a Conductivity: min. 50 µS
a The chlorination (Cl
2
) is below 0.2 mg/l (0.2 ppm) and the chloride concen-
tration (Cl
-
) below 80 mg/l (80 ppm). If the values are higher, use a water
filter. Follow the instructions for selecting the water filter.
1. Connect the water hose to the water inlet for the unit.
2. Open the tap.
>> The water inlet is connected.
Recommendation for CombiMaster Plus without care
The manufacturer recommends a preventive check approx. 6 months after com-
missioning to determine the current limescale build-up in the steam generator.
The inspection should be carried out by a trained technician.
8.3 Notes on water treatment
If the water quality is not suitable for the unit, water treatment is required. Ob-
serve the following notes:
n
Treated water with a hardness of less than 5°dH can have an aggressive and
corrosive effect and shorten the service life of the unit. Do not use treated
water with a hardness of less than 5°dH.
n
Observe the country-specific regulations regarding water and wastewater
connections, in particular also regarding the installation of water extraction
points.
n
Check the chloride concentration (Cl
-
), chlorination (Cl
2
), conductivity and
water hardness with your local water supplier.
n
If the iCombi Pro is connected to water with less than 7°dH: When the self-
test is started, a query is made as to which water hardness the unit is con-
nected 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.
