The Webasto Marine Roof 50 Series is an electrically operated sliding roof designed for ventilation purposes in marine environments. This manual provides comprehensive instructions for its safe and correct operation, maintenance, and troubleshooting.

Function Description

The Marine Roof 50 Series is an electrically powered sliding roof system that allows for controlled ventilation on boats. It consists of a glass panel that slides along guides and rails, driven by an electric motor. The roof is operated via a control switch, which includes "Open" and "Close" buttons. When the "Open" button is pressed and held, the roof will continue to open until the button is released or until it is fully open. Similarly, pressing and holding the "Close" button will cause the roof to close until the button is released or it is fully closed.

The system is designed for easy installation in various boats and is suitable for fitting in area III and usage for boats with design-category A according to ISO 12216. It incorporates safety features and operational guidelines to ensure reliable performance in marine conditions.

In the event of a power failure or malfunction, the roof can be operated manually using an emergency key. This manual operation involves removing a motor cover, inserting the emergency key into a designated slot on the motor, and turning the key to either open or close the roof. After manual operation, the control system must be reinitialised to restore normal electrical functionality.

Usage Features

The Marine Roof 50 Series offers several usage features designed for convenience and safety:

Electric Operation: The primary mode of operation is electric, allowing for effortless opening and closing of the roof via a control switch. This provides quick and convenient ventilation control.
Continuous Opening/Closing: The roof can be opened or closed continuously by holding down the respective button, or it can be stopped at any desired intermediate position by releasing the button.
Emergency Manual Operation: An emergency key is provided for manual operation, ensuring that the roof can always be opened or closed even if the electrical system fails. This is a critical safety feature for marine applications.
Reinitialisation Procedure: After manual operation or in case of certain system issues, a reinitialisation procedure is required to recalibrate the control system. This involves a specific sequence of pressing and holding the "Close" button to ensure the system recognizes the roof's fully closed position and restores smooth electrical operation.
Safety Guidelines: The manual emphasizes several safety instructions for users, including closing the roof at high speeds (above 30 kts), in rough sea states (more than 1 m), or high wind speeds (more than 16 kts). Users are also warned to keep body parts and obstructions away from the opening during operation to prevent injury. The roof should not be used as an escape hatch, and an alternative escape route must always be accessible. It is also advised to close the roof in case of rain or snow to prevent water ingress.
Water Ingress Prevention: Before opening the roof, users are advised to remove any residual water from the glass panel to prevent water from entering the cabin.

Maintenance Features

Proper maintenance is crucial for the longevity and smooth operation of the Marine Roof 50 Series. The manual outlines a clear set of maintenance procedures:

Regular Cleaning: The roof should be cleaned regularly. The glass panel should be washed with clean water and a soft cloth, chamois, or sponge. It is important never to rub a dry surface and to avoid abrasive or harsh cleaning solutions such as turpentine or mineral spirits, as these can damage the glass.
General Roof Cleaning: The remainder of the roof should be washed with warm water using a professional marine-grade cleaning product, followed by rinsing with clean water.
Lubrication of Guides and Rails: To ensure smooth sliding, a thin layer of Isoflex® Topas L32 grease should be applied to the inside of the guides and rails. This specialized grease is available through Webasto.
Prohibited Cleaning Agents: The manual explicitly warns against using certain types of cleaning products, including:
- Alkaline products containing sodium solutions.
- Acid products like muriatic acid or those containing phosphorus.
- Steel wool, abrasives, or sandpaper.
- Alkaline-containing cleaning products for glass, as these can corrode aluminum components.
Troubleshooting Guide: A troubleshooting section is provided to help users diagnose and resolve common issues. For example, if the roof experiences poor opening/tilting or poor movement, the suggested solutions involve cleaning the seal with a mild detergent or cleaning and greasing the guides and rails. If these steps do not resolve the issue, users are advised to contact their boat manufacturer for further maintenance or repair.
Professional Installation and Repair: The warranty and liability statement highlights the importance of professional installation and repairs carried out by a Webasto service workshop. Using non-genuine parts, unauthorized conversions, or mechanical damage due to improper use or non-compliance with inspection and maintenance instructions can void the warranty.
