NOTE:
IT IS RECOMMENDED THAT TWO PEOPLE INSTALL THIS PRODUCT.
IMPORTANT:
KEEP INSTRUCTIONS FOR LOCAL ELECTRICAL INSPECTOR’S USE.

Important Safety Information

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 plug 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.

Safety Instructions
This product requires a three prong grounded receptacle. The installer must perform a ground continuity check on the power outlet box before beginning the installation to insure that the outlet box is properly grounded. 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.
CAUTION:
FOR PERSONAL SAFETY, REMOVE HOUSE FUSE OR OPEN CIRCUIT BREAKER BEFORE BEGINNING INSTALLATION TO AVOID SEVERE OR FATAL SHOCK INJURY. CAUTION:FOR PERSONAL SAFETY, THE MOUNTING SURFACE MUST BE CAPABLE OF SUPPORTING THE CABINET LOAD, IN ADDITION TO THE ADDED WEIGHT OF THIS 85 POUND PRODUCT, PLUS ADDITIONAL OVEN LOADS OF UP TO 50 POUNDS OR A TOTAL WEIGHT OF 135 POUNDS.

•  FOR PERSONAL SAFETY THIS PRODUCT CANNOT BE INSTALLED TO CABINET ARRANGEMENT’S SUCH AS AN ISLAND OR A PENINSULA. IT MUST BE MOUNTED TO BOTH A TOP CABINET AND A WALL.

Electrical Requirements
Product rating is 120 volts AC, 60Hertz, 15 amps, and 1600 ~1700 watts. 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 Electric Code or the prevailing local code for this kilowatt rating. The power supply cord and plug should be brought to a separate 20ampere branch circuit single grounded receptacle. The outlet box should be located near the cord entry point. The outlet box and supply circuit should be installed by a qualified electrician and conform to the National Electric Code or the prevailing local code.
Power supply cord

• a) A short power-supply cord is provided to reduce the risks resulting from 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.

Installation Hardware

The following is a list of parts you may need for installing your Over-the- Range microwave oven. You will find the installation hardware contained in a packet with the unit. Check to make sure you have all these parts. Use this time to become familiar with each piece.

Tools
The following tools may be needed for installation of your microwave oven. Phillips screwdrivers, Electric Drill Motor, 1/2” & 5/8” Wood Bits & 3/16” Drill Bit, Saw to cut exhaust opening, (if needed) or Jig Saw, Tin Snips (if needed), Pencil, Tape Measure, Paper Tape & Duct Tape.
Mounting Space
Your Over- the-Range microwave oven requires mounting space on a wall as shown.

1. A minimum of 30” between wall hung side cabinets is required for installation. Make sure the bottom edge of the top cabinet is at least 66” from the floor and 30” from the cooking surface. And the depth of the cabinet is required less than 12 inch. (max.12inch)
2. For easier access to the hood lamp, the bottom of the microwave oven should be at least 2” above the range backsplash.
3.  If you are going to vent your microwave oven to the outside, see exhaust duct preparation.
4. Designed to be installed in 30” wide cabinet opening.

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:

1. Stud finder-a magnetic device which locates nails.
2. 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.
3.  Draw a line down the center of the studs.

Hood Exhaust Duct
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-to-round 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 constructed 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 equivalent 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.

Roof Cap (24Ft)| 90˚ Elbow (10Ft)| 45˚ Elbow (5Ft)| Rectangular-to-Round Transition Adaptor (5Ft)
