PRELIMINARY INSTALLATION INSTRUCTIONS
Wall-mounted installation
The water demineralizer should be fitted in a vertical position either beneath a sink or in a cabinet. For
mounting, use the supplied dowels and screws. Install on the wall leaving a space of at least 10 cm from
the floor or the bottom surface so that the cartridge holders can be dismantled.
When the storage tank is full of
water, it weighs approximately
13kg. Check that the work surface
supports this weight.
Power Supply
The unit is supplied with 240 Vac by means of a transformer which complies with the applicable electrical
safety requirements of the Standards Institutes.
The maximum power absorbed is 40W.
Hydraulic installation
Drain Install a drain nearby to dispose the wastewater discarded by the osmotic membrane
(max 1.5m)
WB Valve The safety valve (Water Block®) is fitted with a special one-way valve which prevents the
return of water into the hydraulic system and possible consequent contamination. For
this purpose, the WB valve must be fitted in a vertical position (refer to the
instructions at the end of this manual).
Charge The installation of the product with incoming water pressure above 3 bars, can
drastically reduce the lifespan of all the cartridges and especially of the osmotic
membrane. If this is the case, the installation of a reducer to bring the pressure to less
than 3 bars is recommended.

USE AND OPERATION OF THE DEMINERALIZER
USE OF DEMINERALIZER
Once the system has been correctly installed and connected, the demineralizer is able to immediately
supply purified and demineralized water.
If the demineralized water is used to run a sterilizer, you have the option of manually filling the sterilizer
tank with the use of the water gun, or have it filled automatically by using an external filling device (e.g. Sat)
connected to the Osmo device.
The quantity of water produced by the cartridges depends on the quality and hardness of the city water
supply in the area where you live.
The average time it takes to fill the storage tank is approximately 140 minutes (with the pressure control
switch set to 3 bar).
PRECAUTIONS TO AVOID WATER CONTAMINATION
CAUTION
In accordance with subsection 4.5 of EN1717, in order to avoid water quality degradation and
bacterial growth due to a tailback of water in the tubings, the entire system must be drained
before leaving it unused for a longer period of time.
WARNING
Re-using the system after a long period of non-use
To restart the system when it hasn’t been used for a long time or after the system has been
emptied, water needs to circulate round the entire hydraulic circuit and the water collected in the
circuit needs to be drained for a few minutes ( see chapter installation, points 6-9).
It is also recommended not to leave the storage tank filled with demineralised water for a long
period of time.

REPLACEMENT OF FILTER CARTRIDGES
Only use genuine filter cartridges as they have been specifically designed for this product.
The need to replace cartridges depends largely on the operating conditions and, above all, on the quality of
the city water in your area. Annual filter cartridge replacement is recommended for average use.

Osmotic membrane
Notes:
• Using the intermediate kit maintains the life-span and performance of the osmotic membrane.
• If the water has a conductivity value of over 15 µS after the intermediate kit has been replaced, also
replace the osmotic membrane
• All the cartridges can vary slightly, which in combination with unfavourable operational conditions (e.g.
high temperature, high presence of chemical particles in the water supply, high pressure) can cause a
high reduction in the performance of the product.
• In the event of unexpected contamination of the water coming into the system (for example the
presence of soil), all the cartridges can get damaged. Replace the intermediate kit and check if the
osmotic membrane also needs changing.
• The installation of the product with incoming water pressure above 3 bars, can drastically reduce the
lifespan of all the cartridges and especially of the osmotic membrane. If this is the case, the
installation of a reducer to bring the pressure to less than 3 bars is suggested.
To replace cartridges follow these steps:
1. Disconnect the power supply
2. Close the tap water inlet valve and the storage tank valve
3. Release the water pressure with the use of the water gun (or tap, if connected) and/or disconnect the
tubing leading to an external automatic filling device (e.g. Sat).
4. Unscrew the cartridge holder counter-clockwise with the use of
the supplied special tool.
5. Remove used cartridges, remove and clean the centring
rings, replace the cartridges using the rings. Make sure to

REPLACEMENT OF THE OSMOTIC MEMBRANE
The service life of an osmotic membrane is normally over 2 years (depending on the quality of the city
water in your area) but the use in unsuitable conditions can drastically reduce this.
In order to replace the membrane, first unplug the power supply and close the water inlet and the storage
tank valve. Proceed as shown in the images below.

