2 | Connections to be made to the oven (control panel 9080)
2.1 STEAM, WATER, DRAIN AND ELECTRICAL CONNECTIONS
STEAM OUTPUT
To ensure a successful baking process, the steam output
must be independent from the exhaust output.
Install an aluminum tube of 80mm in diameter to separate
the steam output from the exhaust output.
WATER INPUT
The connection of water to the oven should have the follow-
ing characteristics:
- A pressure between 43 and 50 PSI;
· If pressure is below this gure install a water pressure
booster pump.
· If pressure is above this gure, install a pressure regula-
tor.
- It is advisable to apply a water softener before connect-
ing the water to the oven, in order to avoid sedimenta-
tion of limestone in the steam parts, as this will prolong
its life and improve its eectiveness.
DRAIN
Connect the drain to the sewage system. The connection
must be lower than the oven prover bath (when applicable).
ELECTRICAL POWER INPUT
The client should install an individual circuit breaker
that meets the oven power data plate specifications.

4.1 OPERATION OF CONTROL PANEL 9080
The control panel will automatically carry out a series of ac-
tions which ease the baking process. The actions that you
would have to carry out throughout a baking cycle, namely
start the timer, inject steam, change the baking temperature,
are done automatically and you only needs to press the cycle
button on the control panel.
SETTING THE TEMPERATURE
Press the TOP or STONE button to access temperature selec-
tion for TOP and STONE. The correspondent display and but-
ton will ash. Use the and buttons to select the
desired value and validate by pressing the corresponding
ashing button (TOP or STONE).
SETTING THE ELECTRIC POWER FOR FRONT-TOP
AND FRONT-STONE
Lightly press the button to select the electric power
for FRONT-TOP and FRONT-STONE. The value for FRONT-TOP
electric power is seen on the TOP display in % over the TOP
electric power. To validate press the button. Following,
the value for FRONT-STONE is seen on the STONE display in %
over the STONE value.
SETTING THE BAKING TIME
Lightly press the button to select the desired baking
time in minutes. The clock button and display will ash. Fol-
lowing, set the time and conrm by pressing the button
again.
STEAM INJECTION
Press the button for 2-3 seconds to have steam
injection.
STEAM READY
button. When the steam button is flashing it
means that it is not possible to inject steam as the
temperature is still below the required value.
As soon as the button stops flashing, the steam injection
sys-tem is ready to inject steam and the baking cycle can
start.
END OF BAKING WARNING MESSAGE
You can program the duration of the “end of baking” warn-
ing message in seconds. Press the button for two sec-
onds and the pilot light and superior display will ash. The
display will show the actual duration of the warning mes-
sage. Dene the desired duration and save by pressing the
button again.
TEMP
TEMP
When the baking cycle starts, the timer will show the remain-
ing time until 0 is reached. An acoustic signal indicating the
end of the baking cycle will be heard. This signal is activated
intermittently by the relay and is on for the pre-set period of
time. Press any button to cancel the warning.
If the baking cycle is not stopped when the baking time is over,
the timer will continue to add time and the oven will continue
baking.The clock will be intermittent to alert you to this situa-
tion. In the following 2nd, 4th, 6th, 8th and 10th minutes the
control panel will activate a brief intermittent warning sound.
In the 10th minute the control panel ends the baking cycle
automatically.
4.2 ADDITIONAL FUNCTIONS
OVEN LIGHT
Enables one to turn the oven light on and o.
EXHAUST BUTTON
Enables one to turn the oven exhaust system on and o.
ECONOMISER BUTTON
This control panel has a system that reduces instant con-
sumed electric power (Economiser) and ensures that the in-
stant consumed electric power does not surpass 50% of the
electric power installed in the chamber.
To select the desired ECO value, you must press the
button. This button will be lit while it is activated.
The maximum consumption value in Kw is indicated when-
ever the economiser is activated. It indicates a value which
will not surpass the value set in the control panel with regard
to the total value that you can dene.
BUTTON TO HEAT THE STEAM GENERATOR
This button activates the steam generator.
If this function is o the generator is also o and does not
heat steam or enable steam injection to occur. When the
steam generator is activated you will hear an acoustic sound
and the button lights up.
You may see the actual temperature of the steam generator
by pressing the button , for two seconds.

5.3 MAINTENANCE OF GLASS DOORS
5.2 TIGHTENING THE SPRINGS AND DOOR STOPS
5.1 GENERAL CLEANING OF THE OVEN
CLEANING THE GLASS DOORS
With time the glass doors build up sediments.Therefore, they
must be cleaned on a regular basis.
Use warm water (between 30-40ºC) to clean the glass. It
should not be cleaned with cold water as the temperature
dierential may cause the glass to break. A suitable detergent
may also be used.
REPLACING THE GLASS OF THE DOORS
Proceed as follows to replace the glass of the doors:
1. Remove the glass by unscrewing the screws (see g. 3)
2. Place the new glass in the right position.
3. Tighten the screws (to prevent the glass from breaking,
the screws should not be too tight).
Follow the same procedure to replace the inner glass. Use a
high temperature silicone to seal the inner glass.
The oven must be cleaned on a regular basis and whenever
needed to prevent the formation of crusts that cannot be ea-
sily removed.
Cleaning must be done as follows:
1. Never soak the oven electrical or electronic parts in
water. Do not use abrasive products (sandpaper, etc) as
they may scratch the oven.
2. Use an appropriate cleaning product to clean stainless
steel surfaces.
3. Use a damp cloth to clean the external surfaces (except
for the control panel).
Adjust compensation springs on the doors. Follow instruc-
tions below.

MAINTENANCE WARNINGS
Notwithstanding the fullment of the aforementioned dead-
lines, the oven has a system that warns the operator of the
need to carry out periodic maintenance. This warning is a gen-
eral preventative warning. For such, the shorter term mainte-
nance tasks must be carried out regardless of there being a
warning signal.
This warning shows up with the message on the dis-
play. This message will be shown on the display as long as the
condition that triggered the warning persists.
After the maintenance process has been concluded, the warn-
ing must be cancelled as it will reappear in a programmed
manner.
In order to do so, proceed as follows:
1. Press the button for 3 seconds to access the param-
eter .
2. Press the button for 3 seconds to reset the number
of hours remaining until the next maintenance warning
appears.
3. Press the button to validate and exit the menu.
