How The Air Filter Works; Construction Of The Air Filter Compartment - White Rodgers pmnACM/ACB Owner's Manual

HOW THE AIR FILTER WORKS

Dirty air flows through your return air ducts and enters the
compartment where particles (hair, lint, etc.) are removed
by the filter. See figure 1.
Filtered air re-enters to the supply duct system of your
building.

CONSTRUCTION OF THE AIR FILTER COMPARTMENT

Not only is your air filter compartment easy to install, it is
also easy to maintain. Its basic components, and their
functions, are as follows: (See Figure 2)
Air Filter Compartment- mounts to existing duct work and
houses the filters or optional electronic air cleaner
cells.
NOTE: To upgrade your air filter compartment
with a high efficiency Electronic Air Cleaner, use
the ACR (Air Cleaner Retrofit) Kit for your model.
See page 7 for details.
