1. The alarm can be an ultra high temperature alarm. Because the water temperature in the water tank is too high, in order to prevent the vacuum tube from bursting due to cold water, this function is provided. but other reasons cannot be excluded. For details, please refer to the supplied instrument instruction manual or ask the buyer for details. The water pressure is too low and the water tank temperature is too high, which will cause this phenomenon.
2. Check the tap water pressure. For automatic water filling, check whether the solenoid valve can open automatically and whether there is a problem with the setting. When filling the water manually, check if the pipe is clogged.
3. There is a lot of dust deposited on the surface of the vacuum collecting tube and the reflecting plate or there are obstructions; vacuum collector tube leaksand loses vacuum, the heat pipe fails; bad, the solar radiation energy is insufficient and the temperature is low; the water tap is not closed tightly and the water fills or flows slowly. Wipe the dust on the surface of the vacuum collecting tube and the reflecting plate, and remove the obstruction; replace the vacuum collection tube; use an electric auxiliary heater;
Detailed information:
1. It is strictly prohibited to spray water on electrical parts when taking a bath, especially when using a bathroom heater. It is strictly forbidden to operate the electrical parts with wet hands. Cut off the power supply to the auxiliary heating system and the antifreeze belt before swimming. It is strictly prohibited to use the leakage protection cap as a switch. startfrequently electrical parts.
2. It is strictly prohibited to use solar water heaters during thunderstorms and windy weather.
It is strictly prohibited to use solar water heaters during thunderstorms to avoid electric shock. Due to its working principle, solar water heaters should be installed on the upper balcony. Solar water heaters are generally larger in size due to their heat collection requirements. Therefore, users should pay attention to reinforcing the supports of solar water heaters in windy weather to avoid accidents. Be sure to fill the water heater with water on windy days to increase stability.
3. Scientifically choose watering time.
Solar water heaters must be filled with water regularly, but it is strictly prohibited to fill water when the weather is particularly hot and the temperaturewater temperature is particularly high. It is strictly forbidden to add water immediately afterwards. the water is exhausted. Due to the strong sunlight in summer, the temperature of solar vacuum tubes in the air reaches 270 degrees Celsius to 400 degrees Celsius when exposed to sunlight. At this time, the water supply can easily burst the vacuum tubes.
It is best to fill the water two hours before sunrise in the morning or after sunset in the evening, to ensure the life of the solar vacuum tube.
