Pressing the [SET] key once enters the recharge time and moves the display into Set Salt Type Mode.

This option is only available on certain models not standard

3. Installation

3.1 Installation requirements

National guidelines and regulations:

Observe all applicable installation regulations, general guidelines, hygiene requirements, and technical specications. The hard water to be fed into the unit must always meet the specications of the national Drinking Water Ordinance or EU Directive 98/83/EC. The total dissolved iron and manganese may not exceed 0.1 mg/l. The hard water to be fed into the unit must always be free of air bubbles.

Frost protection and ambient temperature:

The installation site must be free of frost and kept free of chemicals, paint, solvents and fumes. The ambient temperature should not exceed 40°C, even before the machine is started. Please avoid direct heat sources, e.g. radiators and exposure to sunlight.

General safety:

The rated mains power (see technical data) and the requisite inlet water pressure must be present at all times. No protection against a lack of water is provided. This must be installed on-site if required.

Overpressure and uctuation protection:

Attention: Water pressure must never exceed the unit‘s maximum of 5.0 bar UK, 8.0 bar EU. If the network water-pressure is higher than 4.0 bar UK, 6.0 bar EU (or you are unsure about pressure),

a pressure reducer (pressure reducing valve) must be installed upstream of the unit.

During pressure fuctuations or surges, the sum of the pressure surge and the standing pressure is not to exceed the nominal pressure.

Electrical interference:

The emission of interference (voltage peaks, high-frequency electromagnetic elds, interference voltages, voltage fuctuations…) by the surrounding electrical systems may not exceed the maximum values specied in EN 61000-6-3.

Data analysis of the hard water in your area:

Continuous operation of the water softener with water containing chlorine or chlorine dioxide is possible if the concentration of free chlorine/chlorine dioxide does not exceed 0.5 mg/l.

The type of pre-treatment must be determined individually.

Principle of intelligent regeneration:

The unit should be sized according your current water consuption. If water consumption is reduced, e.g. during holidays, a shut-off device must be fully opened for at least 5 minutes before water can be used again.

Inlet- and outlet connections:

When installing the unit, select a location where the unit can easily be connected to the water supply network. A connection to the waste water system (at least DN 50), a oor drain and a separate mains socket (see technical data) must be nearby.

Overow hose connection:

A suitable overow hose connection is required to remove the waste water.

Preconditions for the hydraulic installation:

Observe the hydraulic and electrical requirements for installation for rst commission. (see “chapter 5”)

Exclusion of warranty: Non-compliance with the installation conditions and the operator responsibilities voids the warranty.

Guarantee:

In the event of a malfunction of the unit during the guarantee period, please contact your after-sales service department and quote the model type and the production number (see technical data or the rating plate on unit). Note: Only your local after-sales service staff may perform any works under the guarantee. Any work performed by a third party must be directly commissioned by your after-sales service.

3.2 Initial commissioning

for professional installation by a qualied tter.

- Has all packaging material (16) been removed

from the brine cabinet?

- Is there a protective lter upstream from the

unit in the immediate vicinity?

- Is the water and power supply to the unit conti-

nuous (network pressure of at least 1.7 bar UK

/1 bar EU)

- Have you opened the pressure reducing valve to the limit stop?

- Have the water hoses been properly connected?

- (Observe the ow direction arrows and hard water inlet at the non-return valve of the unit).

- Have the drain water hose and the overow been routed separately to the waste water system and connected? (See Installation)

- Have you informed the operator of the ins- pection schedule? (Check supply of salt and hardness of blended water at least every two months)

- Have you informed the operator of the main- tenance schedule? (Tasks in accordance with manufacturer’s instructions. Interval annually, every 6 months with communal units)

Please check connections and pipeline junctions for leaks.

Handing over the unit to the operator:

If there is a delay between the installation/startup of the unit and transfer to the operator, a manual regeneration must be performed. The operator must be told how the unit works as well as how to operate and inspect it. Ensure that the operator receives the installation and operating manual.

3.3 Installation and operation considerations

1. Before you begin

The installation of your new water softener is relatively straightforward. However, we would recommend that either a qualied 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 t 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 considerably increase once installed and lled with salt. Therefore, please ensure your chosen location is strong enough to support an approximate total weight of (see table). Your new water softener has been designed to operate efciently and effectively with an incoming water pressure of between

1.7 to 5.0 bar UK, 1.0 to 8.0 bar EU. If your water supply is likely to fall outside these limits, then we would recommend that a booster pump or pressure

reducing valve should be tted respectively.

Important - Never install the water softener where it, or its connections (including the drain overow lines) will be subject to temperatures under 0°C or above 40°C. 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.

