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.

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
4
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.

• If the daily pressure is over 5.5 bars, nighttime pressure
may exceed the maximum. Please install a reducing valve if
needed. (A pressure reducing valve may reduce the flow). If
your home is equipped with a back flow preventer, you should
install an expansion tank in accordance with local legislation.
• It is also recommended to install a silicophosphate filter at
the outside of the system, this way you will protect the insta-
llation from the corrosive tendence of the softened water.
5.3 Setting up and maintenance
• The system must be periodically sanitized. For more infor-
mation see section 8.
• The system maintenance has to be carried out by qualified
technical people and following the suitable hygienic condi-
tions. (For more information please contact the technical ser-
vice of your distributor).
6. INSTALLING PROCESS
Denver installation process must be carried out by qualified
technical people. Please follow the advises of section 5 and
warnings of this manual.
Taking into account that the system that you are going to
install will improve the quality of the water that it is going to
be consumed and that this is considered a food, all tools
used for the assembling and installation should be clean
and in no case can be contaminated nor impregnated of
grease,oils or oxides. The job should be carried out with
the proper attitude and hygienic conditions considering
all necessary precautions with everything related to the
materials that are going to be in contact with the treated/
to be consumed water (Please contact your distributor for
more information).

light coating of silicone grease on the bypass valve o-rings.
7. You will be supplied with a in and out noryl set of connec-
tions male 1”.Be sure that the clips snap firmly into place so
the bypass will not pull out.
8. You should measure,cut, and loosely assemble pipe and
fittings from the main water pipe to the inlet and outlet ports of
the water softener valve. Be sure to keep fittings fully together,
and pipes squared and straight. Check that hard water supply
goes to the water softener valve inlet side.

If using other
Other pipes and fittings suitable for potable water supply as
required by manufacturer or local legislation.
6.2 Installation step by step
1. The system should be always installed with the by-pass
valve supplied. If desired it can be installed a by-pass with 3
valves. The bypass of Denver systems has several positions.
RECOMMENDED INSTALLATION
2. Close the main water supply valve, near the well pump or
water meter.
3. Open all faucets to drain all water from the house pipes.
NOTE: Be sure not to drain water from the water heater
because it can be damaged
“DANGER” Excesive weight hazard. At least two people are
required to move and lift salt bags. Faillure to do so can result in
back or other body parts injury.
4. Move the water softener into installation position. Set it on a
level surface. If needed, place the water softener on a section
of plywood, a minimum of 2 cm thick. Then, shim under the
plywood to level the water softener. Please see picture below:

NOTA: Inlet and outlet are marked on the valve.Trace the
water flow direction to be sure.
IMPORTANTE: Be sure to fit, align and support all plum-
bing to prevent putting stress on the softener valve inlet
and outlet.Undue stress from misaligned or unsupported
plumbing may cause damage to the valve.
SOLDERED COPPER
1. Thoroughly clean and apply solder flux to all joints.
2. Make all solder connections.
NOTE: Do not solder with installation tubes attached to sin-
gle valve bypass. Soldering heat will damage the valve.
IMPORTANT: When installing the copper tubes and ground
clamp assembly to the single valve bypass, the ground
clamp must be secured in place. If necessary tighten the
screw.

