Choosing the Right Size

Setup and Installation
Proper installation is crucial for optimal performance of your LONTAN drawer slides. Follow these steps carefully:
- Separate the Slides: The drawer slides consist of three parts. Fully extend the slide and press the black release lever (nylon detachable snap) to separate the inner slide member from the main assembly.
- Mount Cabinet Member: Attach the larger, outer slide member to the cabinet side. Ensure it is level and parallel to the floor. Use the provided screws and pre-drill pilot holes if necessary.
- Mount Drawer Member: Attach the inner slide member to the side of your drawer. Ensure it is flush with the front edge of the drawer.
- Insert Drawer: Align the inner slide member on the drawer with the cabinet slide member. Gently push the drawer into the cabinet until the slides click into place.
- Test Functionality: Open and close the drawer several times to ensure smooth operation and proper soft-close engagement.

For framed cabinets, rear mounting brackets (sold separately) may be required to ensure proper installation and alignment. For frameless cabinets, direct side mounting is typically sufficient.

Operating Instructions
LONTAN Soft Close Drawer Slides are designed for smooth and quiet operation. To open a drawer, simply pull it out. To close, gently push the drawer until the soft-close mechanism engages. The hydraulic damper will then take over, slowly and silently pulling the drawer shut.

Maintenance
LONTAN drawer slides require minimal maintenance due to their durable construction and sealed ball bearings. However, periodic checks can help ensure continued smooth operation:
- Cleaning: Wipe down the slides with a clean, damp cloth to remove dust and debris. Avoid harsh chemicals or abrasive cleaners.
- Lubrication: The ball bearings are pre-lubricated. If you notice any stiffness over time, a small amount of silicone-based lubricant can be applied to the ball bearings. Avoid oil-based lubricants as they can attract dust.
- Check Fasteners: Periodically check that all mounting screws are tight. Loose screws can affect the alignment and performance of the slides.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drawer does not close completely or slams. | Soft-close mechanism not engaging or damaged; obstruction in slide path. | Check for obstructions. Ensure the soft-close mechanism is clean and free of debris. If damaged, contact customer support for replacement. |
| Drawer is stiff or hard to open/close. | Misalignment of slides; insufficient lubrication; debris in ball bearings. | Verify slides are level and parallel. Clean ball bearings and apply a small amount of silicone lubricant. Check for loose mounting screws. |
