Filling (see illustration 2)
The fire extinguisher shall only be refilled by a maintenance service shop with an approval to
“Commission Regulation (EC) No 1702/2003”.
When filling HALON extinguishers the filling station must observe the following instructions:
(1) Determining net weight:
After assembly the empty extinguisher must be placed on a scale to determine the
weight. This net weight must be entered in the check note.
(2) Refilling:
Place the extinguisher on a scale and connect it to the fill station. During the filling process
the release lever of the extinguisher must be held down with a clamp. The weight of this
clamp must be taken into consideration in the weighing process.
The extinguishing agent is filled according to weight. Care must be taken to observe the
permissible fill tolerances.
Portable Fire Extinguishers:
HAL 1 1 Kg HALON 1211 (+0 -0.02 kg)
HAL 1,2 1.2 Kg HALON 1211 (+0 -0.02 kg)
HAL 2,5 2.5 Kg HALON 1211 (+0 -0.02 kg)
After the filling the extinguisher must be pressurized with gaseous nitrogen (99.0 to 99.8
degree of purity, dew point -40°C, (-40°F)). The pressurization for HAL 1, HAL 1,2 and
HAL 2,5 should be according to temperature-pressure curves T565*.
The nominal fill pressure at +15°C is 11 bar (mark in green section of gauge dial). Than
move the closed extinguisher horizontally back and forth to mix HALON and nitrogen
together. In this process the container pressure drops. Depressurize the extinguisher to
the specified pressure. Remove the clamp from container release lever. Secure release
lever. The fill line can than be depressurized and also closed.
