MM815 Installation Steps

NOTE: These Next Steps Will Require Two People ?

STEP 1: Attach Braces to TV

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

Reference Step 1.2 for proper TV Brace configuration.

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. If installing a sound bar, refer to STEP 1.8.

1.2 Determine if TV has a flat or irregular back.

An irregular back will require Spacers {12} and longer Screws to fill spaces between the Vertical Brace {31} and the TV. The Braces must be parallel to the television screen.

Flat Back TV: {31}
Irregular Back TV: {31} {12}
Irregular Back TV (Recessed Threads): {31} {12}

1.3 Select Screws and Spacers.

If Spacers {12} are required, choose one of these Screw combinations shown with maximum Spacer usage.

Diagram Description: Shows screw combinations for M5, M6, and M8 sizes, indicating which screws and spacers to use for different TV back types. The diagram shows the back of a TV with mounting holes and illustrates how to select the correct screws and spacers from the provided hardware.

1.4 Hand-thread screw combination into the TV.

Ensure there is adequate thread engagement without hitting the bottom of the threaded insert.

ⓘ CAUTION: Do not use screws that are too long for the TV's threaded inserts because it may damage internal components!

Diagram Description: Illustrates hand-threading a screw into a TV insert, showing the need to leave a gap for proper thread engagement and showing the screw after assembly. It highlights the importance of thread engagement and avoiding damage to internal components.

1.5 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 (*or Soundbar if one is installed), centering the braces vertically as much as possible.

Diagram Description: Shows side view of TV back with vertical braces {31} attached, indicating the 3" to 10" measurement from the bottom of the TV. Also shows the requirement that vertical braces must always be installed higher than the bottom of the TV.

1.6 If the lower VESA holes are less than 3" from the bottom of the TV:

Connect the Vertical Braces {31} through the UPPER VESA holes only, so that the bottom of the braces are between 3" to 10" from the bottom of the TV. *

If the only option is to attach the Vertical Braces to the Upper VESA holes through a slot: 1) Hand-thread the screw through the slot; 2) slide the Vertical Brace upward until the screw meets the bottom of the slot; and 3) tighten the screw.

You must attach the Brace Extenders {30} to the Vertical Braces as described in STEP 1.7. However, you must also attach the LOWER VESA hole through the Brace Extender as shown.

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

Diagram Description: Shows how to attach vertical braces using only upper VESA holes if lower holes are too close to the bottom. Also shows the optional use of brace extenders {30} and how to attach them. It includes a note about the RB100 Recess Box installation.

1.7 Attach the Horizontal Brace to Brace Extenders.

Slide one Brace Extender {30} onto the left end of the Horizontal Brace {55}, then slide the other Brace Extender onto the opposite right end.

Align the Brace Extenders with the Vertical Braces (that are already mounted to the back of the TV) while positioning the Horizontal Brace so that it extends an equal amount on either side of the Brace Extenders. Attach Horizontal Brace to Brace Extenders w/Screws {15}.

Diagram Description: Shows attaching brace extenders {30} to the horizontal brace {55} and then aligning and attaching this assembly to the vertical braces {31} on the TV.

1.8 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 sound bar. Install sound bar. See below for Sound Bar Wing installation information.

Diagram Description: Shows attaching sound bar wings {52} to the horizontal brace {55} using screws {16}, washers {10}, and nuts {23}. Also shows how to arrange wings and sound bar to work with the visual heat sensor {219}.

1.9 Attach Brace Extenders to the Vertical Braces.

Slide the Brace Extenders {30} (with the Horizontal Brace {55} now attached to them) onto the Vertical Braces {31}. Position it so that the Horizontal Brace will be hidden by the TV. Use Screws {18} and Nuts {23} to attach.

Diagram Description: Shows sliding brace extenders {30} onto vertical braces {31} and securing them with screws {18} and nuts {23}.

1.10 Attach Visual Heat Sensor to the Horizontal Brace.

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

Note: If using the minimum height from 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: Shows attaching the visual heat sensor {219} to the horizontal brace {55} with screws {15}. A side view indicates the 1" maximum clearance below the TV or soundbar.

Protect the TV with the Visual Heat Sensor: The Visual Heat Sensor turns red if the temperature above the fireplace exceeds a safe 110°F – a visual cue that either the TV needs to be raised to the UP position or the fireplace needs to be turned off.

STEP 2: Determine Wall Placement

Diagram Description: Shows the TV brace assembly attached to the TV, with a measurement arrow indicating the distance from the bottom of the vertical braces to the bottom of the TV/soundbar.

