The filters indicated are:
- No filter for chloride (Cl-) in the conforming area (Normal)
- Nanofilter
as an accessory on request, called Water Filter.
- Osmotizer.
Make sure the water coming out the filter is inside the optimum
area (Normal).
These filters also have the function of reducing the water
hardness to optimum values (below 5°f), and therefore also act
as a water softener.
ATTENTION:
Periodical checking according to the filter
manufacturer’s instructions is important to maintain its efficiency
and avoid the risk of corrosion in the appliance.
Level C ovens are convection ovens. If water having
characteristics outside those specified is used to create humidity
inside the oven, there will be the risk corrosion of the compartment
and that present inside it.
Carry out regular maintenance of the water softeners and filters
to ensure their optimum efficiency.
To avoid damage to the appliance, after every periodical
regeneration do a filter cleaning cycle without introducing water
in the oven.
The manufacturer declines any liability in case of incorrect
maintenance.
Important:
The use of dosing systems designed to prevent the build-
up of lime-scale in pipes (i.e. polyphosphate dosing
systems) is prohibited since such systems may impair the
performance of the appliance.
For UK and COMMONWEALTH only:
In accordance with "the water supply (Water Fittings)
Regulations 1999", it is mandatory that this appliance when
installed to the mains water supply has fitted an approved
"double check valve" connected upstream of the appliance.
Failure to comply with these regulations may lead to the
appliance being disconnected.
4.2 WATER DRAIN SYSTEM
- OVEN level A -
The oven is supplied with an air-break system to prevent any
backflow from the drainage system from reaching the oven’s
internal circuits and the cooking chamber. The presence of this
system means that the drain pipe can be connected directly to
the mains drainage system or routed to a floor gulley with grat-
ing.
The flexible drainage hose or rigid pipe can be directed to the
side or rear of the appliance if the oven is not positioned against
a wall; this line must not be directed towards the front of the
appliance to prevent interference with roll-in grid racks. The drain-
age pipe internal diameter must be no smaller than the oven
drain outlet (1” 1/4),
no longer than 1 metre
and must resist
temperatures of up to at least 100°C. Avoid restrictions in the
case of flexible hose pipes, do not fit elbows on metal pipes
anywhere along the drainage line. Also avoid horizontal sec-
tions in which water might collect (minimum gradient 5%).

Safety outlet
Important:
-
Do not obstruct the safety outlet
C1
.
- Do not connect the safety outlet
C1
to the drainage system.
Note:
If water comes out of the AIR-BREAK (safety outlet C1) this means
the drain C is blocked. Any elimination of the obstruction
must
be carried out by specialised technical personnel.
- OVEN level B and C -
Connect drain fitting “C” to a drain pipe of the same diameter
which is between 0.5 and 3 metres in length and is resistant to
temperatures of at least 100°C. The drain pipe must be siphoned
(height 80 mm) to an open drain “O” (“Air-Break”) or floor grating
(see Fig. 12b) in order to prevent any back-flow from the sewage
system from reaching the piping inside the oven or oven chamber.
Check the hoses and elbows on metal pipes for kinks or pinching
along the entire drain line and make sure the drain line has a
minimum gradient of 5° to prevent water from collecting inside
the
system.
Important
: The drain system must be installed so that any
vapours from the open drain do not enter the aeration vents
under the appliance.

5. SAFETY DEVICES
The appliance is fitted with the following safety devices:
- Fuses
(see electrical circuit diagram) located behind the control
panel.
To change a fuse unscrew and remove the retainer cap and
replace the blown fuse with an identically rated component; the
fuse rating value is specified on the relative dataplate.
