WARNING & SAFETY INSTRUCTIONS

Page 3

 Before you begin the installation of the water filter, we advise you read

and carefully follow the instructions contained in this manual. It contains important information about safety, installation, use and maintenance of the product. The actual system that you have received, may differ from the pictures/illustrations/descriptions in this Technical Manual.

 Failure to follow the instructions could cause personal injury or damage

to the appliance or property. Only when installed, commissioned and serviced correctly, the water filter will offer you many years of troublefree operation.

 The water filter is intended to improve certain parameters of the water.

The water filter will not purify polluted water or make it safe to drink!

 Installation of the water filter should only be undertaken by a competent

person, aware of the local codes in force. All plumbing and electrical connections must be done in accordance with local codes.

 Before setting up the water filter, make sure to check it for any externally

visible damage; do not install or use when damaged.

 Use a hand truck to transport the water filter. To prevent accident or

injury, do not hoist the water filter over your shoulder. Do not lay the water filter on its side.

 Keep these Instructions in a safe place and ensure that new users are

familiar with the content.

 The water filter is designed and manufactured in accordance with current

safety requirements and regulations. Incorrect repairs can result in unforeseen danger for the user, for which the manufacturer cannot be held responsible. Therefore repairs should only be undertaken by a competent technician, familiar and trained for this product.

 In respect of the environment, this water filter should be disposed of in

accordance with Waste Electrical and Electronic Equipment requirements. Refer to national/local laws and codes for correct recycling of this water filter.

OPERATING CONDITIONS & REQUIREMENTS

Page 4

 APPLICATION LIMITATIONS:

 incoming pH: pHneutralizer: 6,0 - 7,0 pHneutralizerXL: 5,0 - 6,0

If the pH of the incoming water is below the stated levels, insufficient correction of the pH may occur, i.e. the pH at the outlet of the water filter may not be raised as expected.

 incoming hardness: max. 100 mg/L as CaCO3 (= 10 °f or 5,6 °dH); at higher

hardness levels the water filter will still function, but the filter media will become ‘caked’, reducing its lifespan; increasing the regeneration frequency (i.e. reducing the number of days between 2 regenerations) may prevent this from happening.

 outgoing hardness: as a result of the dissolution of the filter media, the water

hardness at the outlet of the filter will increase; a water softener may become necessary.

 OPERATING PRESSURE: min. 2,0 / max. 8,3 bar

 this system is configured to perform optimally at an operating pressure of 3

bar (±½ bar); in case of a higher operating pressure the performance may be affected negatively!

 if installed on a well, verify that the well pump is powerful enough to provide

sufficient flow rate for the regeneration cycle.

 check water pressure regularly.  install a pressure reducer ahead of the water filter if necessary.

 OPERATING TEMPERATURE: min. 4 / max. 38 °C

 do not install the water filter in an environment where high ambient

temperatures (e.g. unvented boiler house) or freezing temperatures can occur.

 the water filter cannot be exposed to outdoor elements, such as direct sunlight

or atmospheric precipitation.

 do not install the water filter too close to a water heater; keep at least 3 m of

piping between the outlet of the water filter and the inlet of the water heater; water heaters can sometimes transmit heat back down the cold pipe into the control valve; always install a check valve at the outlet of the water filter.

 ELECTRICAL CONNECTION: 230V-50Hz

 this water filter only works on 24VAC; it is equipped with a 230/24V-50Hz

transformer; always use it in combination with the supplied transformer.

 make sure to plug the transformer into a power outlet, which is installed in a

dry location, with the proper rating and over-current protection.

ASSEMBLY

Page 5

 For ease of transportation and installation, the filter

media is NOT loaded in the pressure tank, but delivered in separate bags of 1 Cuft; it must be loaded on-site, after positioning of the pressure tank.

 The gravel underbedding is already preloaded in the

pressure tank.

FILTER MEDIA LOADING

1. Move the pressure tank to the correct installation location; position it on a flat and level surface. Make sure to leave enough space for ease of service.

2. Position the riser assembly upright and centred in the pressure tank; plug the top of the riser tube with a piece of tape or clean rag, to prevent filter media from entering the tube.

3. Place a funnel on the pressure tank opening and fill the pressure tank with the filter media; make sure the riser assembly remains centered in the pressure tank.

