SECTION FOUR A: RDC REPAIR / MAINTENANCE / OVERHAUL
Preliminary
Ensure all high-pressure gas supplies have been
disconnected, and all pressure has been vented.
Open each diver circuit pneumofathometer valve,
to ensure the system is vented, then open each
umbilical supply valve. Ensure the work area and
all tools are clean.
The two and three diver RDC units are
disassembled and reassembled in the same
manner, therefore, this procedure will work for
both with only minor variation. It is strongly
recommended that you take pictures of pneumo
hose routing.

the valve handle retaining nut (12), from each
valve being disassembled, then remove the
lock washer (13) and handle (11).

Removing the entire manifold system from the
foundation plate (1), allows easier access to the
valves. Removing the entire manifold system,
is very quick and easy.
