PondXpert Easyfilter 4500 - Opening the Filter

Opening the filter
In order to access the filter you will need to remove the metal clamp that holds the
base and lid together.
The lid can then be removed from the base; this will simply pull apart. At first, with
a new unit this may be difficult to remove; do not be alarmed as this is normal.
