5.4.3 End of Line Accessories
All of the following accessories will connect to an End of Line (EOL) Adapter. The EOL Adapter can be installed by following the appropriate procedures
in Section 5.4.1 or Section 5.4.2.
NOTE: End of Line Adapters are not designed to provide a lasting seal without the use of one of the following items:
5.4.3.1 Pressure Gauge (P/N 400195):
The 195 psig Pressure Gauge must be installed with its included O-ring. Thread the pressure gauge into the End of Line Adapter so that the gauge
indicates the tubing pressure.
5.4.3.2 Pressure Switch for End of Line Adapter (P/N 400004):
The Pressure Switch for the EOL Adapter must be installed with its included O-ring and washer. Insert the washer into the EOL Adapter, and then
thread the Pressure Switch in until an audible “click” can be heard. The Pressure Switch is now active.
NOTE: Without installation of the included washer, the Pressure Switch will not be active.
5.4.3.3 End of Line Adapter Plug (P/N 310303):
The EOL Adapter Plug must be installed with its included O-ring. Thread the plug into the End of Line Adapter.
5.4.4 FDT Charging using Nitrogen Charge Kit (P/N 600213)
The FDT Nitrogen charge kit contains:
• Regulator (910550)
• 2x nitrogen cylinders (600214 quantity of two cylinders included in this part number)
• Nitrogen charge adapter to fit into EOL fitting (910600)
• Hard case with foam inserts
The FDT network must have an EOL fitting such as EOL (200168), a pressure switch module with EOL gauge fitting or a manual release (600055)
that can be used for charging the FDT network.
Using the nitrogen charge kit, to pressurize the FDT network follow the steps outlined here:
• Ensure the FDT network is complete (all terminations present – a closed loop)
• Prepare the EOL for installing the charging adapter (910600) by removing the component installed in the EOL position
• Ensure the ball valve is closed on the nitrogen regulator (910550)
• Install a nitrogen cylinder (600214) to the regulator (910550)
• Install the nitrogen charge adapter (910600) into the EOL fitting of the FDT network, ensuring the O-ring is in position, and the adapter fully
engages with the Schrader core inside the EOL fitting
• Connect the regulator outlet (910550) quick disconnect into the installed charge adapter (910600) fitting
• Open the ball valve on the regulator (910550) to start the flow of nitrogen into the FDT network
Charging of the FDT network should only take a few seconds at the most. When the valve is first opened on the regulator, there will be an audible flow
of nitrogen briefly – if you can hear nitrogen discharging from the FDT network at any point, close the regulator ball valve and check the FDT network
for leaks or missing terminations.
Once the FDT network is charged, remove the regulator by pulling the quick disconnect fitting away from the regulator, releasing the charge adapter
fitting.
Remove the nitrogen charge adapter fitting, the Schrader core will engage and keep the FDT network pressurized – there will be an audible pop as
the O-ring seal of the nitrogen charge adapter is removed from the EOL fitting.
Perform a leak check of the FDT network once pressurized.
Install the fitting previously removed from the EOL fitting in order to seal the termination. EOL fittings should not be left with no fittings installed, as the
Schrader core is not designed to be a permanent seal on its own.
Locate the pressure gauge on the FDT network and monitor the pressure for a minimum of 20 minutes, if no pressure drop is noted, proceed with the
commissioning of the system.
