Instructions and Installation
• Fire safety advice
• Most kitchen fires occur when people are distracted or leave things
unattended, so remember:
• If you’re called away from the hob – by the phone or someone at
the door, either take pans off the heat, or switch off your hob.
• Don’t let yourself be distracted while cooking. Do not leave unattended.
• If you do have a fire in the kitchen, don’t take any risks – get everyone
out of your home and call the Fire Service.
If a pan catches fire
• Do not move it as it’s likely to be extremely hot.
• Turn of the heat if it’s safe to do so, but never lean over a pan
to reach the controls.
• WARNING: Use fire blanket or a damp tea-towel to cover the pan.
Deep-fat frying presents more dangers in your kitchen
• If you have put the fire out, leave the pan to cool completely.
• Never fill a chip pan (or other deep fat fryer) more than one-third
full of oil.
• Do not use a fire extinguisher on a pan of burning oil – the force of
the extinguisher can spread the fire and create a fireball.
If you have an electrical fire in the kitchen
• Switch off the power at the fuse box – this may be enough to stop
the fire immediately.
• Smother the fire with a fire blanket, or use a dry powder or carbon
dioxide extinguisher.
• REMEMBER: Never use water on an electrical or cooking oil fire.

Instructions and Installation
The following information will
help you to use your appliance
in an ecological way, and to
save energy:
• Defrost frozen dishes before
cooking them.
• Use pots/pans with cover for
cooking. If there is no cover,
energy consumption may
increase 4 times.
• Select the burner which is
suitable for the bottom size
of the pot to be used. Always
select correct pot size for your
dishes. Larger pots require
more energy.
• Pay attention to use flat bottom
pans when cooking with
electric hobs.
• Pots with thick a thick bottom
will provide a better heat
conduction. You can obtain
energy saving up to 1/3.
• Vessels and pots must be
compatible with the cooking
zones. Bottom of the vessels or
pots must not be smaller than
the hot plate.
• Keep the cooking zones and
bottom of the pots clean.
Dirt will increase the heat
conduction between the
cooking zones and the bottom
of the pot.
• For long cooking periods, turn
off the cooking zone 5 or 10
minutes before the end of
cooking time. You cab obtain
energy savings up to 20% by
using residual heat.
• NEVER fill the pan with oil
more than one third of it. Do not
leave the hob unattended with
oil. Overheated oil brings risk
of fire.
Never attempt to extinguish a
possible fire with water! When oil
catches fire, cover it with a fire
blanket or damp cloth. Turn off
the hob if it is safe to so and call
the fire department.
• Before frying foods, always
dry them well and gently place
into hot oil. Ensure complete
thawing of frozen foods
before frying.
• Do not cover the vessel you
are using when heating oil.
• Place pans and saucepans
in a manner so that their
handles are not over the hob
to prevent heating of handles.
Do not place unbalanced and
easily tilting vessels on the hob.
• Do not place empty vessels
and saucepans on cooking
zones that are switched on.
They might get damaged.
• Operating a cooking zone
without a vessel or saucepan
on it will cause damage to
the product.
Turn off the cooking zones after
the cooking is complete.
4. Information about cooking

10 www.howdens.com
4-Zone Ceramic Hob LAM1746
• As the surface of the product
can be hot, do not put plastic
and aluminium vessels on it.
Clean any melted materials on
the surface immediately. Such
vessels should not be used to
keep food either.
• Use flat bottomed saucepans
or vessels only.
• Put appropriate amount of
food in saucepans and pans.
Thus, you will not have to make
any unnecessary cleaning by
preventing the dishes from
over flowing.
• Do not put covers over the
saucepans or pans on the
cooking zones.
Place the saucepans in a
manner so that they are
centred on the cooking zone.
When you want to move the
pan onto another cooking zone,
lift and place it onto cooking
zone rather than sliding it.
Tips about glass ceramic hobs
• Glass ceramic surface is
heatproof and is not affected
by big temperature differences.
• Do not use the glass ceramic
surface as a place to store or
as a cutting board.
• Use only saucepans and pans
with machined bottoms. Sharp
edges create scratches on
the surface.
• Do not use aluminium
vessels and saucepans.
Aluminium damages the
glass ceramic surface.

Instructions and Installation
Sensor calibration
and error codes
When the supply power is
applied, hob control system
performs calibration depending
on the sensor, glass and ambient
conditions. Do not cover the
sensor with anything during
calibration. Hob control system
should also not be exposed to
strong light sources such as sun
light, strong halogen lamps etc.
Sample application:
• Following lighting conditions
will allow a smooth calibration:
• Illumination with a bulb without
a reflector (100W dull) 70cm
above the glass ceramic hob.
After a successful calibration,
it is warranted that the hob
will operate as intended even
under a strong illumination such
as halogen spot lamp
with reflector (50W).
• 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 the sensors
is successful.
• You must be remove all
substances on the hob during
calibration. Also the ambient
illumination should not be too
strong during calibration. If
one of the F1, F1, F3 messages
is obtained, user must turn off
all light sources or close the
window during the calibration
process at first connection
to the power supply. When
the calibration is completed
successfully, control system
can tolerate a high amount
of ambient light.
• Hob control system changes
in ambient conditions while it
is in use.
• Touch control is equipped
with a sensor ensuring
protection against overheating.
Relevant cooking zone will be
deactivated when reacting
to this sensor. To obtain more
information on error messages,
please see the table opposite.
• If a key is activated repeatedly
(for longer than 10 seconds),
all control system is deactivated
and an audio signal is given.

6. Cleaning and maintenance
How to clean your hob
• The ceramic hob top can
be cleaned using a clean,
damp cloth or kitchen paper.
Do not use a used dishcloth
or sponge as they can leave
a film of detergent on the
surface which can lead to
discolouration. Please ensure
that the elements are cooled
fully to avoid steam burns.
• You can use a specialist
ceramic cleaner to restore
the surface, but use sparingly
to avoid coating the hob
top too thickly. Too much
cream cleaner will lead to
discolouration. Use a dry, clean
cloth to polish the surface.
• For stubborn marks, a specialist
hob scraper can be used.
• Do not use steam cleaners
or high pressure cleaning
equipment.
• Regular cleaning will prevent
any salts or minerals from
accumulating on your hob
and discolouring the glass.
• Wipe any spillage as soon
as possible.
• Clean the hob top as regularly
as possible, this will prevent any
build up of grease which may
be a fire hazard.
• Foods with high sugar content
(toffee, fruit juice, jam, etc.)
that boil over while cooking,
or spattered sugar stains must
be immediately removed using
a scraper even if hot.
• Do not use abrasive products,
bleach, hob cleaner spray or
pan scourers.
