Preliminary water treatment block (2, 3) includes replacement filter cartridge K5 (3) and K2
(2). The preliminary water treatment block removes any impurities that can damage membrane cartridge,
such as ferric hydroxide and active chlorine.
Reverse Osmosis membrane block (4) includes the replacement membrane cartridge
Aquaphor RO-50S (for RO-101S) or RO-100S (for RO-102S) and purifies water by removing organic
compounds, non-organic compounds, and salts while softening water.
Water conditioning block (5) includes the mineralizing cartridge K7M. The water conditioning
block eliminates unwanted odors and flavors from water while mineralizing the water.
Attention!
The mineralizing cartridge K7M can be replaced with the K7 cartridge.
How RO works
The water coming from the cold water
mains enters RO and passes through the pre-
liminary 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 out-
lets: the treated water outlet and the drain
water outlet. On its way to the drain, the wa-
ter 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 drinking water, while the techni-
cal chamber contains water from the mains.
As clear water collects, water from the mains
is forced from the technical 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.
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.
