DANGER

This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others.

All safety messages will follow the safety alert symbol and the word “DANGER”, “WARNING”, or “CAUTION”. These
words are defined as:

Indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNING

CAUTION

Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.

IMPORTANT SAFETY INSTRUCTIONS

A qualified electrician must perform a ground
continuity check on the wall receptacle before
beginning the installation to ensure that the
outlet box is properly grounded. If not properly
grounded, or if the wall receptacle does not meet
electrical requirements noted (under ELECTRICAL
REQUIREMENTS), a qualified electrician should be
employed to correct any deficiencies.

WARNING

shock hazard from this appliance.

Where a standard two-prong wall receptacle is
encountered, it must be replaced with a properly
grounded three-prong wall receptacle, installed
by a qualified electrician.

HOOD EXHAUST

NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to recirculate the air back
into the room, proceed to page 11.

Total Length = 41 Ft.

* IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper

will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

NOTE: For back exhaust, care should be taken to align exhaust with space between studs, or wall
should be prepared at the time it is constructed by leaving enough space between the wall studs to
accommodate exhaust.

Installation Instructions

NOTE: If you need to install ducts, note that the total

duct length of 31⁄4″x10″rectangularor6″diameterround
duct should not exceed 140 equivalent feet.

Outside ventilation requires a HOOD EXHAUST DUCT.
Read the following carefully.

NOTE: It is important that venting be installed using
the most direct route and with as few elbows as possible.
This ensures clear venting of exhaust and helps prevent
blockages. Also, make sure dampers swing freely and

nothing is blocking the ducts.

Exhaust connection:

The hood exhaust has been designed to mate with
a standard 31⁄4″x10″rectangularduct.

If a round duct is required, a rectangular-to-round
transition adaptor must be used. Do not use less than

a 6″ diameter duct.

not exceed 140 equivalent feet.

Elbows, transitions, wall and roof caps,
etc., present additional resistance to airflow 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 length of all straight duct sections.
The chart below shows you how to calculate total
equivalent ductwork length using the approximate feet of
equivalent length of some typical ducts.

• If the space between the cabinets is greater than

30”, a Filler Panel Kit may be used to fill in the gap
between the microwave oven and the cabinets. Your
Owner’s Manual contains the kit number for your
model.

• If you are going to vent your oven to the outside, see

Hood Exhaust Section for exhaust duct preparation.

• When installing the oven beneath smooth, flat

cabinets, be careful to follow the instructions on the
top cabinet template for power cord clearance.

• * 13” max: for standard installation, 15” cabinet
depth requires additional steps using an additional
installation kit JX15BUMPWW/BB.

• For models with top venting holes: Do not allow

cabinetry or other objects to block the airflow of the vent.

• Café branded over-the-range microwaves should only

be installed over Café branded ranges. Installation over
any other range may result in surface temperatures that
can cause burns.

• All other over-the-range microwaves should not be

installed over any cooktop or range with a combined
BTU greater than 60,000 BTU.

1

Find the studs, using one of the following

methods:

A. Stud finder – a magnetic device which

locates nails.

OR

B. Use a hammer to tap lightly across the

mounting surface to find a solid sound.
This will indicate a stud location.

After locating the stud(s), find the center by

2

probing the wall with a small nail to find the edges
of the stud. Then place a mark halfway between
the edges. The center of any adjacent studs

shouldbe16″or24″fromthismark.

3

Draw a line down the center of the studs.

THE MICROWAVE MUST BE CONNECTED TO
AT LEAST ONE WALL STUD.

Draw a vertical line on the wall at the center of the
30” wide space. Tape the Rear Wall Template onto
the wall matching the centerline and touching the
bottom of the cabinet

Plate Position – beneath framed
recessed cabinet bottom

30” to Cooktop

Draw a vertical line on the wall at the center of the
30” space.
Tape the Rear Wall Template onto the wall
matching the centerline and touching the bottom
cabinet frame.

Your cabinets may have decorative trim that interferes
with the microwave installation. Remove the decorative
trim to install the microwave properly and to make it
level.

THE MICROWAVE MUST BE LEVEL

Use a level to make sure the cabinet bottom is level.
If the cabinets have a front overhang only, with no

back or side frame, install the mounting plate down the
same distance as the front overhang depth. This will
keep the microwave level.

1

Measure the inside depth of the front overhang.
Draw a horizontal line on the back wall an equal

2

distance below the cabinet bottom as the inside
depth of the front overhang.

For this type of installation with front overhang only,

3

align the Rearwall Template with this horizontal
line, not touching the cabinet bottom as described
in Step D.
