Installation Steps:


Determine Handing and Jam Type: Begin by identifying the handing of the door (i.e., which direction it opens) and the type of jam it has. Refer to the manufacturer's instructions for guidance on determining handing and selecting the appropriate mounting option.

Choose Mounting Option: Based on the door's configuration and the recommendations provided, choose the suitable mounting option for the LCN door closer. Options typically include standard mount, top jam mount, or parallel mount.

Adjust Dimensions: Measure and mark the placement of the mounting brackets according to the manufacturer's specifications. Ensure proper clearance and alignment for the door closer and arm assembly.

Pre-drill Holes: Use a drill to pre-drill holes for mounting brackets and screws. This ensures precise placement and prevents damage to the door or frame during installation.

Attach Brackets and Arm Assembly: Secure the mounting brackets to the door and frame using appropriate screws. Install the arm assembly according to the chosen mounting option, ensuring proper alignment and tension.

Adjust Speed Settings: Utilize the provided adjustment features on the LCN door closer to adjust swing speed, latching speed, and back check as needed. Follow the manufacturer's instructions for proper adjustment techniques.

Test Operation: After installation and adjustments are complete, test the operation of the LCN door closer to ensure smooth and controlled door closing. Make any final adjustments as necessary to achieve the desired performance.

Types of LCN Door Closers:

LCN offers a variety of door closers to suit different applications and requirements. Some common types include:


Surface-Mounted Closers: These closers are installed on the surface of the door and frame, making them suitable for most standard door configurations.

Concealed Closers: Concealed within the door or frame, these closers offer a sleek and unobtrusive appearance while providing reliable door control.

Overhead Closers: Mounted on the top of the door, overhead closers are ideal for heavy-duty doors and high-traffic areas.

Maintenance Tips:

To ensure optimal performance and longevity of LCN door closers, regular maintenance is essential. Here are some maintenance tips to follow:

Keep the Closer Clean: Regularly clean the exterior surfaces of the closer to remove dirt, dust, and debris that can affect its operation.

Lubricate Moving Parts: Apply lubricant to the moving parts of the closer, such as hinges and pivot points, to reduce friction and prolong the lifespan of the unit.

Check for Loose Screws: Periodically inspect the mounting screws and hardware for any signs of looseness or damage. Tighten or replace as needed to maintain stability and security.

Test Operation: Test the operation of the door closer regularly to ensure it closes smoothly and securely. Make any adjustments or repairs promptly if issues are detected.

Schedule Professional Inspections: Consider scheduling regular inspections by a qualified technician to assess the condition of the door closer and address any potential issues proactively.

Monitor for Wear and Tear: Regularly inspect the components of the LCN door closer for signs of wear, such as worn-out seals, leaking hydraulic fluid, or damaged mounting brackets. Addressing these issues promptly can prevent further damage and ensure the continued functionality of the door closer.

Adjust Spring Power: Periodically check the spring power adjustment of the door closer to ensure that it is appropriately calibrated for the weight and size of the door. Adjustments may be necessary over time due to changes in environmental conditions or door usage.

Conduct Seasonal Checks: As environmental conditions change throughout the year, such as temperature fluctuations and humidity levels, it's essential to conduct seasonal checks on the LCN door closer. Make any necessary adjustments to compensate for these changes and maintain consistent door operation.

Train Personnel: Educate building occupants and maintenance staff on the proper use and care of doors equipped with LCN door closers. Provide guidance on how to avoid excessive force when opening or closing doors, as well as how to report any issues or malfunctions promptly.

Keep Records: Maintain detailed records of maintenance activities, including inspection dates, adjustments made, and any repairs performed on the LCN door closer. This documentation can help track the performance and condition of the door closer over time, facilitating proactive maintenance and troubleshooting.

By following these additional maintenance tips and understanding the various types of LCN door closers available, you can ensure the reliable and efficient operation of doors in commercial settings. Regular maintenance and proper care not only extend the lifespan of LCN door closers but also contribute to the overall safety and security of the building environment.
