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 ane-
mometer mounting base into the post.
3. Tighten the lag screws using an adjustable wrench or 7/16" wrench.
Note: If your anemometer cannot be mounted aiming true north, you will need to calibrate the wind direc-
tion on your console to display accurate wind directions. See your Vantage Pro2 Console Manual.
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 and/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 and anemomter 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
outside 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 on a smaller pole with the included
U-bolts, the bolt interferes with the rain collector cone.
• Use the built-in bubble level to ensure ISS is level.
