Operator Responsibilities
You have purchased a product that is durable and
easy to service. However, all technical equipment
requires regular servicing in order to guarantee
optimal functionality.
German drinking water ordinance requires you to log
the amount of regenerative consumption.
However, this does not apply to BWT’s AQA perla
series water softeners, which record the measured
values. Keep yourself up to date with regard to the
quality and pressure ratio of the water which is to
be treated. If the water quality changes, the settings
may need to be changed. Consult a specialist in
this case.
To ensure proper functioning and to meet the war-
ranty requirements, regular inspections must be
carried out by the operator (every 2 months), and
routine maintenance (EN 806-5) must be performed
by the BWT after-sales service staff or an installer
authorised by BWT to carry out maintenance (every
6 months).
Wearing parts must also be replaced within the
prescribed maintenance intervals in order to ensure
functionality and fulfil the warranty conditions.
9.1
Inspection
The operator must regularly perform the following
inspections.
Regenerative
According to use
Check and refill
Test water hardness
Once a month
The hardness of the local drinking water and the
set hardness of the outlet water must be checked
and corrected if necessary (see Start-up section).
Visual inspection
Every 2 months
Check connection lines and connections for leaks.
Check for dirt in the regenerative container and
clean and flush with clear water if necessary.
Cleaning
At least once a year
Sanitize the regenerative container
Disinfection
In unfavourable conditions, e.g. if the unit is located
in a warm room and has not been used for a long
time, it may require disinfection by our after-sales
service staff in addition to regeneration.
Additional disinfection is not required if regene
-
rations are performed regularly (by the quantity
controller or time override controller).
The intervals between checks are recommended
minimums and must be reduced accordingly for
sensitive consumer systems.
9.2
Maintenance
The BWT after-sales service staff or an installer
authorised by BWT must carry out the following
maintenance work regularly.
We recommend that you enter into a maintenance
agreement with your installer or the after-sales
service team.
Functional tests
Brine extraction system
Twice a year
Water meter
Twice a year
Drive motor(s)
Twice a year
Hydraulics test
Twice a year
Sanitization of the regenerati-
ve container
Twice a year
Replacement
Single valve with exchanger
columns

years
10 Warranty
If the product malfunctions during the warranty
period, please contact your contract partner, the
installation company, and quote the unit type and
production number (see Technical specifications or
the type plate on the unit).
Non-compliance with the installation conditions and
the operator responsibilities voids the warranty.
The wearing parts defined in the “Operator
Responsibilities” section and the cosequences of
failing to replace these parts on time are not covered
by the 2-year legal warranty.
BWT assumes no liability in the event that the unit
fails or if the capacity becomes deficient due to
incorrect material selection/combination, floating
corrosion products or iron and manganese deposits,
or any resulting damage thereof.
The use of regenerative that does not comply with
DIN EN 973 type A voids the warranty.
