* If pressure of water in your system does not meet requirement, install a pressure booster pump to raise it.
If water pressure exceeds the upper limit, install a pressure regulator before the Robust system.
** Using the Robust system with feed water temperature between +20 and +30 °С produces a lower
rejection rate and higher flow rate, which yields higher TDS of purified water. Using the system with feed
water above +30 °С is advised against.

* If feed water quality does not meet specified requirements, membrane and filter service life may decrease.
** If aiming to purify raw water (well water/ground water etc), it is recommended to carry out detailed
water analysis. If any constituents exceed the above limitations, it is advisable to install a special filter
upstream of your reverse osmosis system. Consult professional water treatment specialist for proper
selection of an appropriate filter for your water.
