SECTION FOUR A: RDC REPAIR / MAINTENANCE / OVERHAUL
Figure 62
ICS Regulator Assembly /
Components Overhaul
Procedure
The ICS should be overhauled using the guidance
provided in this procedure. In normal use, the ICS
regulator should be completely overhauled, at
least every 36 months or less. Units used in
severe conditions such as fuel oil, contaminated
waters, and dusty dirty environments, or units
being used more than 200 dives a year, may
require more frequent overhaul.

Lubrication
XLDS components that require lubrication, should
be lubricated with Christo Lube®. Food grade
silicone, should be used for packing the regulator
piston assembly (38). Christo Lube® may also be
used, however the amount of Christo Lube
required, makes using it in this application costly.
ICS Disassembly
1.
Detach and the remove the ICS cylinder, and
regulator from the back pack, by removing
the mount plate screws (34, 33), washers (31,
32), and mount plate (30).
2.
Slowly open the EGS valve, to ensure the
cylinder is empty.
3.
Unscrew and remove the cylinder from the
ICS regulator, and set aside. Inspect the
cylinder threads, for signs of damage and
corrosion.
4.
Visually inspect the interior of the cylinder,
for signs of corrosion damage. If any corrosion
is/was present, clean the cylinder with warm
soapy water, rinse, dry and re-inspect.
Replace any cylinder, that shows signs of
pitting or thread damage. Ensure the cylinder
is with hydro test date. Any cylinder that is
out of date, or within 3-6 months of being out
of hydro, should be sent out for retesting and
certification.
NOTICE
All parts can be cleaned using an ultrasonic sink if
available. Hand cleaning using a sink or basin is also
acceptable. Followed by a good rinsing drying and
inspection.
