automatic ice-making mechanism while the refrigerator is plugged in.

•When dispensing ice from the dispenser, do not use crystal ceramics.

•Do not touch the cold surfaces in the freezer compartment with wet or damp hands, when your
refrigerator is in operation.

•Do not put glass containers, glass bottles or beverage cans in the freezer.

•Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance.

•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 the use of the appliance by a person responsible for their safety.

•Do not refreeze frozen foods that have thawed completely. It may result in serious health issues.

•If you are throwing away your old refrigerator, make sure the CFC coolant is removed for proper
disposal by a qualified servicer. If you release CFC coolant, you may be fined or imprisoned in

READ ALL INSTRUCTIONS BEFORE USING THE APPLIANCE.

To reduce the risk of fire, electric shock, or personal injury when using your product, basic safety
precautions should be followed, including the following.

CAUTION

Installation

•The refrigerator must be properly installed in accordance with the Installer Instructions that were taped

to the front of the refrigerator.

•Be careful when you unpack and install the refrigerator. Immediately dispose of packing materials

(plastic) out of reach of children.

Use

•Close the doors carefully when children are around.

•Keep fingers out of pinch point areas; clearances between the doors and cabinets are necessarily

small. Be careful closing doors when children are in the area.

•If food is stacked or stored poorly on the shelves, it may fall and cause injury when the door is opened.

•Do not move refrigerator while the refrigerator is operating. A Compressor rattling noise may occur

as a result and will only stop when the compressor cycles off, or when the power to the unit is
turned off and back on again. (This is normal and will not impact on the performance or the life of the
compressor. The rattling will stop after the compressor comes to a rest.)

Maintenance

•Do not use strong detergents like wax or thinners for cleaning. Clean with a soft fabric.

•Wipe foreign objects (dust, water, etc) off the prongs of the power plug and contact areas before

connecting.

WARNING

•Use drinkable water for ice making.

WARNING

•Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction.

•Do not use mechanical devices or other means to accelerate the defrosting process, other than those

recommended by the manufacturer.

•Do not damage the refrigerant circuit.

•Do not use electrical appliances inside the food storage compartments of the appliance, unless they

are of the type recommended by the manufacturer.

•The refrigerant and insulation blowing gas used in the appliance require special disposal procedures.

When disposal, please consult with service agent or a similarly qualified person.

This appliance contains a small amount of isobutane refrigerant (R600a), natural gas with high
environmental compatibility, but it is also combustible. When transporting and installing the
appliance, care should be taken to ensure that no parts of the refrigerating circuit are damaged.
Refrigerant squirting out of the pipes could ignite or cause an eye injury. If a leak is detected,
avoid any naked flames or potential sources of ignition and air the room in which the appliance is
standing for several minutes.

In order to avoid the creation of a flammable gas air mixture if a leak in the refrigerating circuit
occurs, the size of the room in which the appliance may be sited depends on the amount of
refrigerant used. The room must be 1m2 in size for every 8g of R600a refrigerant inside the
appliance. The amount of refrigerant in your particular appliance is shown on the identification
plate inside the appliance. Never start up an appliance showing any signs of damage. If in doubt,
consult your dealer.

Unpacking Your Refrigerator

WARNING

•Use two or more people to move and
install the refrigerator. Failure to do so
can result in back or other injury.

•Your refrigerator is heavy. When moving
the refrigerator for cleaning or service,
be sure to protect the floor. Always pull
the refrigerator straight out when moving
it. Do not wiggle or walk the refrigerator
when trying to move it, as floor damage
could occur. Wind the leveling feet up
first so that the unit is on its rollers.

•Keep flammable materials and vapors,
such as gasoline, away from the
refrigerator. Failure to do so can result in
fire, explosion, or death.

Remove tape and any temporary labels from
your refrigerator before using. Do not remove
any warning-type labels, the model and serial
number label, or the Tech Sheet that is located
under the front of the refrigerator.

