AAF International Front Access Housings - Manual (Page 10)

3.6.6 Preparing the FAH-202-2P-CG, FAH-201-2P-CG, and FAH-
102-2P-HD Housings for Sealing and Locking of the Cassettes:
The FAH-202-2P-CG and FAH-201-2P-CG housings support a single
cassette in each 2 high x 1 wide cavity, while the FAH-102-2P-HD
housing supports a single half cassette in each 1’ high x 1’ wide
cavity. If installed prior to cassette installation, the locking handle
support tabs, which are center-mounted on the vertical panels, would
interfere with the installation of the cassette. For this reason they are
shipped loose with the FAH for installation after the cassette has been
installed. Locate the locking handle support tabs and insert them into
the left hand, right hand, and center panels of the FAH, as shown in
the illustration below. Adjacent housings will share a set of tabs.
Note that the locking handle support tabs are shipped installed
on MD and most HD housings.
3.6.7 Sealing and Locking the Cassettes in Place: The patent
pending AAF SAAF Seal system ensures that the gas phase
chemical filter cassettes are properly sealed into position against
the face gasket to prevent the by-pass of contaminated air around
the filter. The system is designed to be completely effective and to
be simple to operate. Follow the sequence shown in the
accompanying illustrations and as described below:
Step 1: Take one cassette sealing and locking channel.
Step 3: Take one filter seal locking handle.
Step 2: Locate the channel against the left side of the center vertical cassette support panel,
inside the locking handle support tab, with the channel legs facing away from the cassette.
