WHAT IS A WATER SOFTENER?

A water softener works by passing hard

water through a cylinder containing ion

exchange resin.

The resin consists of tiny beads that attract

and retain the hardness minerals, allowing

the now softened water into your

household water supply.

OVERVIEW OF THE WATER SOFTENING PROCESS

BWT VOSFT Water Softener Dec 2015 20pp A5.indd 5 17/02/2016 08:45

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 you are placing

the unit into. 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 increase considerably 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 pressure-

limiting 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.

INSTALLATION AND

OPERATING CONSIDERATIONS

PART ONE

INSTALLATION AND

OPERATING CONSIDERATIONS

There are several types of plumbing systems in common use:

1) 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.

2) Systems using Combination Boilers (15mm) – For these systems, we recommend that

your water softener be “hard plumbed” using copper tube of flexible high flow braided

hoses.

3) Unvented Fully Pressurised Systems (22mm) –As for combination boilers above.

The water softener should be installed within a container with no less than100 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.

3. Loft installation

If you are planning to install the water softener above ground level e.g. In the loft,

the following instructions should be strictly adhered to.

4. Plumbing systems

5. Backflow prevention device

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 un-

softened mains tap as some powdered milks and softened water both contain sodium for

which young babies have a limited tolerance.

6. Drinking water

P RA T ENO

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.

TYPICAL INSTALLATION LAYOUT

It is very important to establish the water pressure before installing the water softener. If

the water pressure is low, then the water softener may not operate effectively. If it is too

high, then components inside the unit may be damaged.

Water pressure should be tested with a gauge at the kitchen tap or outside tap.

It should be noted that water pressure can increase at periods of low water usage e.g.

overnight. If, therefore, the daytime pressure exceeds 5 BAR or if you are unsure

about the pressure, then a pressure-limiting valve should be fitted.

Where the pressure is less than 1.7 BAR, a booster pump may be required.

PART TWO

INSTALLING YOUR WATER SOFTENER

2. Inlet and outlet connections

1. Positioning the water softener

With the bypass valve open and the inlet / outlet valves closed, the unit can be connected

to the plumbing system. Arrows on the inlet and outlet piping from the valve will confirm

the direction of flow.

Connections can be made with either conventional copper tube and fittings or the flexible

hoses supplied, ensure hoses are not kinked as this may restrict flow.

3. Drain connection

Push the flexible drain hose onto the barbed connector (Drain) as shown on page 6 and

secure with the clip provided. Run the drain hose to a stand pipe or to a drain. The air

gap needs to be at least 20mm . Softened water will have no adverse effect on a septic

tank. You can extend the drain up to 9m if you have sufficient pressure (greater than 3

BAR). The drain hose must not be kinked or restricted in any way as this will cause an

overflow from the brine cabinet.

Frost protection

If the drain hose or connecting pipework is likely to be subject to temperatures below 0 C,

it must be protected to prevent freezing. Failure to observe this precaution could lead to

the water softener overflowing.

Raising the drain hose

If you have a water pressure of 3 BAR or more, you can raise the drain to a maximum of

3 metres above the valve head.

TYPICAL INSTALLATION LAYOUT

It is very important to establish the water pressure before installing the water softener. If

the water pressure is low, then the water softener may not operate effectively. If it is too

high, then components inside the unit may be damaged.

Water pressure should be tested with a gauge at the kitchen tap or outside tap.

It should be noted that water pressure can increase at periods of low water usage e.g.

overnight. If, therefore, the daytime pressure exceeds 5 BAR or if you are unsure

about the pressure, then a pressure-limiting valve should be fitted.

Where the pressure is less than 1.7 BAR, a booster pump may be required.

INSTALLING YOUR WATER SOFTENER

2. Inlet and outlet connections

1. Positioning the water softener

With the bypass valve open and the inlet / outlet valves closed, the unit can be connected

to the plumbing system. Arrows on the inlet and outlet piping from the valve will confirm

the direction of flow.

Connections can be made with either conventional copper tube and fittings or the flexible

hoses supplied, ensure hoses are not kinked as this may restrict flow.

3. Drain connection

Push the flexible drain hose onto the barbed connector (Drain) as shown on page 6 and

secure with the clip provided. Run the drain hose to a stand pipe or to a drain. The air

gap needs to be at least 20mm . Softened water will have no adverse effect on a septic

tank. You can extend the drain up to 9m if you have sufficient pressure (greater than 3

BAR). The drain hose must not be kinked or restricted in any way as this will cause an

overflow from the brine cabinet.

it must be protected to prevent freezing. Failure to observe this precaution could lead to

10. Salt usage

As your water softener

uses a proportional brining system, more frequent regenerations do not necessarily

mean high water / salt usage.

11. Increase in number or 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.

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.

12. 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 on page 13.

NB: 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.
