When the pressure difference ratio between hot water and cold water exceeds 8:1, a flow-limiting pressure reducer should be installed on the high pressure side to ensure normal valve adjustment mixer. When selecting and installing a solar water mixer, care should be taken to ensure that the rated pressure and temperature range requirements of the mixed water are consistent with the product parameters.
During the installation process of the mixer, make sure to read the labels clearly. There is a red label for the hot water inlet and a blue label for the cold water inlet. Pay attention to distinguishing the cold water inlet. the water inlet and the hot water inlet. After adjusting the temperature of the solar water mixer, if the water temperature and water pressure change, the outlet water temperature change value is (+2). If the hot water pressuree and cold water is inconsistent, a one-way check valve should be installed at the water inlet to prevent the interaction of hot and cold water.

Installation of other mixers
1. Installation method of kitchen mixer:
The installation of kitchen water mixer should be firm, because the kitchen water mixer is used very frequently and can easily loosen after one use prolonged, the mixer nut must therefore be tightened. There are now mixing valves on the market that use enlarged screws and nuts to secure them. This type of stabilizing effect is very good and may become a popular trend in the future.
2. Bathroom mixer tap installation method:
When installing a bathroom mixer tap, the core of the bathroom mixer tap should be pre-buried into the wall. Before pre-embedding, you must keeptaking into account the thickness of the bathroom wall. If the wall is too thin, the valve core will not be able to be pre-recessed. Do not prematurely remove the plastic protective cover supplied with the valve core during embedding to avoid damage to the valve core by cement and other stains during embedding. In addition, when pre-embedding the valve core, you should also pay attention to the direction of the valve core to avoid incorrect integration of the valve core. There is a gap in the size of the bathroom mixer when it is integrated into the water inlet pipe. You can use the adjustable crimp to correct it.
Can solve the problem of hot water backflow. Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in the living room.e and production.
Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.
Home evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.

Solar water heater installation precautions:
p>< p >1 Due to the low temperature and short sunshine in winter, when installing asolar water heater, outdoor pipes and exhaust overflow pipes should be covered with rubber-plastic insulation pipes first, and then insulated with thicker polystyrene materials to avoid. The water freezes, causing hot and cold water to flow smoothly and can even damage the solar water heater tank.
2. If the pipeline is not take the flue and the exterior of the building because the pipes are fixed on the side wall of the building to ensure safety and beauty. When connecting the pipe fittings to the water corner of the solar thermal water heater, use a wrench or pipe wrench to. tighten the water nozzle, then connect it to other parts.
3. Pay attention to weather conditions, especially temperature. If the temperature is not too low, if there is still hot water in the water tank after using water that night, refill it immediately.ent; the temperature is relatively low at this time, the water must be refilled the next day; if the weather is bad the next day, raining or snowing, the water should be refilled according to the water situation at home and try not to do so. fill it with water.
4. When the temperature is below zero, be sure to open the hot water faucet of the solar water heater to flow water to ensure smooth flow of solar water and prevent dripping pipes. water from freezing.
