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-

It is important that you keep and read this ma-
nual carefully before 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 distributor.
1.1. SOFTENER SAFETY
Your safety and other’s safety are very important. We
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

tain contact periods between water to be treated and

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

4. UNPACKAGING AND CONTENTS VERIFICATION
It is important that before installing and starting the
system you check the box and conditions of the mate-
rial received in order to ensure that the system has not
been damaged during the transport
Any claim for damages during the transport must be de-
tailed together with the delivery note or invoice to the
distributor, mentioning the name of the carrier within a
maximum period of 24 hours after the goods reception.
The DENVER PLUS softeners are provided completely
ensambled and have the following parts:
• Volumetric DENVER PLUS valve 850 : Automatic and
made of Noryl. With isolating by-pass and mixing screw
of residual hardness.
• Vessel containing the resins, made in PRFV.
• Resin for the ionic exchange, cationic type, special for
softening, provided inside the vessel.
• DENVER PLUS cabinet, made of plastic, with salt capa-
city for multiple regenerations.
• Brine system aspiration protected with plastic funnel.
• Packaging and protection, including a presurized air
balloon to avoid the vessel movements.
• Please read carefully this manual before starting ins-
talation.
The air balloon has to me removed before procee-
ding the system installation.
The packaging material can be recycled and must be
thrown away in the suitable recycling bins or to be deli-
vered to the specific centre for the collection of waste
material.
The machine that you have acquired has been designed
and manufactured with high quality materials and com-
ponents that can be recycled and reused. This product
must not be thrown away into the usual urban rubbish
bins. When you want to throw the machine away, it must
be taken to a specific local centre for the collection of
materials, stating that it contains ion exchange resin.
In order to obtain more information about how to dis-
pose of your equipment, contact the management of
urban waste service or the establishment where you
acquired the system.
The proper collection and treatment of the machines
that can no longer be used contributes to the preserva-
tion of natural resources and also to avoiding potential
public health risks.
5. WARNINGS
The DENVER+ series water treatment systems ARE
NOT WATER PURIFIERS. Its aim is to remove the
hardness from water, leaving a softened and trea-
ted water which will prevent all problems associated
with hard water.
Should the water to be treated not come from
a public water supply, that is, from an unknown
source, a physical-chemical and bacterial analysis
of the water shall be necessary, with the aim of ensu-
ring its proper purification by applying the techniques
and systems appropriate to each case, PRIOR TO THE
INSTALLATION of the system.
5.1 REQUIREMENTS FOR THE PROPER WORKING OF
THE SYSTEM
• Do not use hot water in the system (T>35ºC).
• The ambient temperature must be between 4 ºC and
45 ºC.
• The system should be installed in a dry environment,
free of acid vapours. Otherwise, please ensure a proper
ventilation.
• Water to be treated must be properly filtered, there-
fore, it is recommended to install a pre-filter to guaran-
tee the removal of suspended particles, which may be
swept along by inlet water.
Failure to install an appropriate filter would result
in particles obstructing the inner holes or injec-
tors of the system, thus affecting its proper operation.
• A minimum pressure of 2.5 bars must be ensured.
Should this minimum pressure not be available, a pres-
sure system shall be installed.
• If inlet pressure is higher than 5.5 bars, a pressure re-
gulator must be installed.
5.2 INSTALL ATION
• If the water softener must treat all the water supply
of your home, connect it to the general supply pipe be-
fore connecting the rest of the pipes, except for pipes
supplying the outside. Taps located outside the house
must supply hard water. Due to the sodium increase
in softened water, it is not recommended to use it for
watering, since it can negatively affect the growth of
plants and vegetables.
• In the event of modifying the home/workplace in or-
der to install the equipment in the planned location, it
should be done following national guidelines for interior
installations of water and electric supply.
• The installation location should have sufficient space
for the machine itself, its accessories, connections and
room for servicing and repair.
• The system should not be installed next to a heat sour-
ce or where it receives a direct flow of hot air.

