PREPARATION BRINE CABINET
Picture 1&11
To facilitate the installation, you may want to remove the salt
lid and main cover from the brine cabinet.
1. Remove the salt lid.
2. Unscrew the screw rivets at the front of the main cover.
3. Carefully lift the main cover from the water softener.
CASTER WHEELS (optional on micro & mini only)
In case the water softener is delivered with the optional
caster wheel set, it needs to be mounted on the cabinet upon
installation of the water softener.
Picture 2
1. Position the reinforcement plate on the bottom of the
water softeners cabinet, making sure the 4 holes in the
reinforcement plate align properly with the 4 threaded
sockets in the cabinet.
2. Screw the 4 caster wheels into the threaded sockets;
make sure to install the washers. Tighten firmly. Make
sure the 2 caster wheels with brake are easily accessible.
INLET & OUTLET
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.
The inlet/outlet adaptors are equipped with an
integrated non-return valve, to prevent any kind of backflow
into the water softener or mains water supply; make sure to
install them in the correct flow direction!
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.
WITH FACTORY BYPASS (optional)
Picture 3
= mains water supply (untreated water)

3. Connect the 3-valve bypass system to the adaptors on the
in () and out () elbow connections.
4. Connect the mains water supply to the inlet of the 3-valve
bypass system.
5. Connect the application to the outlet of the 3-valve
bypass system.
DRAIN
We recommend the use of a stand pipe with P-trap.
To prevent backflow from the sewerage system into the
appliance, always install and use the included drain adaptor
with air gap and double hose barb, to connect the drain
hoses to the sewerage system.
Always use separate drain hoses for the control valve
(discharge of rinse water) and the brine cabinet's overflow.
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.
Picture 5
1. Install the drain adaptor to the sewerage system; it fits
over a 32 mm pipe or inside a 40 mm pipe adaptor. Ensure
a permanent and watertight connection.
2. Connect a 13 mm hose to the drain solenoid of the control
valve (); secure it by means of a clamp.
3. Run the drain hose to the drain adaptor and connect it to
one of the hose barbs; secure it by means of a clamp. This
drain line operates under pressure, so it may be installed
higher than the appliance.
4. Connect a 13 mm hose to the brine cabinet overflow
elbow; secure it by means of a clamp.
5. Run the drain hose to the drain adaptor and connect it to
the other hose barb; secure it by means of a clamp. This
drain line does NOT operate under pressure, so it may
NOT be installed higher than the appliance.

PRESSURIZING
1. Make sure the bypass system is in 'bypass' position.
2. Make sure the electronic controller of the appliance is in
service mode.
3. Open the mains water supply.
4. Open a cold treated water faucet nearby the appliance
and let the water run for a few minutes until all air is
purged and all foreign material that may have resulted
from the installation is washed out; close the tap.
5. Gently pressurize the appliance, by putting it into service:
factory bypass:
1. open the 'outlet' valve;
2. slowly open the 'inlet' valve.
3-valve bypass:
1. close the 'bypass' valve;
2. open the 'outlet' valve;
3. slowly open the 'inlet' valve.
6. After 2-3 minutes, open a cold treated water faucet
nearby the appliance and let the water run for a few
minutes until all air is purged from the installation and the
resin bed is rinsed (it is normal for the rinse water to show
some discoloration!); close the tap.
7. Check the appliance and all hydraulic connections for
leaks.
After the first regenerations of the appliance, some
slight discoloration of the treated water might occur. This is
totally harmless and will disappear rapidly!
BRINE CABINET
1. Add water conditioner salt to the brine cabinet.
ELECTRONIC CONTROL PANEL
1. Program the electronic controller.
ADJUSTMENT RESIDUAL HARDNESS
WITH FACTORY BYPASS (optional)
In practice the residual hardness is influenced by the
inlet pressure, flow rate and hardness of the incoming
untreated water. When adjusting the residual hardness,
make sure these conditions are similar to the actual
operating conditions.
Picture 7
1. Adjust the residual hardness of the water that leaves the
appliance, by means of the adjusting screw, incorporated
in the ‘outlet’ valve of the factory bypass:
to raise the residual hardness: turn the screw counter

RECOMMENDATION
Notwithstanding the reliability of the appliance, we strongly
recommend to have it serviced and maintained on a regular
basis by a competent and duly trained technician. He will be
able to determine the appropriate maintenance interval for
the appliance, depending on your specific application and the
local operating conditions. The advantages of performing
regular maintenance are:
regular check of the local operating conditions (water
quality, pressure, etc);
regular control and adjustment of the settings of the
appliance, to guarantee it operates at maximum
efficiency;
minimize the risk of unexpected break-down.
Contact your dealer or installer for more information, or visit
our website.
ROUTINE CHECKS
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 water hardness before/after appliance.
3. Check drain line from control valve; there shouldn’t be
any water flow (unless appliance is in regeneration).
4. Check drain line from brine cabinet overflow; there
shouldn’t be any water flow.
5. Check appliance and surrounding area; there shouldn’t be
any water leakages.
BYPASSING THE APPLIANCE
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,...).

WATER CONDITIONER SALT
Picture 11
The appliance needs 'brine' for its periodic regenerations. This
brine solution is made from water, that is automatically dosed
in the brine cabinet by the control valve, and water
conditioner salt. The user should make sure that the brine
cabinet is always kept full of water conditioner salt. Therefore
he should periodically check the salt level inside the brine
cabinet and refill it if necessary. The salt lid can be removed
completely to facilitate refilling.
Ideally the level of water conditioner salt inside the brine
cabinet is kept between 1/3 and 2/3. A lower level of water
conditioner salt can cause insufficient brine saturation,
resulting in a loss of softening capacity. A higher level of water
conditioner salt can cause salt bridging (hard crust or salt
bridges in the brine cabinet). When you suspect salt bridging:
carefully pound on the outside of the brine cabinet to
break loose the salt bridges;
using a broom (or like blunt tool) carefully push the salt to
break it apart;
pour warm water over the top of the salt to dissolve it.
APPEARANCE
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.
RESIN CLEANER
Other contaminants (f.e. iron) present in the feed water can
cause the resin bed to foul up, resulting in a loss of softening
capacity. An approved resin cleaner can be used periodically
to thoroughly clean the resin bed.
Page 12
MAINTENANCE
Page 12
SANITIZING THE APPLIANCE
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.
If the power supply to the appliance is disconnected for a
longer period of time, we recommend, when the power
supply is re-established, to manually initiate a complete
regeneration.
