Permeate from the first hour of operation should be discarded. Do not use this initial permeate for consumption.
To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution. Rinse out the preservative solution before use. 
Elements contained in the boxes must be kept dry at room temperature (5–35°C / 41–95°F) and should not be stored in
direct sunlight.
Keep elements moist at all times after initial wetting. 
The presence of free chlorine and other oxidizing agents can cause premature membrane failure. Since oxidation damage
is not covered under warranty, Aquaporin A/S recommends removing residual free chlorine by pretreatment prior to
membrane exposure.
