Maintenance
Depending on the location of your system, the rain gauge may periodically get clogged with dirt,
leaves or other debris. When this happens your rainfall data will appear significantly lower than
other totals in your area or cease to record altogether. Clean the rain gauge as follows:
1. Loosen the 4 screws holding the collector portion onto the base of the rain gauge.
2. Twist the collector counter-clockwise and remove it.
3. Observe the cotter pin holding the plastic screen in place. Straighten the cotter pin
legs to remove it along with the plastic screen.
4. Clear debris from the screen, collector drain, and white dipper assembly.
5. Visually inspect the small circuit board located beneath the white dipping assembly.
If there is evidence of corrosion call RainWise for a replacement switch, which we
will ship with a complete set of installation instructions.
6. Place the screen and cotter pin back in place and bend the cotter pin legs up and
around the inlet as they were before. If they are not bent up and away from the tipper
mechanism they will prevent a complete tip.
7. Replace the collector and tighten the 4 screws.