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 lower Wall Plate {32}. This will be the intersection of the distance from STEP 2.1 and the mantel depth. Write the minimum distance in the box below.

DISTANCE FROM 2.1	DEPTH OF MANTEL
DISTANCE FROM 2.1	8" OR LESS	9"	10"	11"	12"	13"	14"	15"	16"
3"	4.50	4.75	5.25	5.75	6.25	6.75	7.25	8.25	9.25
4"	5.50"	5.75	6.25	6.75	7.25	7.75	8.25	9.25	10.25
5"	6.50"	6.75	7.25	7.75	8.25	8.75	9.25	10.25	11.25

10"	11.50"	11.75	12.25	12.75	13.25	13.75	14.25	15.25	16.25

VALUE FROM LOOK-UP TABLE: ______

MINIMUM DISTANCE BETWEEN MANTEL AND LOWER WALL PLATE HOLES: ______

*If installing this mount with a MantelMount RB100 Recess Box, the bottom of the Vertical Brace must be 7"-10" from the bottom of 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, go directly to STEP 2.4. However, if you want the TV higher on the wall (such as centered between the mantel and ceiling) e.g. for extra space on the mantel for pictures or a center speaker, continue to STEP 2.3.

2.3 Determine a higher vertical position of the Wall Plate.

Some customers want the TV centered between the mantel and the ceiling or crown molding. 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.

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

Option 1: I want the TV centered between the mantel and ceiling/crown molding.

Record measurements already taken: Wall Space Height (from pg. 2) (A), TV Height (from pg. 2) (B), Distance from STEP 2.1 (from pg. 8) (C)
Subtract the TV Height (B) from the Wall Space Height (A), then divide by 2: (A) - (B) / 2 = (D)
Add (C) and (D) to determine how many inches above the mantel to place the lower Wall Plate holes: (C) + (D) = (E)

Option 2: I want the TV a specific distance above the mantel.

Record distance from STEP 2.1 (from pg. 8) (C)
Write the specific number of inches you want between the mantel and the TV (or TV with sound bar): (D)
Add (C) and (D) to determine how many inches above the mantel to place the lower Wall Plate holes: (C) + (D) = (E)

Diagram Description: Shows two options for determining wall plate placement. Option 1 involves centering between mantel and ceiling. Option 2 involves a specific distance above the mantel. Both options require recording measurements and performing calculations to find the final height (E). Arrows indicate distances.

2.4 Find the center of your mantel and the centers of two studs.

Measure and mark the center line of the mantel onto the wall with tape. Next, use a stud finder to locate two studs, one on each side of the centerline. (If you prefer to use one center stud alone, see "Mount Space" in the Troubleshooting Tips on page 22.) Then, at the height from either Step 2.2 or 2.3, locate the center of the stud(s) by poking a sharp awl or finish nail through the drywall to find each stud edge. Mark these center spots on the wall. Lag Bolts must be installed into the CENTER of the studs in STEP 3.1.

Diagram Description: Shows using a stud finder and awl to locate stud centers on a wall. A cutout is shown for reference.

2.5 Align the arrows on the Wall Plate {32} pointing upward.

Center and level the plate above the mantle and position the height using the table in STEP 2.2. Mark the 4 spots for lag bolts directly on center of the studs.

Diagram Description: Shows leveling the wall plate {32} on the wall and marking the lag bolt hole locations. Includes a note about minimum height from STEP 2.2.

2.6 Pre-drill the 4 holes with 7/32" drill bit to a depth of 2.5 inches (65mm) including wall covering.

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

Diagram Description: Shows drilling pilot holes into the wall studs.

2.7 If necessary, move Wall Plates to clear an outlet.

If a Wall Plate installation is impeded by an electrical outlet (or other) and professionally relocating the outlet is impossible, try one of these two options: Move Wall Plates up or down to clear the outlet. As long as you don't place the LOWER Wall Plate below the Minimum Distance (Step 2.2) MantelMount will clear your mantel properly.

Simply move the Wall Plates up or down enough to clear the outlet, leaving them as close as possible to the originally planned vertical positions.

IMPORTANT: You must now move the Vertical Braces {31} on the back of the TV using the same number of inches used to move the Wall Plates (e.g., move the Vertical Braces down 2" if the Wall Plates were moved down by 2"). The bottom of the Vertical Braces must remain between 3 to 10 inches from the bottom of the TV.

