Electrical Requirements
Observe all governing codes and ordinances.
Required:
■ A 120 volt, 60 Hz, AC only, 15- or 20-amp electrical supply
with a fuse or circuit breaker.
Recommended:
■ A time-delay fuse or time-delay circuit breaker.
■ A separate circuit serving only this microwave oven.
Venting Requirements
This section is intended for architectural designer and
builder/contractor reference only.
NOTES:
■ If installing for recirculation, venting must be routed up and
out through an exhaust register (not provided) in a kitchen
soffit. A charcoal filter kit (not provided) should be used. See
“Assistance” section for information on ordering.
■ Vent materials needed for installation are not provided with
microwave hood combination.
■ We do not recommend using a flexible metal vent.
■ To avoid possible product damage, be sure to vent air
outside, unless using recirculation installation. Do not vent
exhaust air into concealed spaces, such as spaces within
walls or ceilings, attics, crawl spaces or garages.
For optimal venting installation, we recommend:
■ using roof or wall caps that have back draft dampers
■ using a rigid metal vent
■ using the most direct route by minimizing the length of the
vent and number of elbows to provide efficient performance
■ using uniformly sized vents
■ using duct tape to seal all joints in the vent system
■ using caulking compound to seal exterior wall or roof opening
around cap
■ for optimal hood performance, do not install 2 elbows
together
If rectangular to round transition is used, be sure there is at least
3" (7.6 cm) of clearance between the top of the damper assembly
and the transition piece. See “Rectangular to Round Transition”
illustration.
Electrical Shock Hazard
Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death,
fire, or electrical shock.
WARNING
GROUNDING INSTRUCTIONS
SAVE THESE INSTRUCTIONS
■ For all cord connected appliances:
The microwave oven must be grounded. In the event of
an electrical short circuit, grounding reduces the risk of
electric shock by providing an escape wire for the electric
current. The microwave oven is equipped with a cord
having a grounding wire with a grounding plug. The plug
must be plugged into an outlet that is properly installed
and grounded.
WARNING:
Improper use of the grounding plug can
result in a risk of electric shock. Consult a qualified
electrician or serviceman if the grounding instructions are
not completely understood, or if doubt exists as to whether
the microwave oven is properly grounded.
Do not use an extension cord. If the power supply cord is
too short, have a qualified electrician or serviceman install
an outlet near the microwave oven.
