Maintenance
1. Cover Care
- The high-quality thick PE cover is UV resistant and waterproof. Regularly inspect the cover for any tears or damage.
- Clean the cover periodically with mild soap and water to maintain light transmission and appearance. Avoid harsh chemicals.
2. Stability Checks
- Periodically check the security of the weight bag, ground stakes, ropes, and wall fixings, especially after strong winds or heavy rainfall.
- Ensure the frame connections remain tight.
3. Cleaning
- Wipe down the metal frame with a damp cloth as needed.
- Keep the interior free of debris to prevent pest issues.
4. Repair
In case of minor tears or holes in the PE cover, use the provided repair tape to patch the affected area. Ensure the surface is clean and dry before applying the tape for optimal adhesion.

Troubleshooting
1. Water Accumulation on Roof
The upgraded structure includes additional support bars at the top to increase weight-bearing capability and improve water runoff. If water still accumulates, ensure the cover is taut and properly secured to the frame. Clear any debris that might obstruct runoff.
