1. General Notes

The SoftH2O-DUO water softeners are a range that utilise two resin pressure vessels. Compared to standard single pressure vessel water softeners, this setup guarantees 24/7 access to soft water. Whilst one pressure vessel is in service, the other one is either in standby or in regeneration. The automatic valve monitors the amount of water going through the softener and triggers regeneration when the softening capacity of one pressure vessel expires. This manual is for a

range of softeners based on the eck 9000/9100/9500 with various volumes of resin going from 30 to 350 litres.

Please take a look at the model supplied as this will have an inuence on various parameters for starting up your

softener, especially during programming. Once installed softeners are low in maintenance and only require a top up of

salt in order to operate properly. Please ensure that the brine tank has got a minimum level of salt at all times. Although

the original valve manual is included, it is preferable to use this O.E.M. manual as all settings and information will be

adapted to the conguration of your specic system.

Component Features Functions

Automatic

Control Valve

• FDA approved Noryl plastic

• Strong corrosion resistance

• Innovative design

• 24 hours control and monitoring with a timer; automatically regenerates the media bed at the system’s set time of regeneration according to the set regeneration frequency.

• Automatically calculates a cycle plan according to the quality of supply water and the user’s actual water use.

• Cycle Process:

In service: Once the water is supplied with correct pressure

and ow, the cations contained in hard water will be replaced by Na

in regenerants, then the softening system will supply

softened water through its outlet.

Backwash: When the ion exchange resin has been exhausted, the resin bed needs to be regenerated. Before the regeneration of the resin bed, a backwash step is necessary for two main purposes; removing the residue in the resin bed and loosening the impacted resin bed for

better regeneration efciency.

Rinse: Rinse the resin bed to remove the residual regenerant (salt) after the brining step until the water from outlet contains no regenerant; rinse could also compact the resin bed for a better softening effect.

Rell: Rell the brine tank with water to dissolve salt for the

next regeneration.

5. Installation Instructions

Water Pressure 2 - 8 bar

Electrical Supply Uninterrupted AC

Existing Plumbing Free of any deposits or build-ups inside pipes

Softener Location Locate close to drain & connect according to plumbing codes

Bypass Valves Always provide external bypass valve

The DUO water softener should be

installed and prepared by a qualied

person.

The system should be ready to use after the complete installation and a regeneration test. Any other operations are not necessary unless power supply is cut off accidentally.

• The softener needs to be installed onto the mains water supply. Piping has to comply with the regulations of the country where it is installed.

• The softener will require space for maintenance and operation. Please allow enough room on the top to remove the valve should it be needed. Also ensure access to the valve is clear in order to be able to visualise or adjust settings on the electronic board.

• The softener should be installed on a dry at surface.

• The softener uses mains power 230-240V AC 50Hz which is transformed into 24V DC. Please ensure that the electrical supply is protected from water or extreme conditions. All electrical installations have to comply with laws of the country in which it is installed.

• The water needs to have a pressure between 2-8 bar and 4-42 degrees Celsius.

• For residential purposes, it is essential to ensure that at least one drinking water tap is not connected to the softener. Softened water has a high Sodium content which is to be avoided for people on low sodium or salt diets, babies on infant formulas.

5.1. Connecting

1. Two drain connections will be required. The rst drain should be connected directly to the valve. (For

the 9000/9100 a ½”hose, for 9500 a ¾” BSP). The diameter of the exible drain hose should be able to accommodate the ow of water to the drain.

N.B. if the water cannot ow to the drain properly, the performance of the softening system will be affected. The drain should never be connected at a point higher than the softener as the back pressure will again affect ow.

2. The second drain should be connected to the brine tank over ow elbow. This is in place to ensure that if for

any reason the brine tank should overll the excess is sent to the drain. The diameter of the exible hose should be able to accommodate the ow and the outlet should not be connected above the height of the system.

N.B. the softening system should be connected with an external bypass in order to allow the system to be taken ofine without affecting water supply elsewhere.

N.B. any joint work or metal work should be completed prior to installation of the softening system.

6. Assembly & Start-Up

6.1. Assembly

1. Place the riser tube inside the  rst pressure vessel. Depending on the size of the vessel, the system will either be

supplied in a classic cone shape con guration or, for larger vessels, a star-type distribution system. Assemble the

star type distribution system if applicable.

2. Centre the distribution system inside the vessel and seal the top of the riser tube to ensure that no resin enters

the distribution system.

3. Fill the vessel (up to 85%) with the softening resin, ensuring that the distribution system remains upright and

central.

N.B. a funnel is recommended to aid the  lling process and prevent excess resin from being spilt.

CAUTION: Resin can present a serious slip hazard if excessive amounts are spilt.

