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
Multi-function display. You will find further information in the operating
instructions.
5.1.2
Information 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
“WaveClean”
Units that are equipped with the “WaveClean” automatic cleaning system
must always be connected to a hard water and a soft water supply.
Otherwise, cleaning with “WaveClean” is not possible.
5.1.3
Fitting the T-piece (accessory)
Hard and soft water connections can be made via a hose with a T-piece
(accessory) in the event that only soft water is available on site.
