IMPORTANT SAFETY INSTRUCTIONS
When using electrical appliances basic safety precautions should be followed, including the following:
WARNING: To reduce the risk of burns, electric
shock, fire, injury to persons, or exposure to excessive
microwave energy:
■ Read all instructions before using the microwave oven.
■ Read and follow the specific “PRECAUTIONS TO
AVOID POSSIBLE EXPOSURE TO EXCESSIVE
MICROWAVE ENERGY” found in this section.
■ The microwave oven must be grounded. Connect only
to properly grounded outlet. See “GROUNDING
INSTRUCTIONS” found in this section and in the
provided Installation Instructions.
■ Install or locate the microwave oven only in
accordance with the provided Installation Instructions.
■ Some products such as whole eggs in the shell and
sealed containers – for example, closed glass jars –
are able to explode and should not be heated in the
microwave oven.
■ Use the microwave oven only for its intended use as
described in this manual. Do not use corrosive
chemicals or vapors in the microwave oven. This type
of oven is specifically designed to heat, cook, or dry
food. It is not designed for industrial or laboratory use.
■ As with any appliance, close supervision is necessary
when used by children.
■ Do not operate the microwave oven if it has a
damaged cord or plug, if it is not working properly, or
if it has been damaged or dropped.
■ The microwave oven should be serviced only by
qualified service personnel. Call an authorized service
company for examination, repair, or adjustment.
■ See door surface cleaning instructions in the
“Microwave Oven Care” section.
■ To reduce the risk of fire in the oven cavity:
– Do not overcook food. Carefully attend the microwave oven
when paper, plastic, or other combustible materials are placed
inside the oven to facilitate cooking.
– Remove wire twist-ties from paper or plastic bags before
placing bags in oven.
– If materials inside the oven ignite, keep oven door closed, turn
oven off, and disconnect the power cord, or shut off power at
the fuse or circuit breaker panel.
– Do not use the cavity for storage purposes. Do not leave
paper products, cooking utensils, or food in the cavity when
not in use.
■ Liquids, such as water, coffee, or tea are able to be overheated
beyond the boiling point without appearing to be boiling. Visible
bubbling or boiling when the container is removed from the
microwave oven is not always present. THIS COULD RESULT
IN VERY HOT LIQUIDS SUDDENLY BOILING OVER WHEN
THE CONTAINER IS DISTURBED OR A SPOON OR OTHER
UTENSIL IS INSERTED INTO THE LIQUID.
To reduce the risk of injury to persons:
– Do not overheat the liquid.
– Stir the liquid both before and halfway through heating it.
– Do not use straight-sided containers with narrow necks.
– After heating, allow the container to stand in the microwave
oven for a short time before removing the container.
– Use extreme care when inserting a spoon or other utensil into
the container.
■ Oversized foods or oversized metal utensils should not be
inserted in the microwave oven as they may create a fire or risk
of electric shock.
■ Do not clean with metal scouring pads. Pieces can burn off the
pad and touch electrical parts involving a risk of electric shock.
SAVE THESE INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
■ Do not operate any heating or cooking appliance beneath the
microwave oven.
■ Do not mount microwave oven over or near any portion of a
heating or cooking appliance.
■ Do not use paper products when appliance is operated in the
“PAN BROWN” mode (on models with this feature).
■ Do not store any materials, other than manufacturer’s
recommended accessories, in this microwave oven when not
in use.
■ Do not store anything directly on top of the microwave oven
when the microwave oven is in operation.
■ Do not cover or block any openings on the microwave oven.
SAVE THESE INSTRUCTIONS
■ Do not store this microwave oven outdoors. Do not use
the microwave oven near water - for example, near a
kitchen sink, in a wet basement, or near a swimming
pool, or similar locations.
■ Do not immerse cord or plug in water.
■ Keep cord away from heated surfaces.
■ Do not let cord hang over edge of table or counter.
■ Do not mount over a sink.
■ Do not cover racks or any other part of the microwave
oven with metal foil. This will cause overheating of the
microwave oven.

PRECAUTIONS TO AVOID POSSIBLE EXPOSURE TO
EXCESSIVE MICROWAVE ENERGY
(a) Do not attempt to operate this oven with the door open
since open-door operation can result in harmful exposure
to microwave energy. It is important not to defeat or
tamper with the safety interlocks.
(b) Do not place any object between the oven front face and
the door or allow soil or cleaner residue to accumulate on
sealing surfaces.
This device complies with Part 18 of the FCC Rules.
(c) Do not operate the oven if it is damaged. It is particularly
important that the oven door close properly and that there
is no damage to the:
(1) Door (bent),
(2) Hinges and latches (broken or loosened),
(3) Door seals and sealing surfaces.
(d) The oven should not be adjusted or repaired by anyone
except properly qualified service personnel.
INSTALLATION INSTRUCTIONS
Unpacking
1. Empty the microwave oven of any packing materials.
2. Clean the inside with a soft, damp cloth.
3. Check for damage, such as:
■ a door that is not lined up correctly
■ damage around the door, or
■ dents on the interior or exterior of the microwave oven.
If there is any damage, do not operate the microwave oven
until a designated service technician has checked it and
made any needed repairs.
Location Requirements
WARNING
Fire Hazard
Do not install oven next to or over a heat source
without a UL listed (CSA approved in Canada)
trim kit.
Doing so can result in death, fire, or electrical shock.
WARNING
Excessive Weight Hazard
Use two or more people to move and install
microwave oven.
Failure to do so can result in back or other injury.
IMPORTANT: The control side of the microwave oven is the
heavy side. Handle the microwave oven gently. The weight of the
microwave oven is 43 lbs (19.5 kg).
■ Place the microwave oven on a cart, counter, table or shelf
that is strong enough to hold the microwave oven and the
food and utensils you place inside it.
■ The microwave oven should be at a temperature above 50°F
(10°C) for proper operation.
NOTE: Some models can be built into a wall or cabinet by using
one of the trim kits listed in the “Assistance or Service” section.
