The Crystal Rain Gauge stainless steel mounting bracket should be fixed to a secure support using the four stainless steel screws supplied. A fence post or similar is ideal. Make sure the bracket is vertical so the collection opening is level.
With the bracket mounted, slide in the outer glass cylinder and rotate it so the measurements are visible through the left window.
Assemble the collection funnel and inner cylinder as follows:
1. Check the silicone o-ring is in the groove around the collection funnel and the segmented foam rubber gasket is in place in the funnel spout.
2. Carefully insert the lugs on the inner cylinder in the slots on the funnel, push against the foam gasket and rotate anti-clockwise to secure them. The inner cylinder will now hang from the funnel with the gasket securing it.
3. Carefully lower the funnel and inner cylinder assembly into the outer cylinder and align its graduations so they’re visible from the front of the rain gauge.