Do not operate with a pressure less than:

1.7 bar UK / 1.0 bar EU

If pressure more than:

5.0 bar UK / 8.0 bar EU install pressure reducing valve

Operating pressure

3.5 bar UK /

4.5 bar EU

3. Loft installation

The water softener should be installed within a container of not less than 100 litre capacity, to which there should be connected an overow pipe of not less than 20 mm diameter. The overow should be connected at the bottom of the container and not less than 15 0mm below the height of any electrical components mounted on the water softener. It is recommended that an anti vacuum valve be tted to the inlet pipework supplying the water softener.

4. Plumbing systems

There are several types of plumbing systems in common use: For 15 mm pipework (e.g.Static Head systems) The water softener can be supplied optionally with a high ow installation kit and exible high ow hoses suitable for 22mm pipework, for 15 mm pipework use the reducing bushes supplied with the kit, (see diagram on page 11).

5. Backow prevention device

When tted to the supply feeding a single dwelling, a check valve complying with national regulations must be tted on the cold water feed prior to the installation. All other types of installation require the tting 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. In case of low sodium diet follow the local “department of health‘s“ advice concerning the use of softened water for drinking. Note: 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.rer. Original spare parts and accessories authorized by the manufacturer guarantee operational safety. Using non-authorized parts may void any liability on the part of the manufacturer in case of consequential damage.

3.6 Installing your 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 5.0 bar UK, 8.0 bar EU or if you are unsure about pressure, then a pressure reducing

valve should be tted.

Where the pressure is less than 1.7 bar UK, 1.0 bar EU 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 conrm the direction of ow. Connections can be made with either conventional copper tube and ttings or the high ow exible hoses supplied, ensure hoses are not kinked as this may restrict ow.

3. Drain connection

Push the exible drain hose onto the barbed connector (Drain) as shown on page 7 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 20 mm. Softened water will have no adverse effect on a septic tank. You can extend the drain up to 9m if you have sufcient pressure (greater than 3 bar). The drain hose must not be kinked or restricted in any way as this will cause an overow 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 overowing.

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. Overow connections

The hose barb overow pipe (not supplied with the softener) should be connected to the push t elbow at the rear of the cabinet (see page 9). Run the pipe downhill to the drainage. Take care that the overow does not discharge where damage could occur.

If the water softener is tted in a cellar or basement, the overow can be run to a storage tank. Do not elevate the overow hose.

Note: Do not use jointing cement on the tting.

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. Attention: Plug the transformer into the socket with the switch in the OFF-position.

6. Filling the brine cabinet, salt- usage and alarm

Now place the water softener salt in the brine cabinet. Use the care cubes (tablet salt) or block salt (UK), from your local 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 re-

quires 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.

Salt alarm is optional - not standard on most models.

Depending on your model your water softener may be equipped with a low salt alarm, this monitors your salt usage and sounds an audible alarm while displaying the low salt error code “SALt“ when your salt levels falls to the minimum level. To reset the salt

alarm ll the system with salt and press the SET-key.

7. Blending control

All machines are factory set to producewater that is soft. Note: If you prefer water which is less soft, turn the blending knob on the left side of the valve anticlockwise 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 (unsoftened supply) use the hardness test kit supplied.

- Fill the test bottle supplied to the ll 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 gure when programming your water softener in the next section of this manual.

9. Switching on for the rst time

- Check that the inlet hoses and outlet hoses or couplings are properly connected i.e. inlet-to-

inlet, outlet-to-outlet.

The by-pass arrangement (see page 09) should be in the open position in example:

- the inlet- and outlet valves closed (E), (C)

- Check that the by-pass valve (D) open

- Check that the mains stop valve (F) open.

- Check that the Brine Cabinet (G) contains salt.

- Check that the water softener is connected

to the drain (H) and the overow pipe is be linked to each other connected.

Note: The drain and overow must not be linked to each other.

- Gently open the inlet valve (C) so that water ows into the resin vessel.

- Turn 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 5 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 (D).

- Gently open the outlet valve (E).

- 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.

4. Operation

4.1 Function

Capacity requirement-dependent of the unit controller:

The unit operates according to the principle of intelligent regeneration. The average capacity level of each model is preset and updates automatically to the actual consumption within 14 days.

The presetting is appropriate for the most common applications. It is not necessary to adjust the unit for individual requirements.

Intelligent quantity-dependent regeneration

When the unit is started, the available supply of softened water is programmed (depending on the hardness of the water). At a user-dened time (e.g. at night), the unit checks whether the remaining supply of softened water is sufcient for the following day. If this is not the case, the softening column is regenerated by only the exact percentage necessary to fully replenish the supply of softened water to 100%.

