2. General Notes
The SWS Simplex range of water softeners includes one pressure vessel containing resin, automatic valve and brine
tank. The amount of water going through the softener is monitored and regeneration is triggered when the softening
capacity of the pressure vessel expires. This manual is for a range of softeners using the SPECTRUM 7 valve with resin
volumes ranging from 100 to 250 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.
Water softeners will fall under laws and guidelines of the country where it is installed. Please check the current legal
framework in order to be compliant.
Articially softened water can have a high sodium content which can be unsuitable for babies on infant formula, people
on sodium restricted diets or people with risk of heart diseases.

control valve
• FDA compliant GRP valve
• Strong corrosion resistance
• Innovative design
• CE marked
• 24 hours control and monitoring with a timer and meter;
automatically regenerates the media bed once the
capacity of a pressure vessel expires
• 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
Valve Operation Mode Softener: Standard water softener operation

7. Installation Instructions
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.
Your softener will require space for maintenance and operation. Please allow enough room at the top of the system 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. It should be installed on a dry at surface.
The softener uses mains power 230-240V AC 50Hz which is transformed into 5.5V or 7.5V 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.
Inlet water
An inlet pressure between 2-8 bar is required with a temperature range of 2-42°C. For applications with an incoming
pressure under 2 bar a booster pump is required, over 8 bar, a pressure reducer must be tted before the softener. It
is recommended to add the necessary pre-ltration before the softener should the TSS (Total Suspended Solids) go
over 1ppm. Suspended solids could become trapped between the piston and seals and cause premature wear of the
internal mechanisms of the valve.
You will need two drain connections:
One is for the water rejected to the drain during the regeneration process. This will be connected to the valve, which
is dened as the drainline. Water volume and ow estimations are made in the technical data chart at the end of the
document. The diameter of the exible drain pipe should be able to accommodate the ow of water to the drain. If the
water does not ow to the drain properly, this will affect the performance of your softener. The drain should never be
higher than the valve height as the back pressure will affect the ow of the drain.
Secondly, you will need a connection going from the brine tank overow to the drain. Although your brine tank is
equipped with a safety brine valve, it is an extra measure to avoid damage caused by ooding.
Both the drain line and the overow should not be higher than the control valve otherwise, this will affect the softeners
performance.
The softener should be piped with an external bypass in order to be able to take it off the water line for maintenance
purposes. The soldering on the pipework has to be connected before the water softener as heating could damage the
water softener.
Put the riser tube assembly into the pressure vessel if it has been removed for transport and seal the top in order to
avoid resin getting inside of the riser tube. Depending on size, the riser tube assembly will either be supplied with a
cone type screen or for bigger sizes, a star type distribution system with a hub and laterals. Once the distributor tube
is centred, ll the pressure vessel with resin, lubricate the valve distributor tube O-ring with a 100% silicone lubricant,
locate riser tube in to valve distributor tube and screw valve on to vessel. Ensure that there is no resin on the tank
threads. It is preferable to use a resin funnel (PV-PK-Funnel) in order to efciently ll the pressure vessel.
RESIN IS SLIPPERY, REMOVE ANY EXCESS RESIN THAT MAY
HAVE BEEN SPILT

7.4. Start Up
Install the system in a convenient location. Ensure the oor under the brine tank is clear and at. Connect the brine tube
to the valve and the safety brine valve included in the brine tank.
Use PTFE tape if necessary in order to seal between the drain tting and the outlet ow control.
SPECTRUM 7 Valve
1. Build brine tank-place salt grid into base and connect brine valve etc.
2. Fill brine tank with water to top of brine grid. Set valve to manual regen and then skip process to brine rell mode.
Once this process has stopped add salt so that it is level or above water line.
3. Add salt until in total the brine tank is ¾ full.
4. For systems with a by-pass feature, place in by-pass position (Fig 1.)
5. Turn on the main water supply.
6. Open a cold soft water tap nearby and allow to run for a few minutes or until the system is free from foreign material
that may have resulted from the installation.
7. Once clean, close the water tap. Place the by-pass in service position and let water ow into the pressure vessel.
When water ow stops, slowly open a cold water tap nearby and allow to run until the air is purged from the unit.
8. Plug the valve to a power source.
9. Switch on the electrical power.
10. Once plugged the valve may do a cycle on its own in order to go to service position.
11. Start a regeneration by pressing and holding the [R] button on the controller for 3-5 seconds to go through a rst
complete cycle in order to initialise the system. This operation can last over an hour.

11. Cautions
1. DO NOT perform any operations on the control valve without reading and understanding the contents of this
manual.
2. Ensure the system does not lean during shipping, installation and use, as this is may cause damage.
3. During regeneration the water from the tap will NOT be softened. It is NOT recommended to use the water
during regeneration as this may have a negative effect on the cycle.
4. Initiate a regeneration cycle when the softener has been inactive for an extended 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 disruption.
6. If water usage or hardness of raw water dramatically increases (compared to the normal usage), then the frequency
of regeneration will 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 metres. 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 2-42°C. Outside these parameters may 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.
