INSTALLATION INSTRUCTIONS MICROWAVE OVEN PLEASE READ AND SAVE THESE INSTALLATION INSTRUCTIONS. P/No.: 3828W5U0492 www.lg.
YOUR SAFETY FIRST BEFORE YOU START • Proper installation is the installer's responsibility! – Read the entire manual before you begin. The Model number label is located on the front of oven, behind doon See Figure 1. Mounting plate is located on back side of microwave oven. See Figure 2. BE SURE TO READ THE FOLLOWING SAFETY INSTRUCTIONS: Mounting Plate Model Number Plate Model Number Plate Mounting Plate Figure 1 Figure 2 WA R N I N G For Your Safety • You will need TWO people to install this oven.
YOUR SAFETY FIRST • THIS APPLIANCE MUST BE GROUNDED! – If there is an electrical short circuit, grounding reduces the risk of electrical 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. • Place the plug into a properly installed and grounded outlet. See Figure 3. PROPERLY POLARIZED AND • Do not use an extension cord. GROUNDED OUTLET • Keep the power cord dry and do not pinch or crush it.
YOUR SAFETY FIRST • MAKE SURE YOU HAVE ENOUGH SPACE AND SUPPORT. – Mount the oven against a flat, vertical wall, so that it is supported by the wall. The wall should be constructed of minimum 2" x 4" wood studding and 3/8" thick drywall or plaster/lath. – ATTACH AT LEAST ONE of the two lag screws supporting the oven to a vertical, 2" x 4" wall stud. – DO NOT mount the microwave oven to an island or peninsula cabinet. – BE SURE the upper cabinet and rear wall structures are able to support 150 lbs.
PARTS, TOOLS, MATERIALS THE FOLLOWING PARTS ARE SUPPLIED WITH THE OVEN: NOTE: Depending on your ventilation requirements, you may not use all of these parts.
PARTS, TOOLS, MATERIALS You will need the following tools and materials for the installation: Carton or other heavy material for covering the counter top.
STEP 1: PREPARE THE ELECTRICAL CONNECTIONS WA R N I N G AVOID ELECTRICAL SHOCK! THIS APPLIANCE MUST BE GROUNDED! 1. Locate the grounded electric outlet for this oven in the cabinet above the oven, as shown in Figure 5. NOTE: The outlet should be on a circuit dedicated to the microwave oven (120V, 60 Hz., AC only) with a 15 or 20A fused electrical supply. Upper Cabinet IMPORTANT: If you do not have the proper wall outlet, you MUST have one installed by a qualified electrician.
STEP 2: PREPARE THE VENTING SYSTEM NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork fittings and length are shown in Figure 10, page 9. WA R N I N G THIS OVEN MUST BE PROPERLY VENTED! You may vent your oven in one of three ways. Do NOT vent into a wall cavity, an attic, or an unused area. Roof-venting If your oven is located on an outside wall near the roof, as in Figures 7 (3 1/4" x 10" duct) and Figure 9 (6" round duct.
Standard Fittings NOTE: If the existing duct is round, you must use a rectangular-to-round adapter, with a rectangular 3" extension duct installed between the damper assembly and the adapter to prevent the exhaust damper’s sticking. Duct Length The total length of the duct system, including straight duct, elbows, transitions, and wall or roof caps must not exceed the equivalent of 140 feet. For best performance, do not use more than three 90 degree elbows, and keep length as short as possible.
STEP 3: PREPARE THE VENTING BLOWER WA R N I N G ● To avoid risk of property damage, unplug the microwave oven or disconnect power at source by removing fuse or throwing circuit breaker. ● To avoid risk of personal injury, wear protective gloves when handling mounting plate. DO NOT PULL OR STRETCH THE BLOWER WIRING! Pulling and stretching the blower wiring could result in electrical shock. ● Your microwave oven is shipped with the blower assembled for room venting.
4. Reassemble the blower wire. See Figure 15. 5. Rotate the unit so that the exhaust ports face the rear of the cabinet. See Figure 17. When you insert blower unit, blower wire must be like figure 16. 6. Place blower unit back into cabinet. Check that the exhaust ports face towards the rear of the cabinet. See Figure 17. 7. Reattach the blower plate to cabinet so the exhaust ports and blower plate opening are aligned. Attach with one blower unit mounting screw and then one blower plate mounting screw.
STEP 4: PREPARE THE WALL & UPPER CABINET WA R N I N G To avoid personal injury or property damage, do not attempt to install this microwave oven if you cannot find a wall stud. Measure And Track/Tape Up The Templates 1. Using a plumb line and measuring tape, find and mark the vertical center line on the back wall, as in Figure 24. 2. Find and mark one or two points where the studs are on the wall. Then measure and mark the stud locations.
WA R N I N G To avoid risk of personal injury, electrical shock or death: Note where electrical outlets and electrical wires are before you drill into the wall. Locate and disconnect power to any electrical circuits that could be affected by installing this oven. WA R N I N G To avoid risk of personal injury, electrical shock or death, cover the edge of the power supply cord hole with the power supply cord bushing. Drill The Holes In The Wall And Upper Cabinet. cabinet front filler block 1.
STEP 5: INSTALL THE MOUNTING PLATE The Oven Must Be Connected To At Least One 3/16 Hole on Studs 5/8 Hole on Dry wall Only Wall Stud. 1. Draw a vertical line on the wall at the center of the 30 wide space. Use the mounting plate as the template for the rear wall. Place the mounting plate on the wall, making sure that the tabs are against the bottom of the cabinet. Line up the notch and center line on the mounting plate to the center line on the wall. Minimum 66" From the Floor For WallVented Only 2.
For Wall-Vented Make the box cutout for the rear wall duct. – 1 piece mounting plate: Using a pencil, put dots through slots F and G, and through holes H and I. Remove the mounting plate and draw lines extending through the points. This will give the location and size of the box cutout for the rear wall duct. (Figure 30) – 3 pieces mounting plate: Use the wall template to determine the location and size of the box cutout for the rear wall duct.
STEP 6: ATTACH THE OVEN TO THE WALL WA R N I N G To avoid risk of personal injury or property damage, use will need two people to install this microwave oven. 1. Carefully lift microwave oven and hang it on support tabs (See Figure 28) at the bottom of the mounting plate.Reaching through upper cabinet, thread power supply cord through the power supply cord hole in the bottom of the upper cabinet. See Figure 32. power cord power cord hole 2.
STEP 6: ATTACH THE OVEN TO THE WALL 5. Roof venting installation: See Figure 34. Install ductwork through the vent opening in the upper cabinet. Complete the venting system through the roof according to the method needed. See "Prepare The Venting System" STEP 2. Use caulking gun to seal the exterior roof opening around the exhaust cap. See Figure 7 on page 8. 6. Use the power supply cord clamp to bundle the power supply cord.