4. Lubricate the internal valve O-ring with 100% silicon lubricant and screw the valve onto the top of the pressure

vessel, again making sure that the distribution system locates securely into the valve body.

5. Repeat steps 1-4 for the secondary (slave) vessel.

6. Connect one end of the brine tube to the valve and the other end of the brine tube to the safety brine valve

located inside the brine tank. (The tubing should be secure to ensure that no air enters the system).

On the side of the motor there is a diagram which illustrates various information regarding the valve’s regeneration cycle. The top arrow indicates the regeneration cycle. The bottom arrow indicates which tank is in service. This information will have to be entered during the valve programming.

6.2. Valve’s Regeneration Cycle

Spectrum

6. Assembly & Start-Up

6.3. Start-Up

1. Fill the brine tank until the water reaches approximately half way up the tank.

2. Add salt until the tank in total is approximately ¾ full.

3. Switch on the electrical power .

N.B. If the valve has a bypass function, place the system in the bypass position.

4. Turn on the mains water supply.

5. Open a cold soft water tap nearby and allow to run until all foreign material has been removed from the system.

6. Once clean, close the soft water tap.

7. Move the bypass in service position and allow water to  ow into the pressure vessels.

8. Open a cold soft water tap nearby and allow to run until the system has been purged of air.

9. Plug the valve into a power source. Once the valve has been connected to a power source, it may cycle on its

own in order to return to the service position.

10. Start regeneration by pressing the button on the controller and to bring the 2nd (slave) vessel into service.

Run through the cycle programmes in order to empty residual air in the  rst vessel.

11. Repeat step 10 for the second vessel.

12. Once complete, press and allow the valve to go through a full cycle independently.

Operation

7.1. Timer Operation

Features of the SXT:

• Power backup that continues to keep time and the passage of days for a minimum of 48 hours in the event of

power failure. During a power outage, the control goes into a power-saving mode. It does not monitor water usage during a power failure, but it does store the volume remaining at the time of power failure.

• Settings for both valve (basic system) and control type (method used to trigger regeneration).

• Day-of-the-Week controls.

• While in service, the display alternates between time of day, volume remaining or days to regeneration, and tank

in service (twin tank systems only).

• The Flow Indicator  ashes when outlet  ow is detected.

• The Service Icon  ashes if a regeneration cycle has been queued.

• Regeneration can be triggered immediately by pressing the Extra Cycle button for  ve seconds.

• The Parameter Display shows the current Cycle Step (BW, BF, RR, etc) during regeneration, and the data display

counts down the time remaining for that cycle step. While the valve is transferring to a new cycle step, the

display will  ash. The parameter display will identify the destination cycle step (BW, BF, RR, etc) and the data display will read “----”. Once the valve reaches the cycle step, the display will stop  ashing and the data display

will change to the time remaining. During regeneration, the user can force the control to advance to the next cycle step immediately by pressing the extra cycle button.

13. Cautions

1. Without reading and understanding the contents of this user manual, DO NOT perform any operations on the

control valve.

2. Strictly prohibit a leaning position when shipping, installing and using this product as this could cause damage.

3. During the regeneration, water from the tap will NOT be softened. It is NOT recommended to use water during

regeneration; otherwise a negative effect on the regeneration result will occur.

4. Initiate a regeneration cycle when the softener has been inactive for a long period of time and then turn on the

tap for several minutes before resuming normal use.

5. Do not disconnect power during service to prevent timer distribution.

6. If water usage or hardness of raw water dramatically increases (compared to the normal usage), then the frequency

of regeneration should increase.

7. Hot water could cause severe damage to the softener system, for water boiler and water heaters users, ensure the

total-run of the piping between the softener and the boiler is not less than 3 meters. It is recommended to install

a check valve between the lter and the boiler if unable to meet the required piping length.

8. The input water pressure must be between 2 - 8 bar.

9. No chemicals should be present at the inlet and outlet connecting sectors.

10. Besides the system, spare part connection materials are not included in the scope of the manufacturer’s warranty.

11. The required environmental temperature for a softener is 1 - 42°C. Below this will cause the softener to malfunction.

12. Do not apply pressure to the softener.

13. Indoor installation is preferred. Avoid exposure to direct sunlight, radiation from other heating sources and avoid

extreme weather conditions including rain and snow.

14. Use salt granules or tablets designed for softeners.

15. No tools should be used for connecting the plastic parts as over tightening or excessive force could result in

damage.

16. If necessary use food grade silica sealant for lubricating rubber O-rings.

17. Only qualied personnel should adjust or remove the adaptor locking clips on the reverse of the valve, as this can

tamper with the valve settings. Should this be required pressure must rstly be discharged from inside the water

softener.
