C)Reverse osmosis system pic. 3,4
When the water has a chloride concentration Cl- above
150 mg/l (= ppm) (information available from the water
company), a reverse osmosis system must be installed to
avoid corrosion. Note that the water has a minimum
conductivity of 50 µS/cm.
D) Water softener: pic. 3,4
A water softener is recommended when a high level of
scale (not containing chloride) is experienced. Systems
recommended: H+ Ion Exchanger or Kleensteam. Sodium
ion exchangers (as used in dishwashers) must not be used
because of sodium deposits and delays in boiling caused
by a high salt content.
Filter systems (A,B,C,D) from the following manufacturers are
recommended:
Schuhmacher, Grünbeck, Culligan, Cuno, Everpure, Britta
Christ, Seral.
When selecting a filter, bear the following flow rates
in mind:
Average soft water consumption for steam generator/
humidifying (excluding handshower)
6x1/1GN 10x1/1GN 10x2/1GN 20x1/1GN 20x2/1GN
3,0 l/h 6,3 l/h 10,4 l/h 12,5 l/h 15,0 l/h
Maximum flow rate (necessary for selecting the right size of
filter connection)
6x1/1GN 10x1/1GN 10x2/1GN 20x1/1GN 20x2/1GN
10 l/min 10 l/min 10 l/min 10 l/min 10 l/min
Total average water consumption for steam generator,
humidifying and quenching (excluding handshower)
6x1/1GN 10x1/1GN 10x2/1GN 20x1/1GN 20x2/1GN
12.0 l/h 25.2 l/h 41.4 l/h 49.8 l/h 60.0 l/h
Maximum flow rate (necessary for selecting the right size of
filter connection)
6x1/1GN 10x1/1GN 10x2/1GN 20x1/1GN 20x2/1GN
20 l/min 20 l/min 25 l/min 25 l/min 25 l/min
The recommendations are constantly updated on the basis of
test results. Addresses are available from the after-sales servi-
ce department.

Ventilation:
An exhaust fan is not essential. If one is fitted, bear the
following points in mind:
• Comply with all local regulations and standards;
• The fan should project 300-500 mm in front of the
appliance;
• Install a grease filter in the projecting part of the fan;
• An exhaust fan is available as an option for 6x1/1 GN and
10x1/1 GN units. This can also be retrofitted;
