systems which are not equipped with rapid relea-
se devices.
• It is unavoidable to know your own equipment and
every related emergency procedure thoroughly.
• We recommend to read the directions for use of
the whole equipment to be used with your dry suit.
• Never dive wearing any equipment which does
not work as it should. Always apply to an autho-
rized centre for any problem.
• Never dive by yourself. Always dive with a part-
ner which is well acquainted with your dry suit
and equipment. Always be sure there are people
ashore or on board which are able to help you in
case of emergency.
• Be aware of your own limits and do not exceed
them.
• Under your dry suit, you should always wear a
thermic under-suit.
MATERIALS AND COMPONENTS
Cressi dry suits are made of neoprene or tri-laminated sheets.
Their function is to insulate the skin from the water, reducing the
dispersion of warmth. The sheets are bound with each other by
means of a special glue and/or stitches which avoid water infil-
trations. A watertight metallic zip fastener is inserted to make
easier to put on the suit.
Watertight zip fastener
The watertight zip fastener allows putting on the suit more easily,
thanks to its wide opening, and guarantees a reliable protection
from the external environment. By means of its teeth, it unites
two rubber edges which prevent the water from getting in. It
may be placed in front crosswise or behind your shoulders hori-
zontally; an overlapping flap improves the comfort and protects
it from impacts and abrasions.
We recommend to ask your partner for help by opening and clo-
sing your zip fastener.
Low pressure pipe
The low pressure pipe leads air to the dry suit' s valve. It must be
connected to one of the LP UNF 3/8" low pressure hole of the
regulator' s first stage or to another low pressure air source. The
maximum pressure must be 15 bar (225 psi.). It is connected to
the valve by means of a quick connection like the b.c.d`s hose.
To connect the pipe to the valve, move back the end, push the
hose onto the nipple and release it. Check the connection by sli-
ghtly pulling the hose. To disconnect the hose, pull back the
sleeve end
and remove it. The hose can be connected or
disconnected even when under pressure and underwater.
Inlet valve
The inlet valve is the air source to inflate the dry suit and it is pla-
ced on its chest.
It must be connected to the low pressure port. You can intro-
duce air inside your dry suit by pressing the inlet button placed
either on the side or in the centre. The valve must not let water
in or discharge air if it is not connected to the hose.
Outlet valve
The outlet valve discharges the air in excess which may have
gathered inside the dry suit, without letting water in. It is placed
on the upper left arm close to the left shoulder. You can dischar-
ge air either manually or automatically:
1. When manually, you have to press its cap with your right hand
keeping your arm raised towards the surface.
2. The air will be discharged automatically, when it reaches a
particular pressure inside the suit. Such pressures can be
limited by screwing and unscrewing the outside cap: turning
it clockwise will open at a greater internal pressure; anti
clockwise will open at a lower internal pressure. Such adjust-
ments determine the quantity of air necessary to keep a
basic balance.
