INSTALLING THE
ANEMOMETER
Selecting a Location
Select a mounting location for the anemome-
ter 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 usu-
ally above roof level on the building where
the monitor is located.
Caution: To prevent damage to your weath-
er station by lightning, we recommend you
ground the anemometer to the mast, and
ground the mast as directed in the installa-
tion instructions provided with the mast.
Note: To mount the anemometer, you need
a mast (not supplied) about 1–1
1
/
4
inches
(2.54–3.18 cm) in diameter, and the hard-
ware 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 list-
ed 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.
