Proper use
This product is intended for the partial softening of
drinking and service water. It is also designed to
prevent malfunction and damage caused by calci-
fication in water pipes and the connected fittings,
devices, boilers and other equipment.
The product is installed if the installation system
downstream from the softener contains parts made
of galvanised steel.
The performance specifications of the product must
match the expected usage conditions. For more
information, see DIN 1988-200 and the technical
data in this installation and operating manual (see
chapter
74).
If the product is intended for a commercial appli-
cation, a consultant from the manufacturer must
conduct a test and issue an approval.
Operation of the product only with regular function
checks and the performance of the maintenance
measures required to ensure the safe operating
condition of the product in accordance with the
operating conditions for planning and construction.
The mineral substance metering is used to meter
BWT Smart Mineral.

Function
The BWT Perla hybrid is a simplex water softener
that functions using ion exchange. The product is
filled with organic ion exchange material.

Operation
●
Adaptive sequential operation allows for maxi-
mum soft water availability and minimises stag-
nation in the column.
●
Regeneration is triggered volumetrically (depend-
ing on the quantity of water). This means that no
remaining supply of softened water is discarded
during regeneration.
● During the regeneration process, untreated inflow
water is available.
●
Ideally, the regeneration time occurs at night,
as water consumption is usually lower during
this period.
●
If the capacity falls below 50% before the query
time, proportional regeneration starts immedi-
ately.
●
If the capacity does not fall below 50% until after
the query time, the control system assumes that
the remaining capacity is sufficient to last until
the regeneration time.
●
Regeneration begins immediately if the capacity
is exhausted; otherwise it starts at the selected
regeneration time.
●
The integrated water meter measures the water
volume flowing through and sends pulses to the
electronic controller. The controller controls the
drive motor for the piston metering pump, which
proportionally adds the active substance to the
water flow using the injection point.
●
With the original factory settings, using the min-
eral substance metering device with BWT Smart
Mineral fulfils the requirements of the German
Drinking Water Ordinance. These settings are
chosen to achieve the desired process result.
●
The mineral substance metering device is
equipped with a built-in level monitor that au-
tomatically switches the unit off once the active
dosing substance has been used up in order to
prevent the metering pump from running dry. In
addition, a notification is shown on the display
(see empty notifications).
●
The metering amount is pre-set and does not
require adjustment.
