4. Setup and Assembly
The Palram Canopia Rion Sun Room utilizes a sliding panel assembly system. Careful adherence to the instructions is essential for successful construction.
4.1 Site Preparation
- Choose a flat, level surface for installation. The base must be perfectly square to ensure proper panel and door alignment.
- Clear the area of any debris, vegetation, or uneven ground.
- Ensure adequate clearance around the structure for assembly and future access.
4.2 Assembly Steps
Refer to the detailed graphical instructions provided with your kit for specific step-by-step guidance. The general process involves:
- Base Assembly: Construct the base frame, ensuring it is square and level. This is critical for the entire structure.
- Wall Frame Construction: Assemble the vertical and horizontal aluminum profiles for the side and front walls.
- Panel Insertion: Carefully slide the clear acrylic side wall panels into the designated channels in the frame.
- Roof Frame Assembly: Construct the roof frame, incorporating the roof vent opening.
- Roof Panel Insertion: Slide the twin-wall polycarbonate roof panels into the roof frame channels.
- Door Installation: Attach the hinged door assembly, ensuring it opens and closes smoothly and seals properly. The door can typically be installed to open from either the left or right side.
- Vent Installation: Install the roof vent mechanism.
- Anchoring: Securely anchor the completed structure to the ground and the adjacent wall of your house using appropriate hardware.
Important Note: Some customer feedback indicates that drilling out certain holes may be necessary for proper fit. Proceed with caution and verify alignment before making modifications. Pay close attention to the placement of plastic T-pins; not all holes require them.
5. Operating Instructions
5.1 Door Operation
The Sun Room features a hinged door for access. To open, turn the handle and pull. To close, push the door firmly until it latches. Ensure the door is securely closed to maintain internal temperature and prevent entry of pests.

5.2 Ventilation
The included roof vent allows for air circulation, which is crucial for regulating temperature and humidity, especially when used as a greenhouse. Open the vent manually to allow hot air to escape and fresh air to enter. Consider installing an automatic vent opener (sold separately) for passive temperature control.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Sun Room.
- Cleaning: Clean the polycarbonate and acrylic panels periodically with mild soap and water. Avoid abrasive cleaners or tools that could scratch the surfaces. Rinse thoroughly with clean water.
- Frame Inspection: Annually inspect the aluminum frame for any loose fasteners or signs of corrosion. Tighten as necessary.
- Panel Inspection: Check panels for cracks or damage. Replace damaged panels promptly to maintain insulation and weather resistance.
- Seals: Inspect door and vent seals for wear or damage. Ensure they provide a tight seal to prevent drafts and water ingress.
- Snow Removal: In areas with heavy snowfall, regularly remove accumulated snow from the roof to prevent excessive load. The structure is tested for a snow load of 75 kg/m² (15.4 lb/ft²).

7. Troubleshooting
This section addresses common issues you might encounter with your Sun Room.
- Water Leaks:
- Cause: Improperly sealed panels, damaged gaskets, or insufficient caulking at the base or where it meets the house.
- Solution: Inspect all panel edges and seals. Apply silicone sealant where panels meet the frame and along the base. Ensure the connection to the house wall is properly flashed and sealed.
- Door Not Closing/Latching Properly:
- Cause: Base not perfectly square, frame distortion, or incorrect door installation.
- Solution: Verify the base is square and level. Check door hinges and alignment. Adjust as needed. If the issue persists, re-examine the assembly steps for the door and surrounding frame.
- Panels Flexing/Coming Out in Wind:
- Cause: Insufficient anchoring, loose panel retention clips, or extreme wind conditions exceeding design limits.
- Solution: Ensure the structure is securely anchored to the ground and house. Verify all panel retention clips and T-pins are correctly installed and secure. Consider additional bracing in very windy locations if the issue persists.
- Condensation Inside:
- Cause: High humidity inside and lower temperatures outside, common in greenhouses.
- Solution: Increase ventilation by opening the roof vent more frequently or for longer durations. Ensure proper air circulation.
