C) Reverse osmosis system Due to corrosion risks, a reverse osmosis system
must be used if and only if chloride (Cl
–
) con-
centrations are above 80mg/l (corresponds to
80ppm, information provided by water supply
company).
Note: Ensure that the minimum conductivity
value of 50µS/cm (Micro Siemens) is being
maintained.
D) Water softening:
SCC: When used properly, these devices remove lime
from water completely independently, so upscale
water softening is not necessary.
CMP/CM: Recommended for treating water if severe cal-
cification occurs (without chloride contamina-
tion). Systems: Weak acid decarbonization (H
+
ion exchange). Sodium ion exchangers (as are
commonly found in dishwashers) are not recom-
mended.
Phosphate metering is also not recommended
due to its negative effects on the water system.
Important for soft water connections:
To increase filter capacity, split the water connec-
tion into cold water and soft water (not possible
with size 60 units) - remove the common water
supply line.
Filter size sufficient for:
Average soft water consumption
(without hose shower) at max. flow rate of 16l/
min.
Appliance size 61 62 11 12 21 22
[l/h] 3.0 8.0 6.3 10.4 12.5 15.0
Important for filter connections: Water hose with minimum ø 1/2”.
Filter connection ø 3/4”.
When using a combination of filters, ensure filter
sequence of A-B-C or A-B-D in direction of flow.
