INTRODUCTION
Thank you for choosing a BWT WS Range Water Softener.
On the following pages we provide full installation and operating instructions.
You may find this booklet easier to follow if you first take a few minutes to familiarise
yourself with the basic principles of the water softening process and benefits of the
"Millennium" valve.
FEATURES AND BENEFITS
At the heart of your BWT WS Range Water Softener is the Millennium valve controlled
by the BWT “Advanced Memory Electronic Control System” (AMECS). AMECS is
manufactured and tested to meet the latest EU standard for performance, safety and
testing of water softeners. The protocol used in the system design is based on the
extensive experience of BWT in the UK.

OVERVIEW OF THE WATER SOFTENING PROCESS
WHAT IS A WATER SOFTENER?
Soft water
Hard water
A water softener works by passing hard
water through a cylinder containing ion
exchange resin.
Resin
The resin consists of tiny beads that attract
and retain the hardness minerals, allowing
the now softened water into your
household water supply.
Brine
SOFTENING CYCLE
Periodically, these resin beads are
automatically cleaned and regenerated by
rinsing with a small amount of brine, (a salt
solution).

INSTALLATION AND
OPERATING CONSIDERATIONS
1. Before you begin
The installation of your new water softener is relatively straightforward. However, we
would recommend that either a qualified plumber or a person with relevant plumbing
experience carries out the installation.
Before embarking on the installation, please ensure you have familiarised yourself with
both these instructions and the components required to complete the installation.
2. Positioning the water softener
Please measure your water softener to ensure that it will fit into the area in which you are
placing the unit. PLEASE remember to include additional space for connecting pipe work
in your calculations along with the regular access that is needed for topping the unit up
with salt and future service.
Where possible, the distance of both the incoming water supply and nearest drain should
be kept to a minimum. Two metres is an ideal distance, however, longer distances are
permissible, dependant on the incoming water pressure.
Please remember the weight of your new water softener will considerably increase once
installed and filled with salt. Therefore, please ensure your chosen location is strong
enough to support an approximate total weight of 50 Kg.
Your new water softener has been designed to operate efficiently and effectively with an
incoming water pressure of between 1.7 to 5 BAR. If your water supply is likely to fall
outside these limits, then we would recommend that a booster pump or pressurelimiting valve should be fitted respectively.
PLEASE NOTE: UK Water Regulation guidelines on the installation of water softeners indicate that a minimum of one tap
is left as a source of untreated water / drinking water within the home. It is also recommended that any garden taps should
also be left untreated.
If the property is to be left unattended for any length of time e.g. holidays, the water softener should be bypassed /
isolated from the mains water supply by reversing the 3 valve positions as shown in the installation diagram on page 8.
After prolonged periods of non-use, ensure inlet and outlet valves are open and bypass valve is closed and start a manual
regeneration as described on page 14.
Important - do not install the water softener where it, or its connections (including the
drain overflow lines) will be subject to temperatures under 5ºC or above 40ºC.
664
3. Loft installation
The water softener should be installed within a container with no less than 100 litre
capacity, to which there should be connected an overflow pipe of no less than 20mm
diameter. The overflow should be connected at the bottom of the container and not less
than 150mm below the height of any electrical components mounted on the water
softener. It is recommended that an anti-vacuum valve be fitted to the inlet pipework
supplying the water softener.
4. Plumbing systems
There are several types of plumbing systems in common use:
a) Static Head
These systems are fitted with storage tanks. The water softener can be installed using the
standard 15mm or 22mm installation kit supplied with your water softener.
b) Systems using combination boilers (15mm)
For these systems, we recommend that your water softener be “hard plumbed” using
copper tubes or flexible high flow braided hoses.
c) Unvented fully pressurised systems (22mm)
As for combination boilers above.
5. Backflow prevention device
When fitted to the supply feeding a single dwelling, a check valve complying with BS6282
Part 1 must be fitted on the cold water feed prior to the installation. All other types of
installation require the fitting of a double check valve.
6. Drinking water
Your water softener installation must include at least one drinking water tap that is not
fed by the water softener.
It is recommended that individuals on a low sodium diet should follow the Department of
Health's advice that water from a domestic water softener should not be used for
drinking or cooking. Softened water contains a small amount of sodium. It has been
calculated that 1 pint of softened water contains a similar amount of sodium as two slices
of white bread or ¼ pint of milk.
Water that is used for mixing powdered milk for babies must only be taken from an unsoftened mains tap as some powdered milks and softened water both contain sodium for
which young babies have a limited tolerance.

