Installing the ISS on a Pole
21
Option 2: Installing the Anemometer on a Post or Flat Surface
1. With a 3/16" (5 mm) drill bit, drill two holes approximately 2-1/8" (54 mm) apart. Use
a carpenter’s level to ensure the holes will be level.
2. Insert the 1/4" x 3" lag screws through the flat washers and the holes in the
anemometer mounting base into the post.
3. Tighten the lag screws using an adjustable wrench or 7/16" wrench.
If the anemometer arm is not pointing north, follow the instructions in “Appendix A:
Re-orienting the Wind Vane” on page 28.
Installing the ISS on a Pole
When installing the ISS on a pole, the rain collector and radiation shield section of the
ISS can be mounted as a single unit with the anemometer section, or the two sections can
be mounted separately.
Refer to the following illustration when installing the ISS or anemometer on a pole.
Accessories for Pole Mounting
• Use the Mounting Tripod (#7716) for easy roof-mounting.
• Use the Mounting Pole Kit (#7717) to raise the installation height of the ISS by up
to 37.5" (0.95 m).
General Guidelines for Installing on a Pole
• With the supplied U-bolts, the ISS can be mounted on a pole having an outside
diameter ranging from 1-1/4" to 1-3/4" (32 – 44mm).
• Larger U-bolts (not supplied) can be used to mount to a pole with a maximum out-
side diameter of 2-1/2" (64mm).
• To mount on a smaller pole, obtain a U-bolt that fits the base openings but that has
a shorter threaded section. If mounting the ISS on a smaller pole with the included
U-bolts, the bolt interferes with the rain collector cone.
