Each species of plant and aquatic animal requires

water that contains a special combination of sub-

stances. Users of the unit should therefore con-

sult the standard literature and check that they

can use retreated drinking water for watering plants

or for filling ornamental lakes, aquariums or fish-

ponds.

Intended Use

AQA Perla is intended for the softening or partial

softening of drinking and service water (according

to relevant standards and rulings, DIN 1988, part

2 and 7 and regulations of the DVGW [German

association of gas and water specialists]). It is also

designed to prevent calcification damage to water

pipes, fittings, boilers and other equipment and to

prevent malfunctioning.

FunctionFunction

Function

AQA Perla is a duplex softening unit that functions

in accordance with the ion exchange principle. The

unit is run with columns continually changing at

short intervals. This method of operating ensures

that softened water is even available during a re-

generation 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 con-

ventional alternating softening units.

Regeneration is triggered volumetrically (depends

on the quantity of water).

Very brief salt dilution times and short regenera-

tion periods are achieved thanks to the special

salt hopper for storing and dissolving salt.

The hardness of the drinking water and the de-

sired hardness of blended water on-site is entered

into the electronic system when the unit is started-

up. All other unit parameters are stored in the elec-

tronic system. All unit data is preset and unit pa-

rameters can be queried. The remaining capacity

is displayed in litres or in bar-graph form. The flow

quantity is displayed in l/h during operation.

The unit is equipped with a device that disinfects

the ion exchanger during the regeneration proc-

ess. Spring-loaded non-return valves protect all

water connections on the inlet side of the unit (in

compliance with DVGW). This eliminates the need

for a system or pipe isolator.

The system complies with all relevant national and

international standards.

Electrical power failureElectrical power failure

Electrical power failure

In case of an electrical power failure of more than

8h the softener restarts with an automatic regen-

eration of both columns.

All settings are permanently stored and do not have

to be reentered after an electrical power failure.

Installation RequirementsInstallation Requirements

Installation Requirements

Observe all applicable installation regulations, general

guidelines, hygiene requirements, and technical speci-

fications.

Softening systems may not be installed in water sup-

ply systems which provide water for fire extinguishing

purposes.

The pipe network must be flushed before the unit is

installed.

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

the specifications of the German drinking water regu-

lations or EU directive 98/83 EC. The total dissolved

iron and manganese may not exceed 0.1mg/l. The

hard water to be fed into the unit must always be free of

air bubbles; if necessary, a bleed device must be in-

stalled.

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 0.5mg/l.

However, continuous operation with water containing

chlorine/chlorine dioxide causes the ion exchanger resin

to age prematurely. A softening unit reduces the con-

centration 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.

The unit should be sized so that at least daily regen-

eration is necessary based on 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 (DIN 1988

sections 4 and 8).

Use corrosion-resistant pipe materials for installation.

Observe corrosion-causing chemical properties in the

combination of different pipe materials (mixed installa-

tion), even in the direction of the flow upstream of the

softening unit.

A protective filter must be installed no further than 1m1m

1m1m

1m

upstream from the unit. The filter must be functional

before the water softening unit is installed. This is the

only way to ensure that dirt and corrosive products

cannot enter the softener.

You must check whether a mineral dosing device should

be installed downstream from the unit for the purpose

of preventing corrosion.

GBGB

When installing the unit, select a location where the unit

can easily be connected to the water supply network.

A connection to the sewage system (at least DN50), a

floor drain and a separate mains socket (230V/50Hz)

must be nearby.

The emission of interference (voltage peaks, high-fre-

quency electromagnetic fields, interference voltages,

voltage fluctuations, etc.) by the surrounding electrical

systems may not exceed the maximum values speci-

fied in EN 61000-6-4.

The rated mains power (230V/50Hz) and the requisite

operating pressure must be present at all times. A

separate means of protection against a lack of water is

not provided and must be installed on-site if required.

If no floor drain and/or structural waterproofing compli-

ant with DIN 18195-5 is present, a separate safety

device (e.g. a hydrostop) must be used.

The installation site must be free of frost and kept free

of chemicals, paint, solvents and fumes, and the ambi-

ent temperature must not be too high.

If the softened water is intended for human consump-

tion as defined in the German drinking water regula-

tions, the ambient temperature must not exceed 25°C.

The hose attached to the overflow of the brine con-

tainer and the flushing water hose must be routed at an

incline to the sewage system or connected to a pump.

Note:Note:

Note: According to DIN 1988, the flushing water hose

must be secured at a distance of at least 20mm from

the highest possible waste water level (free discharge).

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.
