Introduction
Congratulations! Continual research and evolution carried out at
our technical centres, together with Cressi-sub’ s usual reliability,
have led to the product you just purchased, which will allow you
to dive comfortably and safely for a long time.
All Cressi-sub regulator are certified to 146 ft (50 m), and some
for use in cold water with temperatures below 10° C, having
passed the stringent operations testing at 4° (+0-2) set forth
under the standard EN 250:2014 (and all previous editions) in
compliance with new EU regulation 2016/425 (ex 89/686/CEE).
This regulation establishes the conditions for bringing to market
and the essential minimum safety requirements for Personal Pro-
tective Equipment (PPE). It will officially take effect April 21, 2018,
abrogating the previous Directive 89/686/EEC, upon the conclu-
sion of a transitional period granted to manufacturers of PPE.
Main Components
Regulators’ main task is reducing the pressure of the compres-
sed air contained in the tank to the same level as the environ-
ment’ s, supplying breathable air when required by the diver.
They are composed of a “first stage”, working as main pressure
reducer and a “second stage” (kept in the diver’ s mouth), which
adjusts the pressure precisely to the same value as the environ-
ment’ s. The regulator is part – together with tank, valves and
sling – of a complete underwater breathing system, known as
“SCUBA” (Self Container Underwater Breathing Apparatus).
This handbook describes all models of Cressi-sub range, all rea-
lized in high quality materials to guarantee pleasant dives and
high performance, together with the easiest ways of use and-
maintenance. The instructions and directions found in this manual
are based on the most up-to-date information about the equip-
ment available before printing.
Cressi Sub reserves the right to make changes at any time.

NOTE: This handbook does not replace a diving training cour-
se! All Cressi-sub devices must be used by divers who have
attended regular courses held by certified trainers.
Using underwater devices without a licence or the necessary
technical training may be dangerous for the diver’ s safety and
life itself.
Besides, in order to guarantee the maximum safety, the devi-
ces must be serviced only by the producer or an authorized-
centre.
You can find your authorized Cressi-Sub center by
asking your dealer, or Cressi Sub S.p.A. itself
(email: info@cressi.com).
WARNING: CRESSI-SUB DECLINE ANY RESPON-
SIBILITY FOR ANY SERVICING CARRIED OUT BY
UNAUTHORIZED PERSONNEL.
WARNING: SCUBA devices complying with EN
250:2014 standard must not be used by more
than a diver at the same time.
WARNING: in case the components of a SCUBA
are set and used by more than a diver at the same
time, their performance in cold water might not
satisfy the requisites prescribed by EN 250:2014
standard.
WARNING: if the components of the SCUBA
equipment are configured and used simultaneously
by multiple divers, the equipment may not be used
at depths of greater than 30 meters, or at water
temperatures below 10 °C (if specified).
