1. Precaution
1-3 Important Safety Instructions
Read and follow all instructions before using your oven to prevent the risk of fire, electric shock, injury to person,
or damage when using the range. This guide don’t cover all possible conditions that may occur. For further
assistance contact your service agent or manufacturer.
WARNING
This symbol will help alert you to hazards or unsafe practices which could cause serious bodily harm or death.
•B
e sure your appliance is properly installed and
grounded by a qualified technician.
• Do not repair or replace any part of the appliance unless
specifically recommended in the manual. All other
servicing should be referred to a qualified technician.
• Always disconnect power to appliance before servicing
by removing the fuse or switching off the circuit breaker
CAUTION
Do not store items of interest to children in
cabinets above a range or on the back guard of
a range – children climbing on the range to reach
items could be seriously injured.
• Do Not Leave Children Alone - Children should not be left
alone or unattended in area where appliance is in use.
They should never be allowed to sit or stand on any part
of the appliance.
• Never Use Your Appliance for Warming or Heating the Room.
• Storage in or on Appliance – Flammable materials should
not be stored in an oven or near surface units. Be sure all
packing materials are removed from the appliance before
operating it. Keep plastics, clothes and paper away from
parts of the appliance that may become hot
• Wear Proper Apparel – Loose-fitting or hanging garments
should never be worn while using the appliance.
• Do Not Use Water on Grease Fires – Turn off oven to
avoid spreading the flame. Smother the fire or flame by
closing the door or use dry chemical, baking soda or
foam- type extinguisher.
• Use Only Dry Potholders – Moist or damp potholders on
hot surfaces may result in burns from steam. Do not let
potholder touch hot heating elements. Do not use a towel
or other bulky cloth.
WARNING
- INJURIES CAN OCCUR IF THE RANGE TIPS
- INSTALL ANTI-TIP DEVICE PACKED WITH

-F
OLLOW ALL INSTALLATION
INSTRUCTIONS
To reduce the risk of tipping of the range, the range
must be secured by properly installed anti-tip devices.
To check if the bracket is installed properly,
- Warming drawer : grasp the top rear edge of the
Range and carefully attempt to tilt it forward.
verify that the anti-tip devices are engaged.
- Storage drawer : Remove drawer and verify leveling
leg is inserted into and fully secured by the anti-tip
devices.
Refer to the installation manual for proper anti-tip
bracket installation.
• Do not step, lean or sit on the doors of the range
-this can cause the range to tip, resulting in burns or
serious injuries.
WARNING
SURFACES
• DO NOT TOUCH SURFACE UNITS OR AREAS NEAR
UNITS – Surface units may be hot even though they
are dark in color. Areas near surface units may become
hot enough to cause burns. During and after use, do not
touch, or let clothing or other flammable materials contact
surface units or areas near units until they have had
sufficient time to cool. Among these areas are the cooktop and surfaces close to the cook-top.
WARNING
• DO NOT TOUCH HEATING ELEMENTS OR
INTERIOR SURFACES OF OVEN – Heating
elements may be hot even though they are dark
in color. Interior surfaces of an oven become hot
enough to cause burns. During and after use,
do not touch, or let clothing or other flammable
materials contact heating elements or interior
surfaces of oven until they have had sufficient
time to cool. Other surfaces of the appliance may
become hot enough to cause burns – among
these surfaces are oven vent openings and
surfaces near these openings, oven doors, and
windows of oven doors.
WARNING
To avoid risk of electrical shock, personal injury, or
death, make sure your range has been properly
grounded and always disconnect it from main power
supply before any servicing.

