Introduction
Congratulations on your purchase of a high-quality Insignia product. Your NS-OTR16SS9 / NS-OTR16WH9 represents the
state of the art in microwave design and is designed for reliable and trouble-free performance.
This installation guide will show you how to install your new over-the-range microwave.
BEFORE YOU BEGIN
Read these instructions completely and carefully.
• IMPORTANT – Save these instructions for local inspector’s use.
• IMPORTANT – Observe all governing codes and ordinances.
• Note to Installer – Be sure to leave these instructions with the consumer.
• Note to Consumer – Keep these instructions for future reference.
• Skill level – Installation of this appliance requires basic mechanical and electrical skills.
• Proper installation is the responsibility of the installer.
• Product failure due to improper installation is not covered under the Warranty.
IMPORTANT SAFETY INSTRUCTIONS
IMPORTANT–PLEASE READ CAREFULLY. FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED TO
AVOID SEVERE OR FATAL SHOCK.
This product requires a three-prong, properly grounded outlet for safe operation. If
not properly grounded, or if the outlet box does not meet electrical requirements
noted (under ELECTRICAL REQUIREMENTS), a qualified electrician should be
employed to correct any deficiencies.
The power cord of this appliance is equipped with a three-prong (grounding) plug
which mates with a standard three-prong (grounding) wall receptacle to minimize the
possibility of electric shock hazard from this appliance.
You should have the wall receptacle and circuit checked by a qualified electrician to
make sure that the receptacle is properly grounded.
Where a standard two-prong wall receptacle is encountered, it is very important to have it replaced with a properly
grounded three-prong wall receptacle installed by a qualified electrician.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT, DEFORM, OR REMOVE ANY OF THE PRONGS FROM THE POWER CORD. DO
NOT USE WITH AN EXTENSION CORD.
Ensure
proper
ground
before use
Note: For easier installation and personal safety, we recommend that two people install this product because of the weight. We highly
recommend professional installation if any electrical or carpentry work is required.
CAUTION
For personal safety, remove the house fuse or open the circuit breaker before beginning
installation to avoid severe or fatal shock injury.
For personal safety, the mounting surface must be capable of supporting the cabinet load, in
addition to the added weight of this 54 pound (24 kilogram) product, plus additional oven loads
of up to 50 pounds (22 kilograms) for a total weight of 104 pounds (47 kilograms).
For personal safety, this product cannot be installed in cabinet arrangements such as an island or
a peninsula. It must be mounted to BOTH a top cabinet AND a wall.
ELECTRICAL REQUIREMENTS
The product rating of your microwave is 120 volts AC, 60 Hertz, 14 amps, and 1.5 kilowatts. This
product must be connected to a supply circuit of the proper voltage and frequency. Wire size
must conform to the requirements of the National Electrical Code or the prevailing local code for this kilowatt rating. The
power supply cord and plug should be brought to a separate 20 ampere branch circuit single grounded outlet. The outlet
box should be located in the cabinet above the microwave oven. The outlet box and supply circuit should be installed by a
qualified electrician and conform to the National Electrical Code or the prevailing local code.

Mounting requirements
• The space between the cabinets must be 30 in. (76.2 cm) wide. If the space between the cabinets is more than 30 in.
(76.2 cm), you’ll need filler material to fill the gap between the microwave and cabinets.
• This microwave is for installation over ranges up to 36 in. (91.4 cm) wide.
• If installing the microwave beneath smooth, flat cabinets, make sure that you leave enough space for the power cord
clearance.
• If you are going to vent your exhaust to the outside, see “Exhaust requirements” on page 7 for exhaust duct
preparation.

