Oven Controls and Use
Cooking function knob
To set the function, turn the cooking function knob for the required
oven clockwise to the required function. Each of the oven functions
uses different elements within the oven to offer you the best choice of
cooking every time. These are explained below:
Conventional oven
This function uses the top and bottom heating elements only
with a temperature between 50ºC and 250ºC.
Natural convection creates a perfect cooking zone in the
centre of the oven, ideal for dark fruit cakes and pastries.
Warming oven
This function uses the bottom heating element only with a
temperature set between 50ºC and 250ºC. This natural heat is
perfect for dough proving and blind-baking.
Grill
This function radiates the heat from the grill element and the top
element.
This fully temperature variable grill is ideal for grilling a full family
meal. It can be set between 50ºC and 250ºC.
When grilling, please note:
• Always grill with the oven door closed.
• Put the grill pan as close to the grill as possible.
• Do not grill for more than 30 minutes at a time.
• Preheat the grill for approximately five minutes with the oven door
closed.
7
Oven Lamp
This function switches on the oven light in the cavity.
Please note: the oven light will operate on all cooking functions.
Defrost
Using the fan only this oven function circulates the air around
the oven cavity, speeding up the natural defrost process (1kg
takes approximately one hour, depending on the type of food).
Fan Oven
Using the circular element and the fan with a temperature
between 50ºC and 250ºC, this cooking function blows the air
into and around the oven cavity. Temperatures are achieved
quicker, reducing or even removing the need for preheating.
Both cooking temperatures and cooking times can be
reduced for a more energy efficient cooking programme.
This function is perfect for cooking various food types simultaneously
as foods are sealed quickly to prevent flavour transfer.
Temperature knob
• To set the temperature, turn the temperature knob for the required
oven clockwise to the required temperature.
• Once the oven has reached the required temperature, the
temperature indicator lamp on the control panel will switch off.
• The temperature indicator lamp will light up when the oven elements
are working.

Care and Maintenance
IMPORTANT
Before any maintenance is started, the appliance must be
disconnected from the power supply.
If the oven has been in use, let the oven cavity and the heating
elements cool down before attempting any maintenance.
The oven exterior
As the oven has a stainless steel or enamel surface, you should
use a nonabrasive cleaner. Any abrasive cleaner (including Cif) will
scratch the surface and could erase the control panel markings.
Stainless steel can be effectively cleaned by simply using a dilute
solution of water and mild detergent and drying to a shine with a
clean cloth.
Proprietary stainless steel cleaners are available. We recommend the
a clean, dry microfibre cloth for cleaning stainless steel surfaces as
this has been designed to prolong the finish of your appliance.
The oven interior
The oven should always be cleaned after use when it has cooled
down.
The cavity should be cleaned using a mild detergent solution and
warm water.
Suitable proprietary chemical cleaners may be used after first
consulting with the manufacturers’ recommendations and testing a
sample on a small area of the oven cavity. Abrasive cleaning agents
or scouring pads/cloths should not be used on the cavity surface.
13
IMPORTANT:
• Steam cleaners must not be used when cleaning this appliance.
• Once care and maintenance is complete, ensure that all parts are
correctly replaced before using the oven.
Changing the Oven Lamp
Before any maintenance is started, the appliance must be
disconnected from the power supply.
If the oven has been in use, let the oven cavity and the heating
elements cool down before attempting any maintenance.
Always wear gloves when handling bulbs, particularly new ones,
to preserve the maximum lifetime of them.
Changing the bulb (fig. 2)
Unscrew the protective cover. We
recommend that you wash and dry
the glass cover at this point.
Carefully remove the old bulb and
insert the new bulb suitable for high
temperatures (300ºC) having the
following specifications: 230-240V,
50Hz, 25W, G9 fitting.
Refit the protective cover.
IMPORTANT
Never use screwdrivers or other utensils to remove the light cover. This
could damage the enamel of the oven or the lamp holder. Remove
only by hand.

Installation
Important
Failure to allow adequate ventilation to the appliance may result in
overheating or damage to adjacent units and could invalidate the
warranty. The diagram below shows the minimum required.
This appliance is type X installation. The walls of the kitchen units must
be able to withstand temperatures of 75°C above ambient (typically
this is between 90°C and 100°C).
When correctly installed ensure that there is a gap of 4mm minimum
between the sides of the oven and adjacent furniture doors.
Lift the oven carefully into position on the shelf, taking care NOT to
lift it by the door handles. If you lower the oven door, you will see 4
screw holes, 2 on each side of the oven. The oven should then be
secured to the housing by fitting screws into these holes. Remember
the housing should not be free standing but be secured to the wall
and/or adjacent fittings.
How to install your oven
You will need the housing area shown on page 16 in order to fit your
oven correctly.
MD721 only: We recommend that you fit end support panels onto the
adjacent units to allow the oven to be secured in place (as shown in
fig. 8).
