INTRODUCTION TO THERMOFAN COOKING
Registered by Defy in 1978, Thermofan cooking differs from conventional cooking in
that it uses the principle of forced convection within the oven. The advantages are:
1. Both trays can be used at the same time.
2. Different dishes can be cooked simultaneously without flavour or aroma transfer.
Hence fish, meat and cakes can be baked at the same time.
3. The oven door may be opened any time for inspection purposes without risking a
flop.
4. By circulating hot air around the food, spit-roast chickens may be done without using
a rotisserie.
5. Cooking is done at slightly lower temperatures (10°C TO 20°C lower), saving
electricity and reducing splatter.
THERMOFAN OVEN
• Ensure that the timer is set to manual. Press button 4.
• Set the oven thermostat to the required temperature. The indicator light will glow and
remain on until the oven has reached the selected temperature.
• When the indicator light switches off, the food should be placed in the oven.
• During cooking the indicator light will cycle on and off as the oven thermostat
maintains the selected temperature
• After completion, the thermostat must be returned to the OFF position in an anti
clockwise direction.
Baking guide
• Thermofan baking is done with the oven trays in
position on top of the wire shelves. Unused trays
must be kept in position to facilitate proper airflow.
• For small items the entire area of each tray may be
utilised. Larger items should be placed towards the
front of each tray.
• All ovens extract a certain amount of moisture from the food being cooked. The much
greater capacity of the Thermofan oven allows more food to be cooked and thus more
moisture may be released. This is normal and not detrimental to the food or the oven.
• For professional results and perfect browning, open the oven door when half the
baking time has lapsed. Then turn the baking tins around so that the sides previously
facing the back of the oven now face the front.
• Caution: Thermofan baking relies on good contact between the bottom
of the cake tin and the oven tray. Do not use spring form baking tins with
a raised bottom. The lack of contact will cause the bottom of the cake to
be underdone. These tins may be used on a wire shelf where no
insulating air space is created.

TRAY POSITIONS

GRILLING
• The oven door must remain partially open (about 50 mm)
• Ensure that the timer is set to manual. Press button 4.
• Set the oven thermostat to the GRILL position.
• Pre-heat the roast pan and broiler for 5 minutes
under the grill element to help seal the meat.
• Place the food on the roast pan and place this on a
wire shelf near to the grill element.
• Monitor the grilling process to avoid burning the
food.
• Care must be taken not to touch the grill element
while handling food in the oven.
• After completion, the thermostat must be returned to the OFF position in an anti
clockwise direction.
WARNING:
ACCESSIBLE PARTS MAY BECOME HOT WHEN GRILLING. ALWAYS USE
OVEN GLOVES WHEN HANDLING FOOD IN THE OVEN
AND KEEP CHILDREN WELL AWAY FROM THE PRODUCT WHEN IT IS IN
USE.
WARMING DRAWER
• The warming drawer has a variable temperature control. This allows the correct
setting for the application. An indicator light will glow when the drawer has been
switched on.
• If food is to be kept warm for a lengthy period it is best to select a lower temperature.
• Food left for too long in the warmer drawer could dry out and spoil. As a precaution
food should always be covered, to minimise the drying effect.
• The drawer can be removed for cleaning purposes. Pull the drawer out to the bump-
stop, then lift the front slightly and continue pulling till the drawer slides free.
• Refit by lifting the rear of the drawer over the bump-stop and then sliding it back.

