Storage Conditions

 

1. Before the first use, all membrane elements must be stored under the original packaging conditions.

2. Store in a cool, dry and the place where is not directly exposed to sunlight or artificial lighting. Storage temperature stays at 0℃ to 30℃, and the longest storage time is 6 months.

 

General conditions

 

· Once the membrane element is wetted, it must always be moist.

· Due to the fact that the user has not strictly complied with the operational restrictions and guidelines set by this specification, our limited warranty will be invalid.

· The system has been down for a long time to avoid the microorganism grows, we suggest putting the membrane element in the protection liquid.

· If the user USES incompatible chemicals and lubricants to cause undue influence on the original, he/she shall bear the corresponding responsibility.

· The maximum allowable pressure drop for a single pressure vessel is 60 psi (4.1bar).

· Whenever you should avoid the backpressure of the product water side, in case of adverse problems.
