OVERVIEW OF THE WATER SOFTENING PROCESS
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.

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 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.
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 when choosing a location for your new water softener the weight will considerably increase once installed and filled with salt.
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.
Important - do not install the water softener where it, or its connections (including the o
4
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.
3. L o f t i n s t a l l at i o n
The water softener should be installed within a container of not less than100 litre capacity, to which there should be connected an overflow pipe of not 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:
Static Head, These systems are fitted with storage tanks. The water softener can be installed using the standard 15mm installation kit supplied with your softener.
Systems using Combination Boilers (15mm), (HI-FLO systems) For these systems, we recommend that your water softener be “hard plumbed” using copper tube or the flexible high flow braided hoses supplied with a HI-FLO softener.
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.

PART TWO
INSTALLING YOUR WATER SOFTENER
1. Positioning the water softener
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 pressure, then a pressure-limiting valve should be fitted.
Where the pressure is less than 1.7 BAR a booster pump may be required.
2. Inlet and outlet connections
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 in one of three ways - where high flow rates are not required
(static head systems) these connections can be made using the standard flexible hoses supplied with your softener, ensure the hoses are not kinked as this may restrict flow. For systems requiring higher flow rates (those fitted with combination boilers or unvented pressurised systems) the connections should be made using specialist high flow hoses supplied with a HI-FLO softener, or conventional copper tube and fittings.
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
o
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.

4 . O ve r f l ow c o n n e c t i o n s
An overflow pipe should be connected to the push fit elbow at the rear of the cabinet
(see page 6). 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.
Do not join the overflow and drain hose.
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 fused switched socket. Plug the transformer into the socket with the switch in the OFF position.
6. Filling the brine cabinet and salt usage
Now place the water softener salt in the brine cabinet. Use tablet salt only, this is available from your local Liff dealer.
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.
N.B. The softener requires no priming, add no 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.

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.
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.
00:00
Slide the front cover forward 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.

9. Manual Regeneration ( button)
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 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 the programmed time regardless of the remaining water softener capacity.
I3. 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 button is pressed down for three seconds, the controller will flash the
Recharge display and immediately commence the regeneration cycle which cannot be cancelled once started.
10. 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 (volumetric models), more frequent regenerations do not mean high water / salt usage.
11. 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 that normal. As the water usage returns to its normal level, the number of regenerations will also return to normal.
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
13 to diagnose the problem.
Following any overflow situation reduce the water level by half and initiate a manual regeneration as described above.
NB: Check the water level weekly and following any unplanned event, e.g. power failure.

4. If the button is pressed down for three seconds, the controller will flash the
Recharge display and immediately commence the regeneration cycle which cannot be cancelled once started.
10. 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 (volumetric models), more frequent regenerations do not mean high water / salt usage.
11. 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 that normal. As the water usage returns to its normal level, the number of regenerations will also return to normal.
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
13 to diagnose the problem.
Following any overflow situation reduce the water level by half and initiate a manual regeneration as described above.
NB: Check the water level weekly and following any unplanned event, e.g. power failure.

Notes
* Hardness may not be effectively removed from the water at flow rates under the minimum flow rate as stated above. If peak flow rates are used for longer than 10 minutes the water 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. Timed control softeners have no proportional brining, salt usage will therefore be as stated in the above table, (Salt / regeneration max.).
