water, cooling water and air conditioning water and for reducing malfunctions

and damage due to lime in water pipes and connected water-carrying system

components.

4 Function4 Function

4 Function

Rondomat Duo is a duplex softening unit which functions in accordance with

the ion exchange principle. The unit is run with columns continually changed

at short intervals. This method of operating ensures that softened water is

even available during a regeneration procedure, while the frequent column

change minimises stagnation times. In terms of chemical and microbiological

parameters, this leads to significantly better water quality than with

conventional alternating softening units.

Regeneration is triggered volumetrically (depends on the quantity of water).

Very brief salt dilution times and short regeneration periods are achieved as

a result of a salt hopper for storing and dissolving salt and a new quick-filling

system for the brine container (patent pending).

The hardness of local untreated water is entered into the electronic system

when the unit is started. All other unit parameters are stored in the electronic

system. All unit data is preset and unit parameters can be queried. The

remaining capacity is displayed in liters or in bar-graph form.The flow quantity

is displayed in l/h during operation.

5 Installation Conditions5 Installation Conditions

5 Installation Conditions

Observe all applicable installation regulations, general guidelines, hygiene

requirements and technical specifications.

Water softeners may not be installed in water supply systems that provide

water for fire extinguishing purposes.

The pipeline network must be flushed before the unit can be installed.

The hard water to be fed into the unit must always meet the specifications

of the German Drinking Water Ordinance [“Trinkwasserverordnung”]

or EU Directive 98/83/EC. The total dissolved iron and manganese may

not exceed 0.1 mg/l. The hard water to be fed into the unit must always be

free of air bubbles. Install a bleed device if necessary.

Continuous operation of the water softener with water containing chlorine

or chlorine dioxide is possible if the concentration of free chlorine/ chlorine

dioxide does not exceed 0.5 mg/l.

However, continuous operation with water containing chlorine/chlorine

dioxide causes the ion exchange resin to age prematurely. A water sof-

tener reduces the concentration of free chlorine and chlorine dioxide. In

other words, the concentration in the outflow of a water softener is gen-

erally considerably lower than in the inflow.

The unit should be sized in such a way that regeneration is necessary at

least once a day based upon the throughput. If water consumption is

reduced, e.g. during holidays, a shut-off device must be fully opened for

at least 5 minutes before water can be used again.

Use corrosion-resistant pipe materials for installation. Pay attention to

corrosion-causing chemical properties when different pipe materials are

combined (mixed installation), even in the direction of flow upstream of

the softening unit.

A protective filter must be installed in the direction of flow no further than

1 m1 m

1 m upstream from the softening unit. The filter must be functional before

the softening unit is installed. This is the only way to ensure that dirt and

corrosive products do not enter the water softener.

You must check whether a mineral substance metering device needs to be

installed downstream from the water softener for the purpose of preventing

corrosion.

When installing the water softener, select a location where the unit can easily

be connected to the water supply network. A connection to the sewage

system (at least DN 50), a floor drain and a separate power supply (230 V

/ 50 Hz) must be located in the immediate vicinity.

The emission of interference (voltage peaks, high-frequency electromagnetic

fields, interference voltages, voltage fluctuations, etc.) by the surrounding

electrical systems may not exceed the maximum values specified in EN

61000-6-4.

The rated mains power (230 V / 50 Hz) and the required operating pressure

must be present at all times. A separate means of protection against a

shortage of water is not provided and must be installed on site if desired.

If no floor drain and/or structural waterproofing compliant with DIN 18195-5

is present, a separate safety device (e.g. a hydrostop) must be used.

The installation site must be protected against frost and provide protection

against chemicals, paints, solvents, fumes and excessive ambient tem-

peratures.

If the softened water is intended for human consumption as defined in the

German Drinking Water Ordinance [“Trinkwasserverordnung”], the ambi-

ent temperature must not exceed 25°C.

The hose attached to the overflow of the brine container and the flushing

water hose must be routed at an incline to the sewage system or connected

to a pump. Note:Note:

Note:Note:

Note: In accordance with DIN EN 1717, the flushing water and

overflow hoses must be connected at least 20 mm above the highest possible

waste water level (unimpeded drainage).

If flushing water is fed into a pump, it must be designed for a water volume of

at least 2 m3/h or 35 l/min. If the pump is used for other units concurrently, it

must be of a larger size to suit the units’ water output volumes.

The pump must be salt-water resistant.

nerative to a filling height of 250–350 mm (see Technical specifications). The

brine cavity automatically fills with water during the “disinfection” stage. Wait

and then check that the automatic water refilling turns off as soon as the

water has risen above the sieve base. Pour in the regenerative (always

adding whole units) up to a maximum of 75–150 kg. Close the cover and lock

it.

Calculating the sodium content of partially softened waterCalculating the sodium content of partially softened water

Calculating the sodium content of partially softened water

The sodium content increases by 8.2 mg/l if the hardness of untreated water

is decreased by 1 °d.

Hardness of untreated water – hardness of blended water x 8.2 mg/l =

increase in the sodium content.

Ask at the water works what the sodium content of untreated water is (e.g.

10 mg/l).

Sodium content of untreated water + increase of sodium content (due to

softening) = sodium content of partially softened water.

Repeated dosage further increases the sodium content by approx. 5 mg/l.

Drinking water regulations stipulate a sodium limit of 200 mg/l. We recommend

setting the treated water to a hardness between 4 °d and 8 °d. If the mandatory

sodium limit of 200 mg/l is exceeded, the blended water hardness may have

to be set at more than 8 °d.

The unit is now ready for use.

Power failure

If there is an extended power failure (8 hours), the unit starts operation with

a regeneration when the power returns.

If the power failure occurred during a regeneration, the controller regener-

ates the column in which the regeneration process was interrupted when

power returns.

Shutting downShutting down

Shutting down

BWT drinking water softening units are produced and supplied hygienically.

After start-up the ion exchanger resin tends to become infected if shut down

incorrectly and therefore to release organic substances.

Therefore, the procedure described below is required under the following

conditions:

If no water is available for more than 48 h (e.g. for modifications, the softe-

ning unit is disconnected from the drinking water network).

If the softening unit is not required for an extended period (more than

4 weeks, e.g. seasonal operation in a hotel).

Ideally, the softened water supply should be almost completely used up

before shutting the unit down.

The columns should only being flushed and not regenerated.

If this is not possible, the unit should be regenerated completely.

The water supply to the unit can now be shut off and the unit can be

disconnected from the power supply.

Reactivating the unitReactivating the unit

The unit must be completely regenerated anyway (both columns for

We recommend hygienic maintenance by our after-sales service team after

the unit is shut down.
