3.7.2 Handling of the Cassette: The AAF SAAF Cassette is
designed to be sturdy and to support a significant weight of chemical
media. However, it should not be handled roughly. The cassette
should always be lifted with two hands, one beneath each side panel
as shown in the following installation pictures. The cassette should
never be lifted, supported, carried or pulled by a single side panel.
3.7.3 Installation of the Cassettes in the Side Access Housing:
Install the cassettes as shown in the sequence below starting with
the bottom cassette. Slide each half-cassette into the SAH tracks
and push it firmly into the enclosure until the side gasket on the first
half-cassette is firmly compressed against the enclosure wall surface
on the opposite side from the access door on housings accessed
from one side. The plastic edge of the final cassette should be even
with the outer edge of the extruded aluminum track. Repeat this
process until the tracks at each level have been filled.
On housings with access doors on both sides, insert half of the
half-cassettes from one side and the other half from the other side.
Step 1: Prepare to install the half-cassette. Address the air outlet side sealing track at a
slight angle as shown.
Step 2: Engage the upper and lower black hollow core gaskets in the tracks with the
yellow butterfly gaskets on the half-cassette, see Detail – Step 2. Also, begin to align
the upper and lower notches in the half-cassette with the vertical cassette locator bars
which form part of the track.
Step 3: Rotate the cassette slightly 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. See Detail 1 – Step 3 and Detail 2 – Step 3.