GRILL POSITION

SOLID PLATES
Red dot plates
• Plates featuring a red dot in the centre are high speed, high wattage
plates for increased performance
• For your safety these plates are fitted with thermal limiters. Should
a plate be accidentally switched on and left unattended, the limiter
will reduce the power output of the plate and minimise the risk of
overheating and the possibility of fire.
Caring for Solid Plates
• Before using the plates for the first time, switch them on for about 4 minutes at the
highest setting. This allows the factory applied protective coating to burn in.
• To prevent blotchy discolouration and corrosion, moisture from spatters and spills
should be cleaned off immediately.
• To clean the plates, wipe them with a damp cloth or nylon pad. A little liquid
detergent may be used. Do not use metal scourers or sharp metal objects to clean the
plates.
• After cleaning, dry the plates by switching them on for a short while.
• To prevent rust, periodically apply some, sewing machine oil or electrical hotplate
polish - available from Defy Service Centres. Extra attention is required in areas of
high humidity or in close proximity to the sea.
NOTE: THE WARRANTY DOES NOT COVER THE REPLACEMENT OR
REPAIR OF RUSTED OR CORRODED PLATES.
Recommendations
• Use only pots with a solid level base. An uneven base can prolong cooking times and
waste energy.
• Use pots with a base diameter slightly larger than the plate. This will ensure even heat
distribution and prevent spillage from dripping onto and staining the hot plate.
• Always cover the pot with a lid. This will conserve energy and minimise spillage.
• Thermal shock could damage the plates. Do not put cold pots on very hot plates.
Plate controls—variable
• Select the heat level by turning the knob to the required
setting.
• You may select any setting.
• 1= low, 3 = medium and 6 = high.
• The relevant plate indicator light will glow, when the plate
is switched on.

CERAN SMOOTH TOP
WARNING In the unlikely event of sustaining accidental damage and cracking, switch
off the appliance at the mains to avoid electric shock and have the panel replaced before
further use.
Caring for the Ceran hob
• Ceran is a tough, durable material, which provides a beautiful, functional and long
lasting cooking surface. To keep it looking good, it needs to be treated with care and
cleaned regularly.
• Spillage should be wiped off as soon as possible with a damp cloth, preferably while
the hob is still warm.
• Clean the hob with a nylon pad and ‘Smooth top cleaner’. A sample of this cleaner is
supplied with the unit. Replenishment cleaner is available from all Defy Service
Centres.
• If necessary stubborn spills may be removed using the blade scraper provided.
• Do not use metal scourers or coarse abrasive powders as these could scratch the
Ceran.
• Regular cleaning after use will prevent dirt build up and ensure that the hob remains
bright and attractive.
• Wipe the hob surround with a damp hot soapy cloth and dry.
Plate controls—variable
• Select the heat level by turning the plate control knob to the required setting. You
may select any setting, even between numbers. 1= low, 4 = medium and 8 = high.
• The relevant pilot light will glow and shortly thereafter the hot surface indicator light
on the hob will glow. It will remain on for 20 to 30 minutes after switch off. This is a
reminder that the hob surface is still too hot to touch.
Recommendations (see also the enclosed ‘CERAN’ leaflet)
• Use only pots with a solid level base. An uneven base will prolong cooking time and
waste energy.
• Use pots with a base diameter slightly larger than that of the thermal area. This will
ensure even heat distribution and prevent spillage from dripping onto and staining the
hot zone.
• Always cover the pot with a lid. This will conserve energy and minimize spillage.
• Save energy by switching the plate off 5 to 10 minutes before the end of a lengthy
cooking period. The Ceran hob will retain sufficient residual heat to complete the
cooking process.
• A pot with rough edges could scratch the Ceran if it were dragged across the surface
of the hob.
• Any spillage of sugar solution such as jam, must be removed immediately. If allowed
to cool on the Ceran it could pit and damage the surface.
Do not cover the Ceran with aluminium foil and do not use poor quality aluminium pots.
These will leave unsightly deposits which in time, could adhere to the Ceran.

MAINTENANCE
Cleaning the oven
• Switch off the electrical power supply before cleaning any part of the appliance.
• Open the oven door and allow the oven to cool down.
• For improved access, the shelves, trays and oven door may be removed. (see details
below)
• Clean the oven with a damp, hot soapy cloth.
• It may be necessary to soak burnt soils with a liquid cleaner to soften them before
scrubbing them with a nylon brush or scouring sponge.
• Heavy soils on the bottom of the oven may require overnight soaking under a sponge
liberally sprinkled with household ammonia. The soil can then be removed the
following morning by washing normally.
• Do not use metal objects or steel wool to clean the oven
