XS Scuba Valves Service Manual
Valves that are designated for Maximum 40% Oxygen
Premixed and are being used with elevated oxygen
percentages between 21% and 40% by volume, must
be installed in cylinders which have been cleaned and
tested for oxygen use. All other equipment attached
to the valve, which comes in contact with the oxygen
enriched breathing air (regulator, BC, pressure gauge
etc.) must also be approved by the manufacturer of that
equipment for use with oxygen enriched breathing air
and must be maintained in an oxygen clean condition
as set forth by the manufacturer.
In all cases, if a lubricant is used on the o-rings or upon
insertion of the valve into a cylinder, only use lubricants
approved for oxygen use.
Before attaching the regulator to the valve, open the
valve slightly for an instant to clear the opening of
particles of dust, dirt and to remove any moisture.
ALWAYS OPEN VALVE SLOWLY UNTIL PRESSURE
BUILDS UP THROUGHOUT THE REGULATOR!
All XS Scuba Valves and scuba valve parts are to
be used, installed and maintained per Compressed
Gas Association Pamphlet V-9 “STANDARD FOR
COMPRESSED GAS CYLINDER
VALVES”.
*At the time of this publication, The Compressed Gas
Association (CGA G-7.1) states that Grade E air can
have up to 5 mg/m3 of condensed hydrocarbons.
