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 flow, 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 efficiency.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.Refill: Refill the brine tank with water to dissolve salt for the next regeneration.

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

Brine tank set-up

1. Fill the brine tank with the required amount of salt. The salt levels should be higher than the water level for the initial installation. There should be enough solid salt at anytime throughout the life of the softener.

2. Manually initiate a whole regeneration cycle to fill water in the brine tank to an appropriate level.

The Chrono water softener should be installed and prepared by a qualified 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.

Important:It is recommended to install a bypass system to ensure there is a constant water supply, in the event of potential softener failure or maintenence.

1. Place the softener cabinet close to a drain where the system will be installed. The surface should be clean and level.2. Perform all plumbing according to local plumbing codes.

• Use a ½" minimum pipe or tubing size for the drain line. However use a ¾" pipe or tubing for backwash flow rates that exceed 32lpm (UK gal) or where length exceeds 20ft (6m).

3. Use PTFE tape on the drain fitting and any solder joints near the valve, before connecting any piping. Always leave at least 6" (152mm) between the valve and joints when soldering pipes that are connected to the valve. Failure to do this could cause damage to the valve.

4. The softener is supplied with 1" inlet adaptors to fit. Lubricate the O-rings on the quick connect screw adaptors. Remove the locking clips and push the adaptors in to the bypass, then refit the 2 locking clips. (See Fig. A)

5. Now set the valve into the bypass position (See Fig. B) using the tool provided, rotating the handles until they are both perpendicular to the flow path of inlet and outlet. This procedure only needs carrying out with the tool on the first operation, to release the valve from the factory setting.

6. Return the valve to the service position (See Fig. C).7. Into the brine tank add water until it is above the air check.

Do not add salt to the brine tank at this time.8. Open the main water supply valve slowly to the ¼ open position

and let the water flow into the resin tank. If the valve is opened too rapidly then the resin may be lost.

9. When all of the air has been purged from the tank, water will begin to flow steadily to the drain. Fully open the main supply valve.

10. Open a tap that is linked to the softening system and let water run for a few minutes or until the system is free of foreign material resulting from the plumbing work. Close the water tap when the water runs clean.

4. Installation Instructions

The softener needs to be installed onto the mains water supply. It has an integrated bypass. Piping has to comply with the regulations of the country where it is installed.• Do not plug in the electrical feed before the

installation.• Ensure the stopcock is closed.• The piping of the inlet and outlet are 1” BSP.• The water needs to have a pressure between 2-8

bar and 4-42 degrees.• The softener has to be installed on a flat dry surface.• Electrical mains powered 220-240V AC 50Hz.• The soldering on the pipework has to be done before connecting the water softener as heating could damage the

water softener.• 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, and babies on infant formulas.

4.1. Connecting

1. Close the stop cock.2. Connect the drain Line to the the outside drain of the premises. It is necessary to fit an air gap device.The drain

piping should be as short as possible avoiding height of over 1.5 metres higher than the softener as well as lengths of over 5 metres.

3. Connect the inlet and outlets to the fitted plumbing.4. Close the bypass valves. Open the stopcock and open the water at the feed tap. This will allow any particles

to be removed from the system before operation. Let water run out of the tap until it is clear. Once done, close both the outlet tap and the stopcock to pursue further steps of the installation.

5. Manually fill the brine tank with water between 5 and 10 cm.6. Open the bypasses as well as the stopcock . You will hear the water flowing into the resin pressure vessel. When

there is no more water flowing in, open a cold water tap so that the excess air will purge out of the system. Once the air is removed, close the tap.

7. You can now switch on the valve electrical power.8. Press and hold the key “ ” for 3 seconds to initiate a manual regeneration. It will last between 30 minutes and 1

hour.Mains Out

SpectrumTM

Once the softener has been installed and setup by a professional, there are some useful functions to be aware of.

Salt replenishment: when the softener runs out of salt, it will not produce any more soft water. It is therefore impor-tant to keep it topped-up, this is done via the lid of the top of the softener. Salt should always be visible over the line of water in the cabinet but the total volume of salt and water should not exceed the overflow level.

NOTE: ONLY USE GRANULATED OR TABLET SALT DEDICATED TO WATER SOFTENERS

Bypass: The Bypass is a function which makes the water softener offline. This is useful when soft water is not required (e.g. using a hosepipe)

In the service position, the softener will produce soft water.In the Bypass position, the water will not go through the resin tank and remain as hard water.

Blending valve: This can be used optionally when some applications require a certain level of hardness. When the blending valve is closed (Fully turned anticlockwise), you will get 100% soft water. The more you open it (turning clockwise), the harder the water will get. Refer to Section 3 for blending valve position.

Display: In service, the valve will display time of day and the number of days left until the next regeneration.

Regeneration is a standard process required to recharge the resin contained inside the softener. The regeneration will happen at the time set in the program. A motor noise can be heard when the softener is in regeneration mode, this is normal.

The screen will display the various cycles of the regeneration and will then go back to service mode.

• Backwashing• Brining• Rinse• Refill

Power Cuts: In the event of a power cut the Chrono will keep its settings in memory for up to 48 hours. After 48 hours reprogramming may be necessary, please refer to section 5.3 for ‘Valve Set-up’ and ‘Program Settings’.

Downtime: After holidays, or a long period without using water over a week, it is recommended to initiate a manual regeneration in order to flush the resin tank. During this time only hard water will be available. Refer to section 6 for instructions.

10. 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 filter 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 qualified 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 firstly be discharged from inside the water softener.
