Yes.
Solar environment: 1. Use a flathead screwdriver to open the liquid filling port and exhaust port. 2. Open the media in button and media outlet button under the water tank. The liquid in the water tank will flow out naturally and the antifreeze in the water tank will be drained. 3. Use an air pump to inject gas into the fluid outlet, and rely on the gas pressure to discharge the antifreeze into the flat plate or vacuum tube. 4. Exhaust. The liquid is pumped through the mouth and filled as it exits the injection port.
Solar fluid is actually antifreeze. When adding it, you usually need to add around 20 liters. This should be taken into account according to the actual situation.
Need to add.
There is a thermal fluid injection port on the water tank. Open the injection port cover, use a thin tube toinject antifreeze, then tighten the cover. By the way, correction, the thermal fluid currently used in flat panel solar collectors is called "antifreeze" and is not generally called a thermal fluid.
