If a balancing regulator valve or other component in the system shows
signs of a leak or malfunction, the CAFSAttack system must be removed
from service immediately and repaired and tested before retuning to
service.
DANGER !
ONCE THE AIR CYLINDERS ARE FULLY CHARGED AND THE SYSTEM IS
ENERGIZED, ALL HIGH PRESSURE LINES BETWEEN THE CYLINDER SHUT-
OFF VALVES AND THE PRESSURE BALANCING REGULATOR VALVES,
INCLUDING THE AIR FILTER, ARE EXPOSED TO HIGH PRESSURES (4,500
PSI / 310 BAR).
DO NOT PERFORM ANY SERVICE TO THE HIGH PRESSURE SIDE UNTIL THE
SYSTEM PRESSURE IS RELIEVED. SEE SECTION “6.3 RELIEVING HIGH
PRESSURE,” ON PAGE 59 FOR ADDITTIONAL INFORMATION.
❑ DO NOT operate the system with just air and water. Shut off the air sup-
ply whenever the foam tank is empty.
CAUTION !
COLD WEATHER ENVIRONMENTS CAN CAUSE SOME COMPONENTS TO
FREEZE AND RESTRICT AIR FLOW. COMPONENTS MUST BE THAWED
BEFORE CONTINUING CAFS OPERATION.
❑ NEVER fully empty the air-bottle cylinders. Always maintain a positive
pressure (approximately 50 to 100 PSI / 4 to 7 BAR) within the cylinders.
Positive pressure ensures against moisture and/or dirt contamination in
the tanks, which could also flow back and contaminate the SCBA
recharging cylinders.
Failure to comply could result in serious bodily injury, sickness or
death.
❑ To prevent electrical shock always disconnect the primary power source
before attempting to service any part of the CAFSAttack system.
❑ All electrical systems have the potential to cause sparks during service.
Take the necessary precautions to eliminate explosive or hazardous
environments during any installation and/or service.
❑ To prevent system damage or electrical shock, the main power supply
wire must be the last connection made to the CAFSAttack system.
❑ The CAFSAttack system is designed for use on negative (-) ground,
direct current, electrical systems only.
