1. PRESENTATION
The water treatment equipment that you have bought is a sof-
tener of last generation with one of the most advanced control
heads in the market.
The quality of the water in our environment is its getting wor-
se day by day and this is causing an increase of the water
hardness , this fact can cause incustration problems in the
connections and can affect the right performance of the equi-
pments . The use of this water increases the maintenance
cost and reduces their life time.
This reality has driven us to design this range of household
softeners specially thought to ensure the supply of a high sof-
tened water in your home.
Your softener DENVER range will provide you and your family
the following advantages.
BENEFITS AND ADVANTAGES:
Reduce the hardness present in the water, causing the
incrustations.
ENERGETIC SAVING: Avoid the future incrustations in
the pipes and connections.
Great wellness sensation in the shower.
Soft and smooth skin.
Increases the life time of the electronic devices and
heating systems.
ECONOMIC SAVING: Reduces the consumption of the
soaps, softeners and chemical products.

the tank storage from time to time.
It is important that you keep and read this manual carefully befo-
re the installation and starting up of this equipment. If you have
any doubt about the installation, use or maintenance of this equipment,
please contact with the technical assistance service (T.A.S.) of your dis-
tributor.

2. INTRODUCTION
The DENVER 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.
DENVER equipments will produce softened water of high qua-
lity and they also incorporate a system of residual hardness
that allows you to choose the ideal hardness for your home.
Its simple electronical timer can start-up the equipment
in an easy and quick way.
2.1 What is hardness?
By hardness we understand the quantity of the encrusted
salts present in the water, formed mainly by sales of low solu-
bility in calcium and magnesium. Salts causing the hardness
are mainly:
Calcium bicarbonate: Ca(CO3H)2
Calcium chloride: CaCl2
Calcium sulfate: CaSO4
Magnesium bicarbonate: Mg(CO3H)2
Magnesium chloride: MgCl2
Magnesium sulfate: MgSO4
These sales, because of their chemical features, tend to
precipitate getting hard in pipes and blocking them becau-
se of accumulation. At the same time the hardness has a
high tendence to be encrusted in the electrical resistance
of heaters and to precipitate inside the heaters because the
temperature rises. The combination of tough minerals and
soap produces a soap curd or cutted soap. This curd soap
reduces the cleaning action of the soap. The mineral preci-
pitation of tough minerals form a crust on cooking utensils,
connections and plumbing fixtures. They even affect the tas-
te of the food.
MAINLY PROBLEMS PROBLEMÁTICAS
Precipitation in pipes, accessories and equipments.
Precipitation in electrical resistances, increase of
energetic consumption because of isolation.
More use of soap and chemical products.
Reduction of life time of the electronical devices and
More need of maintenance.

All these problems are solved when using a softener DEN-
VER range, because the water obtained after being treated
with the system is absolutely free of encrusted salts.
In the most part of Europe the hardness is being expressed
in hydrometric French grades, but there are other measure-
ment units depending on the zone where we are located.
Please see above the equivalents more usual
2.2 How is your system working
The water softening in your system is being done with an
ionic exchange process. To do this we use ionic exchange
resins that have the chemical capacity to capture the Cal-
cium ions (Ca) and Magnesium (Mg), removing them from
the water.
At the same time that the ions of calcium and magnesium
are captured by the resin they liberate Sodium ions (Na), that
with their chemical features create sales with a much higher
solubility ,avoiding the problems related to hardness.
Moreover when we soften the water we increase the sodium
level of the same. You can find a wider explanation of this
aspect in point 2.8.
IONIC EXCHANGE RESINS:
They are synthetic components, normally spheric and
they have the capacity to capturate the chemical par-
ticles present in the water, exchanging them by others.
In the case of the softening we use hard cationic resins,
made of styrene copolymers and divinylbenzene in sul-
fonated basis.
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 remains free to
allow a correct regeneration of the resin bed.

