The Chshn Electric Smart Curtains System is designed for DIY installation. Please follow these steps carefully. An installation video is available for visual guidance.

4.2. Belt Measurement and Insertion
Measure the correct length of the belt using the black measurement tool provided. Straighten the belt along the track and cut it where indicated. Attach the belt buckles to the ends of the belt and secure them to the carriers. Insert the belts with carriers into the track, sliding them until the carriers reach the end of the track. Ensure both belts are of the same length.
4.3. Carrier Assembly and Runner Insertion
Assemble the two carriers together using the allen wrench. Move the carriers back and forth to ensure smooth operation, especially at the track joints. Insert the appropriate number of runners into the track (approximately 8 runners per 1 meter of track length). Ensure the runners are evenly distributed on each side.
4.4. Gear Box Fastening and Tension Test
Use the loop stop to fasten the gear box. Pull the gear box slightly to test the belt tension, ensuring the belt is not loose. After confirming the tightness, securely fasten the gear box.
4.5. Mounting Options
The system supports both ceiling mounting and wall mounting. For ceiling mounting, ensure adequate space is reserved for the curtain box (more than 10cm for single, more than 20cm for double). If wall brackets are needed, please contact customer service for support.
