When the clean water faucet is opened, water
from the mains enters the technical chamber
via the shutoff valve and forces treated water
from the storage chamber through the faucet
via the conditioning block. The automatic check
valve then triggers and opens water supply to
the RO-storage tank.
5. RO installation
ATTENTION!
Only install your RO by a qualified
plumber who is certified to perform the instal-
lation in accordance with state law.
Locate the appropriate installation place for the
faucet and RO. Take care to ensure that the de-
livery tubes are pulled freely, without over bend-
ing. RO must be installed on a flat, even solid
surface as installation on an uneven surface may
cause vibration or noise. Additionally, RO must
be located away from heat sources, such as
kitchen ovens, hot water supply pipes, dishwash-
ers or washing machines, or at least isolated
from such heat sources.

How RO works
The water coming from the cold water mains
enters RO and passes through the preliminary
water treatment block. From there, water enters
the Reverse Osmosis membrane block via the
automatic check valve. The unit housing the
membrane cartridge has two outlets: the treated
water outlet and the drain water outlet. On its
way to the drain, the water will also pass through
a flow restrictor. The flow restrictor flushes the
drain water that goes down the drain.
The treated water enters the storage tank that
has a built-in membrane. This separates the tank
into two chambers: storage and technical. The
storage chamber contains the fully purified drink-
ing water, while the technical chamber contains
water from the mains. As clear water collects,
water from the mains is forced from the techni-
cal chamber into the drain, also preventing the
accumulation of clear water. When the storage
tank is full, the automatic check valve cuts off
the water intake into RO.
