3.4 General Filter System Installation Procedure
3.4.1 Installing the RU: Keeping the RU on its shipping pallet,
move it to its final installation location. Remove the restraints
that secure the RU to its pallet and remove any wrapping or
packaging material.
! WARNING: The housing top will not support the weight of the
unit. Any attempt to support the housing from the top may result in
serious equipment damage and severe personal injury. Do not walk
on the top of the unit or use the top for storage of materials.
3.4.2 Locating, Mounting, and Supporting the RU: Locate the
RU in its final installation location. The support surface under the
base of the frame shall be level, smooth, clean and dry. The
location shall not be subject to standing water or flooding. The
circumference of the housing base shall be fully supported. Adjust
the supports so that the base is level in all directions.
Anchoring the Housing: Depending on the project
requirements, it may not be necessary to anchor the housing.
However, if it should be necessary, a suggestion for anchoring
the standard housing is provided in Figure 4.

In all cases, the foundation and supporting structure shall be
designed for each specific installation by a qualified professional
engineer.
Provision of anchoring hardware or any other supporting component
will be the responsibility of the installer or others. These items will not
be supplied by AAF unless noted specifically in the AAF quotation
and in the accepted customer purchase order.
3.4.3 Connection of Inlet and Outlet Ducts: Inlet and outlet ducts,
when required, shall be connected to the inlet and outlet faces of
the housing as shown in Figure 5.
! WARNING: The housing is not designed to support the weight of
inlet and outlet ducts. All ducts shall be supported independently of the
housing. Any attempt to support the ducts from the housing may result
in serious equipment damage and severe personal injury.
3.4.4 Sealing the Inlet and Outlet Duct Connections: Provide
continuous gaskets, or caulk generously, between the flanges of the
connecting ducts and the housing to prevent air leaks.
Provision of the inlet and outlet ducts, the connecting hardware,
and the gaskets or caulk will be the responsibility of the installer or
others. These items will not be supplied by AAF unless noted
specifically in the AAF quotation and in the accepted customer
purchase order. Any caulk used shall be a long life, flexible, non-
drying caulking material. The caulk supplier shall ensure that the
caulk shall meet the customer specifications for the application in
which it is being used.
CAUTION
Many installations prohibit the use of certain caulking materials such as
Silicone. The use of materials containing VOCs should also be avoided,
as they may have a negative effect on the life of the gas-phase filters.
