1. As shown in the figure, the upper pipe is a water supply pipe and the lower pipe is return pipe. We must close the manual valve of the return pipe below.

2. Turn the manual valve of the return pipe to the vertical position to close the return pipe.

3. As shown by the red circle in the figure, this is the drain valve.

4. Unscrew the drain valve.

5. Put the other end of the drain valve hose into the bucket to prevent the bottom surface from getting wet.

Radiator maintenance:

1. Pretreatment Firstly, degrease the radiator with anti-corrosion coating and phosphatize the outer surface.

2. The cathodic electrophoretic paint adopts the "cathodic electrophoretic primer coating process" used in the automobile manufacturing process to ensure that the outer surface of the radiator has better resistance to "moisture or other harsh environmental influences".

3. Electrostatic spraying of all-polyester plastic powder adopts equipment imported from Switzerland to carry out computer-controlled electrostatic spraying of polyester plastic powder, so as to create a colorful and bright appearance of the radiator and better "dustproof, moisture-proof, acid-resistant and scratch-resistant" ability. The surface plastic powder is made of environmentally-friendly raw materials, which avoids the emission of harmful gases after the temperature of the radiator in the heating, and makes your life more sunny and healthier!

4. High-temperature baking. Finally, bake at the temperature of 200 degrees Celsius, so that the surface of the radiator of the radiator is solidified with polyester resin plastic powder, and it will keep lasting brightness!
