Warranty Evaluation Test Conditions: Permeate flow and salt rejection based on the following test conditions
– 550 ppm, filtered and dechlorinated municipal tap water, 77°F / 25°C, 15% recovery
and the specified operating pressure. Minimum salt rejection is 96%. Permeate flows for warranty evaluation may vary +/-20%. Maximum pressure drops at 13 psi / 0.9 bar.

Proper start
–up of reverse osmosis water treatment systems is essential to prepare the membranes for operating service and to prevent membrane damage due to
overfeeding or hydraulic shock. Before initiating system start
–up procedures, membrane pretreatment, loading of the membrane elements, instrument calibration
and other system checks should be completed.
Avoid any abrupt pressure or cross
–flow variations on the spiral elements during start–up, shutdown, cleaning or other sequences to prevent possible membrane
damage. During start
–up, a gradual change from a standstill to operating state is recommended as follows:
▪
Feed pressure should be increased gradually over a 30
– 60 second time frame.
▪
Cross
–flow velocity at set operating point should be achieved gradually over 15 – 20 seconds.
▪
Permeate obtained from first hour of operation should be discarded.
▪
Maximum pressure drops across an entire pressure vessel (housing) is 30 psi / 2.1 bar.
▪
Avoid static permeate
–side backpressure at all times.
Under certain conditions, the presence of free chlorine, chloramines and other oxidizing agents will cause premature membrane failure. Since oxidation damage is
not covered under warranty, the manufacturer recommends removing all oxidizing agents by pretreatment prior to membrane exposure. Please contact the
manufacturer or your supplier for more information.
Do not use this initial permeate for drinking water or food preparation. Keep elements moist at all times after initial wetting. To prevent biological growth during
prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative before use. For
membrane warranty details, please contact the manufacturer or your supplier for more information.
If operating limits and guidelines given in this product specification sheet are not strictly followed, the warranty will be null and void. The customer is fully responsible
for the effects of incompatible chemicals and lubricants on elements. Use of any such chemicals or lubricants will void the warranty. These membranes may be
subject to drinking water application restrictions in some countries: please check the application status before use and sale. The use of this product in and of itself
does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design
and on the operation and maintenance of the system.
