Water hardness Scale deposits may form if the total water hardness or carbonate hardness exceeds 5 °dH (0.89 mmol/l). For values smaller than this, the scale formation is correspondingly less. A total water hardness or carbonate
hardness of 1 °dH is ideal. Certain water components (Na+ ions and silicates) can cause the windows to become cloudy. This effect depends on the quality of the water and how the unit is used. Decarbonisation or full desalination systems can prevent the formation of scale deposits.
A water softening system should be installed upstream if the water is very hard.
Water softening systems based on electromagnetic fields do not provide protection against scale deposits with combisteamers.
Pipes from galvanized steel or other corrosive material may not be used downstream from water softening systems.
Systems with phosphate and silicate dosing may not be used. Deposits may form in the cooking chamber with such systems.
Units in the SpaceSaver and SpaceSaver PLUS versions can display the maintenance intervals of a connected water softening system on the
5.1.2Information about the hard water supply
Cooling waste steam Cold water that has not been softened can be used for cooling waste steam.
Warm water leads to increased water consumption and should not be used.
The water temperature must not exceed 50 °C (122 °F).
Automatic cleaning system Units that are equipped with the “WaveClean” automatic cleaning system “WaveClean” must always be connected to a hard water and a soft water supply.
Otherwise, cleaning with “WaveClean” is not possible.
