6-3.2 Charging FM-200 Cylinder and
Valve Assembly
Recharge FM-200 cylinder and valve assembly as follows
(see Figure 6-6 and Table 6-6):
WARNING
!
Only qualified, designated personnel should
operate the charging equipment. Exercise
extreme care when working with pressure
equipment to prevent injury to people and
damage to property, resulting from careless
handling or possible equipment failure. Perform
all operations in an assigned area cleared of all
unauthorized personnel. Make sure all equipment
is properly secured. Never attempt to adjust or
disassemble pressurized equipment.
1. Check the cylinder for the last hydrostatic test date prior
to charging. Perform any required DOT hydrostatic tests
(see Paragraph 5-5).
2. Check the cylinder valve assembly for any unaccept-
able physical defects (for example, cracks of any
kind, elongated pits of any length, inclusions of any
size, pitting, bulging, dents, corrosion, fire damage,
mechanical defects, scratches, nicks or gouges if
more than superficial in nature). These defects shall
be cause for rejection.
WARNING
!
Dangerously high pressures may be generated
if FM-200 is introduced into a cylinder
containing nitrogen at a pressure above
10 PSIG (0.7 bar gauge).
3. Weigh the cylinder/valve assembly to verify the quan-
tity of agent in the cylinder. Ensure that no more than
10 PSIG (0.7 bar gauge) of nitrogen is in cylinder be-
fore beginning the fill procedures.
CAUTION
!
FM-200 is a colorless, odorless gas, low in
toxicity, and is an extremely effective fire
suppression agent. FM-200 can be liquefied by
compression, and is normally shipped and
stored in this condition. Being a liquefied and
compressed gas, FM-200 is stored and handled
under saturated conditions (that is, the liquid
and vapor coexist in equilibrium). Reducing the
pressure without reducing the temperature
causes the liquid to flash into vapor with
accompanying refrigeration effects. By
understanding the physical properties of
FM-200 and safe handling techniques, the agent
may be transferred from shipping cylinders to
the desired end-use container safely.
4. Connect the FM-200 supply and return lines to the
FM-200 shipping container valves (Items 19 and 22).
Close all valves in the charging system.
5. Open the FM-200 supply valves (Items 8, 9, 10, 11, 19,
21 and 27). DO NOT open valve (Item 22) at this time.
The pressure gauge (Item 28) should indicate the sup-
ply pressure. Crack the vent valve (Item 30) until
FM-200 liquid is present. Close valve (Item 30).
6. Turn the 3-way valve (Item 9) to the return line posi-
tion. Open valve (Item 24). Crack vent valve (Item 23)
until FM-200 liquid is present. Close valve (Item 23).
Open valve (Item 22). The charging system is now ready
for use.
7. Position the FM-200 cylinder/valve assembly (Item 26)
(with safety cap and pilot actuation port protection cap
in place and properly connected) on a weigh scale (Item
3). Record the weight from the scale. The empty weight
of cylinder assembly must be stamped on the cylinder
valve nameplate.
8. Remove the safety cap and immediately connect the
cylinder assembly into the charging system by assem-
bling the recharge adapter with O-ring packing (Item1)
to the cylinder assembly outlet port.
Note: The main piston in the cylinder valve assembly will
unseat, permitting flow into the assembly when a
10 PSIG (0.7 bar gauge) differential (approximate)
exists at the outlet port. Initial valve assembly seat-
ing occurs with pressure equalization. Final valve
assembly seating occurs with removal of pressure
from valve assembly outlet port and subsequent
momentary application of 450 to 600 PSIG (31 to
41 bar gauge) of nitrogen discussed below.
9. Monitor the scale, record the empty cylinder assembly
weight as A. Determine the charge weight with the equa-
tion C=A+B+N2, where B is weight of FM-200 agent
indicated on valve nameplate.
10. Open valve (Item 29) and start the pump (Item 14).
Monitor the weigh scale (Item 3). When the scale indi-
cates a charge weight C, shut off the pump and close
the FM-200 supply valves (Items 29 and 8).
Note: The 360 PSIG (25 bar gauge) pressure applies to
the filling procedure with nitrogen and FM-200 at
70°F ± 10°F (21°C ± -12°C). When the tempera-
ture is other than 70°F (21°C), refer to Table 6-5
for required total pressure. Do not fill FM-200 cyl-
inders at temperatures below 60°F (16°C) or above
90°F (27°C).
