Step 2: Locate the gasket on the edge of the leaving-air
side face of the half-cassette as shown and firmly press
the gasket into position so that it adheres to the face of
the half-cassette. Step 3: Repeat to install the second butterfly gasket
on the other side of the leaving-air side face of the
half-cassette. Step 4: The Type HD half cassette is now ready
for installation into the RU.
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.
Step 1: Bring the HD half-cassette to the RU and prepare to install it. Turn the half-cassette so that the yellow butterfly gasket will be on the bottom and pointing into the enclosure.
3.7.3 Installation of the Cassettes in the RU: Install the cassettes
as shown in the sequence below starting with the bottom cassette(s).
Slide each half-cassette into the RU 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. The plastic edge of the final cassette inserted
should be even with the outer edge of the extruded aluminum track.
Repeat this process until the tracks at each level have been filled.