Exhaust requirements
Use this section if you plan to vent your microwave outside (top or back exhaust). If you plan to recirculate the air back into
the room, skip to “Removing your microwave” on page 9.
When installing exhaust vents:
• Use the most direct route with as few elbows/transitions as possible. This helps prevent blockages and ensures that the
exhaust is being vented correctly.
• Your microwave is designed to mate with a standard 3-1/4” × 10” rectangular duct. If a round duct is required, a
rectangular-to-round transition adapter must be used. Do not use a duct with a diameter less than 6”.
Note: If a rectangular-to-round transition adapter is used, you must cut the bottom corners of the damper with tin snips to let the
damper have free movement.
• Elbows, transitions, and wall/roof caps add resistance to airflow. Each of these pieces are equivalent to a section of
straight duct that is longer than their actual physical size. When calculating your duct length, add the equivalent
lengths of all the pieces together. For proper airflow, the equivalent airflow should not exceed 140 ft. For example:

Note: Equivalent lengths of duct pieces are based on actual tests and reflect requirements for good venting performance with any
vent hood.

To calculate your equivalent duct length:
1 Write the number of sections used for each of the duct pieces.
2 Multiply the number used by the equivalent length for each duct piece.
3 Add the total equivalent lengths together. This number must be less than 140 ft.

Installing your microwave
Step 1: Find the wall studs
WARNING: Your microwave must be connected to at least one wall stud.
1 Using an edge-to-edge stud finder, locate the edges of the wall stud(s) within the opening.
WARNING: The center of any adjacent wall studs should be 16" or 24" from this mark.
2 Mark the center of each stud, and then draw a vertical line down the center of each stud.

Step 2: Align the rear wall template
Note: If the rear wall template is damaged or unusable, measure and mark the wall with the dimensions at the end of this step.
1 Use a level to make sure that the bottom of the cabinet is level.
2 Draw a vertical line down the center of the wall in the mounting space. This is where the center of your template will be.
3 Draw a horizontal line at the height of the front of your cabinet. This is where the top of your template will be. If the
bottom of your cabinet is flat, make sure that you leave space for the power cord.
Flat bottom:

Notes:
• If installing the microwave beneath smooth, flat cabinets, make sure that you leave enough space for the power cord clearance.
• If cabinets have decorative trim that interferes with the microwave installation, remove the trim to install the microwave properly
and to make sure that it is level.
4 Trim the rear wall template along the dotted line.

6 Mark points A and B on the wall with a pencil.
7 If the stud is on the center line, mark point C on the wall with a pencil.
OR
If the stud is not on the center line, mark two holes on either side of point C that align with the studs.
8 Drill holes through the template at points you marked. If the hole lines up with a stud, drill a 3/16” hole. Otherwise, drill
a 5/8" hole for the toggle bolts.
Note: Depending on your stud locations, your installation may look
different. You should mount to at least one stud.
Note: At least three holes must be used for mounting.
You’ll need:
Ruler or tape measure
Electric drill with 3/16” and 5/8” bits

Step 3: Select a ventilation type
This microwave is designed for three types of ventilation. Select the type of ventilation you want to use, then go to the
corresponding page.
Note: This microwave is shipped assembled for top exhaust ventilation.
Option A - Outside top exhaust (vertical duct): See page 14
Adapter
Option B - Outside back exhaust (horizontal duct): See page 22
Note: If a wall stud is within
6 in. (15.2 cm) of the vertical
center line, you cannot use
this installation option.
Option C - Recirculating (non-vented/ductless): See page 32

Step 4: Option A - Attach the mounting plate to the wall
Note: Depending on
your stud locations,
your installation may
look different. You
should insert toggle
bolts into drywall and
wood screws into
studs.
1 Remove the rear wall template.
2 Remove the mounting plate from the upper foam.
3 Insert the toggle bolt(s) through the front of the mounting plate into the hole(s) that are not going into a stud, and
then attach the toggle wings ¾" onto each bolt. Hold your mounting plate up to holes in your wall to identify the
correct position.
Note: The top of the mounting plate is indicated with an arrow. The mounting plate’s hooks are on the front.

4 Place the mounting plate against the wall and insert the toggle wings into the holes you drilled in the drywall. Pull the
mounting plate away from the wall to help tighten the toggle wings.
