is less than 2 , water pump will automatically stop.

B. simultaneous heating:turn on the machine , press the mode key to enter the simultaneous heating mode. The green point of this heating is on. To

automatically start electrical heating according to the preset 65 of the system and the red point glistens. Press the setting mode and you can set water temperature 30 -75 .When reach the preset temperature, the electrical heating will stop automatically . The working mode will automatically leap from this mode to the solar energy heating mode. If the present water temperature is higher than that set previously, this kind of heating can not start.

C. preset heating: this function automatically works out the time needed to the set temperature according to the tacitly approved heating power (1KW), and then ensures the time when water heater begins to heat. This mode can realize both one-time preset and twice preset. You can choose either heating method based on your practical life necessity. If you need one-time preset heating, press the setting mode to set the time of the two presetting as the same. If you need twice preset heating,set the two times respectively. (Note: the setting order is irrelevant to the time set). The preset time is subject to the clock time of the system. In cases when the machine is turned on, press continually the mode key to enter the preset heating mode. The green point in the working indication icon is on. Press the mode key and you can set each preset time and their respective preset temperature 30 -75 . Note: in this mode, the solar energy heating is not concerned. If the preset temperature is reached before the preset time, the system will automatically start electrical heating each time the system drops 5 until the preset time is reached.

If the temperature has not reached the preset one after the preset time is reached, then the system will delay at most half an hour for heating.

D. Intellectual heating: this function automatically classifies and analyzes the latest seven-day bathing regularity and memorizes the period of time that customers have a bath most frequently within the seven days. And it then
