4. Tighten the hex nuts using an adjustable wrench or 7/16" wrench.
5. Re-attach the rain collector cone.
6. Set the cone back on the base so its latches slide downward into the latch
openings on the base. Rotate the cone clockwise.
7. While holding the mounting base against the pole, place a U-bolt around the
pole and through the two holes in the base.
8. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.
9. Swivel the anemometer until the arm is pointing north. See the
Vantage
Pro2 ISS Installation Manual

wind vane to point north.
10.Using an adjustable wrench or 7/16" wrench, tighten the hex nuts.
Securing the ISS on the Tripod
Now the ISS is firmly attached to the anemometer extension tube.
1. Insert the swaged end of
the anemometer extension
tube down into the long
extension tube in tripod.
2. Consulting a compass or
local map, turn assembly
until the anemometer arm
points directly north.
3. Place the U-bolt provided
with the tripod around the
tubes where they overlap.
Secure the saddle onto the
U-bolt with the flat wash-
ers, lock washers, and hex
nuts as shown.
4. Tighten the hex nuts quite
firmly, until the U-bolt
begins to dent the tubing
slightly. We recommend
the use of a torque wrench with 25 lb-ft of pressure to fasten the hex nuts.
The support tube should be crimped on the extension tube securely to
prevent any rocking or rotating.
Note:
Do not use over 25 lb-ft torque wrench, it may damage the U-bolts.
