General conditions of use

1. The storage location must be cool (not higher than 45°C) and dry without direct sunlight.

2. For initial commissioning and initial operation of the reverse osmosis membrane element, the pure and concentrated water should be discharged within the first hour after start-up.

3. Once the dry membrane element is wet, it should always be kept moist.

4.To prevent microbial growth in wet membrane elements, it is recommended that the elements are soaked in a protective solution containing 1.0% sodium metabisulphite (food grade) and then vacuum packed in a cardboard box.

5. It is forbidden to add any chemicals that may affect the membrane element and Yoxing Water Purification will not be held responsible for any consequences arising from the use of such chemicals.
