3.8 After-filter Installation: It is recommended that a temporary

after-filter be installed in the system to collect an initial plume of dust

that might be blown from the gas-phase chemical filters. If after-filters

have not been provided elsewhere in the system following the gas-phase

filters they should be included in the Side Access Housing. The

installation of the after-filters is exactly the same process as described

for the prefilters in 3.6. See below:

Step 1: Insert the after-filter into the track.

Step 2: The installed after-filter.

Step 4: 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.

Repeat the process of gas-phase cassette installation and sealing

until all SAH modules are filled with sealed cassettes as shown below.

Repeat the process of after-filter installation until all tracks are filled

with after-filters.
