Step 4. Flushing the reverse osmosis
membrane unit
• Remove the service plug from the slot of the
reverse osmosis membrane unit and replace it
with the membrane cartridge as shown in Fig. 14.
• Turn the inlet cock of the connecting assembly
to its open position. The cartridge life indicator
lights blink (the light signal is followed by an
audible signal).
• Make sure the RO-206S connections are tight.
Attention! If leaks are found, immediately turn
the inlet cock of the connecting assembly to its
closed position and check the connections. Turn
the inlet cock of the connecting assembly to its
open position again to continue the flushing
procedure after the leak is repaired.
• Wait for the water to flow from the tap for treated
water.
• Let the water through your RO-206S for 1 hour.*
• Close the treated water tap.
• Fill and empty the storage tank 2 more times.
• Press and hold the PUSH button for at least
7 seconds. The cartridge life light indication
changes from the flashing mode to the constant
one, and the audio signal stops.
• Make sure the RO-206S connections are tight.
• Your RO-206S is ready for use once the tank
is filled.
ATTENTION! The water is not intended for drink-
ing after flushing.
Periodically check your RO-206S for leaks during
the first week of use. Some noise may occur
during the first week of operation of your RO-
206S when switching the valve because of air
released from the internal cavities of the system.
This is not a malfunction.
7. Replacing Cartridges
Your RO-206S is equipped with a light and sound
indication of cartridge life.
The RO-206S light and sound indication is
configured to work with cold drinking water
from municipal water supply systems that meet
sanitary standards.
Each of the filtration units has an individual light
indication (Fig. 15): indicators 1 and 4 correspond
to cartridges K1 and K2 of the water pre-treatment

portation conditions.
unit, indicators 2 and 3 correspond to the reverse
osmosis membrane unit.
The flashing indicators of the filtration units
,
followed by a periodic sound signal, inform about the
expired service life of the corresponding cartridge.
In this case, the cartridge must be replaced with
a new one.
