Open the cover, unscrew the fixing screw of the front middle net, and then remove the front middle net and put it away. Prepare a toothbrush or brush and brush the condenser from top to bottom to remove catkins and impurities on the surface. Connect the car wash hose to the faucet, assemble the water gun and water pipe after turning off the faucet, and then check whether the installation is firm. Turn on the tap, properly adjust the pressure of the water gun, and clean the condenser from top to bottom to avoid cleaning from left to right, so as not to damage the heat sink. When the condenser surface cleaning is completed, a lot of black dirty water will flow out from the bottom of the car, so it is necessary to continue cleaning at this time. When the flowing water is clean and transparent, it means that the condenser and water tank have been cleaned. It can be restored in the reverse order of disassembly and assembly.

Start the car, turn on the air conditioner, let the electronic fan rotate, and rinse the condenser thoroughly with clean water; 3. Spray the washing products on the surface of the condenser with a water spray tool, and use an electronic fan to absorb them to all corners; 4. Start the air conditioner again and rinse the condenser with plenty of clean water until it is completely cleaned.
