5. Setup and Installation
Follow these steps for proper installation of your Blum Tandem drawer slides:
- Prepare the Cabinet: Ensure the cabinet opening is square and the interior depth meets the minimum requirement. For 18" drawers, a minimum interior depth of 18-3/4" is required. For inset applications, increase the minimum interior depth by the thickness of the drawer front.
- Install Cabinet Members: Attach the cabinet members of the slides to the interior sides of the cabinet. Use the provided screws. The slides are designed for side-mount to the cabinet. Rear-mount brackets (sold separately, search for "Blum Rear Mount") may be used for additional support or specific cabinet designs.
- Prepare the Drawer Box: The drawer box should be constructed for undermount slides, typically with a 3/4" side thickness. Ensure the bottom of the drawer box is recessed to accommodate the slides.
- Attach Drawer Members: Secure the drawer members of the slides to the underside of the drawer box.
- Install Locking Devices: Locking devices (sold separately, search for "Blum Locking Device For Tandem Drawer Slides") are required to secure the drawer box to the slides. Attach these to the front underside of the drawer box according to their specific instructions.
- Insert Drawer: Carefully align the drawer box with the cabinet slides and push the drawer in until the locking devices engage with the slides. You should hear a click.
- Adjustments: Blum Tandem slides often feature adjustment mechanisms for height, tilt, and side-to-side alignment. Refer to the specific locking device instructions for detailed adjustment procedures to achieve perfect drawer alignment.
Note: For optimal performance and stability, ensure all screws are tightened appropriately, but do not overtighten.
6. Operating Instructions
The Blum Tandem Premium Undermount Drawer Slides are designed for smooth and quiet operation with an integrated soft-close feature.
- Opening the Drawer: Pull the drawer handle to open. The full extension feature allows the drawer to extend completely out of the cabinet, providing full access to its contents.
- Closing the Drawer: Gently push the drawer closed. The integrated Blumotion soft-close mechanism will engage in the final inches of travel, slowing the drawer down and pulling it silently and softly into the closed position. Avoid slamming the drawer, as the soft-close mechanism is designed to handle gentle closing.
- Removing the Drawer: To remove the drawer from the cabinet, locate the release levers on the locking devices (typically one on each side, underneath the drawer). Engage these levers (usually by pushing them up or down, depending on the model) and then pull the drawer straight out.
7. Maintenance
Blum Tandem slides are engineered for durability and require minimal maintenance.
- Cleaning: Wipe the slide surfaces with a clean, damp cloth to remove dust and debris. Avoid using abrasive cleaners or solvents, as these can damage the finish or internal components.
- Lubrication: The slides are pre-lubricated and generally do not require additional lubrication under normal household use. If squeaking or stiffness occurs after extended use, a small amount of silicone-based lubricant can be applied to the moving parts, avoiding the soft-close mechanism.
- Inspection: Periodically check all mounting screws for tightness. Retighten if necessary. Inspect the slides for any signs of wear or damage.
