For all issues about sensory and microbiological quality of the treated water, there is a difference

depending on the location, from which these are being evaluated. In terms of an evaluation at an

extraction point, the pipe material, water heater or hot water storage tank, among other things, could

have a decisive impact on the water quality.

aquatic animals

Each species of plant and aquatic animal requires

water that contains a special combination of sub-

stances. Users of the unit should therefore consult

standard literature and check that they can use

retreated drinking water for watering plants or for

filling ornamental lakes, aquariums or fishponds.

The control unit of your product includes a long-

life battery.

Batteries and power packs must not be disposed

of in the household waste!

You are obligated to take batteries to a suitable

recycling point or return them, free of charge, to

BWT. Old batteries contain valuable resources

that can be reused.

4 Function4 Function

4 Function

The unit operates according to the principle of

intelligent regeneration.

Intelligent quantity-dependent regenerationIntelligent quantity-dependent regeneration

Intelligent quantity-dependent regeneration

When the unit is started, the available supply of

softened water is programmed (depending on the

hardness of the drinking water).

At a user-defined time (e.g. at night), the unit

checks whether the remaining supply of softened

water is sufficient for the following day.

If not, the softening column is regenerated in or-

der to refill the supply of softened water up to

100%.

In the event of a power failure, the data and the

time are kept (about 1 year).

The unit is equipped with a device that disinfects

the ion exchange resin during the regeneration.

Spring-loaded non-return valves protect all water

connections on the inlet side of the unit.

Automatic activation of regenerationAutomatic activation of regeneration

Automatic activation of regeneration

If the capacity is not used up within four days, the

electronic system triggers a regeneration.

The system complies with all relevant national

and international standards.

Only for Bewamat 75 AOnly for Bewamat 75 A

Only for Bewamat 75 A

Two capacity levels can be set on the controller,

making the unit suitable for larger applications.

The unit is preset. In case less performance

is necessary, this can be set by after-sales

service.

5 Installation conditions5 Installation conditions

5 Installation conditions

General informationGeneral information

General information

Observe all applicable installation regulations,

general guidelines, hygiene requirements and

technical specifications.

Site of installation and surrounding area

Water softeners must not be installed in water

supply systems that provide water for fire

extinguishing purposes.

The site of installation must be frost-proof, must

guarantee protection of the unit against

chemicals, dyes, solvents and vapours, must

have construction waterproofing in accordance

with DIN 18195-5 and enable easy connection to

the water supply.

To protect the drinking water installation from

backflow, a type BA system separator must be

installed in front of the water softener in

accordance with DIN EN 1717.

A wastewater connection, a floor drain and a se-

parate network connection (230 V/50 Hz) must

be close by.

The power supply must be permanently

guaranteed.

If the treated water is exclusively for use in

technical applications, the ambient temperature

must not exceed 40°C.

Electromagnetic interference (voltage peaks, high-

frequency electromagnetic fields, interference

voltage, voltage deviations …) by the surrounding

electrical installations must not exceed the

maximum values stated in EN 61000-6-4.

Separate protection against water deficiencies

does not exist and must be fitted locally – if

required.

Feed-in waterFeed-in water

Feed-in water

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. If necessary, an exhauster must

be installed.

2626

26

GBGB

GB

The necessary operating pressure must always

be guaranteed.

A minimum operating pressure is required for the

unit to function (see technical data).

The maximum operating pressure of the unit must

not be exceeded (see technical data). If the

network pressure is higher, then a pressure

reducer must be installed upstream of the unit.

In the case of pressure deviations and pressure

surges, the total of the pressure surge and

standing pressure must not exceed the nominal

pressure, meaning the positive pressure surge

must not exceed 2 bar and the negative pressure

surge must not fall beneath 50% of the adjusted

flow pressure (see DIN 1988-200/3.4.3).

Continuous operation of the softening unit 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 exchanger resin to age prematurely. A softe-

ning unit reduces the concentration of free chlorine

and chlorine dioxide. In other words, the

concentration in the outflow of a softening unit is

generally considerably lower than in the inflow.

InstallationInstallation

Installation

The pipe network must be flushed before the unit

is installed.

Use corrosion-resistant pipe materials for

installation. Observe corrosion-causing chemical

properties in the combination of different pipes

(mixed installation), even in the direction of the

flow upstream of the softening unit.

The hose attached to the overflow of the brine

container and flushing water hose must be routed

at an incline to the sewage system or connected

to a pump.

According to DIN 1717, the flushing water hose

and the overflow hose must be secured at the

specified distance from the highest possible waste

water level to the sewage connection (distance

greater than the diameter of the waste pipe).

If flushing water is fed into a pump, it must be

designed for a water quantity of at least 2m3/h or

35 l/min. If the pump is used for other units

simultaneously, it must be sized larger by a factor

of their water output quantities.

The pump must be salt-water resistant.

Place and align the softening column with control

valve behind the cabinet.

Run the the brine hose from the inside though the

bore to the outside and insert it as far as it will go

(a depth of about 15 mm) in the connection angle.