MAINTENANCE
EXTERNAL CLEANING
Clean with a damp cloth using non-abrasive and non-corrosive detergents (neutral pH value).
MAINTENANCE OF THE WATER BLOCK® AND ONE-WAY VALVE
Depending on the city water quality in your area and the frequency of use of the equipment, the valve inlet
filter should be regularly cleaned as explained in the instruction leaflet attached to the end of this manual.
CAUTION
Regular control of the Water Block and one-way valve
To ensure compliance with subsection 4.6 of EN1717, have the Water Block and the one-way
valve checked at least once a year; in case a sterilizer is attached to the system, this could be
done during the scheduled maintenance visits for the sterilizer.
It is further recommended to check all related devices fitted to the sterilizer to ensure that the
hydraulic connection between demineralizer and sterilizer corresponds to category 2, in
accordance with EN 1717.
WARNING
The Water Block serves as an anti-flooding device. Blocking only takes place if there is
considerable leakage (such as a cut in the tube between the Water Block and the demineralizer).
Blocking does not take place if there is a small leak in the product’s hydraulic system.

MAINTENANCE ISTRUCTIONS FOR THE SAFETY VALVE
(WATER BLOCK®)
WATER BLOCK (WB) SAFETY VALVE
Indispensable device for washing machines, dishwashers and demineralizers as, under the conditions defined in the technical
features herewith described, it prevents a flow of water greater than the one for which it has been set by the adjustment
pointer. This avoids continuous leaking. The Water Block also has a particular non-return valve (antipollution). The device
should be installed vertically (see fig. 2) and following the instructions carefully.
TECHNICAL FEATURES
-
Burst pressure: 500 N/cm²
-
Max. static pressure: 100 N/cm²
-
Max. controllable volume: about 50 lt.
-
Min. operating capacity: 2 lt/min.
-
Max. operating capacity: 30 lt/min
-
Max. water temperature: 70° C
USER INSTRUCTIONS
WATER BLOCK should be installed between the tap and the supply hose of the
demineralizer (fig. 2). Using the enclosed plastic key, turn pointer ‘P’ (fig. 1)
anticlockwise to the required setting (example, position 1,5).
CAUTION:
For use on other fixtures, set the pointer to a position suitable for that particular application, considering that each number on
the scale corresponds to a controlled volume of approx. 4-6 litres.
In case of installation on fixtures which foresee dispensing of drinking water for alimentary use it is advisable to let flow at least
10 litres of water inside the device before the connection, so as remove eventual impurities banked during the storage.
INSTALLATION
1. Manually screw the WB to the tap having suitable thread (3/4” gas),
inserting the filter ‘E’ with its convex side facing upwards (fig. 2). The
WB will not operate properly if the filter is not installed correctly. If the
WB is tightened or loosened with the aid of a wrench, the same must
be applied to the appropriately octagonally shaped part of the housing
‘A’.
2. Screw the supply hose ‘C’ to the lower end of the WB. If the supply
hose is equipped with a filter, the latter must be substituted by a flat
rubber washer ‘F’. If the said hose has to be tightened or loosened with
the aid of a wrench, the same must be applied to the appropriately
octagonally shaped part of the WB housing ‘B’ so as to hold it firmly
while performing this operation.
If a failure occurs causing a continuous water leak, the WB will shut off
when the volume of water flowing through equals the amount to which it
was previously set with the pointer ‘P’.
To reset the Water Block again after it has shut off, turn the tap off and
carry out the necessary repair work. Remove the supply hose ‘C’ from
the Water Block and press the coloured plunger ‘H’ which is located
inside the lower housing of the device itself (fig. 1). It may be difficult to
press this plunger if there is high pressure at the inlet side of the WB. In
this case, slacken the device from the tap: the plunger ‘H’ can then be
pressed with ease. Repeat the operation as described in the section
headed ‘Installation’.
CAUTION:
To avoid any possible damage that may be caused by water freezing inside
the WB after its installation, the ambient temperature should never be below
2° C. We decline all responsibility deriving from th e incorrect use of the WB
or from its use for applications and/or solutions not expressly foreseen by the
above instructions.
MAINTENANCE:
Depending on the conditions and frequency of usage of the water block, it is recommended to
clean out the inlet filter ‘E’ periodically and to replace the seal ‘F’ .We reserve the right to modify any
features without prior notice.