To remove any remaining tape or glue, rub the
area briskly with your thumb. Tape or glue
residue can also be easily removed by rubbing
a small amount of liquid dish soap over the
adhesive with your fingers. Wipe with warm
water and dry.

Do not use sharp instruments, rubbing alcohol,
flammable fluids, or abrasive cleaners to
remove tape or glue. These products can
damage the surface of your refrigerator.

Refrigerator shelves are installed in the
shipping position. Please reinstall shelves
according to your individual storage needs.

Choosing the Proper Location

•The refrigerator should always be plugged
into its own individual properly grounded
electrical outlet rated for 220 Volts, 60 Hz,
AC only, and fused at 15 or 20 amperes.
This provides the best performance and
also prevents overloading house wiring
circuits which could cause a fire hazard
from overheated wires. It is recommended
that a separate circuit serving only this
appliance be provided.

WARNING

To reduce the risk of electric shock, do
not install the refrigerator in a wet or
damp area. do not install in any outdoor
or sheltered outdoor location or direct
sunlight.

Flooring

To avoid noise and vibration, the unit must be
leveled and installed on a solidly constructed
floor. If required, adjust the leveling legs to
compensate for unevenness of the floor. The
front should be slightly higher than the rear to
aid in door closing. Leveling legs can be turned
easily by tipping the cabinet slightly. Turn the
leveling legs to the left to raise the unit or to
the right to lower it. Poorly constructed timber
flooring can cause a limit in door adjustment
and the cabinet to become out of shape. (See
Leveling and door AlIgnment.)

NOTE

Installing on carpeting, soft tile surfaces,
a platform or weakly supported
structure is not recommended.

Exterior

Waxing external painted metal surfaces helps
provide rust protection. Do not wax plastic
parts. Wax painted metal surfaces at least
twice a year using appliance wax (or auto paste
wax). Apply wax with a clean, soft cloth.

For products with a stainless steel exterior,
use a clean sponge or soft cloth and a mild
detergent in warm water. Do not use abrasive
or harsh cleaners. Dry thoroughly with a soft
cloth.

WARNING

Use non-flammable cleaner. Failure to do
so can result in fire, explosion, or death.
Always remove power cord from the wall
outlet prior to cleaning in the vicinity of
electrical parts (lamps, switches, covers,
controls, etc.).

Wipe up excess moisture with a sponge or
cloth to prevent water or Liquid from
getting into any electrical part and causing
an electric shock.

Never use metallic scouring pads, brushes,
coarse abrasive cleaners, Strong alkaline
solutions, industrial detergent (bleach
containing detergent) Flammable or toxic
cleaning liquids on any surface. Do not use
Hot water to clean the interior or any
interior parts of the unit when they are
cold.

CAUTION

•Do not use a rough cloth or sponge
when cleaning the interior and exterior
of the refrigerator.

•Do not place your hand on the bottom
surface of the refrigerator when opening

Inside Walls (allow freezer to warm
up so the cloth will not stick)

To help remove odors, you can wash the inside
of the refrigerator with a mixture of baking
soda and warm water. Mix 2 tablespoons of
baking soda to 1 litre of warm water. Be sure
the baking soda is completely dissolved so it
does not scratch the surfaces of the
refrigerator.

Door Liners and Gaskets

Use a clean sponge or soft cloth and a mild
detergent in warm water. Do not use cleaning
waxes, concentrated detergents, bleaches, or
cleaners containing petroleum on plastic
refrigerator parts.

Plastic Parts (covers and panels)

Use a clean sponge or soft cloth and a mild
detergent in warm water. Do not use window
sprays, abrasive cleansers, or flammable fluids.
These can scratch or damage the material.

Condenser Coil Cover

Use a vacuum cleaner with an attachment to
clean the condenser cover and vents located at
the rear of the appliance. Do not remove the
panel covering the condenser coil area. Always
disconnect the main power before cleaning.
