Section 3 Fill Components
3.2 Cylinder Fill Assembly
P/N 99517 (See Figure 3.2)
e cylinder ll assembly is formed from a series of interconnected ttings and valves to serve as a connection
point between the agent ll station and the cylinder assembly.
e manual agent ll valve is a 1/4 in (8 mm)
manually actuated ball valve used to open and
close the cylinder ll assembly, allowing agent
to ow from the ll station into the cylinder
assembly.
e cylinder ll assembly has four connection
points. When connected to the cylinder valve
and ll station as recommended, two connection
points are oriented vertically and two connection
points are oriented horizontally as depicted in
Figure 3.2. e vertical connection points are
referred to as the gauge connection port and
the nitrogen pressurization port. e horizontal
connection points are referred to as the pump
connection port and cylinder connection port.
3.2.1 Pump Connection Port
e pump connection port is a 1/4 in (8 mm) male quick-connect tting attached directly to the manual
agent ll valve and serves as the connection point for the agent ll station. e male quick-connect tting
of the pump connection port contains an internal check valve that prevents agent from owing through the
tting unless it is connected to the ll station.
3.2.2 Cylinder Connection Port
e cylinder connection port is located opposite of the pump connection port and is a 1/4 in (8 mm) female
quick-connect tting that serves as the connection point for the 1/4 in (8 mm) male quick-connect tting
on the ll adapter (refer to section 3.1). e female quick-connect tting of the cylinder connection port
contains an internal check valve that prevents agent from owing through the tting unless it is connected
to the ll adapter.
3.2.3 Gauge Connection Port
e gauge connection port is a 1/4 in (8 mm) male quick-connect tting that serves as the connection point
for the ll pressure gauge. It is located on the same side of the cylinder ll assembly as the handle for the
manual agent ll valve. When connected to the cylinder valve, the cylinder ll assembly must be oriented
so that the gauge connection port is perpendicular to the ground and pointing upwards. e male quick-
connect tting of the gauge connection port contains an internal check valve that prevents agent from
owing through the tting unless the ll pressure gauge has been installed to it.
