Introduction
This manual provides comprehensive instructions for the assembly, operation, maintenance, and troubleshooting of your SUNMER 3x3M Pop-Up Gazebo. Designed for ease of use and durability, this gazebo features a heavy-duty rust-resistant steel frame, a waterproof 420D Oxford PVC roof, and four removable side walls, including two with windows and two with zipper doorways. It is suitable for various outdoor surfaces and comes with a wheeled carry bag for convenient transportation.
Setup Instructions
The SUNMER Pop-Up Gazebo is designed for tool-free, quick assembly. It is recommended that two or more people assist with the setup process for optimal ease and safety.
1. Unpacking and Initial Frame Setup
Carefully remove all components from the wheeled carry bag. Lay the folded frame on a flat, open surface. Gently pull the outer legs of the frame outwards to begin expanding it.

2. Expanding the Frame and Attaching the Roof
Continue to pull the frame outwards until it is partially expanded. Place the 420D Oxford PVC roof canopy over the top of the partially expanded frame. Ensure the corners of the canopy align with the frame's corner posts. Secure the canopy to the frame using the integrated Velcro straps or clips.

3. Fully Extending the Frame and Adjusting Height
With the roof canopy attached, fully extend the frame by pushing up on the central mechanism until it locks into place. The gazebo frame can be set to three different heights. To adjust the height, locate the push-pin mechanisms on each leg, depress them, and slide the leg to the desired height setting until the pin locks into the corresponding hole.
4. Attaching Side Walls
The gazebo includes four side walls: two with windows and two with zipper doorways. Attach the side walls to the frame using the Velcro fasteners located along the top edge of the walls and the vertical edges of the frame posts. Ensure the zipper doorways are positioned as desired for entry and exit.
5. Securing the Gazebo
For stability, especially in windy conditions, it is crucial to secure the gazebo. Use the provided eight tent pegs to anchor the gazebo legs to soft ground. Attach the four guide ropes to the corners of the roof frame and secure them to the ground using additional pegs. Fill the four sandbags (each capable of holding up to 10kg) with sand or other suitable weight material and attach them to the gazebo legs for added stability.

Operating Instructions
Your SUNMER Pop-Up Gazebo is designed for versatile use in various outdoor settings.
Height Adjustment
The gazebo frame offers three adjustable height settings. To change the height, ensure the gazebo is not under excessive tension. Depress the locking pins on each leg and carefully slide the leg to the desired height. Ensure all four legs are set to the same height and the pins are fully engaged before use.
Side Wall Usage
The four included side walls provide protection from sun, wind, and light rain. The two walls with windows allow for natural light and visibility, while the two walls with zippers provide convenient entry and exit points. Walls can be rolled up and secured with ties if not needed, or completely removed.
Weather Considerations
The roof is made from 420D waterproof Oxford PVC, offering excellent protection against rain. The steel frame is rust-resistant, ensuring durability. While designed for outdoor use, it is advisable to dismantle and store the gazebo during extreme weather conditions such as heavy winds, storms, or snow to prevent damage.

Maintenance
Proper maintenance will extend the lifespan of your SUNMER Gazebo.
- Cleaning: Clean the fabric components (roof and side walls) with mild soap and water. Do not use harsh chemicals or abrasive cleaners. Rinse thoroughly and allow to air dry completely before storage to prevent mildew.
- Frame Care: While the steel frame is rust-resistant, regularly inspect it for any signs of wear or damage. Clean any dirt or debris from the frame. If any rust spots appear, clean them and apply a rust-inhibiting paint.
- Storage: Ensure all components are clean and completely dry before disassembling and packing into the wheeled carry bag. Store the gazebo in a cool, dry place away from direct sunlight when not in use.
- Inspection: Before each use, inspect all parts, including the frame, fabric, pegs, ropes, and sandbags, for any damage or wear. Replace any damaged parts immediately.
Troubleshooting
Here are solutions to common issues you might encounter:
- Difficulty Expanding/Collapsing Frame: Ensure all locking pins are disengaged when collapsing. When expanding, ensure the frame is on a level surface and apply even pressure. If a central pole seems stuck, gently lower the frame slightly to realign components before attempting to push up again.
- Gazebo Instability: Always use the provided tent pegs, guide ropes, and filled sandbags to secure the gazebo, especially in breezy conditions. Ensure the legs are fully extended and locked at the same height.
- Water Pooling on Roof: Ensure the roof canopy is taut and properly secured to the frame. Adjust the height if necessary to create sufficient slope for water runoff.
- Difficulty Fitting into Carry Bag: Ensure all components are folded as compactly as possible. The roof canopy should be folded neatly to maximize space within the bag.
