When the surrounding temperature exceeds 36°C, the cooling capacity of the air conditioner decreases, and the water does not cool. Check the temperature of the installation location and choose a well-ventilated area. Additionally, the air conditioner cools by sending water to the tank. If the pump flow rate is low, the cooling capacity of the air conditioner will decrease. Be sure to select a pump that is suitable for the air conditioner. Dirt in external filters or filtration tanks and the length of the piping can cause a decrease in flow rate. The PDF document below also introduces the calculation formulas for selecting an air conditioner. Please download it and take a look. *For more details, please refer to the PDF document or feel free to contact us.*
