Please make sure that the sockets are subject to national standards and are connected to the ground reliably. It is prohibited to use water heater without a reliable grounding. The water heater is equipped with safety valves. for secure use, please do not change installment position personally. The evacuating tube nozzle should be downwards vertically and are open to the air so as to prohibit jamming the exit. A draining pipe is linked to the evacuating tube nozzle and leads to the sewer opening. (the draining pipe is otherwise sold) Hot water with a temperature higher than 50 might result in scalding and customers should mix hot water and cold water and then have a shower or wash.

Therefore, when you wash rice and vegetables with water in the container, please wash them once again with clean tap water. When collector equipment is installed, it can not be inversely placed. Outdoor pipeline must use metal pipes. Heat-preserving of pipelines must use specially designed materials by our company. Collector equipment should be installed facing south. Evacuating opening of the system safety valve should be connected to the release opening of sewage. All parts of the whole system are not allowed to be disconnected personally otherwise, results should be burdened personally. 411 Attentions in installment Installation Use method Attentions in installment Installation Use method 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.

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. Collector Steel wire rope Expanding bolt Fig.3 Installment sketch map of BRF1-120/150W 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).
