4. Bend the loop slightly and place the retainer under
the molded lip of the top flange of the filter. This
shallow lip prevents upward movement of the
snapband retainer after proper installation. With the
snapband retainer held against one side of the filter
top interior, slowly allow the retainer to expand into
the recessed area between the lip rim and the four
interior post stops.
5. The snapband retainer should fit snugly between
the lip rim and the vertical post stops. Be sure the
snapband retainer is level and not installed crooked.
A correctly installed snapband retainer will help
prevent any potential leakage at the tubesheet and
keep the filter firmly in place.
