DEMI5® Warranty?
3 YEARS
What is covered by the warranty?
All the defects of the materials and the functionalities. The warranty does not cover damaged parts o caused by the user or by third parts.
DEMI5® is it a sea water reverse osmosis plant?
No it is a portable water softener.
What is the water hardness?
Hard water is water that has high mineral content (in contrast with soft water). Hard water minerals primarily consist of calcium, and magnesium metal cations, and sometimes other dissolved compounds such as bicarbonates and sulfates.
Calcium usually enters the water as either calcium carbonate, in the form of limestone and chalk, or calcium sulfate, in the form of other mineral deposits. The predominant source of magnesium is dolomite. Hard water is generally not harmful to one’s health.
What a water softener does?
Water softening is the act of reducing the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in hard water. Conventional water-softening appliances depend on an ion-exchange resin in which “hardness” ions trade places with sodium ions that are electrostatically bound to the anionic functional groups of the polymeric resin. A class of minerals called zeolites also exhibits ion-exchange properties; these minerals were widely used in earlier water softeners. Water softeners may be desirable when the source of water is a well, or municipal or private. The water to be treated passes through a bed of the resin. Negatively-charged resins absorb and bind metal ions, which are positively charged.

The resins initially contain univalent hydrogen, sodium or potassium ions, which exchange with divalent calcium and magnesium ions in the water. As the water passes through the resin column, the hardness ions replace the hydrogen, sodium or potassium ions which are released into the water. The “harder” the water, the more hydrogen, sodium or potassium ions are released from the resin and into the water. Resins are also available to remove carbonate, bi-carbonate and sulphate ions which are absorbed and hydroxyl ions released from the resin. Both types of resin may be provided in a single water softener. As these resins become loaded with undesirable cations and anions they gradually lose their effectiveness and must be regenerated. If a cationic resin is used (to remove calcium and magnesium ions) then regeneration is usually effected by passing a concentrated brine, usually of sodium chloride or potassium chloride, or hydrochloric acid solution through them.
What is the ion Exchange resin?
An ion-exchange resin or ion-exchange polymer is an insoluble matrix (or support structure) normally in the form of small (1/2 mm diameter) beads, usually white or yellowish, fabricated from an organic polymer substrate.
The material has highly developed structure of pores on the surface of which are sites with easily trapped and released ions. The trapping of ions takes place only with simultaneous releasing of other ions; thus the process is called ion-exchange. There are multiple different types of ion-exchange resin which are fabricated to selectively prefer one or several different types of ions.
What is the RINSE (regeneration phase) needed for?
As these resins become loaded with undesirable cations and anions they gradually lose their effectiveness and must be regenerated. If a cationic resin is used (to remove calcium and magnesium ions) then regeneration is usually effected by passing a concentrated brine, usually of sodium chloride or potassium chloride, or hydrochloric acid solution through them.
How long is the RINSE time of DEMI5®?
15/20 minutes
Where can I find the DEMI5®’s user instructions?
On the front face of DEMI5® all the user’s instructions of the product are explained and English and Italian.

Phase1 PRODUCTION. This is the softening phase.
Phase2 Back Wash (10 min), to move the beads and prepare the regenerations of resins.
Phase 3 RINSE (15/20 min), re-generation phase to re-activate the exchanging capacity of resin.
When should I change the charcoal pre-filter of DEMI5®?
Using water coming from the municipalities mains from 3 to 4 months.
How much salt does DEMI5® consumes during the re-generation phase?
850 gr
How can I know when I have to re-generate my DEMI5®?
1) When limescale is noticed on the surfaces while using DEMI5® a rinse phase will be needed.
2) The hardness of the water can be checked by the test strips (HP HARDNESS TEST), when at least one of the red point on the strips is detected, a regeneration will be needed.
3) Furthermore DEMI5® is equipped by a liter counter that allows to understand the re generation frequency (in terms of produced liters each production cycle), depending on the hardness level to be softened.

1 violet square on the strip correspond to 3000 lt before the re-generation
2 violet square on the strip correspond to 2000 lt before the re-generation
3 violet square on the strip correspond to 1500 lt before the re-generation
4 violet square on the strip correspond to 1000 lt before the re-generation
How do I read the hardness strips?
First violet square: 7°F Soft water
Second violet square: 12,5°F Medium hard water
Third violet square: 25°F Hard Water
Fourth violet square: 36°F Very hard water
How many litres can I produce with DEMI5® before rinsing the resins?
1 violet square on the strip correspond to 3000 lt before the re-generation
2 violet square on the strip correspond to 2000 lt before the re-generation
3 violet square on the strip correspond to 1500 lt before the re-generation
4 violet square on the strip correspond to 1000 lt before the re-generation
Does DEMI5® decrease the mains circuit pressure?
No. The loss of pressure is minimal.
Which is the conductivity of the water produced by DEMI5®?
A little bit higher (120 µS more) compared to the water feeding the system.