2. Introduction

During the treatment process the water gets through the mul-
tiway valve by the entrance connection, flows to the upper part
of the softener through the distributor 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 val-
ve. It is sent with the out connection till the main water pipe for
consumption. In this point the system has a counter for treated
water to be contabilized.
2.3 Regeneration of the system
The quantity of the calciun and magnesium ions that the resin
can keep is limited so the volume of water that a softener can
treat is also limited. Because of this the system has to do from
time to time a process known by regeneration that allows the
resin to be charged again with sodium ions in order to be able
to make the softening process again.
In Denver systems the regeneration process starts automati-
cally when the systems detects that the exchange capacity is
going to finish, the timer incorporated in the system allows to
configurate in a different way the starting of the regeneration,
please see section 6.3 in order to get more information about
how the programme works.
The regeneration of a softener system is made of different
parts, each with a concrete finality
BACKWASHING:
The water gets into the vessel through an inferior collector,
making a washing and a floffing of the resin bed and
allowing, this way, the following regeneration process.
ASPIRATION OF BRINE:
Through an aspiration process for venturi effect the system
suctions the brine liquid solution previously prepared for the
regenerating tank. This salt solution is introduced into the sof-
tening vessel getting in contact with the ionic exchange resin
and starting the regeneration.
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.
LLENADO DEL DEPÓSITO:
The volume of water goes automatically to the brine tank in
order to prepare the necessary brine to be consumed in the
next regeneration.This process is automatic, so normally it is
not necessary to put more water in the brine tank (except du-
ring the starting up as shown in section 7.

NOTE: During the regeneration process the systems allows
the passage of the non treated water in order to ensure
the disponibilty of the water to be consumed.
2.4 Regeneration grade and capacity
The exchange capacity is the quantity of hardness that a parti-
cular resin volume can keep before getting useless. This value
can be expressed like ºHFxm3/liter of resin.
The higher the resin volume is the higher hardness can be
kept by this resin before getting useless. This way it will be
able to treat a higher quantity of water before starting regene-
ration. It is important to choose the system that better suits the
concrete needs of each installation.
Depending on the quantity of sodium chloride used to rege-
nerate each liter of resin the capacity of exchange can differ.
Normally the denver systems are provided with a program-
mation with a regenerating grade of , 250grNaCl/resin liter and
an exchange capacity of 6,5ºHFxm3/resin liter.
2.5 Work volume
The softeners with ionic exchange should respect the suitable
contact times between the water to be treated and the resin in
order to ensure that the softening process is correctly carried
out. For DENVER systems you should respect following work
process:
Minimum volume (liters/hour): Resin volume x 4
Maximum volume (liters/hour): Resin volume x 40
In case of work volumes are out of the recommended ranges
this can affect the correct work of the system (too high charge
loss, harness leak…)
You can find more information about the minimum and maxi-
mum volumes for each type in the general characteristic board
2.6 Hardness leak
The ionic exchange process in which the softening water is
based can be affected by different parameters that can redu-
ce its efficacity creating a kind of hardness leak.
HIGHER SODIUM CONCENTRATION IN THE TREATED
WATER The ionic exchange process in which the softening
water is based can be affected by different parameters that
can reduce its efficacity creating a kind of hardness leak.
EXCESSIVE VOLUME
It can affect the exchange process
REGENERATION GRADE
If there is no enough time, part of the hardness cannot be kept
by the resin
2.7 Residual hardness
Depending on the application of the treated water it is ne-
cessary to have it completely softened or on the contrary it
is better to have a certain amount of residual hardness. The
DENVER systems are designed to provide softened water and
even in this case the control valve has a residual mixing hard-
ness that allows to regulate the desired grade of hardness in
the treated water. (see Section 7)
NOTE: For drinking water it is recommended a residual
hardness between 5 and 10ºHF when the tubes are of
copper and between 8 and 10ºHF when the tubes are
of iron (in this last case it is recommended to install af-
terwards a polyphosphat filter).
2.8 Sodium increase
The majority of the sodium that we are daily consuming co-
mes with the food and also with the preserved/canned food
because the salt is an excellent preservative and it is used like
and additive for the prepared products.
The ingestion of sodium with the drinking water is low compa-
red with the quantity that we are getting with the food.
However, it is important to bear in mind, as we have
said before, that the softeners equipments increase the so-
dium cocentration existing in the treated water (compared to
the concentration of the same at the initial moment of water
treatment).