4. Rinse the pressure tank opening to remove any filter media from the threaded section.

5. Unplug the top of the riser tube.

CONTROL VALVE

6. Make sure the O-ring in the riser insert and the tank Oring (around the threaded section of the control valve) are in the correct position.

7. Screw the top distributor onto the control valve.

8. Lubricate the threaded section of the pressure tank, the top of the riser tube and the tank O-ring of the control valve; use a silicon-based lubricant.

9. Lower the control valve straight down onto the riser tube, until the riser tube is correctly inserted in the riser insert; then push it down firmly and screw it onto the pressure tank.

INSTALLATION

Page 6

INLET & OUTLET

 Check the water pressure at the place of installation of

the water filter; it should never exceed 8,3 bar.

 We strongly recommend the use of flexible hoses to

connect the water filter to the water distribution system; use hoses with a large diameter in order to limit the pressure loss.

 If the water filter is not equipped with the factory bypass

(optional), we strongly recommend to install a 3-valve bypass system (not included with this product!) to isolate the water filter from the water distribution system in case of repairs. It allows to turn off the water to the water filter, while maintaining (untreated) water supply to the user.

WITH FACTORY BYPASS (optional)

Picture 1

 = mains water supply (untreated water)  = inlet of water filter (untreated water)  = outlet of water filter (treated water)  = house/application (treated water)

1. Screw the factory bypass onto the in/out ports on the control valve (&); make sure to install the gasket seals. Tighten the nuts firmly by hand.

2. Screw the connection kit with nuts onto the factory bypass (&); make sure to install the gasket seals. Tighten the nuts firmly by hand.

3. Connect the mains water supply to the adaptor on the inlet port of the factory bypass ().

4. Connect the house/application to the adaptor on the outlet port of the factory bypass ().

3. Connect the 3-valve bypass system to the adaptors on the in () and out () port of the control valve.

4. Connect the mains water supply to the inlet of the 3-valve bypass system ().

5. Connect the house/application to the outlet of the 3-valve bypass system ().

DRAIN

 We recommend the use of a stand pipe with air trap.  To prevent backflow from the sewerage system into the

water filter, always install and use the included air gap with double hose barb, to connect the drain hose to the sewerage system.

 Lay-out the drain hose in such a way that pressure loss

is minimized; avoid kinks and unnecessary elevations.

 Make sure that the sewerage system is suitable for the

rinse water flow rate of the water filter.

Picture 3

1. Install the air gap to the sewerage system; it fits over a 32 mm pipe or inside a 40 mm pipe adaptor. Ensure a permanent and watertight connection.

2. Connect a 13 mm hose to the drain connection of the control valve (); secure it by means of a clamp.

3. Run the drain hose to the air gap and connect it to one of the hose barbs; secure it by means of a clamp. This drain line operates under pressure, so it may be installed higher than the water filter.

ELECTRICAL

Picture 4

1. Plug the transformers output lead into the socket on the control valves power cord; secure it by means of the TwistLock clamp.

2. Plug the transformer into an electrical outlet.

START-UP

Page 7

PRESSURIZING

1. Make sure the bypass system is in 'bypass' position.

2. Make sure the electronic controller of the water filter is in service mode.

3. Open the mains water supply.

4. Open a cold treated water faucet nearby the water filter and let the water run for a few minutes until all air is purged and all foreign material that may have resulted from the installation is washed out; close the tap.

5. Gently pressurize the water filter, by putting it into service:

 factory bypass:

1. open the 'outlet' valve;

2. slowly open the 'inlet' valve.

 3-valve bypass:

1. close the 'bypass' valve;

2. open the 'outlet' valve;

3. slowly open the 'inlet' valve.

6. After 2-3 minutes, open a cold treated water faucet nearby the water filter and let the water run until all air is purged from the installation and the filter media is properly rinsed (it is normal for the rinse water to show some discoloration!); let the water run until the rinse water is clear; close the tap.

7. Check the water filter and all hydraulic connections for leaks.

 Calcium/magnesium will be added to the water when it

passes through the water filter, to raise its pH. As a consequence the hardness of the treated water will be raised also!

POWER-UP

After power-up, the power LED will light up and the display will show the installed software version, f.e.:

After 5 seconds, it will automatically revert back to the service mode.