User manual
• The drain connection, where water from regenera-
tion will be driven, must be underneath the installation
if possible. Drain connection must always have a free
outlet. The diameter of this connection must have a mi-
nimum size of 1”. The maximum distance between the
water softener and the drain intake cannot be higher
than 6 m.
• Raising the drain intake above the water softener level
is not recommended, since it can affect the brine suc-
tion and, thus, impair the regeneration process.
• In the event that this is deemed DENVER PLUS, it can
be raised a maximum of 1.5 m, provided that the inlet
pressure is higher than 4 bar.
• If the height is greater or there is not enough pressure,
contact your distributor.
• Under no circumstances should the equipment be
ins-talled outdoors.
• The environment where the equipment is to be ins-
talled should adhere to any appropriate hygiene and
sanitation conditions.
• Avoid any external dripping liquids from pipes, was-
tewater, etc. onto the equipment.
• Should softened water be supplied to a hot water or
vapour generator, it will be necessary to install a depen-
dable check valve between the water softener and the
generator, in order to prevent hot water from returning
to the system and damaging it.
• The existing pipelines must not have deposits of ei-
ther iron or lime. Replace all pipelines containing a great
amount of iron or lime deposits. In the event that pipe-
lines are blocked with iron, install a separate iron filter
unit before the water softener.
• It is recommended to install some valves for sample
taking both for treated and untreated water, as close as
possible to the water softener.
• If there are quick-closing valves, it is recommended to
install a device to prevent water hammers.
• The softener works only on 12 volt- 50hz electrical
power supplied by a direct plug-in transformer inclu-
ded.
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 a fuse.

PRECAUTIONS:
1. Reading and review: Carefully read all procedures,
guides and regulations before installing and using the
DENVER PLUS water softening equipment.
2. Treatment of chemicals: Avoid the presence of flam-
mable products or materials as a safety measure for
preventing the risks of explosion and fire. Make sure to
use the glue and the cleaning product for PVC in a we-
ll-ventilated area.
3. Eye protection: Wear safety goggles during the insta-
llation process to prevent any injury in your eyes, cau-
sed by the ejection of welding materials or metal and
plastic chips.
4. Welding: Use adequate protective equipment to pro-
tect the exposed surfaces against the flame of the gun
or an excessive temperature increase. Only use welding
guns WITHOUT LEAD.
5. Grounding: When installing a plastic pipe between
two metallic pipes, a grounding cable must be installed
to prevent the interruption of grounding continuity.
6. Easy reach: Use a ladder for working at heights which
are out of reach. If you must work at heights for a pro-
longed period of time, use adequate safety devices.
Note: We recommend that the installation is carried out
by a qualified installer. Failure to install the equipment
in accordance with this manual will render the warranty
void.
• If daytime pressure is higher than 5.5 bars, night-time
pressure may exceed the maximum. Please use a pres-
sure-reducing valve if necessary (a pressure-reducing
valve may reduce the flow).
• It is recommended to install a silicopolyphosphates fil-
ter in the system’s outlet to protect the pipes from the
corrosion of softened water.
Note: The warranty of the equipment does not cover
any damages due to the freezing of the equipment. If
you have questions about the DENVER PLUS water equi-
pment or if you think that it is not working properly,
contact your distributor.
5.3 SETTING UP AND MAINTENANCE
• The system must be periodically sanitised. See ‘Sec-
tion 8’ for further information.
• Maintenance should be carried out by qualified tech-
nicians who work under the appropriate hygienic con-
ditions. (For further information contact the technical
service of your distributor.)

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 PLUS systems
has two 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:
IMPORTANT: Do not place shims directly under the
salt storage tank.The weight of the tank, when full
of water and salt, may cause the tank to fracture at
the shim.

