Operation Notes
If membrane system performance drops by 10% under standard conditions, or membrane fouling and scaling occur, please rinse membrane elements according to regulation process immediately.
The manufacturer won't provide warranty service, if the operating requirements and conditions aren't complied with.

Package and Transportation
The packing materials are mainly vacuum bags, foam and cartons to prevent damage in transit. Keep the storage place cool and dry without direct sunlight, keep at low temperature. In the process of transportation, avoid direct sunlight and rain, handle with care. Membrane elements should be stored in their original packaging as far as possible before use. Please follow the instructions for membrane elements.
