The Halon transfer pump is not to be operated where the working pressure
exceeds 1000 psi (6895 kPa). The adapter gauge will be damaged.
When the flow of Halon/nitrogen stops, start the pump by rotating the PUMP valve 90 degrees counterclockwise to
the ON position.
When a recovery cylinder pressure reaches 900 psi (6205 kPa) and must be
changed, it should be set aside for a minimum of 24 hours. This will allow
contents to settle and allow input of additional Halon nitrogen mix. This process
may be repeated a maximum of three times or the 900 psi (6205 kPa) pressure is
maintained, whichever occurs first. The recovery cylinder should be marked as to
time and date of last change.
When the INLET PRESSURE gauge on the control panel shows a minus 5 psi (vacuum), or the gauge on the
Halon hose adapter exceeds 900 psi (6205 kPa), close the ball valve on the extinguisher hose. A reading of 900
psi (6205 kPa) requires recovery cylinder change.
Move UNIT OPERAATION valve from RECOVER to OFF.
Place the HALON/NITROGEN valve in the OFF position.
Turn off the pump by rotating the PUMP valve 90 degrees clockwise to the OFF position.
Close the fill valve on the fire extinguisher by slowly rotating the safety control valve clockwise to SET.
Disconnect the extinguisher hose from the fill valve on the fire extinguisher cylinder.
Remove empty fire extinguisher from the agitator bracket.
After all fire extinguishers are processed, place all valves on the hoses, control panel, and recovery cylinder in the
closed or OFF position.
Stop the air compressor.
Remove extinguisher hose adapter from extinguisher hose and place in tool box.
Disconnect Halon hose from recovery cylinder and air compressor hose from air filter.
Stow hoses in approved manner.
If used, remove extinguisher support base from agitator bracket and place in tool box.
