and operated. The most important factors are listed in the following table.
Unfavourable conditions
BWT recommendations

water
Unsuitable and marginal quality
inflow water may not be altered by
the product

Operating conditions
Long periods of stagnation, infre-
quent regeneration and incorrect
configuration of the system can
adversely affect the quality of the
pearl water
Observe the notes in the installation
and operating manual, contact the
BWT drinking water specialist or fitter
Quality of the regen-
erative
Impurities from cheaper regener-
atives with insoluble components
cause deposits
Use of BWT Perla tabs or regeneratives
that comply with DIN EN 973 type A
Installation situation and
conditions
Temperatures in the installation
room greater than 25°C, evapo-
ration of solvents or an improper
waste water connection may ad-
versely affect the quality of the
pearl water
Observe the notes in the installation
and operating manual
When determining whether there is a problem with the sensory or microbiological quality of the treated
water, it is important where in the system the quality is measured. For example, if the quality is measured
at the tap, the water quality may be affected by the pipe material or by the presence of a water heater
or hot water storage tank.
