Setup and Installation
Important: Professional installation is recommended for this product. Ensure you have all necessary tools and safety equipment before beginning. A minimum threshold depth of 1 1/2 inches is required for proper installation.
Key Installation Considerations:
- Wall Preparation: Aluminum water guards are designed to accommodate up to 1/4 inch for out-of-plumb (uneven) walls. Ensure your shower enclosure walls are as plumb as possible for optimal installation and sealing.
- Width Adjustment: The top and bottom guiderails can be trimmed up to 4 inches to fit your specific shower opening width. Measure carefully before cutting.
- Reversibility: The double sliding bypass configuration allows for reversible installation, meaning the door can be set up to open from either the left or right side. Plan your preferred opening direction before assembly.

Operating Instructions
The DreamLine Alliance Pro LT shower door features a double sliding bypass design, allowing for flexible entry and exit from your shower enclosure.
Opening and Closing the Doors:
- Grasp the integrated towel bar or the edge of the glass panel.
- Gently slide the desired glass panel along the top and bottom guiderails. The smooth gliding rollers ensure quiet and effortless movement.
- To close, slide the panel back until it meets the stationary panel or the wall jamb, ensuring a secure closure.
Both panels can slide independently, providing versatility in how you access your shower.

Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your DreamLine shower door.
Glass Cleaning:
- Use a soft cloth or sponge with a non-abrasive glass cleaner.
- Avoid abrasive cleaners, scouring pads, or harsh chemicals as they can damage the glass or hardware finish.
- For best results, wipe down the glass after each use to prevent water spots and soap scum buildup.
Hardware Cleaning (Oil Rubbed Bronze):
- Clean the Oil Rubbed Bronze finish with a soft, damp cloth.
- Do not use abrasive cleaners, ammonia-based products, or harsh chemicals, as these can strip the finish.
- Dry thoroughly after cleaning to prevent water spots.
Roller and Track Maintenance:
- Periodically inspect the rollers and tracks for any debris or buildup.
- Clean the tracks with a small brush or vacuum to remove any obstructions that might hinder smooth operation.
- Avoid applying lubricants unless specifically recommended by DreamLine, as some lubricants can attract dirt.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door does not slide smoothly. | Debris in tracks, worn rollers, misaligned panels. | Clean tracks thoroughly. Inspect rollers for damage and replace if necessary. Check panel alignment and adjust according to installation instructions. |
| Water leaks from the bottom or sides of the door. | Improper sealing, worn seals/sweeps, out-of-plumb walls. | Ensure all seals and sweeps are correctly installed and in good condition. Re-apply silicone sealant if necessary. Verify walls are within the acceptable out-of-plumb tolerance. |
| Door panels do not meet correctly. | Misalignment during installation, shifting of the enclosure. | Review installation instructions for proper panel alignment. Adjust top and bottom guiderails as needed. |
