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 the 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) plus which mates with a standard three-prong (grounding) wall receptacle to minimize the possibility of electric shock hazard from this appliance. 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.

NOTE:
For easier installation and personal safety, it is recommended that two people install this product.

CAUTION:
For personal safety, remove the house fuse or open the circuit breaker before beginning installation to avoid sever 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 50-70 pound (22.6 – 31.7 kilogram) product, plus additional oven loads of up to 50 pounds (22.6 kgs) for a total weight of 100 – 120 pounds (45.2 – 54.3 kgs). 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 for your microwave is 120 V AC, 60 Hz, 13.5 Amps and 1.5 Kilowatts. This product must be connected 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.

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.

• 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 made with a standard 3 1/4″x10″ rectangular duct. If a round duct is required, a rectangular-to-round transiting adaptor must be used. Do not use less than a 6″ diameter duct.

Maximum duct length:
For satisfactory air movement, the total duct length of 3 1/4″x10″ rectangular or 6″diameter round duct should not exceed 140 equivalent feet.

Elbows, transitions, wall and roof caps, etc.,
present additional resistance to 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.

IMPORTANT:
If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have to be cut to t, using the tin snips , in order to allow free movement of the damper. Equivalent lengths of duct pieces are based on actual with any vent hood.

DAMAGE-SHIPMENT/INSTALLATION

• If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or replacement.
• If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
• If the unit is damaged by the installer (if other than the customer), repair or replacement must be made by arrangement between customer and installer.

You will find the installation accessories contained in a packet with the unit. Check to make sure you have all these parts.

NOTE: Some extra parts are included.

TOOLS YOU WILL NEED

MOUNTING SPACE

NOTES:

• The space between the cabinets must be 24” wide and free of obstructions.
• If you are going to vent your microwave oven to the outside, see the Hood Exhaust section for exhaust duct preparation.
• When installing the microwave oven beneath smooth, flat cabinets, be careful to follow the instruction for power cord clearance. Make sure that you leave enough space for the power cord clearance.

Step-by-Step Installation Guide

PLACEMENT OF THE MOUNTING PLATE

REMOVING THE MICROWAVE OVEN FROM THE CARTON / REMOVING THE MOUNTING PLATE

1. Open the carton and remove the upper foam from the box, but remember to keep the accessories.
2. Pull the oven out of the carton and remove the plastic bag carefully.
3. Take the mounting bracket out from the upper foam.

FINDING THE WALL STUDS

1. Find the wall studs, using one of the following methods.
   • Wall stud finder – a magnetic device that locates nails.
   • Use a hammer to tap lightly across the mounting surface to find a sold sound. This will indicate a wall stud location.
2. After locating the stud(s), find the center by probing the wall with a small nail to find the edges of the wall stud. Then place a mark halfway between the edges. The center of any adjacent wall studs should be 16” to 24” from this mark.
3. Draw a line down the center of the wall studs.

DETERMINING THE TOP LINE OF THE REAR WALL TEMPLATE LOCATION UNDER YOUR CABINET.

There are (3) different types of bottoms on cabinets:

1. Flat bottom Cabinet

2. Recessed frame cabinet bottom
   Must align with the back frame of the cabinet bottom

3. Recessed frame cabinet bottom with front overhang.

TOP LINE OF REAR WALL TEMPLATE
Must align with below cabinet bottom the same distance as the front overhang of the cabinet bottom.

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, top line of rear wall template must align with below cabinet bottom, the same distance as the front overhang depth. This will keep the microwave level.

1. Measure the inside depth of the front overhand.
2. Draw a horizontal line on the back wall an equal distance below the cabinet bottom as the inside depth of the front overhang.
3. For this type of installation with front overhand only, alight the top line of rear wall template with this horizontal line, no touching the cabinet bottom as described in step D.

ALIGNING TOP LIEN OF REAR WALL TEMPLATE

CAUTION:
WEAR GLOVES TO AVOID CUTTING FINGERS ON SHARP EDGES

1. Using a tape measure, draw a vertical line on the wall at the center of the 24” wide space.

2. Tape the rear wall template on the cabinet wall, and align the center markers on the rear wall template to the centerline on wall, making sure it is level and that the top line of the rear wall template is butted up against the bottom edge of the upper cabinet.

3. According to the shape of the cabinet, the location of the rear wall template is compliant with the content C “determining top line of rear wall template location under cabinet”

4. While taping the rear wall template on the wall draw circles on the wall at holes A, B, and C (see illustration above /actual plate marked with arrows). THREE HOLES MUST BE USED FOR MOUNTING. (If there are 2-wall studs in right and left sides based on the center line FOUR holes must be used for mounting).

5. Remove the rear wall template and check the marking based on the actual mount plate (centerline, hole A, B, C).

6. Drill holes on the circle marks (A, B, C)

7. Drill a 3/16” hole at C for wood screw and two 5/8” holes at A, and B for toggle bolts.
   Note: DO NOT MOUNT THE PLATE AT THIS TIME.

8. If the rear wall template is damaged or unusable, measure and mark the wall with the dimensions described in step E.

MARK THE REAR WALL OF THE CABINET WITHOUT THE REAR WALL TEMPLATE

1. The Bottom edge line of the Mounting Plate must be 17 1/8″ (435mm) from the Bottom edge Line of the Upper cabinet and must be level.
2. Mounting plate end holes must be 16 17/25″ (423.8mm) from the Bottom edge Line of the Upper cabinet and must be on an equal line with each other. They must each be 9 9/ “25 (237.8mm) from the center line.
