1. Mount the security valve (Water Block®) to the tap water connection.
2. Connect the water inlet tube to the security valve and the demineralizer.
3. Connect the spiral tube to the front of the demineralizer.
WARNING
Use only original spare parts.
The Water Block® valve is fitted with a special one-way valve that prevents water from flowing back
and potentially polluting the main waterline.
For this reason the Water Block valve should be mounted vertically.

INSTRUMENTS
REPLACEMENT OF THE RESIN CARTRIDGES
When used with a sterilizer, replace the resin cartridges when the water conductivity reaches a value of 15
μS. Most sterilizers generate a display message once the water quality drops below a certain threshold.
1. Close the water supply tap at the front of the DEMI-One base.
2. Release the internal water pressure with the water gun.
3. Follow the steps as described in chapter “Mounting of the resin cartridges”.
4. Open the water supply tap.
PRECAUTIONS TO AVOID WATER CONTAMINATION
ATTENTION
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 tubes, the
entire system must be drained before leaving it unused for a longer period of
time.
OPERATION OF THE DEMINERALIZER
Once installed and fitted correctly, the demineralizer is able to supply demineralized
water immediately.
ATTENTION
The demineralizer is equipped with a Water Block® valve that cuts off the water flow after a pre adjusted volume (5 liters) in order to prevent a large spillage of water in case of a broken tube.
When you take water from the demineralizer with the use of the spray gun and the volume goes
beyond 5 liters, the Water Block® valve will cut off the water supply. To reset the Water Block® valve
see hapter “Maintenance instructions for the safety valve”. To avoid a water cutoff, release the water
gun once every 30 seconds if quantities of more than 5 liters are taken from the demineralizer.
The quantity of demineralized water produced per set of resin cartridges depends on the quality and
hardness of the city water in your area. Refer to the table below for further details:

MAINTENANCE
EXTERNAL CLEANING
Clean with a damp cloth using non-abrasive and non-corrosive detergents (neutral pH value).
MAINTENANCE OF THE WATER BLOCK® SAFETY VALVE
The inlet filter of the Water Block® valve should be cleaned on a regular basis, depending on the city water
quality and how often the demineralizer is used.
REGULAR CHECK OF THE WATER BLOCK® AND ONE-WAY VALVES
ATTENTION
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 steriliser to ensure that the
hydraulic connection between demineralizer and sterilizer corresponds to category 2, in accordance
with EN 1717.

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 the 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.
