(B) Activated carbon filter
In the case of strong chlorination (Cl
sponds to 0.2 ppm), an activated carbon filter must be installed upstream. In-

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 units re-
move the limescale themselves. Upstream water softening for scale is not nec-
essary.

Notes on connecting the water filter
The diameter of the water hose must be at least 1/2 inch ID, to the water filter
at least 3/4 inch ID.
When using a combination of water filters, observe the order of the filters in
