Step 1: Attach Braces to TV

Objective: To attach the TV braces to the back of the television.

In order for the TV to hide the Mount on the wall, the Braces must be at least 3" higher than the bottom of the TV (or Soundbar if one is installed). If you are using an RB100 Recess Box, they must be 6" higher to hide the Recess Box.

1. Test-fit Brace components: Place the TV screen-side down on a flat, blanketed surface. Lay out components to check assembly configuration. Refer to Step 1.8 if installing a soundbar.
2. Determine TV Back Type: Check if the TV has a flat or irregular back. An irregular back may require Spacers {12} and longer Screws to fill gaps between the Vertical Brace {31} and the TV. The Braces must be parallel to the television screen.
3. Select Screws and Spacers: If Spacers {12} are required, choose appropriate Screw combinations shown in the diagram, using maximum Spacer usage.

Diagram Description: Shows two configurations for attaching braces to a TV back: 'Flat Back TV' and 'Irregular Back TV'. For irregular backs, it illustrates the use of Spacers {12} and longer screws. It also shows a 'Recessed Threads' variation for irregular backs. A visual guide details screw and spacer combinations for M5, M6, and M8 screws, indicating which parts to use based on the VESA hole size.

4. Hand-thread screw combination: Insert the selected screws and spacers into the TV's threaded inserts. Ensure adequate thread engagement without bottoming out the screw.

❗ Caution: Do not use screws that are too long for the TV's threaded inserts, as this may damage internal components!

5. Attach Vertical Braces {31}: Install the Vertical Braces {31} so their bottoms are between 3" and 10" from the bottom of the TV (or Soundbar). Center the braces vertically as much as possible.

*If installing this mount with a MantelMount RB100 Recess Box, the bottom of the Vertical Brace must be 7"-10" from the bottom of the TV (or 7" from the bottom of the Soundbar if one is installed).

Diagram Description: A side view shows the Vertical Braces {31} attached to the TV. An enlarged view shows the required gap in the threaded TV insert for maximum stability. The text "VERTICAL BRACES MUST ALWAYS BE INSTALLED HIGHER THAN THE BOTTOM OF THE TV" is prominent, with a measurement indicator showing "3 to 10 * INCHES".

6. If lower VESA holes are less than 3" from TV bottom: Connect the Vertical Braces {31} through the UPPER VESA holes only. If attaching through a slot, hand-thread the screw, slide the brace upward until the screw meets the bottom of the slot, then tighten. You must attach the Brace Extenders {30} as described in STEP 1.7, and also attach the LOWER VESA hole through the Brace Extender.

Diagram Description: A side view illustrates attaching Vertical Braces {31} using only the upper VESA holes, with a Brace Extender {30} connecting to the lower VESA hole.

7. Attach Horizontal Brace {55} to Brace Extenders {30}: Slide one Brace Extender {30} onto each end of the Horizontal Brace {55}. Align the Brace Extenders with the Vertical Braces {31} (already mounted to the TV). Attach the Horizontal Brace to the Brace Extenders using Screws {15}.

Diagram Description: Shows the Horizontal Brace {55} with Brace Extenders {30} slid onto its ends. These are then aligned and attached to the Vertical Braces {31} using screws {15}.

8. Optional: Attach Sound Bar Wings {52}: Use Screws {16}, M6 Washers {10}, and Nuts {23} to attach the Sound Bar Wings {52} to the Horizontal Brace {55}. Position the wings to fit the mounting holes of the soundbar.

Diagram Description: Shows Sound Bar Wings {52} being attached to the Horizontal Brace {55} with hardware.

Sound Bar Wing Installation: Arrange Sound Bar Wings and sound bar to work with the Visual Heat Sensor {219}. The wings may be positioned and rotated so the sensor reaches below the soundbar. For example, if a soundbar is tall, the Brace Extenders {30} and Horizontal Brace {55} can be attached lower on the Vertical Braces {31} while the Wings point upwards to align with the soundbar's mounting holes.

Diagram Description: Illustrates two scenarios for soundbar installation: a 'TALLER SOUND BAR' and a 'WIDER SOUND BAR', showing how the wings and braces can be adjusted. It also shows the Visual Heat Sensor {219} positioned below the soundbar.

9. Attach Visual Heat Sensor {219}: Attach the Visual Heat Sensor {219} with Screws {15} to the Horizontal Brace {55}. Set the height so the sensor is as visible as desired.

Note: If using the minimum height from the chart in Step 2.2, keep the exposed heat sensor pad no more than 1" below the TV or soundbar. When first moving the mount down, ensure the visual heat sensor clears the mantel.

Diagram Description: A side view shows the Visual Heat Sensor {219} attached to the Horizontal Brace {55} with a measurement indicator showing "1" Max below TV or Soundbar".

