Integrated Compressed Air Foam System

3. Operation
.1 To OPEN Air Supply:
.a Before opening any cylinder valve, verify that the
piping between the cylinder bank and the ICAF
System is properly installed and secured.
.b Slowly open one cylinder valve (C4) and check for
any leak between the cylinder valve, the manifold
and the ICAF System air supply line
(circled item 4) .
If there is no leak, pressure will build up in the
manifold and the piping.
.c Once pressure is stabilized, pressure gauge (C6)
should indicate a minimum pressure of 2200 psi. and
pressure transducer
(C7) should indicate a normal
status at the ARC-1 Release controller.
.d Air pressure gauge (A4) inside the ICAF System
cabinet should indicate a pressure of 100 psi. Refer
to TRIM SCHEMATIC section.
.e Open all of the remaining cylinders.
.2 To CLOSE air supply:
.a Close all cylinders valves (C4).
.b Bleed system manifold and air supply line by opening
system flushing valve (A3). Refer to TRIM
SCHEMATIC section.
4. Recharge cylinders:
After a system discharge or when cylinder pressure is under
the minimum recommended pressure, cylinders must be
refilled with dry air to a storage pressure of 2400 psi @ 70
°
F
(16,536 kPa @ 21
°
C). The following steps must be followed
before sending the cylinders for refilling.
.a Close all cylinder valves (C4).
.b Bleed system manifold and air supply line by opening
system flushing valve (A3). Refer to TRIM
SCHEMATIC section.
.c After all the pressure is removed, pressure gauge
(C6) should indicate a pressure of 0 psi.
.d Remove pressure regulator assembly (C5) and
pressure gauge (C6).
.e Properly plug manifold outlet to prevent any dirt from
contaminating manifold during transport.
NOTICE: Empty cylinders must be recharged by FireFlex
or its trained authorized agent. Contact FireFlex After
Sales Support Department for information about the
nearest authorized agent to your location.
5. Maintenance and inspection:
Regular inspections, tests, and maintenance should be
performed at intervals specified in this document to verify that
the air supply is in good operating condition and that it
functions as intended.
Cylinder inspection:
Storage air pressure shall be checked at least semi-annually.
If the air cylinders bank shows a pressure under 2200 psi. it
shall be refilled or replaced.
Hydrostatic test:
High-pressure cylinders used in ICAF systems shall not be
recharged without a hydrostatic test (and remarking) if more
than 5 years have elapsed from the date of the last test.
Cylinders continuously in service without discharging shall be
permitted to be retained in service for a maximum of 12 years
from the date of the last hydrostatic test. At the end of 12
years, they shall be discharged and retested before being
returned to service.
Cylinders continuously in service without discharging shall be
given a complete external visual inspection every 5 years or
more frequently if required. The visual inspection shall be in
accordance with Section 3 of CGA C-6, Standard for Visual
Inspection of Steel Compressed Gas Cylinders, except that
the cylinders need not be emptied or stamped while under
pressure. Inspections shall be made only by competent
personnel and the results recorded on both of the following:
(1) A record tag permanently attached to each cylinder
(2) A suitable inspection report
A completed copy of the inspection report shall be furnished
to the owner of the system or an authorized representative.
These records shall be retained by the owner for the life of
the system.
Where external visual inspection indicates that the container
has been damaged, additional strength tests shall be
required.
