- Before installing the appliance, in the first place you should
prepare the system for installation. To do so, please follow the
steps described below.
IMPORTANT INFORMATION
Step 1. Unscrew the head from the cylinder. NOTE! The
distribution pipe should be embedded inside the
cylinder.
Step 3. Fill in the cylinder with quartz substrate so that it is
placed evenly on the cylinder bottom and it covers
completely the lower distributor.
NOTE! To make the cylinder filling easier, please use a
funnel.
Step 2. Cover the distribution pipe with an end cap.
NOTE! If quartz or bed gets inside the distribution pipe, it
can damage the control valve during the appliance
operation.
Step 4. Fill in the cylinder with the proper bed.
Step 5. Screw up the control valve on the cylinder.
NOTE! Earlier take off the end cap from the distribution
pipe.

INSTALLATION
- In case of high concentration of impurities in the inlet
water, we recommend the installation of a sediment filter,
ahead of the appliance.
- We strongly recommend the use of flexible hoses
to connect the appliance to the water distribution system;
use hoses with a large diameter in order to limit
the pressure loss.
- If the appliance is not equipped with the factory bypass
(optional), we strongly recommend to install a 3-valve
bypass system (not included with this product!) to isolate
the appliance from the water distribution system in case
of repairs. It allows to turn off the water to the appliance,
while maintaining (untreated) water supply to the user.

INSTALLATION
- We recommend the use of a stand pipe with air trap.
- To prevent backflow from the drainage system into
the appliance, always make sure to have an air gap
between the end of the drain line and the drainage
system itself; as a rule of thumb, the air gap should
be minimum 2x the diameter of the drain line.
- Lay-out the drain hoses in such a way that pressure
loss is minimized; avoid kinks and unnecessary
elevations.
- Make sure that the sewerage system is suitable
for the rinse water flow rate of the appliance.
DRAIN

STEP 1. Screw up the hose on the connection (1), make
sure that the hose is equipped with the stiffening insert at
its end.
STEP 2. Run the drain hose to the drainage system and
connect it to the stand pipe assuring sufficient air gap. This
drain line operates under pressure, so it may be installed
higher than the appliance.

Step 3: Setting the time regeneration - As standard the
producer set the interval between the regenerations
every 4 days. If this parameter is set as „OFF”, the
regeneration will take place in the volume mode i.e. it will
be initiated when proper amount of water in m3 has flown
through the system.
If the daily regeneration mode is set at the position „OFF”,
then the system will operate in the volume mode, but if
the time regeneration parameter is set up (range 1 - 28),
then the system will operate in the volume and time
mode.
With the buttons „+” or „-” set the daily regeneration
mode (recommended 4 days).
NOTE! Based on the observation and the result of the
water test done, the user may increase the time interval
between the regenerations. In order to adjust the
appliance as precisely as possible to the flushing cycles,
we suggest also using the readouts from the pressure
gauges installed on the water inlet and outlet from the
appliance. The difference in the values, (the pressure
drop at the second pressure gauge by 0.5 bars or more),
informs when the next regeneration of the appliance
should occur.
Press the button „NEXT” to go to the next parameter. Press
the button „REGEN” if you want to go back to the previous
parameter.
Step 2: SETTING THE LANGUAGE - the display shows that it

REGENERATION MODE
The regeneration process starts automatically, and then it
resets to the water treatment mode by itself. When the
regeneration is completed, the system starts again to
supply the installation with the treated water.
MANUAL REGENERATION: Sometimes it is necessary to
initiate the earlier cycle of regeneration. It may be related
to an intensive period of the system exploitation.
POSTPONED MODE: To initiate the regeneration manually
and define its time, you should press and release the
button „REGEN”. „REGENERATION TODAY" appears on the
screen, the system goes into the regeneration mode at the
set time (you can change the time of regeneration by
reprogramming the hour according to the steps described
previously).
If pressing the button „REGEN” causes an error display,
pressing it again will cancel the whole procedure.
INSTANT MODE: To initiate the regeneration immediately,
you should press and hold the button „REGEN”. The
system immediately goes into the regeneration mode.
NOTE! THIS PROCESS CANNOT BE CANCELLED.
In case the system is during the regeneration, it is possible
to supply the installation with untreated water. In such
situation you should set the BY-PASS valve in the BYPASS
POSITION.
MAINTENANCE
Regularly the user should perform a basic check to verify
if the appliance is functioning correctly, on the basis
of the following control points:
1. Check settings of electronic control panel.
2. Measure the contamination level before and behind
the appliance.
3. Check drain line from control valve; there
shouldn't be any water flow (unless appliance
is in regeneration).
4. Check appliance and surrounding area; there
shouldn't be any water leakages.
ROUTINE CHECKS
Occasionally it may be necessary to put the appliance
hydraulically in bypass, i.e. to isolate it from the water
distribution system; f.e.:
- in case of an urgent technical problem;
- when it is not necessary to supply treated water
to the house/application (refill swimming pool,
irrigation,...).

MAINTENANCE
The AC transformer comes with a 15 foot power cord and
is designed for use with the control valve; the transformer
should only be used in a dry location.
In the event of a power outage that is less than 24 hours,
the control valve will remember all settings and time of
day. After 24 hours, the only item that needs to be reset is
the time of day and will be indicated by the time of day
flashing. All other settings are permanently stored in the
nonvolatile memory.
If a power loss occurs that is less than 24 hours and the
time of day flashes, this indicates that the battery is
depleted. The time of day should be reset and the non-
rechargeable battery should be replaced. The battery is a 3
Volt Lithium Coin Cell type 2032 and is readily available at
most stores. To access battery location, remove front
cover.

This appliance is manufactured from premium quality
material and assembled in safe conditions to assure
it is clean and sanitary. If installed and serviced correctly,
this appliance will not infect or contaminate your water
supply. However, as in any 'device' plumbed-in in your
water distribution system, a proliferation of bacteria
is possible, especially in case of 'stagnant water'.
Therefore this appliance is equipped with a 'days override'
feature, that will automatically rinse the resin bed
periodically, even in case of low or absence of water usage.
SANITIZING THE APPLIANCE
To retain the appearance of the appliance, simply wipe
it with a damp cloth or clean it with a mild soap solution;
never use abrasive cleaners, ammonia or solvents.
