1.6 Assembly – General Comments
As indicated previously, the individual components that will
comprise the filtration system may ship separately and will be
required to be installed on site. The SAAF PORTA-Scrubber is
a self-contained product and, consequently, a minimum
amount of assembly is required. Refer to section 3.0, Installation
Instructions, of this manual for further detailed instructions.
Consult with an experienced installer to obtain an accurate
estimate of the time, personnel, and equipment resources and
tools that will be required to complete the assembly and
installation of the filter system. Site assembly will be limited to
moving and lifting individual components, screwing components
together, and caulking. The PORTA-Scrubber weights and
dimensions can be found on the product drawings. Packages
of the chemical media will typically have a maximum weight of
approximately 50 pounds (23kg). Particulate filters will typically
weigh less than the chemical media filters.
Completion of the following preparations and provision of the
following items will be the responsibility of the installer or others:
• Site preparation
• Connecting hardware for attaching inlet and outlet ducts
• Caulk, as required
• Inlet and outlet ducts, or other sheet metal parts, as required
These items will not be supplied by AAF unless noted specifically
in the AAF quotation and in the accepted customer purchase
order. In general, assembly of the filter system will consist of
the following:
• Preparation of the installation location
• Transportation of all components to the installation location
• Unpacking the PORTA-Scrubber
• Installing the PORTA-Scrubber
• Installing inlet and outlet ducts
• Unpacking particulate filters
• Installing particulate filters
• Unpacking chemical media
• Installing chemical media
• Cleaning the site
• Start-up and commissioning of the filter system
1.7 Related System Equipment
Ventilation systems can include other equipment including but not
limited to:
• Fan(s), if not supplied as part of the PORTA-Scrubber
• Dampers
• Analog instrumentation
• Electronic instrumentation and controls
Neither the interface of these items with the filtration system
supplied by AAF, nor the installation, operation, and maintenance
of these items is covered in this manual. Whether these items are
supplied by AAF or by others, consult the documentation specific
to these products for appropriate instructions.
This list by no means exhausts the possibilities and the system
provided may be different from those shown here. Consult
the AAF drawing that was supplied on the purchase order
in question.
