Preparation
Tips for energy saving
The following information will help you to
save energy:
• Defrost frozen dishes before cooking.
• Select the burner which is suitable for the
bottom size of the pot to be used. Always
select the correct pot size for your dishes.
Larger pots require more energy.
• Pots with a thick base will provide a better
heat conduction. You can obtain energy
savings up to 1/3.
• Pots must be compatible with the cooking
zones. Bottom of the pots must not be
smaller than the hotplate.
• Always cover the pot with a lid. This will
conserve energy and minimize spillage.
Initial use
First cleaning of the appliance
1. Remove all packaging materials.
2. Wipe the surfaces of the appliance with a
damp cloth or sponge and dry with a
cloth.
The surface may get damaged
by some detergents or cleaning
materials. Do not use
aggressive detergents, cleaning
powder/cream or any sharp
objects.

• Position the hob into the aperture so that
the securing clips are compressed
between the hob base and the worktop.
(see Sketch below).
Since the following are not factory faults,
they are the owner’s responsibility.
• Damage to exterior finish.
• Breakage of glass and other components.
• Damage through improper use or
installation of the appliance.
• Damage caused by moving the appliance.
• 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.
• Keep the cooking zones and bottom of the
pots clean. Dirt will decrease the heat
conduction between the cooking zone and
bottom of the pot.
• Use only pots with a solid level base. An
uneven base will prolong cooking time and
waste energy.
• Save energy by switching the plate off 5 to
10 minutes before the end of a lengthy
cooking period. The hob will retain
sufficient residual heat to complete the
cooking process.
• A pot with rough edges could scratch the
appliance surface if it were dragged
across the surface of the appliance.
• Any spillage of sugar solution such as jam,
must be removed immediately. If allowed
to cool on the surface it could pit and
damage the surface.
• Do not cover the appliance surface with
aluminium foil and do not use poor quality
aluminium pots. These will leave unsightly
deposits which in time, could adhere to the
surface of the hob.
• Only use clean pots with an even flat base
to prevent cracking on glass due to hot
spots.

Display the remaining time value of the
cooking zone timer 3 (indicator LED flashes)
to the timer display (the indicator LEDs of
the active timers of the cooking zones 1 and
4 in fact will not be visible on the timer
display).
Keep warm function (if any)
Keep Warm function of the cooking zone
helps to keep the food warm by selecting an
additional temperature level between 0 and
1. Touch" " key to activate the Keep Warm
function.
Then, " " LED flashes. Touch " " key
again to disable the cooking zone.
Operation time constraints
The hob control is equipped with an
operation time limit. When one or more
cooking zones are left on unintentionally, the
cooking zone will automatically be
deactivated after a certain period of time.
(see, Table-1).

Page 17
Operation time limit depends on the selected
temperature setting. If there is a timer
assigned for the cooking zone, "00" appears
on the timer display for 10 seconds (10
seconds later, residual heat indicator turns
on). Then, timer display is turned off. After
disabling the cooking zone automatically as
described above, it becomes operational
again and maximum operation time is
applied for this temperature setting.
Hob control system should also not be
exposed to strong light sources such as sun
light, strong halogen lamps and etc.

Residual Heat Functions
For a deactivated cooking zone whose
surface temperature is sensed to be above
60°C or whose display indicates a value
above 60°C, a " " (residual heat) symbol
appears on the display. When residual heat
falls below 60°C, "0" appears on the display.
Sample application:
Following lightning conditions will allow
a smooth calibration:
Illumination with a bulb without a reflector
(100W, dull) 70 cm above the hob. After
successful calibration, it is warranted that the
hob will operate as intended even under
strong illumination such as halogen spot
lamp with reflector (50 W).
If an error occurs, calibration is repeated
until the ambient conditions allow for a
successful calibration. Hob control system
can only be operated when the calibration of
all sensors are successful.
Remove all substances on the hob during
calibration. The ambient illumination should
not be too strong during calibration. If an
error messages is obtained, turn off all light
sources or close the window during the
calibration process. When the calibration is
completed successfully, the control system
can tolerate high amount of ambient light.
The control system adopts and recalibrates
itself according to the changes in ambient
conditions while in use.
Touch control has a sensor that
protects from overheating. The
cooking zone will be deactivated
when reacting to the sensor. Refer
to table 2 about error messages. If
a key is activated repeatedly,
control system is deactivated and
audio signal is given.
When power restores after a
power failure or your Hob is
switched off if the residual heat of
the relevant cooking zone was
above 60°C before the failure,
residual heat display flashes.
Display continues to flash until the
maximum residual heat time is
over or the cooking zone is
selected and enabled

PROBLEM
The plates do not work / Check there is
power to the wall switch.
The timer on Gemini hobs make a clicking
noise / This is normal. Timers do make a
clicking noise.
Remember that you may be charged for a
service call even during the warranty period
if the fault is due to or caused by any of the
above.
Problem check
Before calling a service technician to assist
with a problem
Caring for the hob
• Vitroceramic is a tough, durable material,
which provides a beautiful and long
lasting cooking surface. To keep it looking
good, it needs to be cleaned regularly.
• Clean the product thoroughly after each
use. In this way it will be possible to
remove cooking residues more easily,
thus avoiding these from burning the next
time the appliance is used.
• Wipe the glass ceramic surface using a
piece of cloth dampened with cold water
in a manner as not to leave any cleaning
agent on it. Dry with a soft and dry cloth.
Remaining residues may cause damage
on the glass ceramic surface when using
the hob for the next time.
• If the surface is heavily soiled, apply a
suitable smooth top cleaning solution
(available from Defy Service Centres) on
a sponge and wait until it is absorbed well.
Then, clean the surface of the hob with a
damp cloth.
• Wipe the hob surround with a damp hot
soapy cloth and dry.
• Remove calcium stains (yellow stains) by
applying a small amount of lime remover
such as vinegar or lemon juice. Other
suitable commercially available products
can also be used.
• Dried residues on the glass ceramic
surface should under no circumstances
be scraped with hook blades, steel wool
or similar tools.
• If necessary stubborn spills may be
removed using an approved blade
scraper.
• Always ensure any excess liquid is
thoroughly wiped off after cleaning and
any spillage is immediately wiped dry.
• Do not use cleaning agents that contain
acid or chloride to clean stainless or inox
surfaces. Use a soft cloth with a liquid
detergent (not abrasive) to wipe those
parts clean, paying attention to sweep in
one direction.
• Only use clean pots with an even flat base
to prevent cracking on glass due to hot
spots.
WARNING: In the unlikely
event of the Vitroceramic
sustaining accidental damage or
cracks, switch off the appliance
at the mains to avoid an electric
shock and have the panel
replaced before further use.
Recommendations
• 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 Vitroceramic hob will
retain sufficient residual heat to complete
the cooking process.
• A pot with rough edges could scratch the
Vitroceramic surface 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 Vitroceramic
surface it could pit and damage the
surface.
• Do not cover the Vitroceramic surface with
aluminium foil and do not use poor quality
aluminium pots. These will leave unsightly
deposits which in time, could adhere to
the Vitroceramic surface.
