FOR THE INSTALLER
We suggest to install the equipment after carefully reading the instruction manual. Should complications arise, we
suggest asking your seller for assistance. The seller’s information is written on the last page of this manual.
FOR THE USER
• Never try to repair the equipment by yourself: you may cause damage. Ask your seller for assistance.
• For manual regeneration and regular salt refillings, read the “ACTIVATION AND INSTRUCTIONS FOR
REGENERATION”.
• Cleaning the water softener is part of the user’s duties. The manufacturers are not responsible for any damage
or harm that may derive by not following these precautions.
2. ABOUT THE EQUIPMENT
2.1 HOW DOES IT WORK?
The cationic resins in the softener’s tank transform calcium carbonate in sodium carbonate which is water-soluble
at the working temperatures of both coffee and ice machines. The transfer of sodium ions between the resins and
water is imperative to soften drinking water, but this process tends to decline in proportion to the flow rate and
to the consumption of water. For this reason, it is necessary to regenerate the exhausted resins by making water
and salt flow through them, therefore returning them to their active state. The resins gradually lose their cationic
function, and consequently their efficiency, with each regeneration. We recommend replacing them after seven
years of use.
2.2 EQUIPMENT DESCRIPTION
Main components of the water softener are:
• 1 IV valve allowing use of water even during resins regeneration

3. INSTALLATION
3.1 PACKAGING
• Before the installation, check that the equipment was not damaged by the transport and does not show any
anomaly. In case of doubt, ask your seller.
• Don’t throw the package away for some time, being careful to keep any dangerous or small parts of the package
away from children.
3.2 CHOOSING THE PLACE OF INSTALLATION
• Ensure that any other water treatment machine is not present upline of the place of installation.
• Ensure that feed water comes from a drinking water pipe. We recommend to check the chemical and physical
parameters of the drinking water as well as its hardness before installation.
• Install the equipment near a floor sink to dispose of the waste water produced by the regeneration.
• Install the equipment in a dry place easily accessible to maintain, regenerate and clean the equipment.
Do not install the equipment in dirty and unhygienic places or in any place difficult to clean.
• Ensure that room temperature in the place of installation is between 4°C and 35°C.
• Keep away from corrosive or acid products.
• Do not install in places where electric or personal safety regulations are openly disregarded.
• Hydric pressure must not be under 0.1 Mpa (1 bar) or over 0.8 Mpa (8 bar). (We recommend at least 3 or 4 bar)
• If water pressure is over 8 bar, it will be necessary to install a pressure regulator.
• Salt packages or boxes must not be kept in humid places or in direct contact with the floor: keep it, for example,
on a wooden pallet.

3.3 CONNECTION TO THE WATER NETWORK (pic. 2)
The connection of the equipment to the water system must be done according to all applicable rules, following
the instructions of the manufacturer and qualified personnel. During the installation use pipes, hoses, valves and
components which comply with the applicable Italian rule on hygienic safety, the Ministerial Decree 174/2004.
They must be kept in their sealed package until the moment of installation to preserve their hygienic safety. It is
forbidden to use components that are not suitable for drinking water contact or components whose hygienic
safety was compromised, as they could corrupt the quality of treated water and the equipment itself. Check if
there are hygienic safety taps on the input and output of the equipment. Remove them only during this phase
and not before.
3.3.1 QUICK JOINTS
The pipes are connected to the valve by quick joints.
Connect the water inlet (A) and outlet (B) pipes to
the joints in the package, tightening them safely.
To connect the joint to the valve it is necessary to
insert it all the way in. The metal inserts of the quick
joint will prevent the pipe from disconnecting.
To remove the pipe it is necessary to depressurize
the tank, then press on the black ring that surrounds
the pipe next to the insertion and extract the pipe.
Ensure that:
• The water inlet and outlet pipes comply with the
regulations on drinking water pipes.
• A water inlet tap (C) must be installed by the user
between the water system and the water softener to ensure that water flow can be interrupted in case of
necessity.
• It is advisable to install a one-way valve (H) on the outlet to avoid unwanted refluxes.
• Install a tap to take a sample of the outlet water in order to test its hardness. All pipes must be free, not crushed
or constricted.
3.4 CONNECTION TO THE DRAIN SYSTEM
Waste water resulting from the regeneration is funnelled into the floor sink by the flexible pipe (pic. 1, E) included
in the package.
Warning: keep the drain pipe suspended over and not immersed in the water of the sink (pic. 1, L). At the end of
the installation, before opening the water inlet tap (pic. 1, C), rinse the resins as explained in the chapter
“ACTIVATION AND INSTRUCTIONS FOR THE REGENERATION”.
4. ACTIVATION AND INSTRUCTIONS FOR THE REGENERATION
4.1 RINSING THE RESINS
Turn the valve handle on number 4, backwash mode. Open the water inlet tap and let the water flow through the
flexible pipe (E) until it is clean. Turn the handle back on number 1.