Purpose of Heat Sensor: The Visual Heat Sensor turns red if the temperature above the fireplace exceeds a safe 110°F, serving as a visual cue to raise the TV or turn off the fireplace.

Step 2: Determine Wall Placement

Objective: To determine the correct vertical position for the Wall Plate {32}.

1. Measure Distance: Measure the distance from the bottom of the Vertical Braces {31} (not the extenders) to the bottom of the TV/sound bar.

Diagram Description: Shows a measurement being taken from the bottom of the Vertical Brace {31} to the bottom of the TV/soundbar.

2. Determine Minimum Vertical Position of Wall Plate: Use the lookup table to find the minimum distance between the mantel and the bottom of the lower Wall Plate {32}. This is determined by the distance measured in STEP 2.1 and the mantel depth.

Minimum Vertical Position Lookup Table:

Distance from STEP 2.1	Mantel Depth (inches)
(inches)	8" or Less	9"	10"	11"	12"	13"	14"	15"-16"
3"	3.00	4.75	5.25	5.75	6.25	6.75	7.25	8.25
4"	4.50	5.75	6.25	6.75	7.25	7.75	8.25	9.25
5"	5.50	6.75	7.25	7.75	8.25	8.75	9.25	10.25
6"	6.50	7.75	8.25	8.75	9.25	9.75	10.25	11.25
7"	7.50	8.75	9.25	9.75	10.25	10.75	11.25	12.25
8"	8.50	9.75	10.25	10.75	11.25	11.75	12.25	13.25
9"	9.50	10.75	11.25	11.75	12.25	12.75	13.25	14.25
10"	10.50	11.75	12.25	12.75	13.25	13.75	14.25	15.25

*If installing this mount with a MantelMount RB100 Recess Box, the bottom of the Vertical Brace must be 7"-10" from the bottom of the TV (or 7" from the bottom of the Soundbar if one is installed).

Most customers want their TV mounted as close to the mantel as possible. If this describes you, proceed to STEP 2.4. If you want the TV higher on the wall (e.g., centered between the mantel and ceiling), continue to STEP 2.3.

3. Determine a Higher Vertical Position (Optional): For scenarios where the TV should be centered between the mantel and ceiling, or to allow space below the TV for decor or a center speaker.
   • Option 1: Centered between mantel and ceiling/crown molding.
   • Option 2: Specific distance above mantel.
     1. Record measurements: Wall Space Height (A), TV Height (B), Distance from STEP 2.1 (C).
     2. Calculate: (A) - (B) = (D). Then (D) / 2 = Target height above mantel for TV center.
     3. Add (C) and (D) to determine how many inches above the mantel to place the lower Wall Plate holes (E). (C) + (D) = (E).
     4. Alternatively, for Option 2, record the specific number of inches you want between the mantel and the TV (or TV with sound bar). Add this to (C) to find (E).

NOTE: Distance "E" below must always be at least the minimum distance determined in STEP 2.2.

Diagram Description: Illustrates two options for calculating the Wall Plate position. Option 1 involves centering the TV between mantel and ceiling. Option 2 involves a specific distance above the mantel. Both options require measuring Wall Space Height (A), TV Height (B), and the distance from Step 2.1 (C), then performing calculations to find the target height (E) for the lower Wall Plate holes.

4. Find Center of Mantel and Studs: Measure and mark the center line of the mantel on the wall. Use a stud finder to locate two studs, one on each side of the centerline. Mark the center of each stud at the determined height (from Step 2.2 or 2.3). Lag Bolts must be installed into the CENTER of the studs.

Diagram Description: Shows a wall with a marked center line for the mantel. A stud finder is depicted locating studs. An awl is shown poking the drywall to find the exact center of a stud.

5. Align and Mark Wall Plate: Align the arrows on the Wall Plate {32} pointing upward. Center and level the plate above the mantel at the determined height. Mark the 4 spots for lag bolts directly on the center of the studs.

Diagram Description: Shows the Wall Plate {32} being held against the wall, centered and leveled above the mantel, with marks made for drilling lag bolt holes into the studs.

6. Pre-drill Holes: Use a 7/32" drill bit to pre-drill the 4 holes to a depth of 2.5 inches (65mm), including wall covering.

Note: Wall covering (drywall) must not exceed 5/8" thickness.

7. If necessary, move Wall Plates to clear an outlet: If an electrical outlet impedes installation and cannot be professionally relocated, you can move the Wall Plates up or down to clear the outlet. Ensure the LOWER Wall Plate is not placed below the Minimum Distance (Step 2.2). IMPORTANT: You must move the Vertical Braces {31} on the back of the TV by the same amount (e.g., move braces down 2" if wall plates were moved down 2"). The bottom of the Vertical Braces must remain between 3" to 10" from the TV bottom. If the outlet is directly behind the Lifting Arm, the Wall Plates must be moved up.

