Storage Condition

 

1. Before the first use, all membrane elements must be stored in their original packaging. The membrane elements are best placed in the original packaging and opened before using the water treatment system.

2. Irreversible damage to the membranes may be occurred if the transport temperature is below 0℃, and the degeneration of the membrane functions and the decomposition of the protection can be caused if the transport temperature exceeds 30℃.

3.It needs to be stored in a cool, dry and dark place. Its storage temperature is between 0℃ and 30℃, and the maximum storage period is six months.
· The maximum permitted pressure drop of every pressure vessel is psi(4.1bar).
· At no time can the backpressure be produced on the side of producing water to avoid the occurrence of problems.
