Section 4 Fill Procedure
• Restrain the cylinder assembly securely. It is recommended the cylinder assembly remain placed on the
calibrated scale during the fill procedure.
Do not attempt to ll a cylinder assembly unless the cylinder has been properly restrained. Accidental
discharge of an unsecured cylinder may result in property damage, injury, or death from violent cylinder
movement.
• Replace the anti-recoil safety device with the appropriate Series fill adapter for the cylinder assembly
being filled.
• Connect the fill pressure gauge to the gauge connection port of the cylinder fill assembly.
• Connect the cylinder connection port of the cylinder fill assembly to the male quick-connect fitting of
the fill adapter. Ensure the manual agent fill valve of the cylinder fill assembly is in the closed position
before proceeding.
• Ensure that the pump control knob and selector control knob on the agent fill station are set to "off"
and that the agent/nitrogen selection knob is set to "liquid Novec 1230".
• Connect the agent supply tank hose of the fill station to the liquid fill line of the agent supply tank.
• Connect the cylinder fill hose of the fill station to the pump connection port of the cylinder fill
assembly.
Ensure that the pilot actuation port pipe plug is in place before attempting to ll the cylinder assembly. Failure to
do so may result in agent leaking out of the pilot actuation port during the ll procedure.
• Open the supply tank liquid line valve.
• Set the direction of flow for the fill station towards the discharge outlet. Do this by setting the pump
selector knob to "systems cylinder".
• Slowly open the manual agent fill valve of the cylinder fill assembly.
• Liquid agent flow should be observed in the liquid/moisture indicator window. Once liquid flow is
confirmed, gradually increase the pump speed using the pump control knob.
• Monitor the scale to determine when the cylinder assembly approaches the target fill weight. e target
weight will be approximately the cylinder empty weight plus the intended agent fill weight. Utilize the
pump control knob to increase or decrease the pump speed as necessary.
• Upon reaching the target cylinder weight, close the manual agent fill valve of the cylinder fill assembly
and turn the pump control knob into the off position.
