ance and reliability criteria. It's high performance qualities will
deliver years of trouble free service.
All Cressi-sub regulators are certified for use to a depth of 50 m
(150ft) depth as well as for use in cold water, with temperatures
below 10° C, having passed the severe 4° C (+0 -2) test, as
required by UNI EN 250:2000 (European) standards, in compli-
ance with EC Directive 89/686. This Directive sets the provisions
for the marketing and the essential safety requirements for
Personal Protection Equipment (PPE).
Main Components
Regulators reduce the operating pressure of the cylinders to the
actual ambient pressure, thus, supplying the diver with breath-
able air. Regulators consist of a "first stage" for reducing cylinder
pressure and a "second stage" for secondary pressure reduc-
tion to ambient pressure. The combination of the cylinder,
valves, regulator and harness constitutes a SCUBA system,
which stands for Self-Contained Underwater Breathing
Apparatus.
This User Manual illustrates the different regulator models man-
ufactured by Cressi-sub. It provides easy-to-use information on
the performance and maintenance of Cressi-sub regulators. All
Cressi-sub regulators are designed to be compatible with other
Cressi-sub components.
NOTICE: This User Manual is no substitute for proper dive
training! All Cressi-sub Scuba equipment should only be used
by properly trained divers who have attained a diving certifica-
tion from a qualified instructional agency. For your own safety,
proper servicing of your Cressi-sub dive equipment should
always be done at an Authorized Cressi-sub Service Center.