1. Precaution
SURFACE COOKING UNITS
VENTILATING HOODS:
• Use Proper Pan Size – This appliance is equipped
with one or more surface units of different sizes.
Select utensils having flat bottoms large enough
to cover the surface unit heating element. The use
of undersized utensils will expose a portion of the
heating element to direct contact and may result in
ignition of clothing. Proper relationship of utensil to
burner will also improve efficiency.
• Never Leave Surface Units Unattended at High
Heat Settings – Boil overs may cause smoking and
greasy spillovers may ignite.
• Make Sure Reflector Pans or Drip Bowls
Are in Place – Absence of these pans or bowls
during cooking may subject wiring or components
underneath to damage.
•P
rotective Liners – Do not use aluminum foil to line
surface unit drip bowls or oven bottoms, except as
suggested in the manual. Improper installation of these
liners may result in a risk of electric shock, or fire.
• Glazed Cooking Utensils – Only certain types of
glass, glass/ceramic, ceramic, earthenware, or other
glazed utensils are suitable for range-top service
without breaking due to the sudden change in
temperature.
• Utensil Handles Should Be Turned Inward and
Not Extend Over Adjacent Surface Units – To
reduce the risk of burns, ignition of flammable
materials, and spillage due to unintentional contact
with the utensil, the handle of a utensil should be
positioned so that it is turned inward, and does not
extend over adjacent surface units.
• Do Not Soak Removable Heating Elements –
Heating elements should never be immersed in water.
• Be sure you know which control pads operate each
surface unit. Make sure you turned on the correct
surface unit.
• Clean Ventilating Hoods Frequently – Grease
should not be allowed to accumulate on hood or filter.
• When flaming foods under the hood, turn the fan on.
OVEN
• Use Care When Opening Door – Let hot air or
steam escape before you remove or replace food in
the oven
• Do Not Heat Unopened Food Containers – Buildup of pressure may cause container to burst and
result in injury.
• Keep Oven Vent Ducts Unobstructed – the oven
vent is located above the left rear surface unit. this
area could become hot during oven use. Never block
this vent and never place plastic or heatsensitive
items on vent
• Placement of Oven Racks – Always place oven
racks in desired location while oven is cool. If rack
must be moved while oven is hot, do not let potholder
contact hot heating element in oven.
• Do Not allow aluminum foil or meat probe to contact
heating elements.
GLASS/CERAMIC COOKING SURFACES
• Do Not Cook on Broken Cook-Top – If cook-top
should break, cleaning solutions and spillovers
may penetrate the broken cooktop and create a
risk of electric shock. Contact a qualified technician
immediately.
• Clean Cook-Top With Caution – If a wet sponge
or cloth is used to wipe spills on a hot cooking area,
be careful to avoid steam burn. Some cleaners can
produce noxious fumes if applied to a hot surface.
DEEP FAT FRYERS:
SELF-CLEAN OVENS
• Use extreme caution when moving the grease kettle
or disposing of hot grease.
• Do Not Clean Door Gasket – The door gasket is
essential for a good seal. Care should be taken not to
rub, damage, or move the gasket.
• Do Not Use Oven Cleaners – No commercial oven
cleaner or oven liner protective coating of any kind
should be used in or around any part of the oven.
• Clean in the self-clean cycle only parts listed in
this manual. Before self-cleaning the oven, remove
the broiler pan and any utensils from the oven.
• Never keep pet birds in the kitchen – the health
of birds is extremely sensitive to the fumes released
during an oven selfclean cycle. Fumes may be harmful
or fatal to birds. Move birds to well-ventilated room.
• Important Instruction – In the event the self-clean
mode “F” code goes on, or three long beeps sound,
oven is malfunctioning in the self-clean mode. Turn
off or disconnect appliance from power supply and
have serviced by a qualified technician.

Oven sensor Connector
Door plunger switch, cooktop warming center, oven lamp and relay of convection fan connector
This is connector which take a role of supplying secondary voltage of Low voltage transformer with main
PCB.
This is to supply power with primary on Low voltage transformer, and AC120V with main PCB through
harness. It won’t be problem even though CN08 and CN09 has been changed when you insert housing.
This is consisted of 15 pin and take a role of getting a cable on keypad to connect with touch PCB.
This connector is to get all operating of relay on sub PCB to be connected.
This is connector which is connected with oven sensor.
This is connector which is connected with Door plunger switch and Door lock switch. (COM-NO, COM-NC)
