Install the Rain Collector II

Choosing a Location for the Rain Collector
Keep the following in mind when choosing a location for your rain collector:
•You must mount the Rain Collector so that it is level. A built-in bubble level is attached
to the base to simplify this process.
•Be sure there is an unobstructed path for water runoff from the drain screens.
•The Rain Collector II contains a magnet-operated switch which may not operate cor-
rectly if you mount the rain collector on or near any object which is attracted to a mag-
net.
•Exposure to winds can reduce the measured rainfall amounts. Mount the rain collector
where there are no obstructions of rainfall at low angles -- such as trees, houses, fences -
- and as low as possible out of the wind.
To install the rain collector on a sheet metal roof, insulate the unit by making a platform
out of wood. Mount the base of the rain collector at least 1"(4
cm) away from any steel
or iron surface and make sure the reed switch is at least 1" (4
cm) away from any steel or
iron objects (e.g., nails).
•Choose a location which is easily accessible for normal cleaning and is distant from
trees or other sources of heavy pollen or debris.
Installing the Rain Collector II
The following instructions assume the rain collector is being used with a Vantage Pro2 or
Vantage Pro2 Plus ISS. Refer to the user manual that came with our station for more
information.
Tip:
Manuals are available online at www.davisnet.com in the Weather Support section.
1. If you have not already done so, separate the cone from the base.
2. If necessary, disconnect the rain collector cable from the Sensor Interface Module
(SIM).
3. Place the base on the mounting surface and mark the location of the four holes (the
base has eight to choose from) you will use to secure the base.
4. Make pilot holes using a 3/32" (2 mm) drill bit. You should make the pilot holes about
1/2" (12
mm) deep.
5. Fasten the base to the mounting surface
using the #8 x 3/4” screws provided.