4.2 PERIODIC REGENERATION
Position 2 (DEPRESSURIZATION MODE
)
- Turn the valve handle on number 2. Loosen the cover handle and wait
until depressurization.
- Remove the lid and add the required quantity of salt according to the
model (1.0 kg)
Cleaning
Clean the lid and the seal from any salt residue.
Clean the upper part of the water softener from any salt residue and
clean both the tank and under the cover of the weld joint of any leaked
salt water.
The manufacturer does not take responsibility for the corrosion of the
tank caused by the failure to follow these instructions.
- Put the lid back on (pic. 1, G) and tighten the cover handle (pic. 1, F)
safely.
Po
sition 3 (RINSING MODE)
- Turn the valve handle on number 3.
- Let the salt water come out from the drain pipe until the water is fresh
(around 40 minutes)
Position 4 (BACKWASH CLEANING MODE)
- Turn the valve handle on number 4 and wait for 30 seconds
(during the backwash mode, the water softener does not supply water)
Position 1 (SERVICE MODE)
- Put the valve handle back on number 1, service mode.
WARNING: during regeneration, the machine connected to the water
softener is supplied with non-softened water.

4.3 MIXER CONTROL
The regulator (REG.) has a special screw. By gradually loosening the
screw, the equipment leaves a residue of hard- ness in the exiting
water. The more you loosen the screw, the more hardness it leaves.
This operation must be performed with care. At the end of the
operation, it is necessary to check the hardness levels.
Attention: the hardness levels in water must be periodically checked by
the installer.
5. MAINTENANCE FOR THE INSTALLER:
5.1 CHANGING THE RESINS
The resins’ softening capacity ends after 5-7 years. This period can vary based on the characteristic of the feed
water and the quantity of softened water. After this period of time, the user needs to decide if it is enough to
change the resins or if it is better to replace the water softener itself.
To change the resins it is necessary to turn the valve handle on number 2 (pic. 3). Wait a few seconds until tank
depressurization. When water stops coming out of the drain, move the plastic blocks outwards (pic. 3, A). It will
then be possible to separate the valve from the tank (pic. 3, B) Bring the tank to an appropriate place to change
the resins and clean the interior of the tank. Open the lid and change the resins.
Do not throw the resins in the sewers. The resins are not biodegradable and must be considered a non-hazardous
waste (EU code CER 190905).
After changing the resins, clean the lid seal and the upper part of the softener from any resin residue. Close the lid
and connect the valve to the tank. Close the blocks and turn the handle on number 4. Let the water flow from the
drain pipe until it is clean.
Turn the handle back on number 1.

5.2 RESIN PRESERVATION AND ACTIVATION AFTER A LONG PERIOD OF INACTIVITY
If the water softener is not to be used for more than 30 days, it is necessary to do a double regeneration first and
then leave the water softener with the lid closed. We suggest avoiding a period of inactivity longer than 12
months. It is forbidden to reactivate the system after this period of inactivity. If the period of inactivity is shorter
than 12 months, it is necessary to rinse the resins and do a manual regeneration (paragraph 4.1 and 4.2) before
reactivating the equipment.
6. IMPROPER USE OF THE EQUIPMENT
This equipment has been designed to soften drinking water for domestic and technological use. The equipment
must not be used for any different purpose and it must not be modified or tampered with in any way. Any other
use than the one specified in this manual is improper and therefore dangerous. The manufacturer cannot be
considered responsible for any damage caused by improper, mistaken or illogical use of the equipment.
• It is forbidden to feed the equipment with any liquid other than drinking water.
• It is forbidden to introduce in the tank any products other than salt (NaCl).
7. EQUIPMENT DISPOSAL
Any waste must be disposed of according to the applicable regulations. The water softener was
built with non-hazardous materials like polymers and stainless steel, and they must be disposed of
according to the applicable rules. Do not throw the resins in the sewer. The resins are not
biodegradable. They are classified as non-hazardous waste and must be disposed of accordingly (EU
code CER 190905)