Note: With intelligent regeneration, the remaining supply of softened water is not wasted.

This intelligent regeneration method is possible because of the precision owmeter, which is able to adjust the amount of brine required for partial regeneration. The consumption of regenerative and water is reduced to the required minimum.

In the event of a power failure, the data and the time are retained (for approx 72 hours). The unit is optionally equipped with a device that disinfects the ion exchange resin during the regeneration. A spring-loaded non-return valve (18) is optionally available (see page 5).

Automatic regeneration triggering:

This is an optional setting - not as standard on all softeners.

4.2 Operation

Setting the Type of Salt used

To operate effectively, your water softener must be set to the type of salt you intend to use in the system.

The Care cubes are suitable.

Pressing the [SET] button will return the display to the Normal Operation mode. Programming is now complete and no further adjustment of the water softener is required. Remember to check the salt and water level in the brine cabinet weekly.

connect jack plug here

Lift off this cover and connect the jack plug of the lead to the control box behind the front panel

Charge Bar

Having set the display on the control facia, 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%.

Resetting the display during operation.

If the time is to be adjusted during normal operation, press any key to illuminate the display, press the [SET] key once. The display will ash and indicate present time. Using the keys will alter the time as described on page 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 hrs, the control will ash “00:00“ 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.

Flow indicator

During normal operation, a ow indicator will ash on the display at a rate of one litre per pulse when water is passing through the softener.

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.

Manual regeneration [recharge] 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 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 2.00 a.m. regar less 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 [recharge] button is pressed down for six seconds, the controller will ash the Recharge display and immediately commence the regeneration cycle which cannot be cancelled.

Adding regenerative

Rell the salt no later than when SALt is indicated on the display or 150mm above the base of the softener.

Acknowledge - low SALt alarm: NOTE: This function is optional - not standard on

all models. Open the cover (4). Pour regenerative into the storage area (5).

Press [SET] and hold until the SALt display goes out. Rell the unit in such a way that no dirt can get into the storage area (5) (if necessary, clean the packages containing the regenerative before use).

Clean the storage area or brine cavity (6) with clean water if it gets dirty.

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 efciency. As your water softener uses a proportional brining system, more frequent regenerations do not necessarily mean high water / salt usage.

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.

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 specied operational parameters the water level should not reach the overow connection. If however an overow situation occurs please refer to the troubleshooting section on page 17 to diagnose the problem.

Following any overow 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. powerfailure.

4.3 Setting the hardness of blended water

The unit is preset to 300 ppm. To test the water hardness, allow the nearest cold water tap to run for a while and check the hardness of the blended water using the AQUATEST hardness tester.

Adjust with the blending valve V until the desired value is reached.

5. Maintenance

5.1 Maintenance work

The operator must regularly perform the following checks to guarantee that the unit functions properly.

Check the regenerative and rell after use.

Check the water hardness: The hardness of drinking water and the set blended water hardness must be checked 2x annually and the hardness of the blended water must be corrected when required (see Start-up).

Check for leaks, visual inspection: Check connection lines and connections for leaks. Check for dirt in the regenerative storage area and brine cavity every two months and clean and ush with clear water if necessary.

The intervals between checks are recommended minimums and must be adjusted according to site conditions.

5.2 Operator responsibilities

All technical equipment requires regular servicing in order to guarantee optimal functionality.

Keep yourself up to date with regard to the quality and pressure ratio of the water which is to be treated. If the water quality changes, the settings may need to be changed. Consult a specialist if this is the case.

Regular checks by the operator are required for the warranty and proper functioning of the unit. The water softener must be inspected regularly in accordance with the conditions of operation and use.

Operator checks intervalls:

After use: Rell regeneration salt 2x Annually: Check pressure 2x Annually: Check water quality 1x Annually: Clean brine container

5.3 Maintenance & wearing parts

Wearing parts must also be replaced within the prescribed maintenance intervals in order to guarantee functionality and full the warranty conditions. The water softener should be serviced once

a year.

Wearing parts may only be replaced by qualied personnel (tters or after-sales service team). We recommend that you enter into a maintenance agreement with your tter or the aftersales service team.

Cleaning information: Do not use alcohol or alcohol based cleaning agents, otherwise the plastic surfaces of the device will be damaged.

5.4 Disposal

At the end of product life please contact BWT Customer Services to arrange a new replacement for your softener.

Disposal of your softener and any electrical parts should only be carried out at authorised WEEE recycling centres.
