ISS Installation Guidelines

6. Tighten the hex nuts with your fingers only so that the ISS is just secure enough

on the pole for you to release your grip.

7. If you are in the Northern Hemisphere, rotate the ISS on the pole so that the solar

panel is facing south; if you are in the Southern Hemisphere, rotate the ISS so that

the solar panel is facing north. The more precisely the solar panels face due south

or north, the more accurate your wind direction readings will be.

Note: Do not rely on a compass unless it is properly calibrated. In North America there can be up to 15° varia-

tion between true north and a raw compass reading.

8. When the ISS is properly oriented, tighten the hex nuts with a wrench. Do not

exceed 96 inch-pounds (10.8 newton-meters) of torque.

Note: You can refer to the bubble level on the top of the ISS to make sure it is as level as possible.

Finishing the Installation

The wind vane is calibrated at the factory to be accurate when the solar panel is point-

ing south. If your solar panel does not point south, you must calibrate your console so

that it displays accurate wind direction readings. In any case, you can also calibrate

your console to fine-tune your station for greatest accuracy. Refer to your Vantage Vue

Console Manual to calibrate your console.

Note: Calibration must be done if you are in the Southern Hemisphere, or if you are in the Northern Hemisphere

and cannot install your ISS with the solar panel facing south.

Clearing Data Collected During Testing and Installation

Now that the ISS is mounted outside, any data that was collected and stored in the

console during testing and mounting should be cleared.

To clear all the collected data on the console:

1. On the console, press WIND so that selection arrow appears adjacent to the wind

data on the display. Confirm that wind speed is displayed on the compass rose.

2. Press 2ND, then press and hold CLEAR for at least six seconds and until you see

“CLEARING NOW” in the weather center.
