How to properly clean and maintain the water tank of a 250W Evaporative Air Cooler Chiller?

During daily use, the water tank of a 250W Evaporative Air Cooler Chiller is prone to accumulate dust, scale and microorganisms, so it is recommended to perform basic cleaning once a week. First, be sure to disconnect the power supply to ensure safe operation. Then open the drain valve at the bottom of the water tank or tilt the body to drain the remaining water thoroughly. Next, rinse the inside of the water tank repeatedly with clean water to remove the deposited impurities. For stubborn stains, you can use a soft cloth or sponge to dip a small amount of neutral detergent and gently wipe the inner wall. Avoid using strong acids, strong alkalis or corrosive detergents to avoid damaging the material of the water tank. Finally, rinse the water tank thoroughly with clean water to ensure that there is no detergent residue to avoid affecting subsequent use.

If the local water quality is hard or the scale in the water tank is obvious, it is recommended to perform deep cleaning once a month. You can use white vinegar or citric acid solution to soak the water tank for 30 minutes to 1 hour, soften the scale, and then gently scrub it with a soft brush. For bacterial or algae growth, you can use diluted sodium hypochlorite disinfectant or special water tank cleaner to soak for 15 minutes, and then be sure to rinse thoroughly with clean water to avoid chemical residues. In addition, check whether the float valve of the water tank is working properly to ensure that the automatic water inlet function is not affected.

Cleaning of the water tank should also include the maintenance of the filter and wet curtain. The pre-filter should be removed regularly, rinsed with clean water or cleaned with a soft brush to remove dust, and then installed after drying. If the wet curtain (cooling medium) is dusty or blocked, it can be removed and gently rinsed with clean water. Avoid rubbing vigorously to avoid damaging its fiber structure. If the stains are stubborn, you can soak it with a neutral detergent and rinse it, but be sure to rinse it completely to avoid affecting the cooling effect.

If the air cooler is not used for a long time, the water tank must be completely emptied to avoid residual moisture from breeding bacteria or producing odors. After cleaning, open the water tank cover and keep it ventilated to ensure that the interior is completely dry before storage. When storing, choose a cool and dry environment to avoid direct sunlight to prevent aging or deformation of plastic parts.

To extend the life of the water tank and maintain optimal performance, it is recommended to use purified or softened water as much as possible to reduce scale accumulation. During daily use, the water tank should be checked regularly for leaks, cracks or odors, and any problems should be dealt with promptly. If the device is running daily, it is recommended to replace the water every 2 to 3 days to keep the water fresh and avoid microbial growth. Proper cleaning and maintenance can ensure that the air cooler operates efficiently while providing healthier, fresher air.
