1.2. BEFORE STARTING
See ‘Section 5’ before installing the water softener.
Carefully follow the instructions for the installation
(Warranty may be considered void, if the installation is
faulty).
Please read the entire manual before undertaking ins-
tallation. Then, collect all necessary materials and tools
for the installation.
Check the plumbing installation.
All installations must be done according to the law in
force in each region or country.
Please be careful when handling the water softener.
Do not knock it over, let go of it or place it onto sharp
objects.
Under no circumstances should the softener be insta-
lled outdoors, since it must be protected against sunli-
ght and rough environmental conditions.
2. INTRODUCTION
The DENVER PLUS PLUS softeners equipments will avoid
you all kind of problems caused by the hardness of the
water and will reduce a lot the maintance requested by
your electronical devices. They will have a longer life.
These systems come with a residual hardness regula-
tor as standard, which allows selecting the appropriate
hardness for your home.
Its user-friendly electronic programmer will allow you
to put the system into operation in an easy and fast
manner.
2.1. WHAT IS HARDNESS?
Hardness is the quantity of scaling salts present in wa-
ter, which are mainly composed of low solubility salts of
calcium and magnesium. The main salts causing hard-
ness are listed below:
These salts, due to their chemical properties, have a
tendency to precipitate, producing scale on pipes and
obstructing them as they accumulate.
In the same way, hardness has a high tendency to scale
on the electrical resistors from heaters and to precipi-
tate in heaters when temperature increases.
The combination of hard minerals and soap produces
a soap curdling, wich reducest he cleansing properties
of soap.
The precipitation of hard minerals build a layer on coo-

have included safety messages in this manual and on
your appliance.
This is the safety alert symbol.
This symbol alerts you to the potential hazards
that can be risky for you and for others.
All safety messages will follow the safety alert
symbol or either the word “DANGER” or “WARNING”.
• DANGER: Severe or fatal risk if the following instruc-
tions are not immediately followed.
• WARNING: All safety messages provide information
about the possible danger, how to reduce the risk of
injury and what might happen if the instructions are not
followed.

User manual
During the treatment process the water gets through
the multiway valve by the entrance connection, flows
to the upper part of the softener through the distri-
butor producing this way an ionic exchange inside the
resin bed.
The treated water is collected by the distributor and
driven through the inner tube through the vessel till the
multiway valve. It is sent with the out connection till the
main water pipe for consumption. In this point the sys-
tem has a counter for treated water to be contabilized.
2.3 REGENERATION OF THE SYSTEM
The quantity of calcium and magnesium ions that the
resin may retain is limited; therefore, the water volume
a water softener can treat is limited as well. The system
must periodically carry out a process known as regene-
ration, which allows the resin to recharge with sodium
ions, so it can continue softening water.
In DENVER PLUS PLUS systems the regeneration process
starts automatically when the systems detects that the
exchange capacity is going to finish, the timer incorpo-
rated in the system allows to configurate in a different
way the starting of the regeneration, please see sec-
tion 6.3 in order to get more information about how the
programme works.
The regeneration of a softener system is made of diffe-
rent parts, each with a concrete finality
Backwashing:
The water gets into the vessel through an inferior co-
llector, making a washing and a floffing of the resin bed
and
allowing, this way, the following regeneration process.
Brine aspiration:
Through an aspiration process for venturi effect the sys-
tem suctions the brine liquid solution previously prepa-
red for the regenerating tank. This salt solution is intro-
duced into the softening vessel getting in contact with
the ionic exchange resin and starting the regeneration.
king utensils, connections and plumbing fixtures. It may
even alter the taste of food.
Main problems:
· Precipitation on pipes, fixtures and appliances.
· Incrase of the energy consumption due to the gene-
rated isolation.
· Higher soap consumption
· Reduction of the electical appliances’ service life and
increase of the maintenance needed.
All these problems are greatly reduced when using a
water softening system.
For the most part of Europe, hardness is indicater in
French hydrometic degrees, but there are also other
measuring units, according to each region.
Below are the most usual equivalences.
2.2. HOW DOES YOUR SYSTEM WORK?
Water softening is carried out by means of an ion ex-
change process. On this purpose, the system uses re-
sins with the chemical capacity of capturing Calcium
(Ca) and Magnesium (Mg) ions and removing them from
water.
When Calcium and Magnesium ions are captured by the
resin, two Sodium (Na) ions are released which, due to
its chemical properties, produce salts with a higher so-
lubility , thus avoiding all hardness-related problems.
Therefore, when water gets softened, its sodium level
increases.
Further information on this procedure can be found in
‘Section 2.8’.
Ion exchange resins:
They are synthetic compounds, usually with a spheri-
cal shape, able to capture certain chemical substan-
ces present in water, which then exchange for other
substances. Water softening uses strong cation resins,
which are composed of styrene copolymers and divinyl-
benzene with a sulphur base.
The exchange resin charge is located inside the vessel
of the softener, attending an important part of volume
of the same (between 60 and 75% depending on the
model). It is compulsory that one part of the vessel re-
mains free to allow a correct regeneration of the resin
bed.

