Electrical Shock Hazard
wElectrical ground is required on
this appliance.
n Improper connection of
the equipment-grounding
conductor can result in
electrical shock.
n Check with a qualified elect&
cian if you are in doubt as to
whether the appliance is
properly grounded.
n Do Not use au extension cord
with this appliance.
Such use may result in a fire,
electrical shock or other personal
iujury.
n Do Not have a fuse in the
neutral or grounding circuit. A
fuse in the neutral or grounding
circuit could result in electrical
shock.
Failure to follow these instruc-
tions could result in electricaI
shock or other personal injury.
Instructions for local electrical
A 120-volt, 60-Hz, AC only, 15- or
20-ampere, fused electrical supply
(located in the upper cabinet as close as
possible to the microwave oven) is
required. Time-delay fuse or circuit
breaker is recommended. It
is recommended that a separate circuit
serving only this appliance
be orovided.
Recommended
grounding method
Do Not, under any circumstances,
remove the power supply cord
grounding prong.
For your personal safety, this appliance
must be grounded. This appliance is
equipped with a power supply cord
having a 3-prong grounding plug. To
minimize possible shock hazard, the
cord must be plugged into a mating
3-prong grounding-type wall receptacle,
grounded in accordance with the
National Electrical Code, ANWNFPA
70-latest edition* and all local codes
and ordinances. SeeFigure 1.If a
mating wall receptacle is not available,
it is the personal responsibility and
obligation of the customer to have
a properly grounded, 3-prong wall
receptacle installed by a qualified
electrician.

Ductwork needed for installation is
not included. Wall and roof caps used
must have back-draft damper.
Fire Hazard
. Venting system must terminate
to the outside.
n Do Not terminate the ductwork
in an attic or other enclosed
space.
. Do Not use 4” laundry-type
wall caps.
n Do Not use plastic or flexible
plastic ductwork.
Failure to follow recommended
venting procedures may result
in a fire.
Rigid metal ductwork is
recommended. Flexible ductwork is
Not recommended. If flexible metal
ductwork is used, calculate each foot of
flexible ductwork as two feet of straight
metal ductwork. Flexible elbows count
twice as much as standard elbows.
Determine which venting method
(roof-venting, wall-venting or ventless)
you need to use. This microwave oven
is equipped for roof- or wall-venting
installation. Somemodels cannot be
installed using the ventless
(recirculating) method.
The length of the ductwork and number
of elbows should be kept to a minimum
to provide efficient performance. The
size of ductwork should be uniform. Do
Not install two elbows together. Use
duct tape to seal all joints in the duct
system. Use caulking to seal exterior
wall or roof opening around cap.
Figures 2-5 show common venting
methods and types of materials needed.
Note: If the rear exhaust method is
chosen, be sure that there is proper
clearance within the wall for the
ductwork.

Recommended duct length
Use 3-l/4” x 10”or 6” duct. The total
length of the duct system including
straight duct, elbows, transitions, wall
or roof caps must not exceed the
equivalent of 140 feet of 3-l/4” x 10”
rectangular or 6” diameter round duct.
For best performance, use no more than
three 90” elbows. To calculate the
length of system you need, add the
equivalent feet for each duct piece
used in the system. Seethe following
