PURON modules should be stored within a temperature range of 41 to 77^oF (5 to 25^oC) in the original packaging material. Extended exposure to UV source must be avoided. The PURON® modules must not be stored for longer than 3 months after delivery.

During transport, PURON® modules should be stored within a temperature range of 23 to 113^oF (-5 to 45^oC), but they should not be kept at temperature outside the normal storage range of 41 to 77^oF (5 to 25^oC) for more than 6 weeks.

When the PURON® modules are being transported by ship, the PURON® module should be placed in seaworthy packaging and stored at ambient temperature, provided that such temperature is within the temperature range specified herein.

Once the PURON® module has been immersed in an aqueous medium, it should never be stored dry. If the membrane plant is not operated for 7 days or less, the module may be kept wet by keeping it submerged in the biomass, provided the following conditions are met During transport, PURON® modules should be stored within a temperature range of 23 to 113°F (-5 to 45°C), but they should not be kept at temperature outside the normal storage range of 41 to 77^oF (5 to 25^oC) for more than 6 weeks.

If the shutdown period is longer than 7 days, immersion in a storage solution is required. Please consult KSS for more information.

If used PURON® modules are permitted to dry out, membrane performance, such as permeability, may be adversely affected. Please consult KSS to see what steps may be taken to try to reverse such negative effects.

Utmost care should be taken at all times when handling the PURON® module. Collisions, impact or hitting the ground in a rough manner may damage modules or connections.

Keep the PURON® modules free from contact with sharp or abrasive objects or exposure to heat sources. Actions that may cause sparks (e.g. welding, grinding) should be strictly prohibited in the vicinity of the modules.
