1. General Notes
The MixH20 - Pro range of water conditioning systems includes one pressure vessel containing resin and an automatic
valve. 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 based on the SPECTRUM 5, 7 and 12 valve going from 25 to 350 litres of resin.
Please take a look at the model supplied as this will have an inuence on various parameters for starting up your
softener, especially on the programming side. Softeners once installed are low maintenance and only need salt in order
to operate. 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.
Articially 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.

• 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 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

6. Installation Instructions
6.1. Prerequisites
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 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.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 4-42°C. For applications with an incoming
pressure under 2 bar a booster pump would be required, over 8 bar, a pressure reducer should be tted before the
softener. It is recommended to add the necessary pre-ltration before the softener should the T.S.S. (Total suspended
solids) go over 1ppm. Suspended solids could be trapped between the pistons and seals and cause premature wear of
of the internal mechanisms of the softener.
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 dened 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 overow 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 overow should not be higher than the softening 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.
6.2. Assembly
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 in the inside of the riser tube. Depending on sizes, 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 and screw the valve onto the top of the pressure vessel. Ensure that there is no resin on the tank threads. It is
preferable to use a funnel in order to efciently ll the pressure vessel.
CAUTION: RESIN IS SLIPPERY REMOVE ANY EXCESS RESIN THAT MAY HAVE BEEN SPILT

6. Installation Instructions
Install the pressure vessel with the valve in a convenient location. Ensure the oor under the brine tank is clear and at.
Connect the brine tube to the valve on one side and to the safety brine valve included in the brine tank.
Use Teon® tape if necessary in order to seal between the drain tting and the outlet ow control.
6.3. Connecting
SPECTRUM 5 Valve SPECTRUM 7 & 12 Valves
6.4. Start Up
1. Half ll the brine tank with water.
2. Add salt until in total the brine tank is ¾ full.
3. For systems with a by-pass feature, place in by-pass position (Fig 1.)
4. Turn on the main water supply.
5. 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.
6. 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.
7. Plug the valve to a power source.
8. Switch on the electrical power.
9. Once plugged the valve may do a cycle on its own in order to go to service position.
10. Start a regeneration by pressing the [R] button on the controller to go through a rst complete cycle in order to
initialise the system. This operation can last up to an hour.

9. 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 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 1-42°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 qualied 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.
