Note: Climbing on your roof may be hazardous. If you are uneasy about installing your unit please have a qual- ified professional complete the installation. Davis specifically disclaims any liability for injury or loss resulting from the installation or use of the Rain Collector II. - Page 7 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.
- Page 8 Note: Modify both adjustment screws by the same amount. To check the accuracy of the rain collector, compare the Davis Rain Collector with a tube type rain gauge. Use a rain gauge with an aperture of at least 4 inches. Any smaller and the readings obtained may not be accurate.
- Page 9 Maintaining the Rain Collector II For greatest accuracy, you should thoroughly clean the Rain Collector II at least once or twice a year. 1. Disconnect the rain collector cable from the junction box. 2. Separate the cone from the base.
