Setup and Installation
Before beginning installation, ensure you have the necessary tools and a suitable wall box with a hole spacing of 185 mm. The spring of the belt winder is pre-tensioned to simplify belt attachment.
-
Prepare the Wall Opening: Ensure the wall opening for the recessed winder is clean and correctly sized for the unit. The required hole spacing is 185 mm.

- Attach the Roller Shutter Belt: Feed the roller shutter belt (23 mm width) through the winder mechanism. The pre-tensioned spring facilitates this step. Ensure the belt is securely attached to the winder drum.
- Insert the Winder: Carefully insert the belt winder into the wall box. The installation depth is adjustable between 115 mm and 135 mm, allowing for flexibility to match your wall structure.
- Secure the Winder: Fasten the winder securely within the wall box using appropriate screws. Ensure it is flush with the wall surface.
-
Install the Cover Plate (Sold Separately): Once the winder is secured, attach the desired cover plate. These are available separately in various designs and with appropriate hole spacing to complement your living environment.

Operating Instructions
Operating the Schellenberg 50400 Maxi Recessed Belt Winder is straightforward:
- To raise the roller shutter, pull the belt downwards smoothly and evenly.
- To lower the roller shutter, release the belt slowly and allow the winder mechanism to retract the belt, guiding the shutter downwards.
- Avoid sudden jerks or excessive force on the belt, as this can damage the winder mechanism or the roller shutter itself.
Maintenance
The Schellenberg 50400 Maxi Recessed Belt Winder is designed for long-lasting performance with minimal maintenance. Follow these guidelines:
- Cleaning: Periodically wipe the visible parts of the winder and cover plate with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Belt Inspection: Regularly check the roller shutter belt for signs of wear, fraying, or damage. A worn belt should be replaced promptly to ensure safe and smooth operation.
- Mechanism Check: If you notice any unusual resistance or noise during operation, inspect the winder mechanism. Do not attempt to disassemble the spring mechanism unless you are qualified, as it is under tension.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Belt does not retract fully or is loose. | Spring tension is insufficient or belt is too long for the shutter height. | Ensure the belt length is appropriate for your roller shutter. If the spring tension is the issue, professional assistance may be required for adjustment or replacement. |
| Belt is difficult to pull or retracts slowly. | Friction in the winder mechanism or belt guide, or the roller shutter itself is stiff. | Check the belt path for obstructions. Ensure the belt guide is clean. Inspect the roller shutter for issues. |
| Winder does not fit into the wall box. | Incorrect wall box dimensions or hole spacing. | Verify the wall box dimensions and hole spacing (185 mm) against the product specifications. The installation depth is adjustable (115-135 mm). |
