Section 3 Fill Components
e agent fill station has an inlet hose (agent supply tank hose) designed to connect to the agent supply tank
and an outlet hose (cylinder fill hose) designed to connect to the cylinder fill assembly.
e face of the agent fill station contains three displays (liquid/moisture indicator, inlet pressure gauge,
discharge pressure gauge) and three controls (selector control knob, pump control knob, agent/nitrogen
selection knob). ese displays and controls are described below. Refer to the manual provided with the
agent fill station for more information on any of these features.
3.6.1 Fill Station Displays
e liquid/moisture indicator is used to verify a liquid agent flow through the fill station pump. e inlet
pressure gauge displays the pressure on the agent supply tank side of the fill station pump. e discharge
pressure gauge displays the pressure on the cylinder fill side of the fill station pump.
3.6.2 Selector Control Knob
e selector control knob changes the direction of flow for the fill station. Setting this knob to "systems
cylinder" directs the flow toward the cylinder fill hose. Setting the knob to "recovery cylinder" directs
the flow toward the agent supply tank hose. Setting the selector control knob to "off" places the pump
in a neutral position, stopping the flow to either direction. e selector control knob shall be set to "off"
whenever connecting or disconnecting the agent supply tank hose or cylinder fill hose.
3.6.3 Pump Control Knob
e pump control knob is utilized to adjust the speed of the fill station pump. Turning the knob clockwise
increases the speed and turning the knob counterclockwise decreases the speed. e pump control knob
shall be set to "off" whenever connecting or disconnecting the agent supply tank hose or cylinder fill hose.
3.6.4 Agent/Nitrogen Selection Knob
e agent/nitrogen selection knob changes the fill station pump from agent fill mode to nitrogen fill mode.
e recommended fill procedure as detailed in this manual does not utilize the agent fill station for nitrogen
therefore the agent/nitrogen selection knob should remain set to "liquid Novec 1230" throughout the course
of the fill procedure.
