the head' s sides, protecting the valve from water turbulences
which might lift it, when the inside is depressurized, and flood it.
By the way, on Ellipse balanced second stage a further tee,
can be easily assembled, featuring prolonged exhaust pipes, spe-
cially designed to remove bubbles from the field of vision.
More over, Ellipse Balanced can be used in cold water at tempe-
rature lower than 10C/ 50°F, thanks to its valve' s special design.
The valve inner finning in fact exploits the temperature caused by
the diver' s breathing and allows a remarkable thermal recharge
around the valve nozzle, where the freezing risk is the highest.
This patented system improves dramatically the regulator' s anti-
freezing quality.
WARNING: In case of dives in cold water (temperature
less than 10°C/50° F), Cressi-sub recommend to use a tank
supplied with a valve featuring two separate outlet ports, with
which two complete regulators are to be connected.
WARNING: diving in cold water at temperature lower than
10°C/50 °F requires a special technical training. Cressi-sub
recommend such diving only after attending a special training
course by certified trainers. The use of underwater equip-
ment without a licence or an adequate training may be dan-
gerous for the diver' s health and life. The regulator must not
absolutely get wet and exposed to freezing air before use.
Do not press the discharge button, particularly when the
Venturi effect adjustment lever is on "dive". If possible, keep
the regulator in a warm place before use.
The 2nd stage is connected to one of the first stage' s 3/8" ports
by means of a flexible medium pressure and high capacity hose.
All Cressi-sub second stages are downstream, that is the val-
veautomatically opens in case of calibration loss of first stage or
of a sudden intermediate pressure increase.
This means that any condition of over pressure upstream the
second stage leads to automatic free flow, never causing the reg-
ulator to get stuck. Ellipse Balanced's case is in new techno-poly-
mers showing excellentmechanic qualities, allowing as well to
reduce noises remarkably.
The new cap, only in the adjustable model, featuring an attractive
and aggressive esthetical look, is manufactured with a special in-
sert in titanium, material with unequalled qualities of lightness and
anticorrosion resistance.
It was computer designed, specially studying the water flow insi-
de the front of the case, in order to optimize and further improve
Ellipse Balanced' s already excellent performance.
Ellipse Balanced Cressi-sub complies with 89/686/EEC directive
of 21/12/1989, checked and certified by N. 0474 RINA – Genoa,
with tests in accordance with EN 250:2000 standard, which pro-
vides the requisites of III class Individual Safety Devices: the device
therefore is EC branded and reports the certifying institute indica-
tion (0474), as prescribed by Art. 11A of 89/686/EEC directive.

Disassembly and maintenance
By designing Ellipse Balanced, great attention has been paid as to
the simplicity and speed of disassembly and maintenance, una-
voidable qualities for an always perfectly serviced, set and perfor-
ming regulator.
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-sub.it).
