1. Take a used towel and lightly wipe the vacuum tube of the solar water heater to make the next disassembly step easier.
2. Wearing gloves, take a thin piece of bamboo or wood and slide the dust-proof sealing ring about 30 centimeters from the upper end of the vacuum tube where it contacts the solar thermal insulation barrel .
3. When disassembling, start from the outermost part of the solar power, hold the upper middle part of the vacuum tube with both hands, apply slight force, rotate and shake the collector tube left and right, and gradually try to apply more force until the vacuum tube can shake.
4. After you can shake it, hold the tube wall firmly with both hands and push it upwards while shaking it, so that the vacuum tube rotates and rolls upwards, about 10 centimeters into the insulation .barrel.
5. Once the bottom of the vacuum tube is completely separated from the solar bracket, lift the bottom of the vacuum tube slightly, rotate it downward, and slowly remove the vacuum tube. The most difficult is the first. You will feel it after removing one. The following ones will no longer be difficult. Use the same method to remove the remaining vacuum tubes from the water heater.
6. Insert your index and middle fingers into the hole in the insulation barrel and remove the sealing rings from all pipe openings. This completes all dismantling work.
What to do if the scale in the solar vacuum tube cannot be discharged
Method 1:
If it is convenient for you, you can remove the vacuum solar tube, fill it with appropriate amount of white vinegar and soak it for 10 minutes, then use the brush to pull back and forth to remove the remaining scale, then rinse it twice with waterclear.
Method 2:
1. If it is inconvenient to remove the vacuum tube, you can open the water inlet of the solar water heater and add white vinegar to the water tank.
2. Automatically heat for 20-30 minutes to completely contact all parts with the white vinegar solution, then open the drain and drain the white vinegar that cleaned the scale.
3. Fill the water tank with water and then circulate it for 2 minutes, then drain the circulating water, and the cleaning and descaling work is completed.
4. Due to chemical reactions, vacuum tubes soaked in white vinegar or washed with circulation methods will have an unpleasant odor. After cleaning, you can use lemon juice to scrub it or add some during circulation. can be used to remove flavor.
Summer is coming. In order to avoid too much scale due to temperaturee water too high, industry insiders recommend using a cloth.
The cleaning method is as follows: 1. Remove the vacuum tube. , handle it gently, do not crush it into pieces; 2. Pour out the tartar; 3. Clean the scale on the inner wall of the solar vacuum tube. This requires the use of a special acid descaler. Pour in an acidic scale remover and soak for about ten minutes, then use a brush to pull back and forth to remove the remaining scale, then rinse twice with clean water.
That's it. he. Note: It is best to wear gloves when cleaning to avoid burns and skin burns. It is best to use the water the day before, take it out and wash it the next morning, do it before sunrise, and then refill the water, so as not to affect the use results of the day. 4. If you hire a professional cleaning teamage and solar maintenance, it will be more reliable and reduce the risk of damage. Recommendation: block half of the sun's rays in summer. Scale only forms when temperatures are above 70 degrees Celsius. Therefore, block the light to cool and extend the usage time.between.
