STEP 1 Attach Braces to TV 1.1 Test-fit Brace components on back of TV. Place TV screen-side down on a flat, blanketed surface. Lay out components to check assembly configuration. BACK OF TV {31} 1.3 Select Screws and Spacers. If Spacers {12} are required, choose one of these Screw combinations shown with maximum Spacer usage. {02} {31} {01} {10} M5 {30} {30} {03} {10} {12} {12} {12} {05} 1.2 {04} Determine if TV has a flat or irregular back.
1.4 1.5 Hand-thread screw combination into the TV. Ensure there is adequate thread engagement without hitting the bottom of threaded insert. CAUTION Do not use screws that are too long for the TV’s threaded inserts because it may damage internal components! {12} Attach the Vertical Braces to the back of TV. Install the Vertical Braces {31} so that the bottoms of the braces are between 3" to 10" from the bottom of TV, * centering the braces vertically as much as possible.
STEP 2 Determine Wall Placement 2.1 Measure the distance from the bottom of the Vertical Braces {31} (not the Extenders) to the bottom of the TV/sound bar. * 2.2 Determine the minimum vertical position of the Wall Plate.* Use the Look-up Table below to find the minimum distance between the mantel and the bottom of the Wall Plate {32}. This will be the intersection of the distance from STEP 2.1 and your mantel depth. Write the minimum distance in the box below.
2.3 OPTIONAL Determine a higher vertical position of the Wall Plate. Some customers want the TV centered between the mantel and the ceiling or crown moulding. Others want enough space below the TV for pictures or a center speaker. The TV’s position on the wall is directly related to the placement of the lower Wall Plate. To determine exactly where to place the lower Wall Plate, choose an option below that best describes your scenario and fill in the boxes.
2.6 A. Slide the Wall Plates sideways on the wall until they reach two studs. The Wall Plates {32} don’t have to center-align with the Lifting Arm {35} or the mantel. As long as the Wall Plates are bolted into studs, the Lifting Arm can slide within them, allowing it (and therefore the TV) to center-align with the mantel. BEFORE STUD C L Slide the Wall Plates sideways until they reach two studs, and then mark the center line of the wall onto the Wall Plates.
STEP 3 Attach Mount to Wall 3.1 14 Attach Lifting Arm to Wall Plates. If you arrived from STEP 2.5 then you can attach the Lifting Arm {35} directly to the centers of the Wall Plates (32}. If you arrived from STEP 2.6 then you must align the center of the Lifting Arm to the marks on the Wall Plates, while orienting the Upper and Lower Wall Plate correctly. 3.2 Verify positioning of the mount with stud(s).
3.3 Drill four pilot holes. Cutout shown for reference Use a 7/32" drill bit to create a depth of 2.5" (65mm), including wall covering. Wall covering (drywall) must not exceed a thickness of 5/8". 3.4 Attach the Wall Plates and Lifting Arm (referred to as the “mount” from this step forward) onto the wall. Install Lag Bolts {17} and Washers {11} through the Wall Plate {32} holes, directly into the center of the studs, using the pilot holes drilled in STEP 3.3.
STEP 4 Attach TV to Mount CAUTION Do not damage or scratch the rods of the Gas Springs while performing these steps! 4.1 Insert the Safety Bolt and Safety Nut. Use your body weight to firmly pull down the TV Brace {33} until the Lifting Arm {35} is horizontal to the floor. Continue holding onto the TV Brace. A second person must insert the Safety Bolt {20} through the Safety Hole in the base of the Lifting Arm and install the Safety Nut {27}.
4.2 Carefully hang the TV on the TV Brace. Make sure that all the hooks on the Vertical Braces {31} engage the TV Brace {33}. {35} If the Lifting Arm {35} appears to be too close to the mantle, remove the TV. Refer to STEP 5.3 and make an adjustment to the Bottom Stop positions. Repeat this process until the Lifting Arm is a safe distance from the mantle when the TV is installed. {33} {31} Do not allow the TV to drop far enough to cause the Lifting Arm to hit the mantel. 4.
STEP 5 Make Final Adjustments Lifting Force Side Swivel Stops Bottom Stop Post-Leveling 5.1 Adjust the Lifting Force for the TV. First, review all the images in this step. With Safety Bolt {20} in place, use a 10–14mm socket wrench with an extension to adjust the Tension Bolt {41} (the long bolt inside the Lifting Arm {35}). LIGHTER TV? HEAVIER TV? For heavy TVs, turn the Tension Bolt clockwise in order to pull the Gas Springs {38} DOWN and increase the lifting force.
5.2 Adjust the Side Swivel Stop positions, if necessary. TV BRACE To keep your TV from bumping the mantel or wall, loosen the Locknuts {23} and adjust the Swivel Stop Screws to the desired stopping left and right positions. Tighten both Locknuts after the adjustments are made. If no swivel is desired, it may be necessary to remove the Locknuts and reattach them on the other side of the Swivel Bracket so that the Screws can be threaded out to their maximum length. 5.
5.5 Verify the proper Lifting Performance (Force). MantelMount is designed to keep the TV securely in the UP position while also allowing it to gently rest in the DOWN position. Refer to diagram below. If you need to make adjustments, reinsert the Safety Bolt and then repeat STEP 5.1. 5.6 Make Post-Leveling adjustments, if necessary. Place a level on top of the TV while it’s in the UP position.
TROUBLESHOOTING TIPS Customer satisfaction is our top priority! Following are solutions for the most common installation challenges. For further assistance, visit www.mantelmount.com/troubleshooting or contact Customer Support at 1-800-897-9755 ext.1 or support@mantelmount.com, Monday through Friday, 7am to 4pm PST. NOTE: In rare cases, one troubleshooting adjustment may create the need for another. Be prepared for some trial and error.
TROUBLESHOOTING TIPS CONTINUED FROM PREVIOUS PAGE MOUNT PERFORMANCE ISSUE SOLUTION (May require some trial and error to reach optimal performance.) TV is tilting forward when in the UP position. This is generally an indication that the Lifting Force is not set tight enough in the UP position (see Step 5.1). Slightly turn the Tension Bolt clockwise and try again. The goal is to adjust the Lifting Force just enough for the TV to no longer tilt in the UP position.
