6. Working Instructions & Operation Flow
6.1 Operating the Controls
A convection oven is a different type of oven that offers many features and advantages to the food
service operation. The additional capabilities and features of the oven require some learning. However,
the operation of the oven is not difficult to understand or control once you have some practice. See the
controls in the following feature:

8
6.2 Operations
Turn the oven ON and select a cooking temperature. Two additional controls are used to control the
fan (as described below).
The timer is a reminder to you of when to remove food from the oven. The timer does not control the
temperature of the oven.
Fan Mode:
In COOK mode, the fan runs continuously
except when the doors are open. The fan does
not cycle with the operation of the burners. In
COOL mode, the fan runs continuously even if
the doors are open. To rapidly cool the oven
after cooking is completed, open the doors and
switch the fan mode to COOL.
Power Switch:
Switch ON to use the oven, switch
OFF when do not use.
Cook Timer:
Turn knob to set a time duration. An
alarm will sound when the timer runs
out. Turn the knob to OFF to cancel
the alarm. The timer is a reminder to
the user; the timer does not control
the oven.
HEAT-ON Indicator:
The HEAT-ON indicator will light
when the burners are on and will
remain on while the oven preheats.
Power light
Switch ON，and the light on.
Switch OFF，and the light off.
Cook Temperature Control:
Turn the knob to desired temperature.
When the set point is reached, the
HEAT ON indicator will be off. When
the burners maintain in the set
temperature, the indicator will cycle on
or off.
。
HI/LOW Fan Speed:
Use to select fan speed (HI or LOW). The
appropriate speed is determined by the
type of food being cooked.
Oven Interior Light Switch:
Press to turn on the light.
The light is controlled independently.

9
To cook, do the following:
1. Turn the oven ON using the Power Switch at the top of the control panel.
2. Select the desired fan speed using the Fan Speed switch. The appropriate fan speed (HI or LOW)
depends on the type of food being cooked.
3. Switch the Fan Mode switch to COOK. The fan will run continuously when the oven doors are
closed (the fan does not cycle on and off with the burners). (If this switch is set to COOL, the only
difference is that the fan will continue to run when the oven doors are open.)
4. Set the cooking temperature by turning the Cook Temperature Control until the indicator mark on
the knob is pointed to desired cooking temperature. The HEAT ON indicator will light when the
burners are on and will remain on while the oven preheats.
5. Wait until the HEAT ON indicator has come on and gone out three times.At that time the oven will
have reached the set cooking temperature.
6. Open the oven doors, load the product into the oven, and close the doors.
7. You can use the Cook Timer as a reminder of when to remove the load from the oven. If so
desired, turn the Cook Timer knob until the indicator mark points to the desired cooking time (up
to 60 minutes). The timer knob will rotate counterclockwise as the timer runs down, indicating
how much time remains. You can turn the knob while cooking to increase or decrease the
remaining time. When the timer runs out, a buzzer will sound (To immediately silence the buzzer,
turn the Cook Timer knob to the OFF position.) The timer is a reminder to you; the timer does not
control the oven.
If you open the oven doors, the burners and fan will shut off until the doors are closed. However,
the timer will continue running even if the doors are open.
For ovens that are equipped with an oven interior light, to turn on the light, press and hold the
switch located at the bottom of the control panel.
8. When the load has finish cooking, you can rapidly cool the load by opening the oven doors (which
will shut off the burners) and switching the Fan Mode to COOL (which will cause the fan to run
even though the doors are open). For the most rapid cooling, also switch the Fan Speed switch to
HI.
9. When you are done cooking, turn the Cook Temperature Control to the lowest setting (fully
counterclockwise) and switch the Power Switch to OFF.

8. Cleaning & Maintenance
1. Before cleaning, switch off the unit and let it cool down.
2. Carefully clean daily the appliance to guarantee its proper operation and long life.
3. Steel surfaces must be cleaned with a dish washer detergent diluted in very hot water by using a
soft cloth; for the toughest dirt, use ethylic alcohol, acetone or another non-halogenated solvent;
do not use abrasive powder detergents or corrosive substances such as hydrochloric acid,
muriatic or sulphuric acid. The use of acids can affect the unit’s operation and safety. Do not use
brushes, steel cottons or abrasive disks made with other metals or alloys that might cause rust
stains due to contamination. For the same reason, avoid contact with iron objects. Do not use
steel cottons or stainless steel brushes because whilst they will not contaminate surfaces, they
can cause damaging scratches.
4. Metal powder, metal shavings from working and iron material in general, when in contact with
stainless steel surfaces, can cause rust stains. Superficial rust stain might be present on new
appliances and they can be removed with a detergent diluted in water and a Scotch Brite sponge.
If dirt is tough, do not use sandpaper or rough paper, but use synthetic sponges (for example
Scotchbrite sponges).
5. Do not use substances for cleaning silver and be careful with hydrochloric or sulphuric vapors
coming from floor washing products, for example. Do not aim water jets directly on the appliance,
it might be damaged. After cleaning, rinse properly with clean water and dry carefully with a cloth.
6. The appliances are made in a way that little maintenance is necessary. Despite this, we
recommend that the user subscribes to a maintenance agreement to have the appliance checked
at least once a year by the specialized personnel of our assistance service or by a specialized
technician.
7. Before carrying out any maintenance or repair, disconnect the appliance from the gas
network or cut off the mains. Use only original spare parts supplied by the manufacturer.
8. If the appliance is not used for long period of time, please clean the equipment and the
surrounding areas properly. Pour a small quantity of cooking oil on the stainless steel surfaces.
Carry out all maintenance operations. Cover all appliances with a suitable material and leave a
few openings to allow air to circulate.