The following board gives you an orientation about the increa-
se of the sodium concentration in the treated water as per

ATENTION: The recommended limit of sodium for the
water for human consumption is of 200 ppm. Depen-
ding on the sodium concentration and the hardness of
the water to be treated the softened water can present
sodium concentrations higher than recommended. If this
happens or in case of people on low sodium diets we re-
commend the installation of a reverse osmosis equipment
for the drinking water.

5. WARNINGS
The water treatment equipments serie Denver are not intended
to be used to produce POTABLE WATER. Their function is to eli-
minate the hardness of the water obtaining a treated softened water that
will avoid all problems related to hard water.
If the treated water does not come from a public net or it is
from an unknown source it will be necessary to carry out a phy-
sical- chemical and bacteriological test in order to ensure the correct
potabilization as per tecniches and systems needed (BEFORE the system
is INSTALLED). Please contact you distributor and he will recommend you
the most suitable treatment according to your needs.
5.1 Requirements for the proper working of
the system
• Do not supply hot water (T>36ºC) to the system.
• The temperature must be between 4ºC and 45ºC.
• If posible the system must be installed in a dry
environment,free of acid vapors. At the same time a proper
ventilation must be insured.
• The minimum pressure should be of 2,5 bars, and if this
is not possible you should install a pressurization system that
allows to get a proper pressure.
• If the inlet pressure is higher than 5,5 bars you should install
a pressure regulator
• The water treated should be filtered so it is recommended
the installation of a previous filter in order to remove the sus-
pended particles that can be found in the inlet water. It is
recommended the use of a filtration kit code 795600, that
includes all necessary components
If a suitable filtered is not installed these suspended particles
could block the holes and the inner injectors of the system and
could affect the proper working of the same.
5.2 Installation
•To condition all water at home, install the water softener
close to the water supply inlet, and before all other plumbing
connections. Outside faucets should remain on hard water
to avoid wasting conditioned water and salt. In any case and
considering the sodium increase in softened water, it is not
recommended its use for watering because it can damage
the growing of plants and vegetables.
• In case of having to prepare the place for the installation of
the system you should follow the national laws in force regar-
ding electric and hydraulic installations.
• A drain is needed for regeneration discharge water. The
drain connection should be of free exit. The diameter of this
connection should be of minimum 1”. The máximum distance
between the softener and the floor drain should be no more
than 6 meters. A nearby drain is needed to carry away the
regeneration discharge water. A floor drain, close to the water
softener, is preferred . A laundry tub or a standpipe are other
drain options.
• The installation place should have enough room for the sys-
tem, the accessories and the connections required in order to
carry out a safe maintenance.
• In no case you will install the systems in the open air.
• Do not locate the water softener where hot temperatures
occur or near to a warm supply.
• environment where the system is installed should have all
the proper hygienic and sanitary conditions.
• All outside leakings over the system should be avoided:
plumbings, drain…
• In case of softened water supplying a hot water or steam
device, it will be necessary to install a checking valve between
the softener and the water heater in order to avoid hot water
returns that could damage the system.
• It is recommended to foresee the installation of the simple
valves for the water to be treated and for the softened water
near the softener.
• If there are quick closing valves in your installation it is re-
commended to use a non ram device.
• The softener works only on 12 volt- 50 hz electrical power
supplied by a direct plug-in transformer included. Please use
the transformer and connect it to a floor of 220 – 240 V, 50Hz.
At the same time you should be sure that the home installation
is properly protected with a device like a switch or or a fuse.
