1 | Laws, directives, standards

In the interest of good health, rules cannot be ignored when it comes to the processing of drinking water (raw water). This operation manual takes the applicable German guidelines into account and provides all the information you need to safely operate your water treatment system.

Among other things, the regulations stipulate that

 only approved companies are permitted to make major modifications to water treatment facilities,

 and that at regular intervals tests, inspections and maintenance are to be performed on the devices installed.

2 | Water, scaling, softening

The waterworks provide us with pure drinking water (raw water) which is suitable for human consumption. However, in case of the more frequent use of the water in washing machines, heating systems, water heaters, industrial systems, etc., problems might occur if “hard” water is present.

Hard water is generated if water containing carbon dioxide* flows through layers of calcium. It dissolves the calcium until the so-called calcium/carbon dioxide equilibrium has been reached.

If this equilibrium is destroyed (e.g. by heating

CO

2

escapes) more calcium (CaCO

3

) is precipitated (scale).

Water Softener

Weichwassermeister ® GSX 5, GSX 10, GSX 10-I

The total hardness of the water is the sum of the concentrations of calcium ions and magnesium ions.

 Note: In nature, calcium and magnesium ions exist side by side, e. g. in the mineral dolomite.

Hardness ranges according to German Detergent and Cleaning Agents

Act (WMRG):

Hardness range

1 (soft)

°dH °f mmol/l = mol/m 3

0 – 1.5 0 – 8.4 < 15,0

2 (medium) 8.4 – 14 15,0 - 25,0 1.5 – 2.5

>14 > 25,0 >2.5

Starting from hardness range “hard”, it is advisable to soften the water for usage. Additional measures may be necessary depending on the original quality of the water and its intended use.

* CO

2

from the air dissolves in water, causing a low concentration of carbon dioxide.

Water Softener

Weichwassermeister ® GSX 5, GSX 10, GSX 10-I

The exchange of calcium and magnesium ions for sodium ions causes the water to become soft.

Principle

The hard raw water flows through an exchanger tank. This tank is filled with a resin to which sodium ions are bonded at certain positions (refer to fig. B-1).

Since these bonding positions at the resin prefer calcium and magnesium ions to sodium ions, such ions are retained while the resin discharges sodium ions into the water (exchange reaction). This way, all substances causing hardness remain in the exchanger tank. Soft water, loaded with sodium ions, leaves the exchanger tank (fig. B-2). This process continues until the sodium ions are used up.

The exchange reaction can be reversed if a large amount of sodium ions

(salt solution = brine) is added (fig. B-3). By their sheer number, they replace the calcium and magnesium ions at the docking positions of the resin.

This process restores the initial state. The ion exchanger is regenerated and is again ready for softening.

Drinking water (raw water)

For reasons of corrosion protection, a water hardness of at least 3 °dH

(5,3 °f, 0,53 mmol/l is recommendable. According to the German Drinking

Water Ordinance, the limit value for sodium ions (200 mg/l) must not be exceeded. This is achieved by adding untreated drinking water (raw water), a process which is also called “blending”.

3 | Technical specifications

The water softener Weichwassermeister ® GSX is a twin system for a continuous soft water supply. It is equipped with a central control valve for both exchangers and features volume control. The regeneration is released when the pre-set water volume in an exchanger tank has been softened. If the pre-set amount of water between two regenerations is not consumed within 4 days after the last regeneration, the system starts a forced regeneration (as per DIN

19636-100). Raw water is used to regenerate the system.

All system data is shown in table C-1. The information applies to the standard version of the system. Different data for special versions will be provided separately, if applicable.

Warning! Extended periods of standstill may cause bacterial growth in the drinking water. The automatic regeneration counteracts this effect. Therefore, do not disconnect the system from water and power supply when you are absent for longer periods of time.

Attention! Electrically operated valves. In case of power failure during regeneration, water may flow into the drain or brine tank. Check the system and shut off the water supply (if necessary) in case of power failures.

4 | Designated application

Water softeners of the series Weichwassermeister ® GSX are designed for the softening and partial softening of cold drinking and industrial water. As twin systems, they are suitable for a continuous soft water supply.

The water to be softened must be free of iron and manganese (less than

0.2 mg iron and 0.05 mg manganese per litre). Based on the VDI 6023:If the softened water is intended for human consumption in the sense of the

German Drinking Water Ordinance, the ambient temperature must not exceed 25 °C. For exclusively industrial applications, the ambient temperature must not exceed 40 °C. For the softening of drinking water, the stipulations of the German Drinking Water Ordinance are compulsory (max. sodium concentration 200 mg/l (Refer to chapter E, paragraph 3).

The water softener is adapted to the soft water requirements to be expected at the installation site. It is not suitable for considerably differing performances. The nominal flow must not be exceeded.

In case of critical applications (e. g. boiler feed water), we recommend installing a hardness monitoring device (e.g. GENO ® -control SP, order number 172 400).

