Installation Guide
Proper installation is key to the smooth and reliable operation of your LONTAN Soft Close Drawer Slides. Follow these steps carefully:
1. Choose the Correct Size
Ensure the selected slide length matches your drawer depth. It is recommended to reserve 0.5 inches of space for mounting on both sides of the drawer. These slides are suitable for drawer depths ranging from 10 to 24 inches.

2. Separate the Slide Components
Each drawer slide consists of two main parts: the cabinet member and the drawer member. Extend the slide fully and press the release lever (typically black) to separate the inner drawer member from the outer cabinet member.

3. Mount the Cabinet Member
Attach the larger cabinet member to the inside of your cabinet. Ensure the slide is level and parallel to the cabinet opening. Use the provided screws to secure it firmly. For framed cabinets, rear mounting brackets (sold separately) may be required to ensure proper alignment and support.

Important: Make sure the two slides are placed in parallel to ensure smooth drawer operation.
4. Mount the Drawer Member
Attach the thinner drawer member to the side of your drawer box. Ensure it is flush with the front edge of the drawer and securely fastened with screws. The fixed hole positions simplify the workflow of installation and adjustment.

5. Insert the Drawer
Align the drawer member with the cabinet member and gently push the drawer into the cabinet until it clicks into place. Ensure the inner and outer rails are at the same level for correct insertion.

Usage and Maintenance
Operating the Soft Close Feature
The soft close feature engages automatically when the drawer is pushed gently towards the closed position. The hydraulic damper will slow down the drawer's movement, ensuring a quiet and smooth closure. Avoid forcing the drawer shut, as this can bypass or damage the soft close mechanism.

Maintenance and Cleaning
LONTAN drawer slides are designed for easy maintenance. If cleaning is required, you can utilize the double disassembly clip to remove the drawer from the cabinet. Wipe the slides with a damp cloth to remove dust or debris. Avoid using abrasive cleaners or harsh chemicals that could damage the zinc-plated finish or the internal mechanisms. Regular light lubrication (e.g., with silicone spray) can help maintain optimal smoothness, especially in high-use applications.

Troubleshooting
If you encounter any issues with your LONTAN Soft Close Drawer Slides, please refer to the common problems and solutions below:
- Drawer Not Closing Fully or Sticking:
- Check for obstructions: Ensure no items within the drawer or cabinet are blocking the slide's path.
- Verify alignment: Improper alignment during installation can cause sticking. Ensure both slides are perfectly level and parallel.
- Overload: Confirm the drawer's weight does not exceed the 100 LB capacity. Excessive weight can hinder the soft close mechanism.
- Debris: Clean the ball bearings and rails to remove any accumulated dust or debris that might impede movement.
- Drawer is Noisy or Rattling:
- Loose screws: Check all mounting screws on both the drawer and cabinet members and tighten if necessary.
- Lubrication: Apply a small amount of silicone lubricant to the ball bearings and rails to reduce friction and noise.
- Damage: Inspect the slides for any visible damage or bending. If damaged, replacement may be necessary.
- Drawer Drops or Detaches:
- Improper installation: Ensure the double anti-drop function is correctly engaged and the slides are securely mounted.
- Damage to anti-drop mechanism: Inspect the anti-drop clips for any breakage or wear.
