becoming entangled in or tripping over a longer cord.
b) Longer cord sets or extension cords are available and may be used if
care is exercised in their use.
c) If a long cord or extension cord is used:
1) The marked electrical rating of the cord set or extension cord should
be at least as great as the electrical rating of the appliance.
2) The extension cord must be a grounding type 3-wire cord, and
3) The longer cord should be arranged so that it will not drape over the
counter top or tabletop where it can be pulled on by children or
tripped over unintentionally.
This over-the-range oven was designed for use over ranges no wider
than 30inches. It may be installed over both gas and electric cooking
equipment.
Grounding Instructions
This appliance must be grounded. In the event of an electrical short circuit,
grounding reduces the risk of the electric shock by providing an escape
wire for the electric current. This appliance 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 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
appliance is properly grounded, and either:
1) If it is necessary to use an extension cord, use only a 3-wire extension
cord that has a 3-blade grounding plug, and a 3-slot receptacle that will
accept the plutg on the
appliance. The marked rating of
the extension cord shall be equal
to or greater than the electrical
rating of the appliance, or Do not
use an extension cord.
2) If the power supply cord is too
short, have a qualified
electrician or serviceman
install an outlet near the
appliance.

Wall Construction
Your Over-the-Range microwave oven should be mounted against and supported by a flat, vertical wall. Wall construction should be
a minimum of 2” x 4” wall studding and 3/8” or more, thick drywall or plaster/lath. The oven must be attached to a minimum of one
2” x 4” wall stud.
For proper installation the wall must be capable of supporting the cabinet load plus a minimum of 135 pounds, (the 85 pound weight
of the microwave oven and load weight allowance of 50 pounds.) To find studs, use one of the following methods:
I. Stud finder a magnetic device which locates nails.
II. Using a hammer, tap lightly across the mounting surface
to find a solid sound. This will indicate a stud
installation. After locating the stud(s), the center can be
found by: Probing the wall with a small nail to find the
edges of the stud and then placing a mark half way
between the edges. The center of any adjacent studs
should be 16” or 24” from this mark.
Outside ventilation requires HOOD
EXHAUST DUCT. Read the following
carefully.
EXHAUST CONNECTION: The hood
exhaust has been designed to mate with a
standard 3-1/4” x 10” rectangular duct.
If round duct is required, a rectangular-toround transition adapter must be used. Do not
use less than a 6” diameter duct.
REAR EXHAUST: If rear or horizontal
exhaust is to be used, care should be taken to
align exhaust with space between studs, or wall
should be prepared at the time it is comstructed
by leaving enough space between wall studs to
accommodate exhaust.
MAXIMUM DUCT LENGTH: For
satisfactory air movement, the total duct length
of 3-1/4” x 10” rectangular or 6” diameter
round duct should not exceed 140 feet of
epuivalent duct run.
ELBOWS, TRANSITIONS, WALL AND
ROOF CAPS, etc.,
present additional resistance to air flow and are
equivalent to a section of straight duct which is
longer than their actual physical size. When
calculating the total duct length add the
equivalent lengths of all transitions and
adaptors plus the lengths of all straight duct
sections. The diagram below shows the
approximate feet of equivalent length of some
typical ducts.
