L. Agent System Leak Test
Leak testing of the machine should be performed using an electronic leak detector to
identify a leakage area and then leak detector fluid to pinpoint the exact location of the
leak.
Leak testing is best performed when the machine is dry of condensation at ambient
temperatures.
Manual ball valves and access valves are installed in several locations of the machine to
allow for isolating sections of the plumbing. The solenoid valves of the machine may also
be used to isolate sections of the plumbing since all of the valves will be closed when not
powered. Use pneumatic diagram, enclosed to best determine the valve closures and
access valve points to use to isolate and depressurize the section of the machine that
contains the leak. AGENT is to be recovered from the appropriate access valve. After the
leakage is repaired, the section of the plumbing exposed to ambient air must be
evacuated to a 1000-micron minimum vacuum level before opening the isolating valves.
