ATTENTION:
The periodical check of fi lter effi ciency, according
to that indicated by the manufacturer, is important to avoid com-
promising appliance operation and the risk of corrosion.
Level C ovens are convection ovens. The use of water with
non-conforming characteristics inside the oven compartment for
generating humidity creates the risk of corrosion of the compart-
ment and its contents.
Regular maintenance of water softeners and fi lters is necessary
to ensure their effi ciency.
To avoid damaging the appliance, with every periodical regeneration
do a fi lter cleaning cycle without introducing water in the oven.
The manufacture declines any liability in case of incorrect main-
tenance.
Attention:
Dispensers of substances for preventing scale in
the pipes (e.g. polyphosphate dispensers) must
not be used because they can compromise correct
appliance operation.
4.2 WATER DRAINING SYSTEM
The oven has an AIR-BREAK anti-backfl ow device inside to
prevent any backfl ow from the drainage system entering the
internal pipes and the oven compartment. This allows the drain
pipe to be connected directly to the mains system or discharging
into a fl oor grate.
The drain pipe (rigid or fl exible type) can be run to the side or back
if the oven is not placed against a wall, excluding the front part
with rack support structure. It must
not be more than 1 metre
long, with inside diameter not less than that of the oven discharge
pipe (1" 1/4), and must withstand temperatures of at least 100°C.
Make sure there are no constrictions in hoses or elbows in metal
pipes, along the entire drain path. Avoid horizontal sections where
water can collect and stagnate (min. slope 5%).

Attention:
-
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) it means
the drain C is blocked. Elimination of the obstruction
must be
carried out by specialised technical personnel.
5. SAFETY DEVICE
The appliance is equipped with the following safety devices:
-
Fuses
, see the wiring diagram, located behind the control panel.
For replacement, unscrew the cap and replace the damaged
component with another one having the same rating; this value
is given on the label located in the same place.
-
Compartment manual-reset safety thermostat
located behind
the control panel; it shuts off the gas supply to the convector burner.
-
Steam generator
manual-reset safety thermostat
located
behind the control panel; it shuts off the gas supply to the gene-
rator burner.
Resetting operations must be carried out by specialised technical
personnel after eliminating the causes of interruption.
-
Automatic-reset thermal device
inside the
fan
, which is acti-
vated if the fan overheats, protecting unit operation; it cuts off the
electrical power to the appliance.
6. OPERATION CHECK
-
Switch the appliance on, as described in the section "Operating
instructions";
- Explain appliance operation, routine maintenance and cleaning
operations to the user, with the help of the instruction handbook.
Attention:
- During operation, pay
attention to the hot areas of the exterior surface.
- Do not place objects on the outlets located at the
top of the appliance.
- With oven hot, check the correct working of the door closing
mechanism. If necessary, adjust closing by adjusting the position
of the catch.
17. MAINTENANCE
The components requiring routine maintenance are accessible
by opening the control panel, and left and rear panels.
18. BRIEF TROUBLESHOOTING GUIDE
Even with correct use of the appliance, malfunctions can occur.
Oven chamber heating not started or ineffi cient.
Possible
causes:
- Oven chamber temperature limit switch tripped
- Damaged heating elements
- Damaged heating element contactor coil
- Damaged thermostat probe showing error “EPt1”.
- Damaged controller
- Fuse “F2” blown, see circuit diagram.
Steam production not started or ineffi cient.
Possible causes:
- Damaged heating elements
- Damaged heating element contactor coil
- Damaged controller
- Fuse “F2” blown
- No mains water supply
- Faulty boiler drainage outlet closing device
- Damaged water inlet solenoid valves (do not open)
Oven chamber temperature reading incorrect
Possible causes:
- Damaged electronic controller
- Thermostat probe damaged, dirty or interrupted, see error “EPt1”.
Oven switches off
Possible cause:
- Fuse “F2” has blown due to damage of control circuit components.
Oven chamber lamp fault
WARNING
: Switch off the appliance before changing oven
chamber lamps.
9. POSITIONING OF MAIN COMPONENTS
(Any operation inside the appliance must only be carried out
by an installer authorised by the Manufacturer).
Removing the control panel provides access to the following
components:
- Electronic circuit boards
- Oven chamber temperature limit thermostat
- Fuses
- Door microswitch
- Oven chamber lamp transformer
- Geared motor for the oven chamber pressure relief butterfl y valve.
To gain access to all other components remove the appliance’s
left and rear side panels.
