4.2.1
Water treatment systems
D
The manufacturers of water softening devices offer systems provided specifically for hot circulating-air
steamers/combi-steamers. They may also be combined with particle-/fine- and active carbon filters. We
recommend, for example, the water softener from Brita Co.
D
Do not connect the water softener to previously softened water.
D
Reverse- or osmosis-systems may generally constitute an economic alternative to full and/or partial
desalination via filtering systems. Osmosis systems remove nearly all hardness-forming ingredients
and non-hardened minerals from the water. These systems are also required to remove high chloride-
and silicate concentrations.
D
Particle-/fine filters with filter grades 5-15
µ
m filter, for example, contaminations such as deposits from
water pipes, sand, iron particles or suspended matter. Choose sufficient flow capacity of the fine filter to
prevent any pressure loss and to ensure an adequate flow rate.
D
Active carbon filters remove excessive chlorine contents.
4.2.2
Do not use these systems.
D
Sodium ion exchangers (as customary with dish washers) are not permitted for these appliances.
Glazing may become dull and irreparable damage may occur in the cooking chamber.
D
Systems with phosphate- and silicate dosing may not be used. They may cause malfunctions in appli
ance parts and deposits in the cooking chamber.
D
Systems based on electromagnetic fields do not provide protection against scale formation with this
type of appliance.
