Step 1: Prepare the Electrical Connection

Locate the grounded electrical outlet b for this oven in the upper cabinet a.The outlet should be on a circuit dedicated to the microwave oven (120 V, 60 Hz., AC only) with a 15 or 20 A fused electrical supply.Important: If you do not have the proper wall outlet, you MUST have one installed by a qualified electrician.You will cut the hole c for the power supply cord later when you prepare the wall and upper cabinet in Step 4.Do not use an extension cord. Keep the power cord dry and do not pinch or crush it.Avoid electric shock. This appliance must be grounded.Improper grounding could result in electric shock or other personal injury.Do not, under any circumstances, remove the power supply cord grounding prong.

Step 2: Prepare the Venting System

This oven must be properly vented.You may vent your ductwork in one of three ways. Do not vent into a wall cavity, an attic, or an unused area.The oven is located on an inside wall of your house.CabinetOvenThe oven is located on an outside wall of your house: 3 1/4" x 10" duct c or minimum 6" diameter round duct f.CabinetOven3 1/4" x 10" ductWall capElbowMinimum 6" diameter round duct3 1/4" x 10" to 6" round duct transitionThe oven is located on an outside wall near the roof: 3 1/4" x 10" duct d or minimum 6" diameter round duct e.CabinetOvenRoof Cap3 1/4" x 10" ductMinimum 6" diameter round duct3 1/4" x 10" to 6" round duct transitionIf you choose the rear exhaust method (wall venting or roof venting), be sure there is enough clearance within the wall for the exhaust duct.Keep the length of the ductwork and the number of elbows to a minimum to ventilate your oven efficiently. See examples in next section.Keep the size of the ductwork the same.Do not install two elbows together.Use duct tape to seal all joints in the duct system.Use caulking to seal the exterior wall or roof opening around the cap.After installation, check the outside hood opening and operation.For the outside hood opening and size refer to the upper cabinet template or rear wall template.The ductwork you need for outside ventilation is not included with your oven. See the standard ductwork fittings.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 from sticking.The total length of the duct system, including straight duct, elbows, transitions, and wall or roof caps must not exceed 140 feet.For best performance, do not use more than three 90 degree elbows, and keep the length as short as possible.Below are the standard fittings and their equivalent length in feet.3 1/4" x 10" to 6" transition = 5 ft3 1/4" x 10" roof cap = 24 ft3 1/4" x 10" 90° elbow = 25 ft90° elbow = 10 ft3 1/4" x 10" wall cap = 40 ft45° elbow = 5 ft3 1/4" x 10" flat elbow = 10 ftTo calculate the equivalent length of each duct piece used, see the examples below.For 3 1/4" x 10" systems1/4" x 10" 90° elbow a (1ea)Wall cap b(1ea)Straight duct (8 ft) Total length= 25 ft= 40 ft= 8 ft= 73 ftFor 6" round systemsTransition (1ea)90°elbows b (2ea)Wall cap c (1ea)Straight duct (8 ft)Total length= 5 ft= 20 ft= 40 ft= 8 ft= 73 ft

Step 3: Prepare the Venting Blower

Your microwave oven is shipped with the blower assembled for room venting. You need to adjust the blower if you want wall-venting or roof-venting installation.Electric shock hazard! Unplug unit before working on it.Do not pull or stretch the blower wiring. Pulling and stretching the blower wiring could result in electric shock.To avoid risk of property damage, unplug the microwave oven or disconnect the power at the source by removing the fuse or throwing the circuit breaker.To avoid risk of personal injury, wear protective gloves when handling the mounting plate.Remove any shipping materials and parts from inside the microwave oven. Set them aside for later use.Cover the countertop or cooktop with a thick, protective covering to protect it from damage and dirt.Blanket, cardboard or other coveringIf you have a free-standing range, disconnect it, move it onto a piece of cardboard or hardboard and pull it away from the wall, so that you can get closer to the upper cabinet and back wall for easier measuring and drilling.Locate the exhaust adapter, grease filters and hardware packet.At this point, remove any adhesive tape (if there is any), on the exhaust adapter, the grease filters and the power supply cord.This oven is shipped assembled for room-venting. Remove one or several blower plate mounting screw(s) a and one or two blower unit mounting screw(s) f. Remove the blower plate d from the cabinet. b Blower unit c Knockouts e Back plateCarefully lift the blower unit out of the microwave oven. Use side cutters or tin snips to cut out and remove the knockouts b from the back plate a. Be careful not to distort the back plate. Discard the knockouts.To avoid pinching the blower wire, make sure that it is channeled underneath and between the two exhaust ports when they are rotated.Rotate and reinstall the blower unit a so that the exhaust ports b face the rear of the cabinet and are aligned with the rear knockouts. When you insert the blower unit, the blower wire c must be routed as shown.Attach the blower plate d to the microwave oven so the blower unit exhaust ports c and blower plate opening are aligned. Attach one or two blower unit mounting screw(s) f and then one or several blower plate mounting screw(s) a.b Blower unite Back plateInsert the tabs on each side of the damper into the holes at the inside rear of the adapter.

