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 inuence 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 conguration of your specic 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 efciency.
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.
Rell: Rell the brine tank with water to dissolve salt for the
next regeneration.
Valve Operation Mode Softener: Duplex water softener operation
Regeneration Mode Volumetric immediate with electronic timer

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 qualied
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 overll 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 ofine 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.
