Simply fill the chiller with clear vinegar, leave for 24 hours and then rinse it with water. Make sure to also place an air circulation fan near the chiller to avoid heat build-up. Please note: The flow rate is determined according to the maximum flow of the pump (submersible pump or other external feed filter) and the circulation equipment. The cooling performance test is shown when the ambient temperature is 30°C , the water temperature before cooling is 28°C , the set temperature is 16°C , and the chilled water is no more than 250 liters . When the water cooling is reduced, the water temperature will drop. The cooling efficiency is determined by the installation location, heating source, lighting, pump filter and other connecting parts. Special pumps and other accessories sold with Hailea series chillers must be used. Do not use other alternatives to avoid affecting the performance of the unit. When there is not enough air exchange in a room, cooling efficiency is reduced if the ambient temperature rises due to heat from the module.
