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 drop across an entire pressure vessel (housing) is 30 psi / 2.1 bar.
• Avoid static permeate side back pressure 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 pre-treat-
ment 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 sup-
plier for more information. If operating limits and guidelines given in this product specifica-
tion 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 mem-
branes 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 op-
eration and maintenance of the system.
No freedom from infringement of any patent owned by the manufacturer or others is to be

other and may change with time, customer is responsible for determining whether prod-
