Setup and Installation
Your VELUX Solar Blackout Blind is designed for easy installation. Follow these steps to ensure a correct fit and setup.
1. Choosing the Correct Size
You do not need to measure your window. To determine the correct size, locate the reference code on the top part of your open VELUX roof window. This code will correspond to the correct blind size.

2. Compatibility
This blind is compatible with the following VELUX roof window models:
- GGL CK04
- GGU CK04
- GPL CK04
- GPU CK04
3. Installation
The blind features a pre-installed mounting system for quick and easy installation, typically taking only a few minutes. No wiring is required. If mounting brackets are not pre-installed on your window, you may need to purchase the Z0Z 230 kit separately.
Operating Instructions
Your solar blackout blind offers both remote and manual operation for your convenience.
Remote Control Operation
The blind is solar-powered and controlled wirelessly via a pre-paired remote control. Use the remote to open, close, and adjust the blind to any desired position. The integrated rechargeable solar battery provides up to 600 operations even without direct sunlight for recharging.

Blackout Functionality
The high-quality fabric and special aluminum thermal block coating on the back of the blind ensure complete blackout, effectively blocking external light and retaining heat within the room. This makes it ideal for bedrooms or children's rooms.

Maintenance
To keep your VELUX Solar Blackout Blind in optimal condition, follow these simple maintenance guidelines:
- Dusting: Regularly dust the blind fabric and aluminum frame with a soft, dry cloth.
- Cleaning: For more thorough cleaning, wipe the fabric and frame with a damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these may damage the material.
Troubleshooting
Remote Control Pairing Issues
If you experience difficulty pairing the remote control with your blind, or if the blind does not respond:
- Press and hold the RESET button on the blind for 10 seconds. This should initiate the blind's pairing mode.
- Then, press the button with two squares on your remote control.
- If necessary, use the magnetic cursor to fully close the blind, then try operating it again.
The solar battery is designed to provide reliable operation. If the blind is unresponsive, ensure the battery has sufficient charge. It can perform up to 600 operations even without direct sun exposure for recharging.
