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 II on a level surface. To make sure the surface is
level, use a bubble level or pour water into the T-shaped leveling trough in the collector
base and observe the surface of the water to ensure that the collector is level.
•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 attracts a magnet.
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
1. If you have not already done so, separate the cone from the base.
2. If necessary, disconnect the rain collector cable from the junction box.
3. Locate a suitable mounting surface, using the guidelines above.
4. 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.
5. Make pilot holes using a 3/32" (2 mm) drill bit. You should make the pilot holes about
1/2" (12 mm) deep.
6. Fasten the base to the mounting
surface using the #8 x 3/4" screws
provided
7. Attach the rain collector cable to
the appropriate connector on the
junction box.
8. To be certain the rain collector is
functioning properly after installa-
tion, retest the unit as described
"Testing the Rain Collector II" on
page 2.
9. Once you are sure the unit is func-
tioning properly, place the cone
back onto the base by putting the
latches on the cone into the latch
openings in the base and rotating
the cone clockwise until the latches
"lock" into place.
