Installing the ISS: Installing the ISS on a Flat Surface

Installing the ISS on a Flat Surface

Refer to the following illustration to install the ISS on a post or flat, vertical surface.

Installing the ISS 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.

Use the metal backing plate as your guide when marking the holes.

2. Remove the rain collector cone if it is installed on the ISS mounting base.

3. Insert the 1/4" x 3" lag screws through the metal backing plate and the holes in the

mounting base into the post.

4. Using an adjustable wrench or 7/16" wrench, tighten the lag screws.

5. Re-attach the rain collector cone. Set the cone back on the base so its latches slide

downward into the latch openings on the base. Rotate cone clockwise.

6. Place the debris screen (shown in the illustration on page 2) inside the cone, “feet-

down” over the funnel hole.

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 anemom-

eter mounting base into the post.

3. Using an adjustable wrench or 7/16" wrench, tighten the lag screws.

If the anemometer arm is not pointing north, follow the instructions in “Appendix C:

Re-orienting the Wind Vane” on page 21.
