Section 4 Fill Procedure
4.3.1 Finalization Procedure
Upon reaching an internal cylinder assembly pressure of 360 psig at 70°F (refer to Table B.1 located in
Appendix B for intended cylinder pressures adjusted for ambient temperatures other than 70°F), the
following steps shall be performed.
• Let the cylinder assembly stand for three hours. Once this three hour period has been completed, check
the cylinder assembly for leak using a soap solution.
• Check the cylinder pressure gauge using the pressure/temperature chart located in the appendix of this
manual.
• Weigh cylinder assembly and record this final weight on the cylinder label and fill log as full weight.
• Properly secure the cylinder assembly for storage or shipping.
NOTE: e final weights and fill information should be recorded on the cylinder label using a permanent-
type fine point marker and protected with a clear overlay label (P/N 17021).
No metal stamps of any type should be used to mark cylinder labels.
4.3.2 Leak Checking
Required Tools:
• Accu-Flow Novec 1230 Calibrated Leak Standard - Leak Rate: 0.48 oz/yr Maximum
• Bacharach H-10 PRO, H25-IR PRO, or Equivalent
All cylinder assemblies must be tested for leakage and shall have a leak rate of no greater than 0.139 percent
of the total amount of the agent fill in a cylinder, per year. Janus Fire Systems specifies the use of Bacharach
Industrial Refrigerant Leak Detector Model H-10 PRO, H25-IR PRO, or equivalent in conjunction with
Novec 1230 calibrated leak standard with a leak rate of 0.48 oz/yr maximum to verify that the refrigerant
leak detector can find or detect cylinder leaks not exceeding the 0.48 oz/yr leak rate established by third
party testing agencies.
NOTE: Submerging H-10 PRO probe in liquid will damage the pump. Exposing the probe to pure agent
will severely reduce the life or destroy the sensor. Exposure to high concentrations of agent may require
adjustment of sensor heat as indicated in H-10 PRO manual
Consult the H-10 PRO Configuration, Operation, and Troubleshooting Manual shipped with the H-10
PRO for instructions on using the leak detector and follow the additional steps below.
1. e units shall be pressurized with Clean Agent and nitrogen as previously indicated.
2. Allow units to stand not less than 10 minutes.
3. Be familiar with and refer to the instruction manual for the H-10 PRO during the leak testing process.
