Franklin Fueling Systems APT Installation Instructions

The APT ducting system allows primary or secondarily contained pipe to be easily retracted and then reinstalled. This
ducting acts as a conduit for the pipe to run through and should not be used as an additional containment layer. APT
ducting can be air tested to check system integrity.
Follow all federal, state and local laws governing the installation of this product and its associated
Warning
systems. When no other regulations apply, follow NFPA codes 30, 30A and 70 from the National
Fire Protection Association. Failure to follow these codes could result in severe injury, death,
serious property damage and/or environmental contamination.
The part described in this document is one element of a system. All components of this system
Caution
should be installed according to the manufacturer's specifications so that the system's integrity is
not compromised. Test the complete system after installation according to all pertinent local, state
and federal laws to ensure its proper operation. Failure to properly verify operation could lead to
environmental contamination.
Procedure
1. Pull the product pipe off of the reel, cut it to the
proper length, square it off and then de-burr the
end of the pipe. If you are using SC (Secondary
Contained) piping, cut back the scuff guard layer
to the sump wall (approximately 9" in dispenser
sumps - tank sump dimensions may vary) and
cut back the SC layer 4½". For further cutback
details, see the process's complete description in
the DWC-XXX Double Wall Cutter (SC) Installation
Instructions or in APT's Installation Guide
Overview. If you're using swage fittings, make
those connections now.
2. Install the ducted-style pipe entry boots in the
sump wall per the ducted entry boot or the ducted
bulkhead boot installation instructions depending
on what type of boot you are using (Figure 1).

3. Pull the ducting and cut it to the proper length, but
don't attach it to any entry boots at this time.
Note: If you're working with two pieces of ducting that need to be
connected, use the DCT-400-F (Figure 2). Use the DCT-
400-F by placing it between the two pieces of ducting and
then tightening the band clamps down onto the ducting.
Do NOT over-tighten the band clamps.
