Installation instructions
4.2.4
Requirements on the soft‐ and cold‐water connection
D
The steam generation in the appliances is carried out as fresh steam, that means, the water is directly
introduced into the cooking chamber.
D
The water must conform to the Drinking Water Regulations.
D
In order to prevent damage to the appliance, the following requirements must be observed.
Soft water
Cold water
Application
For steam generation and automatic
cleaning.
A backflow preventer is installed in
the water supply line.
For the steam relief and pull‐out
shower
A backflow preventer is installed in
the water supply line.
Water temperature
Max. 50
°
C
Cold water (max. 20
°
C)
Do not connect to hot water due to
excessive water consumption or poor
function of the steam relief (steam
condensation)!
Min. water
pressure
200 kPa = 2 bar (dynamic / flow pressure)
A booster pump must be installed if the water pressure is too low. Check the dy
namic water pressure, e.g. with the pull‐out shower opened.
Max. water
pressure
600 kPa = 6 bar (static)
A pressure reducer must be installed if the water pressure is too high.

Install a reverse osmosis system
above 10 mg/l; otherwise there is a
risk of damage from glazing corro
sion.
Chlorine /Chlorine
dioxide content
At a chlorine content above 0.1 mg/l (corresponds to 0.1 ppm) an active carbon
filter needs to be installed.
Chloride
Max. 50 mg/l (50 ppm)
Above 50 mg/l (50 ppm) a reverse osmosis system needs to be installed;
otherwise strongly increased risk of corrosion.
Iron
Max. 0.1 mg
pH value
6.5 - 7.5

Contaminations
Install a water filter grade 5‐15
µ
m to remove, e.g. water pipe deposits, sand, iron
particles or suspended matter.
