Installation Guide for UNIVENT in Gardenis Greenhouses and Orangeries

Installing the UNIVENT automated window opener in your Gardenis greenhouse or orangery is a straightforward process that ensures reliable, maintenance-free ventilation.

Follow these steps for proper installation:

1. Prepare the Window

• Ensure the window opens freely and is well-balanced.

• The UNIVENT is best suited for top-hinged or side-hinged vents.

2. Position the Opener

• Mount the main cylinder (with the piston) to the window frame (moving part).

• Attach the bracket arm to the fixed greenhouse structure (wall or roof profile).

• Make sure the mechanism aligns properly and allows smooth opening/closing without resistance.

3. Fixing the Components

• Use the supplied stainless steel fasteners to secure the opener.

• Adjust positioning to suit your preferred ventilation range (typically fully opens around 25 °C).

4. Test the Movement

• Gently open and close the window manually to ensure smooth movement of the piston.

• Leave the vent partially open — as the temperature rises, the UNIVENT will begin to operate automatically.

5. Seasonal Adjustment

• You may fine-tune the temperature activation range by adjusting the tension screw

• Before winter, we recommend removing the cylinder and storing it in a dry, frost-free indoor space. This extends the product’s life and ensures optimal performance in the next season.
