Cressi T10 User Manual

ENGLISH
The HP poppet valve, which is extremely resilient and easily re-
placed during periodic maintenance, is manufactured in the latest
generation thermoplastic elastomers. This valve boasts the exclu-
sive feature of sliding inside a special lined cylinder, also manufac-
tured in self-lubricating thermoplastic material. The inner surface of
this cylinder, which is completely free of oxidation phenomena,
drastically reduces friction and makes the valve stroke extremely
fluid and precise, guaranteeing optimum respiratory comfort. The
HP poppet valve can also work perfectly guided on a pneumatic
seal compartment, guaranteed to last long thanks to the special
design of the piston sleeve that hinges the valve, without even
making it rotate on its own axis. By doing so, the 1st stage perform-
ance can be kept constant and unchanged over time.
The HP valve closure nozzle, manufactured in stainless steel 316, is
interchangeable to facilitate periodic maintenance of the 1st stage.
Air entry in the first stage is protected by a sintered conical filter in
compact, sintered and nickel-plated phosphor bronze micro-
spheres, to enable better air filtering thanks to the broader filtering
surface guaranteed by the shape which also guarantees the pas-
sage of an elevated air flow, typical of this regulator and withholds
any impurities from tank and valve.
The intermediate pressure regulation system of the T10 balanced
diaphragm 1st stage follows the tradition of all Cressi-sub first
stages, allowing convenient and fast regulation of intermediate
pressure without having to disassemble parts of the regulator.

WARNING: intermediate pressure regulation should only be
carried out by authorised Cressi-sub centres and the calibration
values CANNOT and MUST NOT be changed by the user, to
avoid prejudicing the good working order of the regulator. We
cannot be held in any way liable for any intervention carried out
by staff unauthorised by Cressi-sub.
The Cressi-Sub authorised centres can be indicated
by retailers or, alternatively by Cressi Sub s.p.a.
(email: info@cressi.com).
The balanced diaphragm first stage features a lightweight structure
of compact design, made from seagoing brass, protected on the
surface by means of a PVD (Physical Vapor Deposition) treatment
(version T10SC) or coated with chromed copper (version T10 S.C.
Cromo); the interior components are made of stainless steel,
chromed brass and new generation thermoplastic resins.
It avails of 4 low pressure (LP) 3/8” ports, adequately angled for
optimal distribution of the hoses that avoid interference with the
attached equipment, and 2 high pressure (HP) 7/16” ports with a
micrometric perforation for air release, ensuring maximum safety
also in the event of accidental breakage of the high pressure
hose, avoiding the risk of rapid tank emptying.

WARNING: on the HP ports of the first stage, an underwater
gauge and/or an underwater computer must be connected to
also incorporate the gauge function. Since the tanks are not
equipped with a reserve device, it is absolutely indispensable to
use a gauge that indicates progressive air consumption when
diving and which clearly highlights the reserve pressure has been
reached, which should be considered as unusable air for the
purpose of the dive itself, but only as an emergency air reserve.
Diving without a gauge is dangerous because there is no way of
controlling consumption and you can suddenly find yourself with-
out air during a dive, putting your life in serious danger.
Connection of the first stage to the tank valve can take place
using an international connection, using a new yoke with an ex-
tremely modern design or a threaded coupling DIN 300 bar, both
according to EN ISO 12209 as referenced in the standard EN
250:2014.
As with all regulators in the Cressi-sub range, the T10 first stage
offers the possibility of making certain manufacturing compo-
nents of the regulator compatible, allowing interchanging parts
with other diaphragm first stages in the current range.
