5. Setup and Installation
5.1. Measurement
Accurate measurement is crucial for proper fit and function. Determine whether you will use an inside mount (within the window frame) or an outside mount (outside the window frame).
- For Inside Mount:
- Measure the exact width of the window frame at the top, middle, and bottom. Use the smallest measurement.
- Subtract 1/4 inch from the measured width for the blind width.
- Measure the exact height of the window frame. The blind height should be equal to or greater than the window height.
- A minimum sash depth of 2 inches is required for inside mount.
- For Outside Mount:
- Measure the desired width where the shade will be mounted. This should typically be 3-6 inches wider than the window frame to ensure complete coverage.
- Measure the desired height. This should typically be 3-6 inches higher than the window frame.

5.2. Installation Steps
Follow these steps for installing your cellular shades. All necessary hardware is included.
- Measure and Mark: Use a pencil to mark the desired locations for the mounting brackets based on your measurements.
- Drill Holes: Drill pilot holes at the marked locations. For inside mount, drill into the top of the window frame. For outside mount, drill into the wall above the window frame.
- Insert Expansion Plugs: If drilling into drywall, insert the provided expansion plugs into the pilot holes.
- Secure Mounting Code: Attach the mounting brackets (also referred to as 'mounting code') using the screws. Ensure they are level and securely fastened.
- Snap Top Rail: Carefully snap the top rail of the cellular shade into the slots of the secured mounting brackets.
- Complete Installation: Ensure the shade is firmly seated in the brackets. Test the shade's operation.

7. Maintenance
To ensure the longevity and appearance of your cellular shades, follow these simple maintenance guidelines:
- Dusting: Regularly dust the shades with a soft cloth, feather duster, or vacuum cleaner with a brush attachment on a low setting.
- Spot Cleaning: For minor spots, gently blot the affected area with a damp cloth and mild detergent. Avoid rubbing vigorously, as this may damage the fabric. Test any cleaning solution on an inconspicuous area first.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can discolor or damage the shade material.
- Keep Dry: Avoid excessive moisture. If the shades get wet, allow them to air dry completely before raising them.
8. Troubleshooting
8.1. Shade Does Not Stay in Position
- Check for Obstructions: Ensure there are no objects or debris interfering with the movement of the shade or the internal spring mechanism.
- Verify Installation: Confirm that the mounting brackets are securely fastened and the shade's top rail is correctly seated. Improper installation can affect the tension of the cordless mechanism.
- Inspect Internal Mechanism: If the shade consistently fails to hold its position, there may be an issue with the internal spring system. This may require professional inspection or replacement.
8.2. Uneven Movement or Sagging
- Check for Damage: Inspect the fabric and internal strings for any visible damage or fraying. A damaged string can cause uneven operation.
- Re-level Shade: Ensure the top rail is perfectly level. An unlevel installation can lead to uneven movement over time.
- Contact Support: If the shade sags or moves unevenly despite checking for damage and proper installation, contact customer service for assistance.