The system may only be operated if all components are properly installed.

Safety devices must NEVER be removed, bridged or tampered with.

Appropriate application of the system also implies that the information contained in this operation manual and all safety guidelines applying at the installation site be observed. Finally, the system must be maintained and inspected at the specified intervals.

Note: For the production of fully demineralised water (e. g. pre-treatment for reverse osmosis systems), the Weichwassermeister ® GSX 10-I has to be used. A nominal flow which is defined at 750 l/h in combination with a higher salt requirement for the regeneration guarantee a hardness of < 0.1 °dH (0,2 °f, 0,02 mmol/l) throughout the entire filter process.

Note: With regard to the installation of water softeners with optional accessories (refer to chapter C, 6.2), the operation manuals enclosed with these accessories must be observed as well.

1.1 Water installation Certain binding rules must definitely be observed when installing the water softener Weichwassermeister ® GSX. Additional recommendations facilitate the work with the water softener. The installation instructions described herein are summarised in Fig. D-1.

Binding rules

The installation of a water softener represents a major interference with the drinking water system. Only authorised experts may install such systems.

Observe the local installation guidelines and the general guidelines.

Downstream of the Weichwassermeister ® GSX, a water tap has to be provided close by others on site for the purpose of checking the soft water quality.

The water softener must be preceded by a drinking water filter (e. g.

BOXER ® KD incl. pressure reducer) and if necessary, by a pressure reducer. Recommended pressure: 4 bar.

If the process (e. g. reverse osmosis system) established downstream requires such, a system separator has to be installed.

Use corrosion-resistant material for the soft water pipe (e. g. stainless steel, plastic, PE-X). In case of galvanised steel or copper, we recommend dosing a corrosion inhibitor (refer to optional accessories: EXA-

DOS ® dosing computer)

Note: If required, the drain connection can be made at up to 1 m above the water softener. However, in case of a high drain connection, the connection of the overflow hose of the brine tank cannot be made (but this safety feature is not necessarily required as a float valve is installed in the brine tank as an initial safety measure).

Note: Excerpt from DIN 1988 part 7 (4.2.2)

“… Comment: In general the corrosion behaviour of copper pipes, galvanised steel pipes and stainless steel pipes is not influenced by the softening process. However, when switching to softened water in galvanised steel pipes, the water may turn brownish, or in copper pipes it may become greenish. A dosing unit … can counteract this effect.”

Water Softener

Weichwassermeister ® GSX 5, GSX 10, GSX 10-I

Provide a drain connection (at least DN 50) to discharge the regeneration water.

The installation site must have a floor drain. If this is not the case, an appropriate water stop device must be installed (refer to chapter C, paragraph 6.2).

Note: If the regeneration water is directed into a lifting device, this device must be salt water resistant.

Attention! A non-return valve is installed on the inlet side of the connection block (fig. C-2, item 5). Pressure relief safety valves therefore must be installed downstream of the connection block.

1.2 Electrical installation

An earthed socket is required for the electrical connection. It must correspond to the specifications in table C-1 and must be no further from the water softener than 1.20 m.

Attention!

The socket must carry constant voltage (do not couple with light switch or emergency switch of heating system).

2 | Preliminary work

1.

Unpack all components of the water softener.

2.

Check for completeness and soundness.

3.

Place the system at the designated location.

3 | How to connect the system

3.1 Water connection Install connection block into the piping (pay attention to sieve insert)

Mount connection hoses (observe flow direction).

Warning!

Risk of bacterial growth due to stagnation! Acc. to VDI 6023 it is not admissible to fill in drinking water prior to the start of the designated operation.

Therefore, the water softener may only be connected to the drinking water supply immediately prior to start-up.

Make the waste water connection according to DIN EN 1717. In order to do so, shorten the rinsing water hose to the required length and direct it to the drain.

Make sure there is a free outlet (min. 20 mm) to the drain. Fasten the hose with appropriate means in order to prevent the hose from wagging (emerging regeneration water is under pressure).

1717 for small water softeners (order no. 187 840)

Attention!

Risk of damage and malfunctions due to back pressure of waste water. Do not bend the hose.

Shorten the overflow hose of the brine tank to the required length, route it descending to the drain and fasten it according to DIN EN 1717.

3 | How to set the soft water hardness (only GSX 5, GSX 10)

Note : When setting the soft water hardness, a tap should be completely open (e. g. open tap at the sink).

Set the blending valve to a medium value at the scale. The figures at the blending valve are only markers and do not indicate the soft water hardness.

Withdraw a water sample at the closest tap and determine the soft water hardness.

Soft water hardness too low:

Turn the blending valve a little further to the left (open).

Soft water hardness too high:

Turn the blending valve a little further to the right (close).

Repeat this process until the desired soft water hardness is achieved.

Hold the blending valve and slightly tighten the locking screw.

