Section 4 Fill Procedure
4 FILL PROCEDURE
is section contains a step-by-step procedure for weighing, filling, pressurizing, and closing the cylinder
assembly. Refer to Figure 4 for a P&ID diagram that illustrates how each cylinder fill component connects
to the agent fill station, nitrogen supply, and cylinder assembly. Each component should be only installed
when indicated in the sections that follow. Refer to 3M™ Novec™ 1230 Fire Protection Fluid Storage and
Handling document 60-5002-0131-8 for additional information.

4.1 Log and Weigh Empty Cylinder
• Record the serial number of the cylinder assembly in the appropriate section of the fill log. Record the
agent lot number from the supply of Novec 1230 fluid, the fill station number from the agent fill station,
and the date of the fill in the appropriate sections of the fill log and cylinder label.
• Place the empty cylinder assembly on a calibrated scale. Record the weight displayed on the scale in the
appropriate section of the cylinder label and fill log as the empty weight. NOTE: e anti-recoil safety
device shall remain installed in the empty cylinder assembly during weighing. e fill adapter, cylinder
fill assembly, or valve closing adapter shall not be installed during weighing; do not include the weight
of any fill component in determining the empty cylinder weight.
Any trim components installed in the empty cylinder assembly prior to the initial weighing (including anti-recoil
safety device, pressure gauge, and/or low-pressure supervisory switch) shall be installed and included in all
proceeding weight measurements during the course of the ll procedure. Any trim components not installed on
the empty cylinder assembly during the initial weighing shall not be installed or included in any proceeding weight
measurements. Failure to maintain a consistent hardware base for weighing purposes may cause inaccuracy
when using these weights to determine the amount of agent contained in the cylinder assembly.
4.2 Agent Fill Procedure
NOTE: Prior to initiating the agent fill procedure, determine the ambient temperature of the filling location.
Compare this temperature to the values listed in Table B.1 located in Appendix B to determine the final
cylinder pressure required to provide a cylinder pressure of 360 psig at 70°F. An accurate thermometer must
be provided in fill area with no greater than 2°F (1°C) increments.
