STANDARD FILTER SYSTEMS
A) Fine filter
If the water contains impurities such as sand, iron particles or floating substances, we recommend the use of a fine
filter at the water input.
B) Activated carbon filter
If the water has a high chlorine content over 0.2 mg/l (this information can be obtained from the relevant water
board), an activated carbon filter should be installed.
C) Installation of osmosis recirculation
When the chloride concentration is above 150 mg/l (this information can be obtained from the relevant water
board), an osmosis recirculation installation should be mounted. In this case, please remember that the minimum
conductivity value is 400 µS.
D) Water descaling
For water with a high level of lime scale (without chloride load) the water should be treated. Systems: H+.
Interchange of ions or Kleensteam. We strongly advise against the use of sodium/ion exchangers (normally used in
dish washers) due to the formation of sodium sediment and the delay in boiling with common salt.
When selecting filter systems (A, B, C, D), we recommend you contact a specialist water treatment company.
8.3. WASTE WATER CONNECTION
Incorrect installation of the appliance may result
in the incorrect operation of it.
A drainage must be installed for this (DN40).
The installation should be in such a way as to
ensure that the installed drainage outlet is below
the oven outlet with a suitable slope to ensure
drainage (≈ 5 ÷ 3%) .
Ensure the measurements for the drainage are
correct.
Average temperature of waste water: 65 ºC.
Once the drainage has been installed, the
discharge to the general drainage must be via a
type `AA`, `AB` or `AD` change in water level in accordance with EN 1717.
The machine drainage hose must be connected to the drain so that water draining from
the machine flows freely under gravity; therefore, the drain must be lower than the
drainage hose.
If the drain is higher, it will be necessary to use an machine fitted with a drainage pump.
The maximum permitted height of the drain is 500 mm above the drainage level of the
machine. The pump may be requested at the time of purchase or installed subsequently.
The drainage pump must only be installed by personnel authorised by the
manufacturer, and the manufacturer does not accept liability in the event of
incorrect installation.
The machine drainage hose must be connected to a sump with a drain trap to prevent the
return of bad odours.
Check that the drainage system operates correctly and is not blocked.