Attach the exhaust adapter a to the blower plate b with the two tapping screws provided. Make sure that the damper c swings freely.Fire hazard! Correctly install the vent fan before use.When changing the vent fan position for wall venting or roof venting:Properly align the ventilation fan openings and blower plate knockouts.Ventilation fan openings should be completely exposed to the outside.After installation, check the air ventilation path. Refer to step 2 for proper vent selection.Improper installation can cause problems such as:Inability to assemble the blower plate or ventilation motor correctlyAbnormal noise during product operationWeak ventilationProduct overheating and the possibility of product breakdown or fire

Step 4: Prepare the Wall and Upper Cabinet

To avoid personal injury or property damage, do not attempt to install this microwave oven if you cannot find a wall stud. Consult a carpenter or contractor.Using a plumb line and (metal) measuring tape, find and mark the vertical center line on the back wall of the opening.Find and mark one or two points where the studs are on the wall. (Studs are normally 16 inches apart.) Then measure and mark the stud locations. If you cannot find any wall studs, consult a local building contractor.Draw a vertical line on the wall at the center of the 30″ wide opening.Be sure the minimum width is 30 inches.Center the rear wall template b in the space by lining up the plumb line on the wall with the centerline on the template. Then securely tape or tack the rear wall template in place. Make sure the minimum width is 30 inches and that the top of the rear wall template is located a minimum of 30 inches above the cooking surface. Measure the bottom of the upper cabinet frame. Trim edges A, B, and C on the upper cabinet template a so that the template will fit on the bottom of the upper cabinet. If the upper cabinet has a recessed frame, trim the template so it fits inside the recessed area. If needed, the template can be trimmed inside the printed trim lines, as long as you are able to align the centerline correctly. Align the centerline of the upper cabinet template with the centerline of the rear wall template, then securely tape or tack the upper cabinet template in place.To avoid risk of personal injury, electric 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.To avoid risk of personal injury, electric shock or death, cover the edge of the power supply cord hole with the power supply cord bushing.Drill holes on the circles. If there is a stud, drill a 3/16" hole for lag screws. If there is no stud, drill a 3/4" hole for toggle bolts. Make sure to use at least 1 lag screw in a stud, and 2 toggle screws in the drywall or the plaster.Drill a 3/8” hole at points J and K on the upper cabinet template.If the bottom of the upper cabinet is recessed 3/4" or more, you will need 2"x 2" filler blocks b (not included) to provide additional support for the bolts.a Cabinet frontc Cabinet bottom shelfMark the center of each filler block and drill a 3/8” diameter hole at the marks.Align filler blocks b over the two openings in the top of the microwave oven cabinet and attach to the cabinet with masking tape.Cut or drill a 2" diameter hole at the area marked "M power supply cord hole" on the upper cabinet template. If the upper cabinet is metal, you will need to cover the edge of the hole with the power supply cord bushing (supplied) to prevent damage to the cord from the rough metal edge.Cut out the venting areas (with the saber saw)Roof-venting: cut out the shaded area marked L on the upper cabinet template.Wall-venting: cut out the shaded area marked F on the rear wall template.Room-venting: go to Step 5: Install the Mounting Plate.Complete whichever venting system you have chosen. Use caulking compound to seal the exterior wall or roof opening around the wall cap or roof cap.

Step 5: Install the Mounting Plate

The oven must be connected to at least one wall stud.Center the rear wall template in the space by lining up the plumb line on the wall with the centerline on the template. Then securely tape or tack the rear wall template in place. Make sure the minimum width is 30 inches and that the top of the rear wall template is located a minimum of 30 inches above the cooking surface.If the cabinets are not plumb, adjust the rear wall template to the cabinets. If the front edge of the cabinet is lower than the back edge, adjust the template to be level with the cabinet front.Drill holes at points A and B. Drill the third hole inside area C, through one of the bottom holes to match the location of a stud. If there is a stud, drill a 3/16 hole for lag screws. If there is no stud, drill a 5/8 hole for toggle bolts. These holes must be used for mounting. If the holes are not used, the installation will not be secure. The installer must use these holes for proper installation. Use toggle bolts through these holes, unless one of them lines up with a stud. Use a lag screw for studs. Make sure to use at least 1 lag screw in a stud, and 2 toggle bolts in the drywall or the plaster.a Minimum 66" from the floorb For wall - venting onlyc Draw lines on studsd Draw center Linee Mounting platef Support tabCut out the shaded area marked F on the rear wall template for wall-venting.Remove the template from the rear wall.Attach the plate to the wall e. To use spring toggle head bolts d: Remove the toggle wings c from the bolts. Insert the bolts into the mounting plate a and replace the spring toggle head to 3/4 of the length past the bolt ends. Insert the spring toggle head into the holes in the wall to mount the plate. You may pull forward on the plate to help in tightening the toggle bolts. Tighten all bolts.b Space more than wall thicknessf Bolt end

Step 6: Attach the Oven to the Wall

To avoid risk of personal injury or property damage, you will need two people to install this microwave oven.Carefully lift the microwave oven and hang it on the support tabs at the bottom of the mounting plate. Reaching through the upper cabinet, thread the power supply cord a through the power supply cord hole b in the bottom of the upper cabinet.Rotate the microwave oven upward so the top of the oven is against the bottom of the upper cabinet or cabinet frame.Then insert a bolt down through each hole a in the upper cabinet bottom. Tighten the bolts until the gap between the upper cabinet and microwave oven is closed.Roof venting installation: Install the ductwork through the vent opening in the upper cabinet. Use a caulking gun to seal the exterior roof opening around the exhaust cap.a DamperUse the power supply cord clamp b to bundle the power supply cord. Install the power supply cord clamp to the inside of the cabinet using a screw.a DuctGrasp the filter screen with one hand holding the ring and the other hand holding the opposite end. Insert the end of the filter screen without the ring into the opening and slide towards the side of the microwave oven. Insert the ring end of the filter screen into the opening and slide the entire screen towards the center of the microwave until the screen is securely in position. Repeat for the other filter screen.