4. Overflow connections
Rigid plastic 3/4" overflow pipe (not supplied with the softener) should be connected to
the push fit elbow at the rear of the cabinet (see page 8). Run the pipe downhill to the
outside of the building. Take care that the overflow does not discharge where damage
could occur.
If the water softener is fitted in a cellar or basement, the overflow can be run to a
storage tank. Do not elevate the overflow hose. Do not use jointing cement on the fitting.
5. Electrical connections
For added safety, peace of mind and ease of installation, your water softener is powered
by low voltage via a plug in transformer. This transformer must be connected to a
switched socket. Plug the transformer into the socket with the switch in the OFF position.
6. Filling the brine cabinet, salt usage and the salt alarm
Now place the water softener salt in the brine cabinet. Use care cubes (tablet salt)
only, this is available from your local BWT stockist.
Note: Tablet salt or block salt can be used for the WS455 and WS555 models, depending
on preference.
Notes on salt usage
Your water softener will only perform effectively if there is salt in the brine cabinet during
the regeneration process. It is therefore essential that the salt level does not fall lower
than 150mm in depth when measured from the base of the brine cabinet.
Note: The softener requires no priming. Do not add water to the brine tank.
During regeneration, salt will not enter your water system as the salt used in the
regeneration process is rinsed safely away to drain.

7. Blending control
All machines are factory set to produce
water that is soft. If you prefer water which
is less soft, turn the blending knob on the
left side of the valve anti-clockwise until
the water meets your requirements.

9. Switching on for the first time
" Check that the inlet / outlet hoses or couplings are properly connected i.e. inlet-to-inlet,
outlet-to-outlet.
" The by-pass arrangement should be in the open position i.e. the inlet and outlet valves
closed, by-pass valve open. Mains stop valve open.
" Check that the brine cabinet contains salt.
" Check that the water softener is connected to the drain and the overflow pipe is
connected. The drain and overflow must not be linked to each other.
0:00
Lift off this cover and connect the
jack plug of the power lead to the
control box behind the front panel
" Gently open the inlet valve so that water flows into the resin vessel.
" Switch on the power, you will hear the valve move quietly into the start position. When
the positioning process has been completed (which can take up to 10 minutes), you
will hear the movement stop. The valve has now reached its start position in
preparation for the programming procedure.
" Close the by-pass valve.
" Gently open the outlet valve.
" Check for leaks, take corrective action to stop leaks if required.
" Your water softener is now on line and you may start the valve programming procedure
set out in the next section of this manual.

PARTTWO
8. Testing for the water hardness in your area
Water hardness can vary from one location to another. To determine the hardness of the
water feeding your water softener (un-softened supply), use the hardness test kit supplied.
" Fill the test bottle supplied to the fill line with water from a hard water tap.
" Add the tablets to the solution one tablet at a time.
" Shake the bottle in between and keep adding tablets to the water until the solution turns
from wine red to blue, record the number of tablets as you go.
" Using the data table supplied with your kit, match up the number of tablets with the
hardness. You will need this figure when programming your water softener in the next
section of this manual.

