Operating Instructions
Double Sliding Doors
The greenhouse is equipped with two sliding doors for easy access. To open, gently slide the doors along their tracks. Ensure the tracks are clear of debris for smooth operation. Close the doors completely to maintain internal temperature and protect plants from external elements.
Adjustable Roof Vent
The adjustable roof vent allows for ventilation and temperature control. Open the vent to release excess heat and humidity, or to allow beneficial insects for pollination. Close the vent during colder periods or adverse weather conditions. The vent mechanism may be manual or automatic depending on the specific model; refer to your product's specific instructions for operation.
Drainage System
The integrated drainage gutter system collects rainwater from the sloped roof and directs it away from the greenhouse base. Regularly check the gutters for blockages from leaves or debris to ensure efficient water runoff.
Maintenance
Regular maintenance will extend the lifespan of your KEIKI greenhouse and ensure optimal performance.
- Cleaning Panels: Clean polycarbonate panels periodically with mild soap and water using a soft cloth or sponge. Avoid abrasive cleaners or brushes that could scratch the surface.
- Frame Inspection: Annually inspect the aluminum frame for any signs of corrosion, loose bolts, or damage. Tighten any loose fasteners.
- Vent and Door Tracks: Keep door and vent tracks clean and free of dirt or debris to ensure smooth operation. Lubricate if necessary with a silicone-based spray.
- Anchoring: Regularly check the ground anchors for stability, especially after strong winds. Re-secure if any movement is detected.
- Winterization: In areas with heavy snowfall, consider clearing snow from the roof to prevent excessive weight. Ensure all vents and doors are securely closed during cold weather.
