The MantelMount MM340 is a pull-down television mount designed for installation above fireplaces and in other locations where a traditional fixed mount is unsuitable. This article details the installation process, specifications, and troubleshooting considerations based on official documentation. The mount is covered by a limited lifetime warranty from MantelMount. Customer support is available at 1.800.897.9755 ext.1 or [email protected].
Before Installation: Requirements and Verification
Prior to beginning installation, several criteria must be met to ensure compatibility and a secure installation. The MM340 is designed for televisions with a diagonal screen size ranging from 44 to 80 inches. The weight capacity of the mount is between 20 and 90 pounds, including any attached sound bar (accessory required for sound bar mounting, available at mantelmount.com). The VESA mounting pattern must be within 200-700mm in width and 100-500mm in height.
Installation requires wood studs, with a maximum spacing of 32 inches apart. Wall covering thickness should not exceed 5/8 of an inch. The maximum mantel depth supported is 18 inches. It is crucial to verify that all parts are included before commencing installation.
Installation Procedure Overview
The installation of the MM340 involves several steps. Two people are required for certain parts of the installation process. Installation tips and videos are available at http://mantelmount.com/install-tips. The documentation emphasizes the importance of carefully reading the entire manual before starting.
The process begins with mounting the wall plate. If the desired position requires accessing a blocked hole in the wall plate, a Safety Bolt must be used to access it, followed by removal and reinstallation of the Lag Bolts. If an electrical outlet is located directly behind the lifting arm, the wall plates may need to be moved upwards.
Braces are attached to the television, ensuring they are parallel to the television screen. Extenders are installed so that the handles sit 1" (25mm) below the TV or sound bar. If a higher TV position is desired, for increased space above the mantel, the installation process continues to a specific step.
Component Assembly and Adjustment
After mounting the wall plate and attaching the braces to the television, the television is carefully lifted and attached to the mount. The Safety Bolt and Safety Nut are essential for removing the TV in the future. It is critical to avoid releasing the handle before the TV mount is fully upright, as allowing it to slam closed can damage the television.
Cable management is an important consideration. Cables should have extra length to prevent stress or kinking during movement. Cables must also be routed to avoid being pinched behind the tilting mechanism when the mount is raised.
Post-Installation Adjustments and Safety Features
Following the initial installation, adjustments are necessary to ensure proper lifting performance. The Tension Bolt controls the lifting force and should be adjusted clockwise to increase the force if the TV is tilting forward when in the UP position. Caution is advised: the Tension Bolt should not be adjusted all the way to the bottom, as this will compromise the functionality of the Safety Bolt.
Post-leveling adjustments may be required. A level should be placed on top of the TV while it is in the UP position to verify that it is level. If adjustments are needed, the documentation directs users to Step 5.6 for instructions.
The MM340 incorporates several safety features. A Safety Bolt is used to access blocked wall plate holes and is crucial for safe removal of the television. The Lifting Arm can cause bodily injury if hands are placed inside without the Safety Bolt and Safety Nut installed.
Troubleshooting Common Issues
The documentation provides troubleshooting guidance for common issues. If the TV is tilting forward when in the UP position, the Lifting Force may not be set tightly enough. Adjusting the Tension Bolt clockwise can resolve this issue.
If installation is attempted on a brick or stone wall, concrete anchors of the same size as the Lag Bolts may be used, provided the brick/stone is firm and at least 1.5 inches deep. However, MantelMount strongly recommends consulting a concrete and masonry professional for uneven stone surfaces.
If the TV is not level in the UP position but is level in the DOWN position, post-leveling adjustments are required. The documentation refers users to Step 5.6 for detailed instructions.