Diagram Description: Two diagrams illustrate the scenario: 'BEFORE Wall plate impeded by outlet' and 'After Wall Plate lowered to clear outlet'. Another set shows 'BEFORE If the wall plate sits directly behind lifting arm' and 'After Wall plate moved up to clear outlet'.

8. Optional: Attaching the MM815 Lifting Arm into the RB100 Recess Box Kit: If installing with an RB100 Recess Box, refer to the RB100 manual for height charts. Insert the MM815 Lifting arm into the RB100, aligning screw holes. Use four {14} M8x16 screws. Rest the base of the lifting arm on M6 cap screws. Once holes align, insert and tighten M8x16 screws. Connect power and use the remote to lower the arm to expose lower holes (3 and 4). Gently push the arm up and back to secure the wall bracket to the RB100. Insert and tighten screws for holes 3 and 4. Tighten all four screws.

Diagram Description: Illustrates inserting the MM815 Lifting Arm into the RB100 Recessed box, showing alignment of screw holes. It details using M8x16 screws and the process of securing the arm.

Step 3: Attach Mount to Wall

Objective: To securely attach the mount components to the wall.

1. Attach Wall Plate {32}: Use Lag Bolts {17} and Washers {11} to attach the Wall Plate {32} (arrows up) directly into the center of the studs using a 13mm wrench.

❗ Caution: Do not overtighten Lag Bolts {17}. Tighten only until the washers are firmly against the wall plate. Damage due to overtightening can cause property damage or injury.

2. Attach Lifting Mechanism {35}: Insert the bottom tabs of the Lifting Mechanism {35} into the slots of the Wall Plate {32}, then slide the top into position. Align all four holes and install Screws {14}. Tighten securely.

Note: Do NOT let go of the Lifting Mechanism {35} until Screws {14} are installed.

Diagram Description: Shows the Lifting Mechanism {35} being slotted into the Wall Plate {32} and secured with screws {14}.

3. Power Up and Test: Plug the Power Supply into the mount and then into a wall socket. The TV remote should work out of the box. Move the Mount Down approximately 2 inches by holding the [DOWN] button.

If TV remote does not work, it needs to be paired:

1. Unplug Power to mount for 30 seconds.

6. Swivel Safety Clutch Recalibration: The swivel has a friction clutch that disengages to prevent damage if it hits an obstruction. If this happens, the swivel needs recalibration. To recalibrate, auto-move the mount to the top position: Press RUN, then press the [UP] button within 3 seconds. The mount will move to the top position and recalibrate. The System Reset function can also recalibrate the swivel.

Diagram Description: Shows pressing RUN, then pressing the [UP] button within 3 seconds.

Note: If the clutch is engaged, the mount may swivel slightly when coming down. To fix this, manually center the mount at zero degrees swivel by rotating the TV with your hands, overriding the clutch. The mount is at zero degrees swivel after recalibration (driving to the top position), then move the mount straight down.

7. Attach the TV Brace {33} to the Lifting Arm {35}: Manually swiveling the Swivel Plate can make accessing screw holes easier. Level the TV Brace and tighten the 4 screws {15}.

NOTE: After the TV is mounted, you may need to adjust these screws for final Post-Leveling adjustments (Step 5.6).

Diagram Description: Shows the TV Brace {33} being attached to the Lifting Arm {35} using screws {15}.

Step 4: Attach TV to Mount

Objective: To securely attach the television to the mount.

NOTE: These next steps will require two people.

⚠️ WARNING! Do not put hands into the Lifting Mechanism. The power of the Lifting Mechanism can cause bodily injury!

⚠️ Pinching and Crushing Hazard: The wall mount actuation is very strong, do NOT run the mount when anyone is near the mount. Do NOT have any part of the body in the mount or between the TV and Wall.

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.

Mount Space Issues

• Issue: The wall covering is made of brick or stone, or the drywall/stucco wall covering is thicker than 5/8".
• Solution: It's possible to install MantelMount by using concrete anchors (included) with the Lag Bolts {17}, PROVIDED the brick/stone/wall is structurally sound, several inches thick, and can handle four times the weight of the TV and mount. Working with a masonry professional is recommended. Contact Customer Support for guidance.
• Issue: A single wood stud is centered on my wall.
• Solution: MantelMount recommends adding more support so the mount can attach to the equivalent of 2 studs.

Mount Performance Issues

• Issue: Swivel is off.
• Solution: Swivel needs to be recalibrated. Press RUN, then press the [UP] button within 3 seconds to allow the mount to move all the way to the top position. The mount should be recalibrated. You can also run the System Reset function (See page 5).

NOTE: The Swivel on the mount has a friction clutch that automatically disengages to avoid damage if the mount swivels into something, or someone swivels the mount manually. If that happens, the swivel will be out of position and may not work as expected. Recalibration is needed immediately.

