Step 2: Address the left and right-hand side support and sealing tracks at a slight angle
as shown. Engage the black hollow core gaskets in the tracks with the yellow butterfly
gaskets on the half-cassette, see detail below. Also, begin to align the left and right-
hand side notches in the half-cassette with the horizontal cassette locator bars which
form part of the track. Step 3: Rotate the cassette slightly upwards so that the vertical locator bars are
inserted into the slots in the half-cassette, while maintaining the compression between
the hollow core and butterfly gaskets. Maintaining a steady and even force on the side
of the cassette, push it into the housing to engage the notches on the outer side of the
half-cassette and continue to insert the half-cassette until it is fully installed.
