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.
• The Mounting Pole Kit #7717 can raise the installation height of your 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 diameter pole, obtain a U-bolt that fits the base openings
but that has a shorter threaded section. If you try to mount on a smaller pole with
the included U-bolts, the threaded parts of the bolt will interfere with the rain col-
lector cone.
Guidelines for Installing the ISS on a Pole
• It is very important to remember, when mounting both sides together, that which-
ever side of your ISS is mounted first, the U-bolt from the opposite side ALSO
must be placed around the pole before you tighten anything. (If it is not, there is
no way to slide it in later.)
• In each side’s mounting base, there is a groove to accommodate the other side’s
U-bolt.
• Once you loosely mount the two sides of your ISS together on a pole, you’ll be
able to swivel the unit to the correct direction and then tighten the hex nuts.
• You will also be able to slide it vertically to the desired height.