Note : We recommend storing the operation manual close to the system by inserting it in the transparent envelope and fastening it at the pipes with two cable clips after the start-up process is completed.

Note: When softening drinking water, the stipulations of the German

Drinking Water Ordinance are compulsory! Max. sodium concentration:

200 mg/l.

Sodium concentration

Your local waterworks will inform you about the sodium concentration of the raw water. When softening the water by 1 °dH (1,8 °f, 0,18 mmol/l), the sodium concentration increases by approx. 8.2 mg/l. If the requirements of the German Drinking Water Ordinance must be observed, the water cannot be softened indefinitely. The permissible blending hardness results from the limit value for the sodium concentration and the raw water hardness.

200 y mg/l (limit value acc. to Ger. Drinking Water Regulations)

– x mg/l (sodium concentration in raw water) mg/l (permissible dosing of sodium during softening) y

= Z °dH (max. possible softening)

The raw water may be softened by up to a maximum of Z °dH. Depending on the sodium concentration of the raw water, a blending hardness must be chosen which is lower than the maximum value of 200 mg/l.

Example for the softening of drinking water

Raw water (28 °dH, 50 °f, 5,0 mmol/l) contains sodium (10.5 mg/l).

Permissible dosing of sodium during softening:

200 mg/l – 10,5 mg/l = 189,5 mg/l

This means that the maximum permissible softening is:

 dH (41

 f, 4,1 mmol/l)

28 – 23 = 5°dH (9 °f, 0,9 mmol/l)

1 | Basic information

In order to guarantee the reliable function of the water softeners over a long period of time, some maintenance has to be performed at regular intervals. In particular when it comes to softening within the range of the drinking water supply, the required measures to be taken are stipulated in standards and guidelines. Furthermore, all regulations and guidelines which apply at the installation site must be observed.

DIN 1988 part 8/A 12 stipulates:

Inspection every second months.

Yearly maintenance.

For documentation of the maintenance work, an operation log (refer to chapter H, paragraph 4) must be kept.

Note: By concluding a maintenance contract, you ensure that all required maintenance work will be performed in due time.

Warning!

Impurities introduced to the brine tank may adversely affect the water quality.

Therefore, be very careful with regard to hygiene when refilling salt.

Attention!

Insoluble impurities in the salt may cause malfunctions at the brine valve and at the injector of the control valve.

Only use salt tablets as per EN 973 type A.

Attention! If the minimum salt filling level is undershot, hardness will break through. Regard minimum salt filling level (refer to marking line at brine funnel).

According to DIN 1988 part 8 / A 12, maintenance work on water softeners may only be performed by the manufacturer’s technical customer service or an authorised and specialised company.

2 | Inspection (functional check)

You may perform the regular inspections yourself.

Determine the raw and soft water hardness

(water test kit „total hardness“).

Check the settings at the control unit: a) Time b) Raw water hardness

Check the salt level in the brine tank, respect the minimum salt filling level (refer to marking line at brine tank funnel). If necessary, refill salt tablets.

Check salt quality – salt must not be clumped together. If necessary, remedy clumping by means of an appropriate tool.

Fig. H-1: Determine the hardness

Fig. H-2: Marking line at brine tank funnel

 Evaluate the salt consumption subject to the water volume consumed.

Note: Minor deviations are normal and cannot be prevented technically.

If you detect major deviations, please contact the technical customer service.

 Check tightness of control valve towards the drain (in operating mode without regeneration process).

3 | Maintenance

Read water pressure, flow pressure and water meter reading.

Determine hardness: raw water hardness, soft water hardness, 0 °dH (0 °f, 0 mmol/l) test.

If necessary, readjust blending valve and check soft water hardness again.

Adjust the electronics settings subject to the measured hardness values.

Check the programming at the control unit.

Check brine control (salting, filling of brine tank).

Check release of regeneration.

Check start of turbine water meter.

Check control valve for proper functioning and tightness, replace wearing seals, if necessary; lubricate the pair of disks with grease, if necessary; check function of drive motors of control valve, clean injector and sieve.

Clean brine tank and brine valve.

Check regeneration salt supply (volume and quality – no clumping).

Check hose connections and seals and replace, if necessary.

Attention: Danger of water damage! Damaged or worn hose connections may tear.

Therefore, DIN 1988, part 8 and paragraph A 12 recommends to replace the flexible connection hoses after two years.

 Functional check of the disinfection unit.

 If necessary, read regeneration counter, total quantity of soft water, error memory.

 If necessary, reset maintenance interval.

 Enter all data and work performed, including repair work, in the operation log.

 Turn the system and the filled-in operation log over to the operator.

Warning!

Risk of infection due to germ-infested drinking water. In stagnating water, the amount of germs may increase to an unacceptable level. Therefore, pay particular attention to hygiene when working on water softeners and disinfect the system, if necessary.
