4.2.1 Install rain gauge filter
There’s a stainless steel filter included in the package.
It’s aimed to stop leaves or bird's dropping to avoid the
obstruction of the cone hole. The installation is as simple
as the below figures show:
Hook the filter hook on the edge of the rain collector to
install the filter(as the figure 2 shows on the left).
Take out the filter hook from the edge to uninstall the
filter(as the figure 2 shows on the right).
