HALOTRON I RECOVERY
using
Amerex P/N 14796 Recovery Cylinder & P/N 14538 Halotron I Recharge Kit
NOTE: In order that a partially discharged or leaking Halotron I extinguisher may
be properly serviced and recharged, it will be necessary to have a Recovery
Cylinder (either empty or with sufficient capacity to void the extinguisher of
remaining Halotron I). The P/N 14796, 35 lb. capacity Recovery Cylinder is ideal
for this purpose.
TRANSFER TO RECOVERY CYLINDER
1. Confirm that the hoses and components are clean and free of debris. Purge all hoses
with argon. Check for leaks and repair if necessary.
2. Ensure that the recovery cylinder is ready for the liquid transfer. It should be either
under a vacuum or have a minimal pressure, about 5 psig (34 kPa).
3. Starting with all valves closed, connect the charging hose female quick connect (toggle
valve end) to the extinguisher fill adapter male quick connect.
4. Connect the charging hose female quick connect to the recovery cylinder fill adapter
male quick connect.
5. Connect the argon gas supply hose female quick connect to the toggle valve male quick
connect.
6. Adjust the toggle valve to direct the flow from the extinguisher to the recovery cylinder.
7. Set the argon regulator to 0 psig (0 kPa) and then open the argon cylinder valve.
8. Set the argon regulator to the extinguisher operating pressure and open the toggle
valve. Depress extinguisher operating lever
– this will pressurize the extinguisher. After
operating pressure is reached, release the operating lever and close the toggle valve.
9. Open the “T” handle valve on the recovery cylinder (rotate towards charging hose).
10. Open extinguisher valve (depress operating lever) to allow the extinguisher contents to
flow into the recovery cylinder.
11. After the flow has stopped, close the extinguisher valve (release operating lever). Close
the recovery cylinder valve.
12. Open the toggle valve to allow the flow of additional argon to repressurize the
extinguisher.
13. Open the extinguisher valve (depress lever) and re-pressurize the extinguisher with
argon to its operating pressure.
14. Close the toggle valve, open the recovery cylinder valve and open the extinguisher valve
(depress lever).
15. After the flow has stopped, close the extinguisher valve (release lever). Close the
recovery cylinder valve.
16. If there is still appreciable liquid in the extinguisher, repeat Steps 12 through 15 as
necessary.
17. Make sure that your area is well ventilated and vent the remaining contents of the
extinguisher and perform the maintenance procedures detailed in P/N 14425 Owner’s
Service Manual prior to recharging the extinguisher.