6.4 Start-up programming
Denver softeners are configured to work with delayed regene-
rations (02.00 am).
ROGRAMMING:
1. Connect the provided transformer to the electrical con-
nector at the back of the system. The timer will show service
position.
IMPORTANT: After connecting the system can show fo-
llowing message:
12
This message indicates that the system is placing itself in
service position.If after two minutes this message is still in
the display please contact your distributor.
2. Press “MENU” key for three seconds to enter into the inter-
nal programming. By pressing “UP” y “DOWN” keys the di-
fferent parameters can be selected,and pressing REGEN key
we can access to modify it (selected parameter flashes). With
“UP” y “DOWN” keys we can modify the selected parameter
and pressing REGEN key one final time the parameter will be
confirmed. Parameters that you can modify are as follows:
HOUR OF DAY: Format 0:00-24:00.
LANGUAGE: Spanish or English
UNITS : Metric system or US units
TYPE OF REGENERATION: There are several as follows:
Time initiated (--) Delayed regenerations according to selected
frequence (Ex: Regenerates every 3 days at 02:00 am ).
Meter immediate: (MI) Regenerations are stated as per treated
volume of treated water. When remaining volume is 0 starts a
regeneration.
Delayed regenerations: (MD) Regenerations are delayed accor-
ding to volume. When the remaining volume is finished the
system starts the regeneration the same day at the program-
med hour.
Mixed regeneration (MR) Similar to delayed regeneration but it
allows to program a máximum period of time between rege-
nerations.
NOTE: Mixed regenerations are recommended. If you want
to select another type of regeneration, please contact
your distributor.
SYSTEM CAPACITY: It is necessary to program the volume of
the water that can be treated by the system. To calculate it
please follow the indications as stated below:
Volume(m3) = Exchange capacity (º HFxm3)
Hardness (º HF)
Where:
EXCHANGE CAPACITY:
It is the amount of hardness that can be retained by the sys-
tem. See the table below.
HARDNESS:
Hardness of inlet water in French degrees ºHF.

VOLUME:
Amount of water that can be treated by the system.
THIS IS THE PARAMETER THAT SHOULD BE PROGRAM-
MED INTO THE SYSTEM.
Example: A softener of 30 liters of resin with a hardness of
40ºHF.
4,9 m3 must be programmed inside capacity parameter.
In case of adjusting the residual hardness of treated water with
a mixing screw the initial hardness should be compensated
with the residual value.
Example:
Initial hardness:
40ºHF
Residual hardness:
5ºHF
Volume:
(m3) = 195 / (40-5) = 5,5m3
Capacity to be compensated/programmed: 5,5m3

CHECKING MENU:
By pressing “UP” y “DOWN” keys simultaneously when the
system is working the display shows additional information of
the softener.
REGENERATIONS:
To start an immediate regeneration you only need to press
REGEN key for three seconds.
REGENERATION STAGE:
Once the regeneration is started, it can be cancelled by pres-
sing any key. However the stage can only be cancelled when
the motor of the valve stops (the display will be flashing).

7. START UP
7.1 Hydraulic start-up
Prior to initiate the start-up of the system make sure that all
previous steps regarding installation. Ensambling and pro-
gramming have been correctly effected and according to the
instructions of this manual and according to local regulations.
To start up follow the following steps:
Do not put salt inside the system till the end of the start-up pro-
cess. In order to avoid air pressure upon the softener and the
plumbing system, follow the instructions in order.
1. Put the bypass valve in “bypass” position.
2. Open two or more faucets (total aperture) of cold treated
water besides the softener, to get water from it.
3. Open completely the inlet valve. Leave the water flow till
you get a continuos flow from the faucets, without air bubbles.
4. Connect the timer to the power supply with the supplied
transfomer for this purpose.
5. The timer will be placed in service position, if it is not like
this, revise the section 6.3 of Denver timer.
6. Press “REGEN” key during three seconds to start a regene-
ration. After some seconds the system will be placed in Bac-
kwash position.
7. Open inlet valve very slowly allowing the water to enter into
the softener. Water flow at this moment should be little becau-
se this way the water will come through the inferior part of the
vessel circulating till it will get to the drain.
8. When waters comes through the drain with a continuos
flow open please open inlet valve completely. In this moment
the water will be totally inside the vessel and a higher flow will
not damage it. Some coloration (yellow or brown) could be
observed in drainage flow. That coloration is originated by resin
preservatives and it is normal.
9. Please maintain this position (water flowing through the dra-
in) until coloration disappears.
10. Close inlet valve for five minutes and all the air trapped with
the resin will float to the upper part of the vessel.
11. Open inlet valve one more time for some minutes to ensu-
re that all the air inside the vessel has been removed.
12. Cancel the current stage of the regeneration until refill sta-
ge. The brining tank will start refilling by itself. In this moment
the system will end the regeneration started in point 6.
13. Start another regeneration. Wait until the system is placed in
backwashing position nbr.6 and cancel this stage by pressing
any key.
14. The softener will start to suction water from the tank (bri-
ning position). Check that the softener suctions water from
the tank.
15. Cancel the remaining stages of the regeneration.
16. Put the by-pass in service position and check that the
treated water has been correctly softened (see Section 7.3).
17. Fill the tank with salt.
18. The system is ready to work. Start-up process is finished.
“WARNING” Excesive weight hazard at least two people are
required to move and lift salt bags. Faillure to do so can result in
back or other body parts injury.