OPTIONAL: If you prefer to drill an access hole in your wall plate cover, the outlet may be placed within the footprint of the wall plate.

NOTE: If outlet is directly behind the Lifting Arm, the only solution is to move the Wall Plates up.

Diagram Description: Shows a 'BEFORE' image of a wall plate blocked by an outlet and an 'AFTER' image with the wall plate moved down. Another 'BEFORE' and 'AFTER' pair shows the wall plate moved up to clear the lifting arm.

Optional Step: Attaching the MM815 Lifting Arm into the RB100 Recess Box Kit

The RB100 Recess Box provides a flush TV-to-wall storage by allowing the MantelMount center arm to fold into the wall when the TV is in the raised position. If installing the MM815 with an RB100, refer to your RB100 manual height chart for proper mounting location.

NOTE: This process will require the use of four {14} M8x16 screws from your mount parts package.

2.8 Insert MM815 Lifting arm into the RB100 Recessed box making sure to align the screw holes on the lifting arm to the screw holes on the RB100 as indicated.

Diagram Description: Shows inserting the MM815 Lifting Arm into the RB100 Recessed Box, aligning screw holes, and indicating screws {14}.

2.9 Rest base of lifting arm on the M6 cap screws. Once all 4 holes are aligned, insert M8x16 screws into holes 1 and 2 and tighten them using allen wrench.

2.10 Connect MM815 lifting arm to power supply and use remote to lower lifting arm to expose holes 3 and 4. Gently push lifting arm up and back to secure wall bracket to back of RB100. Insert M8x16 screws into holes 3 and 4 and tighten using allen wrench. Tighten all four screws then continue with the next step of the installation.

Diagram Description: Shows securing the lifting arm to the wall bracket within the recess box using screws {14}.

STEP 3: Attach Mount to Wall

3.1 Attach the Wall Plate {32} with arrows up, using Lag Bolts {17} and Washers {11} directly into the centers of the studs With 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.

Diagram Description: Shows attaching the wall plate {32} to the wall studs using lag bolts {17} and washers {11}.

3.2 Insert bottom tabs of Lifting Mechanism {35} into the slots of 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 Lifting Mechanism {35} until Screws {14} are installed.

Diagram Description: Shows attaching the lifting mechanism {35} to the wall plate {32} using screws {14}.

Diagram Description: Shows the sequence of button presses on the remote for System Reset: SET, RUN, SET (press and hold).

3.5 Programming Bottom Stop Limit Position

Warning: Damage will occur If the Mount can drive down into something, the bottom stop needs to be set. If the mount would hit the Mantel or some other object in the bottom position. You can easily reduce the bottom most (⬇️) position so that the mount cannot move past that point.

Drive mount to the desired Bottom-most Position by holding ⬇️.
Do NOT allow the mount to run into anything.
Press [SET].
Press [RUN].
Press/Hold [SET] for 4 to 8 Seconds.
Check it was correctly done by trying to move the mount down farther.

Note: To delete the bottom stop follow steps 3 to 6 but hold the set button for more than 10 seconds in step 5.

Diagram Description: Shows the remote buttons used for programming the bottom stop limit (⬇️, [SET], [RUN]). A visual warning icon is present.

3.6 Swivel Safety Clutch

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 the swivel will not work as expected. The swivel needs to be recalibrated right away to avoid damage.

To recalibrate Auto-move the mount to the top position:

Press [RUN]
Press ⬆️ within 3 seconds

The mount will automatically move to the top position and recalibrate. You can also run Reset Function to recalibrate.

Note: If clutch is engaged the mount may swivel a little when coming down, to fix this; manually center mount at zero degree swivel by rotating TV with hands and over-riding clutch. Mount is at zero degrees swivel after you recalibrate (drive the mount to the top position), then move the mount straight down.

Diagram Description: Shows the remote buttons used for recalibration ([RUN], ⬆️).

3.7 Attach the TV Brace {33} to the lifting arm {35}.

Manually Swiveling the Swivel Plate will make accessing the screw holes easier. Level the TV Brace and tighten the 4 screws {15}.

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

Diagram Description: Shows attaching the TV brace {33} to the lifting arm {35} using screws {15}.

STEP 4: Attach TV to Mount

NOTE: These Next Steps Will Require Two People ?

4.1 WARNING!

Do Not put hands into 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. The Mount will keep driving until someone pushes another button on the remote to stop it. When working on the mount unplug the power.

Never allow small children to play around or operate the MantelMount. Property damage or personal injury can occur.