RECHARGE Time
1. SETTING THE TIME OF DAY (see Fig1)
The first two digits (00) of the display will flash, prompting the installer to set the time.
The time is adjusted by using the
keys. Pressing the
key enters the hours.
The minutes are set by using the
keys.
Pressing the
key once enters the minutes and moves the display into the Set
Hardness mode.
2. SETTING THE WATER HARDNESS (see Fig2)
The display default is 300 (typical hardness level) which indicates a setting suitable for
hard water with a value of 300 parts per million of hardness minerals. Use the
keys to adjust the setting to match that of the one you obtained / identified earlier. See
page 11 for details.
Pressing the
set key once enters the hardness and moves the display to Set
Recharge Time Mode.
3. SETTING THE RECHARGE TIME (see Fig3)
To operate effectively, your water softener needs to regenerate periodically (dependent
on the hardness of the supply and amount of water used). The default time of day when
this is to occur is 2.00am. To alter this setting, use the
keys.
Pressing the
key once enters the recharge time and returns the display to Normal
Operation Mode and no further adjustment of the water softener is required.
12
12
Pressing the button will return the display to the Normal Operation mode.
Programming is now complete and now further adjustments of the water softener is
required.
Remember to check the salt and water level in the brine cabinet weekly.
5. Charge Bar
Having set the display on the control panel, you will notice that during normal operation,
there is a charge bar running along the bottom of the display. This charge bar shows the
percentage of water softener capacity remaining since the last regeneration. Immediately
following a regeneration, the charge bar returns to 100%.
6. Resetting the display during normal operation.
If the time is to be adjusted during normal operation, press any key to illuminate the
key once. The display will flash and indicate present time. Using the
display, press the
keys will alter the time as described on page12.
7. Power loss
The AMECS system will maintain the individual programming parameters of the water
softener for up to 72 hours.
If the power cut lasts longer than 72 hours, the control will flash "0:00" when power is
returned to the control. The unit will continue to keep time from the moment power is
restored. In this situation, the time of day will need to be reset.
8. Flow indicator
During normal operation, a flow indicator will flash on the display at a rate of one litre per
pulse when water is passing through the softener.
9. Cleaning
Your water softener may be cleaned using a damp cloth and a mild detergent. Do not use
bleaches, solvents or spirits as they may damage the surfaces.
13
13
PART THREE
4. Setting the Type of Salt. (See Fig4) *For WS455 and WS555 models only
To operate effectively, your water softener must be set to the type of salt that you intend to
use in the system. Block salt (BS) and care cubes (CC) are suitable. Use the
keys to select the type of salt used.
PART THREE
10. Manual regeneration ( )
Under normal operating conditions, your water softener will regenerate automatically and
you should not normally have to regenerate the unit manually. If, however, a manual
regeneration is required, then follow the procedure set out below.
1. Press any key to illuminate the display.
2. Momentarily pressing the
button (symbol underneath the display and furthest to
the right) will illuminate Recharge Tonight on the display and perform a regeneration at
2.00a.m. regardless of the remaining water softener capacity.
3. If the
button is subsequently pressed, this will clear the Recharge Tonight indicator
from the display and cancel the Recharge Tonight feature.
4. If the
is pressed down for approximately six seconds, the controller will flash the
Recharge display and immediately commence the regeneration cycle which cannot be
cancelled once started.
11. Salt usage
Your water softener is controlled by a microprocessor which constantly monitors water
usage. The system will build up a history of your water requirements and calculate the
most economical regeneration pattern. This will ensure a constant supply of softened
water whilst maintaining high levels of water and salt efficiency. As your water softener
uses a proportional brining system, more frequent regenerations do not necessarily
mean high water / salt usage.
12. Increase in number of residents
Sudden changes in your water usage should not affect your water softeners
performance. If, however, the number of guests staying with you increases, you will
notice that the water usage patterns will alter. This may cause your water softener to
regenerate more often than normal. As the water usage returns to its normal level, the
number of regenerations will also return to normal.
13. Cabinet Water Level
During normal operation, the water level inside the water softener cabinet will rise and
fall as required by the regeneration process. If the water softener is used within the
specified operational parameters, the water level should not reach the overflow
connection. If, however an overflow situation occurs, please refer to the troubleshooting
section on page 15 to diagnose the problem.
Following any overflow situation, reduce the water level by half and initiate a manual
regeneration as described above.
Note: Check the water level weekly and following any unplanned event, e.g. power
failure.

Notes
* Flow rates are from 10 and up to a peak of 50 litres / min. At flow rates under 10 litres /
min, the hardness may not be effectively removed from the water. If peak flow rates are
sustained for longer than 10 minutes, the softener capacity may be reduced resulting in
hard water breakthrough.
**The proportional brining control system calculates the exact amount of water and salt
required to regenerate the water softener. The amounts used will vary depending on water
usage patterns.
