Note: Discard the first produced permeate during the first
10 minutes after any new installation/first commissioning or
at any membrane replacement.
Note: Please run the RO unit a few days to reach the
full performance (WCF and permeate quality).
Note: A drop of temperature by 1°C will reduce the
permeate output of the membranes by approx. 3.0%.