Diagram Description: Safety warnings with icons depicting pinching hazard and children playing near the mount.

4.2 This step requires two people.

Carefully hang the Television onto the TV Brace making sure that both hooks on the Vertical Braces {31} engage the TV Brace {33}.

Diagram Description: Shows two people carefully hanging a TV onto the TV brace {33} which is attached to the vertical braces {31}.

4.3 Center the TV on the TV Frame and check it with a level.

Carefully slide the TV sideways, if required, until it is balanced and horizontal, up to a MAXIMUM OF 2 INCHES left or right. The TV would only need to be moved off-center if it has an unbalanced weight. These are usually older, heavier TVs. If the TV needs to be moved sideways and is visually too much off-center above the mantel, remove the TV and relocate the Wall Plate {32} an equal distance but in the opposite direction of the TV to compensate.

Diagram Description: Shows a TV centered on the mount, with arrows indicating a maximum sideways adjustment of 2 inches.

4.4 Install 4 Screws {15} through the TV Brace {33} and into the Vertical Braces {31}.

Diagram Description: Shows securing the TV brace {33} to the vertical braces {31} with screws {15}.

4.5 Attach cable ties to lower arm.

Shown below is the easiest way to attach cables. Use the included Cable Ties {24} to attach cables so they attach to the underside of the Lower Arm, making a gentle loop. Cables should be long enough to accommodate the extension and swivel of MantelMount. Check all ranges of motion before tightening the Cable Ties.

Diagram Description: Shows attaching cable ties {24} to the lower arm of the mount to manage cables.

4.6 Attach the electrical and signal cables to the TV.

Run signal cables through open loop. Give each segment of the cables extra length so that they are not stressed or kinked when the mount moves. Ensure that cables do not get pinched within the Lifting Arm when the TV is raised.

Reference Only: This is one possible configuration for the signal cables. Each segment of the cables has extra length so that the cables are not stressed or kinked when the mount is moved.

Diagram Description: Illustrates a recommended routing for electrical and signal cables, showing them running through a loop and having sufficient slack.

STEP 5: Make Final Adjustments

Diagram Description: An overview diagram showing the TV mount with labels pointing to different adjustment areas: Centering Cam, Swivel Hardstop, Top Tilt Adjust, Post-Leveling, Bottom Tilt Adjust.

5.1 Programming Left/Right Stop Limit 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.

Mount Space Issues

Issue: The wall covering is made of brick or stone.
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 concrete/masonry professional for this type of installation is recommended. Please contact Customer Support for guidance before attempting installation.
Issue: The drywall/stucco wall covering is thicker than 5/8".
Solution: MantelMount recommends adding more support so mount can attach to the equivalent of 2 studs.
Issue: A single wood stud is centered on my wall.
Solution: MantelMount recommends adding more support so 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 within 3 seconds allow Mount to move all of the way to the top position. Mount should be recalibrated. You can also run Reset Function to recalibrate. 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 the swivel will not work as expected. The swivel needs to be recalibrated right away to avoid damage. To recalibrate Auto-move the mount to the top position.
Issue: TV isn't vertical in out and bottom positions.
Solution: See step 5.4 to adjust the Bottom/Out Position tilt.

Issue: Mount does not move.
Solution: There are a few things to try: 1. Run System Reset, see page 5. 2. Check that power is getting to the mount by making sure there is a green light shining on the plug. 3. Replace the CR2032 battery in the remote. 4. Check that the wires in the mount are plugged in and not damaged. 5. Pair the RF remote, see Step 3.3. 6. Maybe the Bottom Limit got set too high, clear the Bottom Travel Limit, see Page 5. Warning: The mount can now travel all of 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 mount at zero degree swivel by rotating TV with hands and over-riding clutch. Mount is at zero degrees swivel after you recalibrate (drive the mount to the top position), then move the mount straight down.

Product Dimensions Summary

Diagram Description: A technical drawing of the MantelMount MM815 showing key dimensions: Width (37.5"), Height (14.0"), Maximum Drop (26"), Thickness (5.1"), Bottom Clearance (15"), Max Clearance (18"). It also indicates the tilt behavior as the mount lowers.

MantelMount has three different adjustments that must be made after the installation is complete in order to operate properly.

The bottom travel stop is adjusted with the remote control.
The Centering Cams automatically swivel the TV to center while raising to avoid permanent obstacles.
The side-to-side swivel stops are adjusted via remote control and with two screws so that the TV does not swivel into the mantel.
