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 makers and ice makers 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 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
(fig. 1) The main components of the water softener are:
- 1 tank containing the resins for water softening

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 checking 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 that can be 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 safety norms or personal safety norms 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 hydric pressure is over 8 bar, it is necessary to install a pressure adaptor.
-
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 SYSTEM (fig.1)
The connection of the equipment to the water system must be done according to all applicable norms, following the instructions of the manufacturer and qualified personnel. During the installation use pipes, hoses, valves and components which comply with the applicable Italian norm 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 which hygienic safety was compromised, as they could corrupt the quality of treated water and the equipment itself. Connect the water inlet (fig. 1, A) and outlet (fig.1, B) to the connection joints (fig.3) of the water softener, tightening them safely
Ensure that:
- The water inlet and outlet pipes (fig. 1, A and B) comply with the norms on drinking water pipes.
- The water inlet pipe (fig 1, A) has an internal diameter of at least 7 mm.
- A standard tap (fig. 1, M) 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.
- Install on the water outlet a check valve (fig. 1, I) (DVGW, DIN 1988 T2) to protect the water softener from a reverse flow of hot water that could cause damage.
- Install a tap to take a sample of the outlet water, 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 funneled into the floor sink by
the flexible pipe (fig.1, F) included in the package.
Warning: keep the drain pipe suspended over and not immersed in the water
of the sink (fig. 1, N).
At the end of the installation, before opening the water inlet and outlet
taps (fig. 1, C-D), 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 (fig. 2)
Put the water outlet pipe in the floor sink. Turn the tap levers on the left and open the standard tap to let the water in. Let the water flow until it is clear, then close the standard tap (fig.1, M) and connect the water outlet pipe to the machine of your choice.
4.2 PERIODIC REGENERATION (fig. 4)
• Position B (DEPRESSURIZATION MODE)
- Put the depressurization pipe in a bucket (fig. 1, E and fig. 4, position B)
- Turn the tap levers on the right and wait until depressurization.
- Remove the lid (fig. 1, G) and add the required quantity of Instruction
Manual Water Softener salt according to the model (see the table at paragraph
2.6)
• Position C (CLEANING)
Clean the lid and the seal (fig. 4, C) from any salt residue. Clean the upper part of the water softener from any salt residue and clean 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 and tighten it.
• Position D (RINSING MODE) - Turn the water inlet tap lever (fig. 1, C) on the left
- Let the salt water come out from the drain pipe until the water is fresh
(around 40 minutes)
• Position A (SERVICE MODE) - Put the water softener back in service mode by turning the water outlet tap
lever back on the left (fig.1, D)
WARNING: during the regeneration, the machine connected to the water softener does not receive drinking water.
5. MAINTENANCE FOR THE INSTALLER:
5.1 CHANGING THE RESINS
The resins’ softening capacity ends after 5-7 years. This period can change 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 change the water softener itself. To change the resins it is necessary to disconnect the water softener and bring it to an appropriate place. To disconnect the water softener:
-
- Close the main water inlet tap (fig. 1, M)
-
- Put the depressurization pipe in a bucket (fig. 1, E and fig. 4, Position B).
-
- Turn the tap levers on the right, as in fig. 4, Position B.
-
- Wait a few seconds until depressurization.
-
- When water stops coming out of the depressurization pipe (fig. 1, E) it is possible to unscrew the inlet and outlet pipes (fig. 1, A and B) from the joints (fig. 3).
-
- Open the lid (fig. 1, G) and change the resins. Clean the interior of the tank before inserting the new resins.
Do not throw the exhausted 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.
- Open the lid (fig. 1, G) and change the resins. Clean the interior of the tank before inserting the new resins.
-
- Close the lid (fig. 1, G) and bring the softener back to its installation place.
-
- Connect the water inlet and outlet pipes to the joints (fig. 3) and tighten them.
-
- Rinse the resins as explained in paragraph 4.1.
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 (fig. 1, G) 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.
