Dear Customer,
Thank you for purchased a Kenwood Multifunction
Electronic Oven.
The safety precautions and recommendations within this
booklet are for your own safety and that of others. They will
also provide a means by which to make full use of the
features offered by your appliance.
Please preserve this booklet carefully. It may be useful in
future, either to yourself or to others in the event that doubts
should arise relating to its operation.
This appliance must be used only for the task it has
explicitly been designed for, that is for cooking foodstuffs.
Any other form of usage is to be considered as
inappropriate and therefore dangerous.
The manufacturer declines all responsibility in the event
of damage caused by improper, incorrect or illogical use
of the appliance.
IMPORTANT INFORMATION FOR CORRECT DISPOSAL OF THE PRODUCT IN
ACCORDANCE WITH EC DIRECTIVE 2002/96/EC.
At the end of its working life, the product must not be disposed of as
urban waste. It must be taken to a special local authority differentiated
waste collection centre or to a dealer providing this service.
Disposing of a household appliance separately avoids possible nega-
tive consequences for the environment and health deriving from inap-
propriate disposal and enables the constituent materials to be recov-
ered to obtain significant savings in energy and resources. As a
reminder of the need to dispose of household appliances separately,
the product is marked with a crossed-out wheeled dustbin.

IMPORTANT SAFEGUARDS & RECOMMENDATIONS
•Do not carry out any cleaning or maintenance without first disconnecting the
appliance from the electrical supply.
•During and after use of the oven, certain parts will become very hot. Do not
touch hot parts.
•After use always ensure that the controls are in the OFF position.
•Keep children away from the oven during use.
•Do not allow young children or infirm persons to use the appliance without your
supervision.
•WARNING
When correctly installed, your product meets all safety requirements laid down
for this type of product category. However special care should be taken around
the rear or the underneath of the appliance as these areas are not designed or
intended to be touched and may contain sharp or rough edges, that may cause
injury.
•Fire Risk! Do not store inflammable materials inside the oven.
•Always use oven gloves when removing the shelves and food trays from the
oven whilst hot.
•Clean the oven regularly and do not allow fat or oils to build up in the oven
base or trays. Remove spillages as soon as they occur.
•Always stand back from the oven when opening the oven door to allow steam
and hot air to escape before removing the food.
•Do not hang towels, dishcloths or other items on the cooker or its handle – as
this could be a fire hazard.
•Make sure that electrical cords connecting other appliances in the proximity can-
not become entrapped in the oven door.
•Before disposing of an unwanted appliance, it is recommended that it is made
inoperative and that all potentially hazardous parts are made harmless.
•If the supply cord is damaged, it must be replaced by a special cord by a
qualified electrical technician in order to avoid a hazard.

IMPORTANT PRECAUTIONS AND RECOMMENDATIONS FOR USE OF ELECTRICAL
APPLIANCES
Use of any electrical appliance implies the necessity to follow a series of fundamen-
tal rules. In particular:
•Never touch the appliance with wet hands or feet;
•Do not operate the appliance barefooted;
•Do not allow children or disabled people to use the appliance without your super-
vision.
The manufacturer cannot be held responsible for any damages caused by improper,
incorrect or unreasonable use of the appliance.
USING THE OVEN FOR THE FIRST TIME
You are advised to carry out the following operations:
•Furnish the interior of the oven as described under the heading “Cleaning &
Maintenance”.
•Switch the empty oven ON at maximum temperature for about two hours to
eliminate traces of grease and smell from the components.
•Let the oven cool down, switch off, then clean the inside of the oven with a
cloth soaked in water and neutral detergent and dry thoroughly.
BEFORE USING FOR THE FIRST TIME
•Read the instructions carefully before installing and using the appliance.
•After unpacking the appliance, check that it is not damaged. In case of doubt,
do not use the appliance and contact your supplier or a qualified engineer.
•Remove all the packing materials (i.e. plastic bags, polystyrene foam, etc.) and
do not leave it around within easy reach of children, as these may cause serious
injuries. The packaging materials are recyclable.
•Do not attempt to modify the technical characteristics of the appliance, as it
may become dangerous to use.
•The appliance should be installed and all the electrical connections made by a
qualified engineer in compliance with local regulations in force and following the
manufacturer's instructions.

GENERAL FEATURES
This is an oven that presents partic-
ular features from an operational
point of view. It is possible to insert
9 different cooking programs to sat-
isfy every cooking need.
The 9 positions, controlled by the
electronic programmer and a temper-
ature probe, are obtained by 4 heat-
ing elements which are:
• Lower element 1300 W
• Upper element 1000 W
• Grill element 2000 W
• Circular element 2200 W
NOTE:
Upon first use, it is advisable to oper-
ate the oven, at the maximum tem-
perature, for 60 minutes in the posi-
tion and then to eliminate pos-
sible traces of grease on the heating
elements.
Repeat the operation for another 15
minutes with the grill element on as
explained in the chapters GRILLING
and USE OF THE GRILL.
WARNING:
The door is hot, use the handle.
During use the appliance becomes
hot. Care should be taken to avoid
touching heating elements inside the
oven.
OPERATING PRINCIPLES
Heating and cooking in the FULL ELECTRON-
IC MULTIFUNCTION oven are obtained in the
following ways:
a. by normal convection
The heat is produced by the upper and
lower heating elements.
b. by semi-forced convection from the bot-
tom
The heat produced by the lower heating
element is distributed throughout the oven
by the fan.
c. by forced convection
A fan sucks in the air contained in the
oven, which is circulated it through the cir-
cular heating element and then forced back
into the oven by the fan.
Before the hot air is sucked back again by
the fan to repeat the described cycle, it
envelops the food in the oven, provoking a
complete and rapid cooking. It is possible
to cook several dishes simultaneously.
d. by semi-forced convection from the bot-
tom and back
The heat produced by the lower and circu-
lar heating elements is distributed through-
out the oven by the fan.
e. by semi-forced convection
The heat produced by the upper and lower
heating elements is distributed throughout
the oven by the fan.
f. by radiation
The heat is radiated by the infra red grill
element.
g. by double radiation
The heat is radiated by the infra red grill
and the top heating elements.
h. by radiation and ventilation
The radiated heat from the infra red grill
element is distributed throughout the oven
by the fan.
i. by ventilation
The food is defrosted by using the fan and
the bottom heating element (“dEF” mode).
By setting the temperature to higher val-
ues(from 40 to 100°C max) it is possible to
use this mode as a food warmer.
