Cressi T10 User Manual

The Seal Chamber is composed of a metal cap containing a sili-
con seal. The seal responds to any environmental pressure
change bending towards the inside and transmitting it to the
underlying plate; the latter transmits such information to the main
diaphragm. The main diaphragm protects and seals the device’
s inner mechanism, transmitting pressure changes to the high
pressure valve.
NOTE: before assembling the Seal Chamber S.C. the
balanced diaphragm first stage must be set. In order to get
the regulator to work perfectly, the setting values must be
strictly those reported in the regulator’s performance table.
The setting is independent from the plate transmitting envi-
ronmental pressure changes.
 WARNING: intermediate pressure must be set only at
authorized Cressi-sub centres, while the setting values can
NOT and must NOT be modified by the user, in order not to
affect the regulator’ s performance. Cressi-sub decline any
responsibility for any intervention carried out by unauthorized
personnel.
You can find your authorized Cressi-Sub center by
asking your dealer, or Cressi Sub S.p.A. itself (email:
info@cressi.com).
The MC9 S.C. first stage can therefore be used in cold water (with
water temperature below 10 °C/50 °F), since it complies with Di-
rective 89/686/EEC dated 21/12/1989, checked and certified by
Test Authority No. 0474 RINA located in Genoa, tested in compli-
ance with standard EN 250:2014 that establishes the requirements
for Personal Protective Equipment (PPE) category III. It therefore
bears the CE marking followed by identification of the certification
authority (0474) that checks its manufacture pursuant to module
B+C2 of EU Regulation 2016/425. The standard also dictates the
essential health and safety requirements for Category III PPE and
governs the conditions for bringing it to market.
Its remarkable technical features, together with its high quality
materials, make this first stage a highly reliable regulator, guaran-
teeing best performances for a long time.

1.3 – MC5
MC5 balanced diaphragm 1st stage features an extremely light
and compact structure enclosed in an “esthetical-protective”
shell of a special elastomer, designed to protect the regulator
from collision.
It guarantees high breathing performance in every condition,
thanks to its balanced diaphragm mechanism, allowing the
maximum breathing comfort in every diving phase, starting from
the surface up to the maximum depth. The regulator, in fact,
supplies the same intermediate pressure independently from
the tank pressure, and keeps its performance independently
from the depth.
The balanced diaphragm mechanism, delivering air “on line”,
allows remarkable amounts of air to pass, by a very small pres-
sure decrease between inhalation and expiration phases.
These features are the results of innovating technical solutions
taken by designing MC5 1st stage, making it one of the best
performing small and light regulators on the market.
