Check the chloride concentration (Cl
-
), chlorination (Cl
2
), conductivity and
water hardness with your local water supplier.
n
When connecting the iCombi Pro to water with less than 7 °dH: When the
self test is started, a query is made as to which water hardness the device is
connected to. In this case, select the point water hardness below 7 °dH.
n
A water connection without additional filters and water treatment is possi-
ble in most cases.
n
If critical water conditions prevail, filtration and/or water treatment is nec-
essary.
8.4 Selection of the water filter
If critical water conditions prevail, filtration and/or water treatment is neces-
sary. Observe the following notes when making your selection:
(A) Fine filter
If the water is contaminated by sand, iron particles or suspended particles, we
recommend fine particle filters with 5 – 15 µm [0.0002 – 0.0006 inch] filter
size.
(B) Activated carbon filter
In the case of strong chlorination (Cl
2
) of the water above 0.2 mg/l (corresponds
to 0.2 ppm), an activated carbon filter must be installed upstream. Information
on the chlorination (Cl
2
) can be obtained from the local water supply company.
(C) Reverse osmosis system
If the chloride concentration (Cl
-
) is above 80 mg/l [80 ppm], a reverse osmosis
system must be installed due to the risk of corrosion. Information about the
chloride concentration (Cl
-
) can be obtained from the local water supply com-
pany.
NOTE
Malfunction due to falling below the minimum conductivity value
Make sure that the minimum conductivity of the water is 50 μS/cm [32 ppm
TDS].
(D) Water softening
iCombi Pro / iCombi Classic
When used according to instructions, iCombi Pro / iCombi Classic devices re-
move the limescale themselves. Upstream water softening for scale is not nec-
essary.

Water softening is recommended for water treatment in the event of very
strong calcification (without chloride contamination).
