INSTALLING THE

ANEMOMETER

Selecting a Location

Select a mounting location for the anemometer that is:

•outdoors, within 10 feet of its solar trans- mitter

•not blocked on the top or sides, so wind can freely reach the anemometer

The best location for the anemometer is usually above roof level on the building where the monitor is located.

Caution: To prevent damage to your weather station by lightning, we recommend you ground the anemometer to the mast, and ground the mast as directed in the installation instructions provided with the mast.

Note: To mount the anemometer, you need a mast (not supplied) about 1–11/4inches (2.54–3.18 cm) in diameter, and the hardware necessary to fasten it to the mounting location. If you previously installed such a mast (for mounting an antenna, for example), you can mount the anemometer and its solar transmitter on that mast.

Mounting the Anemometer/ Solar Transmitter

Important: Be sure you follow the steps listed in “Assembling the Anemometer” on Page 9 before you mount the anemometer.

1.If necessary, mount and ground a mast as directed in the installation instructions provided with the mast.

Warning: Be sure to follow all safety instructions provided with the mast.

2.Using a compass for reference, point the bar on which the anemometer is mounted so the end with the anemome-

ter and wind cup point due south. Then hold the mounting bracket on the end of the bar against the place where you plan to attach it to the mast. Make sure the wind vane is above the wind cup.

3.Place the supplied U-bolts around the mast and through the holes on the ane- mometer’s mounting bracket.

4.Place a washer over both ends of each U-bolt, then place the ring terminal of the anemometer’s grounding wire over the end of one of the bolts.

5.Tighten a nut onto both ends of each bolt (be sure the nuts are snug but not too tight).

6.Check the bar’s position on the mast against the compass to be sure it is still facing due south. Adjust it if necessary, then tighten the nuts on the U-bolts.

7.Place the supplied U-bolts around the mast and through the holes on the ane- mometer’s solar transmitter’s mounting bracket.

8.Place a washer over both ends of each U-bolt.

9.Tighten a nut onto both ends of each bolt (be sure the nuts are snug but not too tight), then tighten the nuts on the U- bolts.

10.Loosen the knurled ring on the anemom- eter’s solar transmitter, adjust the solar transmitter so it faces the sun, then tighten the ring to secure the solar trans- mitter.