• Issue: TV isn't vertical in out and bottom positions.
• Solution: See Step 5.4 to adjust the Bottom/Out Position tilt.
• Issue: TV isn't vertical in the Top Position.
• Solution: See Step 5.5 to adjust the Top Position tilt.
• Issue: TV is not returning to the same memory position.
• Solution: 1. Press RUN. 2. Press the memory button (1 or 2) within 3 seconds. 3. Allow the mount to move all the way to the top position and wait 5 seconds. 4. The mount should be recalibrated. 5. Alternatively, run System Reset (See page 5).
• Issue: Mount does not move.
• Solution: Try the following: 1. Run System Reset (see page 5). 2. Check that power is getting to the mount (green light on the plug). 3. Replace the CR2032 battery in the remote. 4. Check that wires in the mount are plugged in and not damaged. 5. Pair the RF remote (see Step 3.3). 6. The Bottom Limit may have been set too high; clear the Bottom Travel Limit (see page 5). ⚠️ Warning: The mount can now travel all the way down, and the Bottom Limit will have to be redone (see section 3.5).
• Issue: Mount is acting weird.
• Solution: Run System Reset (see page 5).
• Issue: Mount swivels a little when coming down.
• Solution: Manually center the mount at zero degree swivel by rotating the TV with your hands, overriding the clutch. The mount is at zero degrees swivel after recalibration (drive the mount to the top position), then move the mount straight down.

TV Leveling Issues

• Issue: TV is not level in the UP and/or DOWN positions.
• Possible Cause: The mantel, ceiling, or floor may not be level. Vertical Braces {31} aren't evenly attached to the back of the TV. Wall Plates {32} aren't level. The Top Stops aren't evenly set. TV is heavier on one side.
• How to Check: Compare TV level with that of the mantel and floor. Look at the back of the TV and ensure the top of the Vertical Braces are offset from the top of the TV the same distance. Use a level on top of Wall Plates to verify they are level.
• Solution:
  1. Adjust until visibly satisfactory.
  2. Move the TV down.
  3. Make Post Leveling adjustments (Step 5.6) and match the level readings of the mantel with the TV.
  4. Ensure Top Tilt Adjustment is the same on each side of the mount (Step 5.5).
• Issue: TV is level in the UP position, but unleveled in the DOWN position, or vice versa.
• Solution:
  1. Remove electrical and signal cables (Step 4.5).
  2. Detach the TV Brace {33} from the Vertical Braces {31} (Step 4.4).
  3. Remove the TV from the TV Brace (Step 4.2) and lay TV face down on a blanketed surface (Step 1.1).
  4. Remove the Vertical Brace(s) {31} as necessary.
  5. Reposition the Vertical Braces so they are properly parallel to one another, then repeat Step 1, Step 4, and if necessary, Step 5.
• Issue: TV is level in the UP position, but unleveled in the DOWN position, or vice versa.
• Solution:
  1. Remove electrical and signal cables (Step 4.5).
  2. Detach TV Brace from Vertical Braces (Step 4.4).
  3. Remove the TV from the TV Brace (Step 4.2) and lay TV face down on a blanketed surface (Step 1.1).
  4. Slightly loosen all four Lag Bolts {17} (Step 3.1).
  5. Adjust Wall Plates {32} so they are level.
  6. Hold Wall Plates in a level position and firmly tighten the four Lag Bolts. Heed warning in Step 3.1.
  7. Once the Wall Plates are level, repeat Steps 3, 4, and 5.
• Issue: TV is level in the UP position, but unleveled in the DOWN position, or vice versa.
• Solution: Follow the instructions in Step 5.5. Be prepared for some trial and error. If adjusting the Top Stops doesn't solve the problem, try the solution below for when a TV is heavier on one side.
• Issue: TV is heavier on one side.
• Solution: Attach a counterweight to the back of the TV. Contact Customer Support for assistance.

Product Overview & Adjustments

The MM815 Motorized Drop Down TV Mount offers advanced functionality with three primary adjustments that must be made after installation for proper operation:

• Bottom Travel Stop: Adjusted using the remote control to set the lowest possible position.
• Centering Cams: Automatically swivel the TV to center while raising, helping to avoid permanent obstacles.
• Side-to-Side Swivel Stops: Adjusted via remote control and physical screws to prevent the TV from swiveling into the mantel or wall.

Diagram Description: A diagram shows the overall dimensions of the mount, including maximum drop (37.5 inches), thickness (24.7 inches), and clearance. It also illustrates the swivel range (30° Left / 30° Right) and the tilt sequence as the mount lowers (tilts down, normalizes, becomes vertical about 6 inches down).

Note: As the mount lowers, it first tilts down. As it continues lowering, it normalizes, becoming vertical about 6 inches down.