POWER FAILURE

In the event of a power failure, the program will remain stored in the NOVRAM® during an undefined period, while an incorporated SuperCap (capacitor) will maintain the correct time of day during a period of several hours; consequently, in case of prolonged power failure, the time of day might not be maintained; if this happens, the time of day will be reset to 8:00 when the power supply is re-established, while the indication will flash, indicating that the time of day needs to be set.

When the power failure occurs during the execution of an automatic regeneration, the control valve will remain in its last position; when the power supply is re-established, the control valve will return to the service position, stay there for 60 sec. and restart a complete regeneration from the beginning.

TIMER FAILURE

In the event of a timer failure, the display will show the message:

If powering off/on the water filter doesn’t solve this problem, professional service is required.

SERVICE MODE

In service mode the display shows the time of day and the number of days remaining until the next regeneration:

REGENERATION MODE

In regeneration mode the display shows the remaining regeneration time and the remaining cycle time:

The control valve can be reset to service mode at any time by pressing the scroll  button, as such manually advancing it through the regeneration cycles.

MANUAL REGENERATION

It is possible to manually initiate a regeneration.

1. Press the scroll  button repeatedly until the display shows:

 If the control valve is left in this position, the

countdown timer will countdown to 0 sec and start a regeneration.

 To cancel this mode, press the scroll  button before

the countdown timer has reached 0 sec; the control valve will return to the service mode.

2. Press the scroll  button again if you want to manually advance the control valve to the next regeneration cycle.

DRIVE MOTOR SPEED

The drive motor of the control valve, that drives the valve body to its different regeneration positions, will start-up at low speed to reduce its noise level. To increase the speed of the drive motor, simply press the scroll  button as soon as the drive motor is activated.

ROUTINE CHECKS

Regularly the user should perform a basic check to verify if the water filter is functioning correctly, on the basis of the following control points:

1. Check settings of electronic control panel.

2. Check water composition before/after water filter.

3. Check drain line from control valve; there shouldn’t be any water flow (unless water filter is in regeneration).

4. Check water filter and surrounding area; there shouldn’t be any water leakages.

BYPASSING THE WATER FILTER

Occasionally it may be necessary to put the unit hydraulically in bypass, i.e. to isolate it from the water distribution system; f.e.:

 replenishment of filter media;  in case of an urgent technical problem;  when it is not necessary to supply treated water to the

house/application.

FILTER MEDIA

The filter media inside this water filter consists of 'selfsacrificing' minerals, that dissolve in the acidic water to raise its pH to neutral level. In order to maintain the optimum performance of the water filter, the filter media needs to be replenished regularly. Ideally the level of filter media inside the pressure tank is kept between 1/2 and 2/3 of the pressure tank height. The frequency of replenishment depends on the water usage and pH of the incoming water, but is typically once or twice per year.

Picture 8

The user should make sure there is always a sufficient amount of filter media in the pressure tank. Therefore he should periodically check the level of filter media and refill it if necessary. The easiest way to do this is by holding a bright light against the semi-transparent pressure tank, so that the top level of the filter media inside the pressure tank becomes visible.

If the level of filter media has dropped below the minimum level, the user should refill it.

1. Put the bypass system of the water filter in 'bypass' position.

2. Manually initiate a regeneration, by pressing the scroll  button repeatedly until the display shows:

3. Leave the water filter in this position; the countdown timer will countdown to 0 sec and start a regeneration.

4. Wait until the drive motor has driven the control valve in backwash position; the display will show:

5. Wait for 10-15 sec for the pressure inside the water filter to be relieved.

6. Unscrew the cap from the media fill opening on the pressure tank.

7. Via the media fill opening, pour filter media in the pressure tank as needed to reach the desired height.

8. Clean the threaded section of the media fill opening and screw the cap back on.

9. Manually initiate a regeneration, by pressing the scroll  button repeatedly until the display shows:

10. Put the bypass system of the water filter back in 'service' position.

SANITIZING THE WATER FILTER

This water filter is manufactured from premium quality material and assembled in safe conditions to assure it is clean and sanitary. If installed and serviced correctly, this water filter will not infect or contaminate your water supply. However, as in any 'device' plumbed-in in your water distribution system, a proliferation of bacteria is possible, especially in case of 'stagnant water'. Therefore this water filter will automatically rinse the filter media periodically.

If the power supply to the water filter is disconnected for a longer period of time, we recommend, when the power supply is re-established, to manually initiate a complete regeneration.
