HALOTRON I EXTINGUISHER SERVICE PROCEDURES
for
A Leaking Extinguisher or Bulk Supply Cylinder
If an extinguisher is leaking but has not lost substantial pressure, the Halotron I can be
recovered following the procedures on Page 7 (Halotron I Recovery). If the extinguisher
has lost all or most of the pressure, which would cause a loss of the gases from the
Halotron I blend, perform the following:
1. Pressurize the extinguisher with argon before attempting a transfer of the contents
into a recovery cylinder.
2. Recover the Halotron I liquid in the extinguisher through the prescribed normal agent
recovery techniques (see page 7) into a Halotron I bulk cylinder (supply or recovery)
which contains “fresh” Halotron I. There will be enough additional gases in the bulk
cylinder to “reconstitute” the recovered Halotron I.
If a bulk cylinder is leaking but has not lost substantial pressure, the Halotron I can be
transferred to a new cylinder by performing the following:
NOTE: If your Halotron I bulk cylinder has lost a substantial amount of
pressure or has lost total pressure, please notify Amerex immediately.
Model 890
– 35 lb. Halotron I Bulk Recharge Cylinder only
1. Attach the P/N 14649 fill adapter to the model 890 operating valve. Connect the
argon supply hose to the adapter, open the “T” handle valve and pressurize the
model 890 to 100 psig (689 kPa). Attach the recharge kit hose assembly to the fill
adapter.
2. Attach the recharge hose assembly to a new empty bulk cylinder which is empty and
under a vacuum.
NOTE: An additional P/N 14649 fill adapter will be required. The Halotron I
recharge kit includes only one.
3. Open the valves on the leaking and new cylinder and transfer the agent into the new
cylinder. When the pressure equalizes and no further liquid is moving from leaking
to new cylinder, close bot cylinder valves. Depress the air (vapor) valve needle on
the “new” cylinder and vent argon gas pressure until the “new” cylinder pressure is
lower than the “leaker”.
4. Detach the recharge hose assembly quick connect from the leaking cylinder and
repressurize with argon to 100 psig (689 kPa).
5. Repeat this process until the maximum amount of liquid Halotron I has been
transferred to the new cylinder. Vent the recharge hose assembly when completed.
Keep in mind that up to a pound heel will always be left in the leaking cylinder.
