Mounting Options
The Tell 15543 500 Series Door Closer is designed for versatile installation with a Tri-Pack mounting system, supporting three common applications:
- Regular Arm Mount: Closer body mounted on the pull side of the door.
- Top Jamb Mount: Closer body mounted on the push side of the door frame.

Operating
The door closer is designed to control the closing speed of a door, ensuring it closes smoothly and securely. Adjustments can be made to fine-tune the closing and latching speeds.
Adjusting Closing Speed
The main closing speed is typically controlled by a valve located on the closer body. Turning the valve clockwise will decrease the closing speed (slower), and turning it counter-clockwise will increase the closing speed (faster). Make small adjustments and test the door's closing action after each adjustment.
Adjusting Latch Speed
The latching speed, which controls the final few degrees of the door's closing cycle, is controlled by a separate valve. This allows the door to accelerate slightly at the end to ensure the latch engages properly. Adjust this valve similarly to the main closing speed valve, making small increments and testing.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your door closer.
- Periodic Inspection: Annually inspect the closer body, arm assembly, and mounting hardware for any signs of wear, damage, or loose fasteners.
- Cleaning: Wipe the closer body and arm with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or solvents.
- Lubrication: The internal mechanisms are factory-lubricated and sealed. No additional lubrication is typically required. Do not attempt to open the closer body.
- Adjustments: Re-adjust closing and latching speeds as needed due to environmental changes or wear.
Troubleshooting
This section addresses common issues you might encounter with your door closer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Door closes too fast/slow | Closing speed valve incorrectly set. | Adjust the main closing speed valve (refer to 'Adjusting Closing Speed' section). |
| Door does not latch properly | Latching speed valve incorrectly set or door/frame misalignment. | Adjust the latching speed valve. Check door and frame for proper alignment. |
| Door slams shut | Closing and/or latching speed set too fast. | Decrease both closing and latching speeds by turning valves clockwise. |
| Oil leakage from closer body | Damaged seals or internal components. | Discontinue use and contact customer support for replacement or repair. Do not attempt to repair yourself. |
