Failure to follow this procedure may result in fire and
oven damage.
Ensure there is a minimum of free space above the
oven of 25 cm.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory or
mental capabilities, or lack of experience and
knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do
not play with the appliance.
WARNING: Only allow children to use the oven without
supervision when adequate instructions have been
given so that the child is able to use the oven in a safe
way and understands the hazards of improper use.
WARNING: If the door or door seals are damaged,
the oven must not be operated until it has been
repaired by a competent person.
WARNING: Never adjust, repair or modify the oven
yourself. It is hazardous for anyone other than a
competent person to carry out any service or repair
operation which involves the removal of a cover which
gives protection against exposure to microwave
energy.
If the power supply cord of this appliance is damaged,
it must be replaced by an authorised SHARP service
agent in order to avoid a hazard.
WARNING: Liquids and other foods must not be
heated in sealed containers since they are liable to
explode.
WARNING: Microwave heating of beverages can
result in delayed eruptive boiling, therefore care must
be taken when handling the container.
Do not cook eggs in their shells, and whole hard boiled
eggs should not be heated in microwave ovens since
they may explode even after microwave cooking has
ended. To cook or reheat eggs which have not been
scrambled or mixed, pierce the yolks and the whites,
or the eggs may explode. Shell and slice hard boiled
eggs before reheating them in the microwave oven.
Utensils should be checked to ensure that they are
suitable for use in the oven. See page 14. Use only
microwave safe containers and utensils on microwave
modes.
WARNING: The contents of feeding bottles and baby
food jars must be stirred or shaken and the temperature
checked before consumption, in order to avoid burns.
When heating food in plastic or paper containers, keep
an eye on the oven due to the possibility of ignition.
Clean the oven at regular intervals and remove any food
deposits.
Failure to maintain the oven in a clean condition could
lead to deterioration of the surface that could adversely
affect the life of the appliance and possibly result in a
hazardous situation.
See instructions for cleaning door seals, cavities and
adjacent parts on page 28.
The oven should not be cleaned with a water jet.
Use oven gloves when removing food from the oven
to prevent burns.
The microwave oven should not be left unattended during
operation. Power levels that are too high, or cooking times
that are too long, may overheat foods resulting in a fire.
A separate circuit serving only this appliance should be
provided.
Oven Use:
• The oven is for food preparation only.
Never operate when empty.
• Do not leave or store anything inside the oven when
not in use.
• Never attempt to use the oven with the door open.
It is important not to tamper with the door safety latches.
This may result in exposure to microwave energy.
• Never operate the oven with any object caught in
the door sealing surfaces, this again may cause
microwave leakage.
• Do not insert fingers or objects in the holes of the
door latches or air vent openings as this may
damage the oven and cause an electric shock.
• If water or food drops inside the air vent openings
switch off the oven immediately, unplug it and call a
Service Technician appointed by SHARP.
• Never attempt to move the oven while it is operating.
• Do not use the oven near a steamer or a fryer.
• Always wipe up spills on the ceramic floor and splashes
on the walls after cooking. If you leave grease on the
ceramic floor and walls it may overheat, smoke or even
catch fire when next using your oven.

WARNING:
!
Inspect the Oven:
Check the oven carefully for damage before and
regularly after installation.
•Make sure the door closes properly, that it is not
misaligned or warped.
•Check the hinges and door safety latches are
not broken or loose.
• Ensure the door seal and sealing surfaces are
not damaged.
• Inspect the oven interior and door for dents.
Caution Sheet:
Always keep the caution sheet (Special Instructions
and Warnings) close to the oven for your reference.
Important:
If any damage is apparent, do not operate the oven
in any way. Contact your dealer or an authorised
Service Technician appointed by SHARP.
1
Remove all packing materials. Remove the protective
film (blue film) from the outer case cabinet (if covered).
Do not remove the plastic film from the inside of the
oven window as this protects it from dirt.
2
Place oven on a secure, level surface, strong enough
to take the oven weight, plus the heaviest item likely
to be cooked in the oven.
Do not place this oven in a position which is not easily
accessible. To position the oven too high can be
dangerous because food can not be removed safely.
3 Ensure there is a minimum free space above the
oven of 25 cm.
4 Do not place the oven where heat, moisture or high
humidity are generated, (for example, near or above
a conventional oven) or near combustible materials
(for example, curtains). Do not block or obstruct air
vent openings, as obstructions may ignite due to
the emission of hot air.
5
Make sure the power supply cord is undamaged and
that it does not run under the oven or over any hot or
sharp surfaces.
6 The socket must be readily accessible so that it can
be easily unplugged in an emergency.

BUILDING-IN-KIT
This oven is not designed to be built into a kitchen unit.
IMPORTANT! ELECTRICAL CONNECTION
• Do not allow water to come into contact with the
power supply cord or plug.
• Insert the plug properly into the socket as the plug
may otherwise overheat and catch fire.
• Do not connect other appliances to the same socket
using an adaptor plug as it may cause the wiring to
overheat and catch fire.
• If the plug or socket is loose or the power supply
cord is damaged, do not operate the oven, it must be
replaced by the special power cord. Contact your
dealer or a Service Technician appointed by SHARP.
A defective plug, power supply cord or socket may overheat
and catch fire during operation or cause an electrical shock.
•
When removing the plug from the socket always grip
the plug, never the mains lead as this may damage the
power supply cord and the connections inside the plug.
• The product is fitted with a non-rewireable (moulded)
plug. Should it not be suitable for the socket outlet in
your kitchen, remove the plug and fit an appropriate
type, observing the wiring code given in "To replace
the mains plug" on page 30.
The fuse from a cut-off plug should be removed and the
plug disposed of in safe manner. Under no circumstances
should the cut-off plug be inserted into a socket outlet as
serious electrical shock may occur. The plug must not be
used without the fuse cover fitted.
When replacing the plug please ensure that you use a BSI
or ASTA approved plug to BS1363, this should be fitted
with a brown coloured 13 amp fuse approved by BSI or
ASTA to BS1362. If you have any doubt about electrical
connection seek the help of a qualified electrician.
WARNING
!
THIS APPLIANCE MUST BE EARTHED.
