Installation Steps
- Locate Wall Studs: Use a stud finder to locate the center of a wooden wall stud. Mark the desired mounting height. For concrete or brick walls, use appropriate anchors (not always included, verify kit contents).
- Position Wall Plate: Hold the wall mount assembly against the wall at the marked location. Use the integrated bubble level to ensure it is perfectly horizontal. Mark the drilling points through the mounting holes.
- Drill Pilot Holes: Drill pilot holes at the marked locations. Ensure the drill bit size matches the recommended size for your wall type and mounting hardware.
- Secure Wall Mount: Attach the wall mount assembly to the wall using the provided lag bolts and washers. Tighten securely, but do not overtighten.
- Attach TV Mounting Plate to TV: Carefully place your TV face down on a soft, clean surface. Attach the TV mounting plate to the back of your television using the appropriate VESA screws and spacers from the hardware kit. Ensure the screws are tightened securely.
- Mount TV to Wall Mount: With assistance, carefully lift the television and align the TV mounting plate with the arm assembly. Secure the TV to the arm assembly according to the specific design of the mount, typically involving hooks and safety screws.

4. Operating Instructions
The Manhattan 423670 mount allows for flexible positioning of your flat-panel TV.
Adjusting Tilt
To adjust the vertical tilt angle (up or down), loosen the tilt adjustment knobs or bolts located on the TV mounting plate. Adjust the screen to the desired angle (up to 15 degrees), then securely tighten the knobs/bolts to fix the position.
Adjusting Swivel and Extension
The double-arm design allows for horizontal swivel (left or right) and extension from the wall. Gently push or pull the television to achieve the desired viewing angle and distance from the wall. The mount supports 360-degree swivel at certain pivot points. Ensure all connections remain secure during adjustment.
Cable Management
Utilize the built-in cable management system (e.g., clips or channels) on the arms to route and secure cables. This helps maintain a tidy appearance and prevents cables from being pinched or damaged during adjustments.
5. Maintenance
Regular maintenance ensures the longevity and safe operation of your TV mount.
- Cleaning: Wipe the mount with a soft, dry cloth. Avoid abrasive cleaners or solvents that could damage the finish.
- Periodic Checks: Periodically check all screws and bolts to ensure they remain tight. Over time, vibrations or frequent adjustments can cause fasteners to loosen.
- Lubrication: The articulating joints are designed for smooth movement. If movement becomes stiff, a small amount of silicone-based lubricant can be applied to the pivot points, avoiding contact with electrical components.
6. Troubleshooting
If you encounter issues with your Manhattan 423670 TV mount, refer to the following common problems and solutions:
- Mount is not level:
- Ensure the wall plate was installed level using the integrated bubble level. If not, minor adjustments may be possible by slightly loosening and re-tightening wall screws, or re-drilling if necessary.
- Check if the TV is securely attached to the mounting plate and not skewed.
- TV sags or tilts unexpectedly:
- Verify that the TV's weight does not exceed the mount's maximum capacity.
- Ensure all tilt adjustment knobs/bolts are securely tightened.
- Check that the VESA screws attaching the TV to the plate are tight.
- Difficulty adjusting swivel or extension:
- The joints may be stiff. Apply a small amount of silicone lubricant to the pivot points.
- Ensure no cables are snagged or preventing movement.
- Mount feels unstable:
- Immediately remove the TV. Re-check all wall mounting screws and ensure they are securely fastened into a solid wall structure (e.g., center of a stud).
- Verify that the wall material is appropriate for the chosen mounting hardware.
If problems persist, contact Manhattan customer support.
