5. Setup and Installation
This section provides a general overview of the installation process. For detailed, step-by-step instructions, always refer to the specific installation guide provided in your product packaging. Professional installation is highly recommended.
- Preparation: Ensure the shower base or curb is level and clean. Unpack all components and inspect for damage.
- Measure and Mark: Carefully measure and mark the positions for the wall profiles on your bathroom wall, ensuring they are plumb and align with your existing shower door frame.
- Install Wall Profiles: Drill pilot holes and secure the wall profiles to the wall using the provided fasteners. Ensure a secure and watertight seal.
- Install Glass Panel: Carefully lift and insert the glass return panel into the installed wall profiles. Ensure the panel is properly seated and level.
- Secure Glass: Secure the glass panel within the profiles using the designated screws or clips, as per the detailed instructions.
- Apply Sealant: Apply a continuous bead of 100% silicone sealant along all exterior joints where the glass meets the wall profiles and the shower base/curb. Allow adequate curing time before using the shower.
- Final Adjustments: Make any necessary final adjustments to ensure smooth operation and a watertight enclosure.
6. Operating the Return Panel
The MAAX Uptown Frameless Return Panel is a fixed glass panel designed to create a corner shower enclosure when paired with a compatible MAAX Uptown shower door. It does not have moving parts for operation. Its function is to provide a stationary glass wall, allowing the adjacent shower door to operate as intended (e.g., sliding, pivoting, or bypassing).
7. Maintenance
Regular cleaning and maintenance will preserve the appearance and longevity of your MAAX Uptown Frameless Return Panel.
- Glass Cleaning: The glass features Lotus easy-clean protection. For daily cleaning, use a soft cloth or squeegee after each use to remove water spots. For deeper cleaning, use a mild, non-abrasive glass cleaner. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the glass coating and finish.
- Trim Cleaning: Clean the matte black trim with a soft, damp cloth and mild soap. Do not use abrasive cleaners or solvents, which can damage the finish.
- Seals: Periodically inspect the seals for wear or damage. Replace them if necessary to maintain a watertight enclosure.
- Ventilation: Ensure proper bathroom ventilation to reduce moisture buildup, which can lead to mold and mildew.
8. Troubleshooting
- Water Leaks:
- Check all silicone sealant lines for gaps or cracks. Reapply silicone if needed.
- Ensure the wall profiles are securely fastened and plumb.
- Verify that the glass panel is properly seated in its channels.
- Glass Stains/Spots:
- Use a squeegee after each use.
- For stubborn spots, use a cleaner specifically designed for shower glass with protective coatings.
- Loose Panel:
- Check all screws and fasteners securing the wall profiles and glass panel. Tighten if loose, but do not overtighten.