5. You will be supplied with a in and out noryl set of
connections male 1”.Be sure that the clips snap firmly
into place so the bypass will not pull out.
6. 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 softe-
ner valve inlet side.
Display LCD
NOTE: Inlet and outlet are marked on the valve.Trace
the water flow direction to be sure.
IMPORTANT: 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 unsu-
pported 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 single 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.
THREADED PIPE
1. Apply pipe joint compound or Teflon taple to all male
pipe threads.
2. Tighten all threaded joints and make all solder con-
nections.
CPVC PLASTIC PIPE
1. Clean, prime and cement all joints, following the ma-
nufacturer’s instructions.
NOTE: Do not solder with installation tubes attached
to single valve bypass.Soldering heat will damage the
valve.
OTHER
Follow the piping system manufacturer’s instructions
when using other pipe approved for potable water.
INSTALLING DRAIN HOSE
Measure, cut to needed length and connect the ½”
drain line to the water softener valve drain fitting. Use a
hose clamp to hold the hose in place.
NOTA: Run the green drain hose or copper tubing to
the floor drain. Secure drain hose. This will prevent
“whipping” during regenerations.
OVERFLOW INSTALLATION
Connect the storage tank overflow elbow installed in
the system to a near floor drain point. This point should
be no higher than the drain fitting on the salt storage
tank.
NOTE: Drain hose should be installed in a proper way
just to avoid that the water overflows and returns from
the drain hose.

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 programming have been correctly effected and ac-
cording to the instructions of this manual and accor-
ding to local regulations. To start up follow the following
steps:
Do not put salt inside the system till the end of the
start-up process. In order to avoid air pressure upon
the softener and the plumbing system, follow the ins-
tructions in order.
1. Put the bypass valve in “bypass” position.
2. Open completely two cold and treated water faucets
located after the water softener. Have it opened for
some minutes in order to ensure that all the trapped air
is removed from the system. Check also that there
are no leaks in the installation.
3. Plug the programmer to the power supply using the
transformer included in the system.
4. The program must be in service, otherwise please
check ‘Section 6.3’.
5. Press the “REGEN” button to access regeneration
menu. An immediate regeneration must be chosen. Af-
ter some seconds the unit will move to the Backwash
position.
6. Slowly open the water inlet valve to allow the entran-
ce of water inside the system. At this point, the inlet
flow must be rather low, since in this position water
will come in from the bottom of the bottle and flow
upwards to the drain.
7. When water starts flowing continuously through the
drain, fully open the water inlet of the system. At this
point, the bottle will be full of water and so a higher
flow will not produce any damage. Water going out to
the drain may be a bit yellowish or brown. This is com-
pletely normal, since it is due to the preservatives of
the resin.
8. Please maintain this position (water flowing through
the drain) until coloration disappears.

9. Close inlet valve for five minutes and all the air tra-
pped with the resin will float to the upper part of the
vessel.
10. Open inlet valve one more time for some minutes
to ensure that all the air inside the vessel has been re-
moved.
11. Cancel the current stage of the regeneration until
refill stage. The brining tank will start refilling by itself.
In this moment the system will end the regeneration
started in point 6.
12. Start another regeneration. Wait until the system is
placed in backwashing position nbr.6 and cancel this
stage by pressing any key.
13. The softener will start to suction water from the
tank (brining position). Check that the softener suctions
water from the tank.
14. Cancel the remaining stages of the regeneration.
15. Put the by-pass in service position and check that
the treated water has been correctly softened.
16. Fill the tank with salt.
17. The system is ready to work. Start-up process is fi-
nished.
“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.
7.2 REGULATION OF RESIDUAL HARDNESS
As stated out in section 2.7. it is recommended not to
supply completely softened water to household insta-
llations.
DENVER PLUS systems have a residual hardness regu-
lator 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 modify the residual hardness, lightly open
the regulating valve, as indicated in the images below.
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.

19
“WARNING” Do not use any sharp or pointed ob-
jects as you may puncture the brine tank
SANITIZING:
Every year it is recommended to make an sanitizing pro-
cess 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 re-
generation finishes and the disinfection solution has
been extruded from the softener to the drain.
8. MAINTENANCE/SANITIZING
The DENVER PLUS softeners, being automatic, do not
require a complex 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 indi-
cated 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 finishing 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 dissolved in the water to make
brine and without brine the resin bed does not regene-
rate 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.

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 contamination and at at the same time
it will remove all possible incrustations in the inner pas-
sages of the valve.
