8.2 Maintenance
!
WARNING
Do not use silicone grease on silicone components, as this may cause some parts to
deform. In addition, do not use silicone grease on components in the high pressure
area of the fi rst stage as this would compromise the compatibility with Nitrox mixes.
Maintenance procedures beyond the simple operations described in the preceding
paragraph should not be carried out by the user but only conducted by a SCUBAPRO
Authorized service technician. A SCUBAPRO authorized technician must verify the correct
operation of the regulator every year or every 100 dives, whichever comes fi rst. Conducting
an annual service is also mandatory in order to maintain the limited lifetime warranty.
Servicing is available through SCUBAPRO Authorized dealers identifi ed by the SELECTED
DEALER SCUBAPRO UWATEC sign or by visiting www.scubapro-uwatec.com
9. NITROX
!
WARNING
To prevent severe and potentially lethal injuries DO NOT dive using Nitrox (oxygen
enriched air) mixes unless you have fi rst obtained adequate training and certifi cation
in their use by a recognized certifi cation agency.
!
WARNING
Maximum operating depth (MOD) and exposure times to Nitrox (oxygen enriched
air) mixes are dependent upon the oxygen concentration of the mix in use.
The term Nitrox (oxygen enriched air) defi nes breathable mixes composed of oxygen and
nitrogen and containing oxygen in a percentage higher than 21% (atmospheric air). The
higher oxygen concentration limits the use of these mixes with standard scuba equipment
and requires the use of materials and procedures that differ from those required by the use
of atmospheric air.
USE OF NITROX MIXES OUTSIDE OF THE EUROPEAN UNION
Standard production SCUBAPRO regulators distributed to countries outside of the
European Community use normal INT or DIN connections and are manufactured with
materials, assembly procedures and lubricants that ensure compatibility with gas mixes
containing oxygen up to 40%.
In these countries, users are required to follow the same safety procedures that apply
to dedicated nitrox regulators and to comply with the regulations set by each country
concerning the use on Nitrox mixes for diving.
!
WARNING
If SCUBAPRO regulators have been used with standard compressed air it will be
necessary to perform a new maintenance and cleaning procedure specifi cally
designed for the use of nitrox mixes and carried out by an authorized technician,
before using them again with Nitrox.
