Step by step

  1. 2 min

    Calculate the exact mounting height

    Determine the optimal viewing center, typically 42 inches from the floor to the center of the screen. Mark this height on the wall. Subtract the distance from the TV mounting holes to the center of the screen to identify the precise mounting plate location.

    Note: Always align your mounting plate with the studs for structural integrity.

    Identify the recessed power location

    Measure the location of your TV's power input port on the rear chassis. Choose an outlet position that falls within the recessed area of the mount to ensure the TV sits flush against the wall. Ensure this position avoids existing wall studs.

    Note: Use a stud finder to map out a clear vertical path for cables.
  3. 2 min

    Check for internal wall obstructions

    Use a non-contact voltage tester around your intended cut-out area to ensure no electrical wires are present behind the drywall. Verify the depth of the wall cavity to accommodate the recessed outlet housing.

    Note: Turn off the main circuit breaker if you suspect existing wiring in the wall.
  4. 15 min

    Install the recessed power kit

    Trace the template provided with your recessed power kit onto the wall at your calculated position. Use a drywall saw to cut the hole, then route your power extension cable and AV cables through the cavity to the base of the wall.

    Note: Ensure your AV cables are CL3-rated for in-wall use to meet building codes.

    Secure the power and signal cables

    Connect the male end of the extension power cord to your source outlet near the floor. Route the female end through the wall to the recessed outlet box. Secure the box to the drywall and snap the trim plate into place.

    Note: Use cable ties to bundle excess length behind the mount.

    Test the electrical connection

    Plug the television into the newly installed recessed outlet. Switch on the circuit breaker and use the non-contact voltage tester to verify power is flowing correctly. Power on the display to confirm connection stability before finalizing the mount.

    Note: Check that the television power cord does not kink when the mount is retracted.
