The wave movement causes only water molecules
to adhere to the 'evaporator fingers', while minerals
(e.g. lime) and contaminants remain in the water
residue. This ensures that the ice cubes are clear,
even at higher degree water of hardness.
The ice thickness motor continuously measures the
ice thickness. Once the factory-set ice cube size is
reached, the ice-making process is terminated
(please see chapter 6.2 regarding the size of the ice
cubes).
The unused water is fed into the drain via a
separate channel by tilting the trough. This ensures
that contact with the ice cubes already produced is
avoided, so that the cubes remain hygienically
clean.
The automatically initiated defrosting phase causes
the ice cubes to be separated from the evaporator,
so that they fall into the storage container. Once all
ice cubes have been separated, the trough returns
to its original position below the 'evaporator fingers'.
A new ice-making process commences. This procedure is repeated until the storage container is full.
Once the storage container is full, the device switches off automatically. It automatically switches back on again
once a sufficient number of ice cubes has been removed from the storage container.
NOTE:
In case of longer production breaks (e.g. Holidays), it is recommended that you switch off (Position
“Produktion aus/off”) the machine (see chapter 5.7) for hygienic reasons (automatic emptying of residual
humidity of the production trough) and for cost saving reasons (water and electricity).
6.2 Height and thickness of the ice cubes
The height and thickness of the ice cubes produced depends on the
water level in the trough and on the ice thickness motor setting. The
water level is controlled electronically via the water level sensor.
The ice thickness motor checks the ice thickness once every minute.
Once the set ice thickness has been reached, the ice thickness motors
triggers the ice thickness limit switch, thus initiating the defrosting phase.
The height and thickness of the ice cubes can be modified by adjusting
the water level sensor and the ice thickness limit switch (see chapter 6.3
and 6.4).
CAUTION:
The setting of the ice thickness limit switch should only
be changed by the WESSAMAT service department or an
authorised specialist dealer.
