lnstalla tion Instructions
(RJM 740)
First: Take everything out of the oven. Wipe out the inside with a damp
cloth.
Second: Put the microwave oven on a counter, cart, table or shelf
which has enough strength to hold it. For ventilation, leave two inches
between the back of the oven and the wall. Do not block the vents on
top. They are needed for air flow and even cooking.
This oven can be built into a wall or cabinet. Kits RCK703 and RCK707
are available from your dealer for recessed installation. It can also be
installed, with those kits, above Whirlpool RDE, REE and RGE series
single ovens, or Hardwick 7200 single gas ovens. Follow the manufacturer’s installation instructions. The RCK710, RCK711, and RCK713 can
be used for surface mounting on a wall. The MICRO SHELF* Hood,
Model RJH3330, is available for mounting the microwave oven above a
range or cooktop.
Third: For your safety, this oven must be grounded. Its cord has the
3-prong grounding plug. DO NOT CUT THE ROUND GROUNDING
PRONG FROM THE PLUG. If the wall receptacle doesn’t have the right
plug-in, or if the plug-in isn’t grounded according to the National
Electrical Code and local codes or ordinances, you must have a
qualified electrician put in the right outlet.
Fourth: The outlet must supply 120 volts, 60 Hz., A.C. The microwave
oven will use about 1450 watts when it is operating, so no other major
household appliance should share the circuit.
Fifth: Fill a glass container with about one cup (250 mL) of cold water
and put it in the oven. Turn the oven on full power for 1 to
(see page 7). When the time is up, the water should be heated.
Sixth: If the microwave oven has been stored in a cool room, the fan
may run slower than usual until the oven warms up to room
temperature.

MICROWAVE BASICS

WAVEGUIDE
MAGNETRON
How a Microwave Oven Works
Microwaves are like radio waves or radar waves. They will pass through
glass, plastic, paper and most other types of containers that are not
metal. Microwaves bounce off metal and are absorbed by food. When
food absorbs microwaves, heat is created because water molecules in
the food are disturbed and bounce around colliding with each other.
Heat is created by this bouncing and colliding. like when you warm
your hands by rubbing them together.
When all safety systems are secure (door shut completely and the
START button pushed), electric current is allowed to reach the
magnetron tube. The magnetron tube uses electricity to create
microwaves. They pass through a metal tunnel called the waveguide,
past the wave tuner, into the oven cavity.
Just at the point where the microwaves are about to go into the oven
cavity, Whirlpool Microwave Ovens use a mode mixer (a slow-moving
metal fan) to scatter them. If all the microwaves went in the same
