INTRODUCTION The principles and procedures contained in this manual are intended for the filling and agent recovery associated with the servicing of Amerex Halotron I hand portable fire extinguishers. They are intended for qualified service agencies using the Amerex P/N 14538 Halotron Recharge Kit and any of the Amerex supplied Bulk Recharge Cylinders (Model 890 – 35 lb., Model 891 – 80 lb. or Model 892 – 200 lb.).

B. Personal Protective Equipment To insure proper protection, it is recommended that standard equipment for handling compressed gases and refrigerants be used for filling operations. This would include the use of rubber gloves and eye goggles. All containers (including high pressure gas cylinders) used in filling operations should be secured to stationary objects to prevent uncontrolled movement. It is recommended that persons involved in filling operations refrain from smoking.
PAGE 4
B. Halotron I Filling (Liquid Transfer) Principals Once the extinguisher has been vacuumed, it is ready to be filled with Halotron I (sometimes referred to as Halotron I Presat Base). The filling lines and quick connect used in the filling process should be compatible with Halotron I. Elastomers should be Chloroprene based on EPDM rubber.
PAGE 5
Depending on the temperature when filling the extinguisher, it may be necessary to adjust the final pressure. See temperature vs. pressure charts below. D. Agent Recovery Principles: Halotron I should always be stored and transferred under pressure to ensure that the inert gases in the blend are not released. The Halotron I agent in the extinguisher can be transferred to a recovery cylinder either by a pump or by using pressure differentials.

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.
PAGE 8
NOTE: In the Recovery/Recharge procedure, it will be impossible to completely empty the recovery cylinder contents. A heal in the recovery cylinder of up to 1 pound is normal and should be expected. If recovering a full extinguisher (leaker), the need for an additional supply of Halotron I agent should be anticipated so that the extinguisher may be brought back to its full charged weight.

RECHARGING HALOTRON I EXTINGUISHERS with Amerex Model 890, 35 lb. Halotron I Recharge System & P/N 14538 Halotron I Recharge Kit SET UP INSTRUCTIONS 1. Attach fill adapter P/N 14649 to the recharge cylinder valve. 2. Install “Female Quick connect” end of charging hose assembly with toggle valve to the fill adapter. 3. Verify that there is at least 100 psig of argon pressure in the recharge system cylinder. Add argon gas if required. RECHARGING AN EMPTY HALOTRON I EXTINGUISHER 1.
PAGE 10
SHUT DOWN INSTRUCTIONS After following the above procedure, there may be a small amount of Halotron I left in the charging hose. If it will be more than 8 hours before another extinguisher will be filled, Amerex recommends bleeding this Halotron I off into the atmosphere. The bleed off process will prolong the life of your recharge equipment. Follow this procedure to remove Halotron I captured in the charging hose: 1. Make sure that the Halotron I recharge cylinder is CLOSED. 2.

FILLING (LIQUID TRANSFER) OF HALOTRON I EXTINGUISHERS with Amerex Models 891 (80 lb.) and 892 (200 lb.) Halotron I Recharge Systems and P/N 14538 Halotron I Recharge Kit SET UP INSTRUCTIONS 1. Attach fill adapter (P/N 14648) to the recharge cylinder valve. 2. Confirm that all hoses and components are clean and free of debris. Purge all hoses with argon. Check for leaks and repair if necessary. 3. Install female quick connect end of charging hose assembly with toggle valve to the fill adapter. 4.

FINAL PRESSURIZATION OF HALOTRON I EXTINGUISHERS with Amerex Models 891 (80 lb.) and 892 (200 lb.) Halotron I Recharge System and P/N 14538 Halotron I Recharge Kit FINAL PRESSURIZATION PROCEDURE 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. Start with all valves closed, connect the argon gas supply cylinder female quick connect to the extinguisher fill adapter male quick connect. 3.

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.
PAGE 14
Models 891 and 892 – 80 and 200 lb. Halotron I Bulk Recharge Cylinders 1. Connect the argon supply hose to the vapor valve on the leaking supply cylinder and maintain a constant argon pressure of 100 psig (689 kPa) throughout the transfer. 2. Connect the recharge hose assembly to the liquid supply on the leaking cylinder to the liquid supply on a new cylinder that is under a vacuum. 3. Open the liquid valves on both cylinders to allow the liquid to transfer into the new cylinder. 4.
