2. What's in the Box
Verify that all components are present before beginning installation:
- 1460 series hydraulic cylinder
- Hold-open double lever arm
- Parallel arm shoe
- Plastic cylinder cover
- Peel-n-stick installation template
- Fastener pack: thru-bolt with self-reaming and tapping screws
3. Setup and Installation
The LCN 1460 door closer is non-handed, allowing for installation on doors with hinges on either the right or left side. It offers versatile mounting options:
- Regular Mount: On the hinge (pull) side of the door.
- Top Jamb Mount: On the reverse (push) side of the door.
- Parallel Arm Mount: Requires installation on the push side, utilizing the included parallel arm shoe. This configuration allows the double lever arm to occupy the recess of the door frame when at rest, providing a low profile.
Installation Steps:
- Review Instructions: Carefully study the provided instructions and diagrams before beginning.
- Prepare Door and Frame: Use the peel-n-stick installation template to accurately mark drilling locations on the door and frame.
- Mount Cylinder: Secure the hydraulic cylinder to the door or frame using the fasteners from the pack, including thru-bolts with self-reaming and tapping screws.
- Attach Arm: Install the double lever arm according to your chosen mounting configuration (regular, top jamb, or parallel arm with shoe).
- Install Cover: Place the plastic cylinder cover over the hydraulic cylinder.
- Initial Adjustments: Perform initial adjustments for closing force, speed, and backcheck as described in the Operating Instructions section. You will need allen wrenches for speed and force adjustments, and a large open-end wrench for the hold-open position.
Note: Proper installation is crucial for optimal performance and compliance with safety standards. If you are unsure about any step, consult a qualified professional.
4. Operating Instructions and Adjustments
The LCN 1460 door closer allows for precise control over door movement. Adjustments are made using the valves on the hydraulic cylinder.
- Hold-Open Feature: The double lever arm includes a hold-open feature that keeps the door in an open position when engaged. To set or release the hold-open, refer to the specific instructions provided with the closer, typically involving an adjustment on the arm itself using a large open-end wrench.
- Closing Force: Adjusts the spring force required to open the door. This can be set from sizes 1 to 6 to accommodate interior doors up to 60 inches wide or exterior doors up to 48 inches wide, helping to comply with ADA requirements.
- Closing Speed (Sweep): Controls the speed at which the door closes from its fully open position until the last 10 degrees of travel.
- Latch Speed: Regulates the speed of the door for the final 10 degrees of closure, ensuring a secure latch without slamming.
- Backcheck: Provides resistance when the door is opened forcefully, protecting walls and preventing damage from wind gusts.
Always make small adjustments and test the door's operation after each change to achieve the desired closing characteristics.
5. Maintenance
The LCN 1460 door closer is designed for durability and minimal maintenance.
- Regular Inspection: Periodically inspect the door closer and its mounting hardware for any signs of wear, looseness, or damage.
- Cleaning: Keep the closer body and arm clean from dust and debris. Use a soft, damp cloth for cleaning. Avoid abrasive cleaners.
- Hydraulic Fluid: The closer uses all-weather hydraulic fluid, which helps reduce the need for seasonal adjustments. No user-serviceable fluid changes are required.
- Fasteners: Ensure all mounting screws and arm fasteners remain tight. Retighten if necessary.
Do not attempt to disassemble the hydraulic cylinder, as this may void the warranty and compromise the closer's performance.
6. Troubleshooting
If you encounter issues with your LCN 1460 door closer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Door closes too fast or too slow | Improper sweep or latch speed adjustment. | Adjust the sweep and latch speed valves on the hydraulic cylinder. Turn clockwise to slow down, counter-clockwise to speed up. Make small adjustments. |
| Door does not close completely | Insufficient latch speed or closing force; obstruction. | Increase latch speed or closing force. Check for any physical obstructions preventing full closure. |
| Door slams shut | Latch speed set too high. | Decrease the latch speed by turning the valve clockwise. |
| Door is difficult to open | Closing force set too high. | Decrease the closing force. Ensure it still meets ADA requirements if applicable. |
| Missing parts upon unboxing | Packaging error or lost components. | Verify all components against the "What's in the Box" section. Contact LCN customer support for assistance with missing parts. |
If the problem persists after attempting these solutions, contact LCN customer support.
