Mounting ISS as a Single Unit (Both Sides Together on a Pole)
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. Take a compass
or local area map to help you determine which direction is north.
It is very important to remember, when mounting both sides together , that
whichever 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.
M OUNTING ON A P OLE
Note: 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 outside diameter of 2-1/2" (64mm).
Start by mounting the rain collector side
1. Place the U-bolt for the anemometer around the pole so that its round end will fit in
the top groove of the rain collector side’s plastic mounting base.
The groove is right above two large holes.
2. While holding the mounting base of the rain collector side against the pole, place the
two ends of the remaining U-bolt around the pole and through the two holes in the
base.
3. Slide the metal backing plate over the bolt ends as they stick out over the rain collec-
tor base. Secure the backing plate with a lock washer and hex nut on each of the bolt
ends as shown above. Do not tighten the nuts yet.
Leave the nuts loose enough to swivel the rain collector side on the pole.
