supply
(located
in the upper cabinet
as
close as possible to the microwave
oven) is required.
Time-delay

For your personal
safety, this appli-
-ante
must be grounded.
This appli-
ance is equipped
with a power supply
cord having
a 3-prong
9
rounding
plug. to minimize
possrb e 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.
See
Figure 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.

Venting
requirements
Ductwork needed for installatton is
not included.
Wall and roof caps
used must have back-draft damper.
Fire Hazard
l
Venting system must terminate
to the outside.
l
Do Not terminate the ductwork
in an attic or other enclqsed
space.
l
Do Not use 4" laundry-type
wall caps.
l
Do Not use plastic or flexible
plastic ductwork.
Failure to Mow
recommended
venting procedures may result
in a fire.
-J
igid 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.
Some models cannot
be Installed
using the ventless (recirculating)
method.
The
length
of the ductwork
and
number
of elbows should be kept to
a mlnlmum
to provide
efflclent
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 ihat there is proper
clearance
within the'wall
for the
ductwork,

duct len
Use 3- l/4' x 10' or 6" duct. T i!
th
e 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"
rectan
ular or 6" diameter
round duct.
For bes performance,
use no more
7
than three 90" elbows. To calculate
the length
of system you need, add
the equivalent
feet for each duct
piece used in the system. See the

to
prevent
sticking of the exhaust
