Preparing the ISS for Installation

3

The Vantage Vue anemometer measures wind speed. The wind cups are mounted on 
the anemometer shaft on the top of the ISS assembly below. 

To mount the wind cups on the anemometer shaft, follow these steps:
1. Gently slide the wind cup assembly down onto the anemometer’s stainless steel 

shaft as far as it will go, as shown below.

2. Use the Allen wrench provided to tighten the set screw near the top of the “hub” 

section of the wind cups, as shown below. Ensure that the set screw is screwed in 
fully and is very tight.

3. Pull gently on the hub to ensure that the anemometer is securely fastened to the 

shaft.

4. Spin the wind cups to make sure they spin freely.

Note: 

If the wind cups don’t spin freely, loosen the set screw, remove them from the shaft, and repeat the wind 
cup installation process.