3. Shake it.
4. If the water becomes blue it means that it is completely
softened, if it has a reddish means that presents some kind
of hardness.
5. Add some drops of B reactive till the water gets blue.The
quantity of drops used will be the quantity of hardness in ºHF
found in the tested water.
DROPSTO GET BLUE WATER
7.2 Regulation of residual hardness
As stated out in section 2.7. it is recommended not to supply
completely softened water to household installations.
Denver systems have a residual hardness regulator that allows
to adjust the hardness quantity in the treated water.
This works making a small test of non treated water with a
completely softened water.
In order to regulate the residual hardness you should carefully
open the regulator.
Now you can test the hardness of the outlet water and check
that it is according to the desired values. If it is not like this
adjust the regulator and check it again.
ATENTION: The hardness regulator is supplied comple-
tely closed, so if you do not regulate it the softener will
provide a totally softened water.
7.3 Hardness checking
In order to check the hardness of the water with the tester
(code 271800), you should follow following steps:
1. Prepare the water to be analyzed
2. Add two drops of indicator reactive A

8. MAINTENANCE/SANITIZING
The Denver softeners, being automatic, do not require a com-
plex maintenance.
In order to ensure a correct working of the system it is enough
to make the following checking from time to time as showed
in the table below:
It is important not to make the sanitizing and the descaling
treatment at the same time, because the chemical products can
react in a dangerous way. You should alternate both processes as per
indicated frequency.
SALT FILLING
Please revise the level of the salt inside the tank.. It should be
mínimum: 1/3 of the tank. If the system runs out of salt before
the refilling the softener will produce hard water. When finis-
hing the checking please make sure that the cover is correctly
closed.
NOTE: In humid areas it is best to keep the salt storage
level lower and refill the tank more often.
RECOMMENDED SALT: Coarse salt tablets or balls with less
than 1% of impurities.
NOT RECOMMENDED SALT: Rock salt, with impurities, block,
granulated, table, ice melting, or for kitchen use.
BREAKING A SALT BRIDGE
Sometimes, a hard crust or salt bridge is formed in the brine
tank. It is usually caused by high humidity or the wrong kind
of salt. When there is a salt bridge, and empty space forms
between the water and the salt. Then the salt will not be dis-
solved in the water to make brine and without brine the resin
bed does not regenerate and you will get hard water.
If the storage tank is full of salt, it is hard to tell if you have
a salt bridge because salt is loose on top but the bridge is
under it.
Take a tool or a broom handle, for instance, and hold it next
to the water softener, measure the distance from the floor to
the rim of the water softener. Then push the broom handle
straight down into the salt. If you find a hard object, it is most
likely a salt bridge. Carefully push into the bridge in several
places to break it.
“WARNING” Do not use any sharp or pointed objects as you
may puncture the brine tank
SANITIZING:
Every year it is recommended to make an sanitizing process
as follows:
1. Open the covers of the salt tanks and put inside about 20 a
30 ml (2 or 3 caps) of Bacwater (652100.) inside the funnel.
Close again.

2. Make sure that the bypass valves are working.
3. The disinfenction process will be done when the regenera-
tion finishes and the disinfection solution has been extruded
from the softener to the drain.
REMOVING INSCRUSTATION:
Once a year it is recommended to make a cleaning with
Clean Softener (611000), a product specially designed for
the cleaning of your softening system. This product, because
of its special formulation, will clean the resin eliminating all
kind of iron and other remaining metals that represent a con-
tamination and at at the same time it will remove all possible
incrustations in the inner passages of the valve.
NOTE: Follow carefully the instructions of the use of the
product stated out on the label of the same.
The maintenance and sanitizing of the system should be ca-
rried out by a specialized technician qualified in hygienic con-
ditions and following the specific indications of each product.