resin, in order to ensure that the softening process is
carried out properly.
For the DENVER+ equipment, please respect the mini-
mum and maximum flow rates indicated in the Techni-
cal Characteristics section.
If the working ranges are outside the recommended
ranges, the proper operation of the system will be
affected (excessive loss of charge, hardness leakage,
etc.)
2.6 HARDNESS LEAK
The ion exchange process on which water softening is
based may be affected by different factors, which can
reduce its efficiency and cause a certain level of hard-
ness leakage.
High sodium concentration on water to be treated.
It may interfere in the exchange process.
Excessive flow rates
Since there is not enough contact time, some of the
hardness may not be retained by the resin.
2.7 RESIDUAL HARDNESS
Depending on the final use of treated water, it may be
necessary to obtain fully softened water or, on the con-
trary, it may be desirable to leave some residual hard-
ness.
These systems have been designed to supply fully sof-
tened water, but the by-pass integrates a residual hard-
ness mixer, which allows the regulation of the desired
hardness degree in treated water (see ‘Section 7’).
NOTE: For human consumption water, it is recom-
mended to have a residual hardness between 5
and 8 ºHF if pipes are made of copper, and be-
tween 8 and 10 ºHF if they are made of iron (for the la-
tter, it is also recommended to install a silicopolyphos-
phates filter afterwards).
2.8 SODIUM INCREASE
Most of the sodium we consume on a daily basis co-
mes from food, specially processed food, since salt is
an excellent preservative and is used as an additive in
prepared products.
Sodium consumption through the water we drink is ra-
ther low when compared with that obtained from food.
WARNING: As mentioned above, water softeners
reduce the Calcium and Magnesium concentra-
tion in water by replacing it for Sodium. Thus, they in-
crease the sodium level in water.
The maximum recommended sodium level in water for
human consumption is of 200 ppm. Depending on the
sodium concentration and the hardness of water to be
treated, it is possible that softened water contains a hi-
gher concentration of sodium than that recommended.
Slow rinse:
It refers to the movement in the resin bed of the salt
solution previosly aspirated, this way the contact of the
salt with the resin is higher and the regeneration of the
same is optimized.
Fast rinse:
The water flows through the resin bed making a final
wash of the same and ensuring the total removing of the
salt that can be inside the vessel.
Refilling the brine tank:
The volume of water goes automatically to the brine
tank in order to prepare the necessary brine to be con-
sumed in the next regeneration.This process is automa-
tic, so normally it is not necessary to put more water in
the brine tank (except during the starting up as shown
in section 7.
NOTE: During the regeneration process the sys-
tems allows the passage of the non treated water
in order to ensure the disponibilty of the water to
be consumed.
2.4 REGENERATION RATE AND CAPACITY.
The exchange capacity is the quantity of hardness that
a certain resin volume can retain before getting exhaus-
ted. This value is usually expressed as ºHFxm3.
The higher the resin volume of the system is, the higher
will be the quantity of hardness that can be retained
before the resin gets exhausted.
Depending on the quantity of sodium chloride used to
regenerate each liter of resin the capacity of exchange
can differ.
2.5 WORK VOLUME
Water softeners using ion exchange must respect cer-
tain contact periods between water to be treated and

User manual
Should this be the case, or if water is to be consumed
by persons who must follow a low-sodium diet, it is
recommended to install a household reverse osmosis
system to drink the water.
