  - Tools and Materials Needed
- Note: The rain collector is shipped with the 40 cable coiled and exiting through one of the cable slots. You may want to uncoil the cable and feed it down through the hole in the base behind the tipping spoon.
- Prepare the Rain Collector
  - 1. Remove the cone from the base by rotating the base until the latches on the cone line up with the latch openings in the base, then lifting the cone away from the base.
  - 2. Carefully cut and remove the plastic tie which holds the tipping spoons in place during shipping. TIP: Be careful to not accidentally cut the sensor cable.
  - Test the Rain Collector
    - 1. Open the transmitter shelter on the sensor suite. Remove the foam insert and feed the rain collector cable up through the opening. Plug the cable to the appropriate connector in the sensor interface. (See illustration on page 5.)
    - 2. Press the RAINDAY button on your console to display rainfall.
    - 3. While watching the display on your console to see if it changes, slowly tip the spoon until it drops and comes back up. Each tip indicates 0.01" or 0.2 mm of rain. (It may take up to a minute for the first tip to register at the console.) If the d...
    - 4. When you have finished testing, separate the rain cone from the base and disconnect the rain collector cable from the sensor interface in the transmitter shelter.
- Install the Rain Collector
  - Note: Climbing on your roof may be hazardous. If you are uneasy about installing your unit please have a qualified professional complete the installation. Davis specifically disclaims any liability for injury or loss resulting from the installation o...
    - 1. Remove the rain collector cone if it is installed.
    - 2. 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.
    - 3. Make pilot holes using a 3/32 (2 mm) drill bit. You should make the pilot holes about 1/2 (12 mm) deep.
    - 4. Fasten the base to the mounting surface using the #8 x 3/4 screws provided.
    - 5. If using with a Vantage Pro2 sensor suite or a Sensor Transmitter, open the transmitter shelter on the sensor suite. Remove the foam insert and feed the rain collector cable up through the opening. Plug the cable into the appropriate connector. Re...
    - 6. To be certain the rain collector is functioning properly after installation, retest. SeeSee Test the Rain Collector on page 2
    - 7. To use bird spikes, insert one spike into each socket around the rim of the cone. The sockets are tapered: push firmly or tap lightly with a hammer for a more secure fit. Be careful: bird spikes are sharp.
    - 8. 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. As you reattach the cone, make sure to run the cable through the cabl...
    - 9. Place the debris screen, pointed end up, into the cone. Align the locking grooves with the locks inside the cone and turn to lock the screen in place. If bird nesting is a problem, you can place a spike in the hole on top of the debris screen.
    - Tip: If you choose not to install bird spikes, keep the packet of spikes for possible future use.
      - 10. To prevent fraying or cutting of the cable where it is exposed to weather, it is important that you secure it so it doesnt whip about in the wind.
Use cable clips or weather resistant cable ties to secure the cable. Place clips or ties approximately every 3 to 5 feet (1 to 1.6 m). Do not use metal staples or a staple gun to secure cables. Metal staples, especially when installed with a staple g...
Extending Cable Runs
- Maintaining the Rain Collector
  - 1. Disconnect the rain collector cable from the sensor interface in the transmitter.
  - 2. Separate the cone from the base
  - 3. Use a soft damp cloth to clean pollen, dirt, and other debris from the cone, cone screens, and bucket.
  - 4. Use a pipe cleaner to clear the funnel hole in the cone and the drain screens in the base. When all parts are clean, rinse with clear water.
  - 5. Reattach the cone and replace the debris screen. Reconnect the rain collector cable to the sensor interface.
