SECTION II. EQUIPMENT DESCRIPTION AND DATA
EQUIPMENT CHARACTERISTICS, CAPABILITIES. AND FEATURES.
PORTABLE Used in the field or an indoor area with proper ventilation.
OPERATES OVER WIDE TEMPERATURE RANGE Operating range from + 20°F to + 100°F (-7°C to +38°C).
COMPLETE Requires only Halon supply, nitrogen supply, a recovery cylinder and a continuous compressed air
supply for operation.
1-10.2 Capabilities and Features.
Recovers Halon and nitrogen from fully or partially charged extinguishers and transfers it to a recovery cylinder.
Charges a typical 5 lb. or 7 lb. (2.3 Kg or 3.2 Kg) capacity fire extinguisher in 10 minutes or less when the
ambient air temperature is between +20°F and + 100°F (-7°C and +38°C).
Provides a tilt rack to invert the Halon supply cylinder.
Provides a hoist capable of lifting 600 lb. (272 Kg).
Provides a platform type scale with scale range to 100 lb. (45 Kg) in 4 oz (0.11 Kg) increments for accurate
weighing of fire extinguishers.
Provides a temperature gage with scale range from -20°F to + 120°F (-29°C to +49°C) for accurate nitrogen
pressurization of extinguishers over the operating temperature range.
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.
Major components of the recharger are illustrated in Figure 1-1 and described below. Reference numbers listed below are
keyed to the appropriate assembly illustration in Figure 1-1.
1-11.1 Hoist Winch Assembly (1). Provides a crank operated winch for lifting and placing the Halon cylinder on the tilt
rack assembly (11) and the nitrogen cylinder on the base assembly (10).
1-11.2 Nitrogen Regulator and Hose (2). Controls the discharge pressure from the nitrogen cylinder and directs the flow
of nitrogen to the appropriate valves on the control panel (8).
1-11.3 Scale Assembly (3). Consists of an indicator dial, column, temperature gauge, leveling device and scale platform.
The dial indicates the weight of the fire extinguisher being filled. The dial may be set to zero, using the tare knob on top of
dial, when the empty fire extinguisher is placed on the scale. The leveling device is used to position the scale as level as
possible in the scale frame (5).
1-11.4 Extinguisher Hose Assembly (4). Connects the control panel to the extinguisher to allow transfer of Halon and
nitrogen from and to the extinguisher. Has valve to allow isolation of the extinguisher
1-11.5 Scale Frame Assembly (5). Consists of an aluminum frame which supports the scale assembly (3), and
adjustable (high-low position) fire extinguisher agitator bracket, and provides a frame to support the hoist winch assembly
(1) and nitrogen and recovery cylinders. The agitator bracket consists of a base for
