- Maximum depth: 50 m / 162 feet.
- Pressure max 232 bar (international YOKE CGA 850 adapter) Fig. 1a.
- Pressure max 300 bar (DIN 477/50 screw) Fig. 1b.
- Warm water regulators - water temperature over or equal to +10°C (50°F).
- Cold water regulators - water temperature below +10°C (50°F).
Under the EN 250: 2000 standard, water is considered to be cold at a temperature below 10°C. To use MARES regulators in cold water
conditions, always install the CWD (Cold Water Diving) kit. THE CWD KIT SHOULD ONLY BE INSTALLED BY AN AUTHORIZED
MARES SERVICE CENTER.
FOR NORTH AMERICA ONLY
CWD KIT
Because the Proton Ice Extreme is meant to operate in particularly demanding conditions and for professional use in cold water, the V32
first stage is equipped with the CWD kit, which fully isolates all the internal sections of the first stage from contact with the water.
COLD WATER DIVING
According to standard EN 250: 2000, cold water is that at temperatures below 10°C.
Attempting to dive in cold water conditions (below 10°C) without adequate training may result in serious injury. Before
diving in cold water, it is advisable to take a special training course under the supervision of a certified diving instructor.
WARNING
7
Page 3
When diving in cold water conditions, parts of the regulator may be subject to “icing” phenomena. The variables that influence the
possibility of ice forming inside and on the regulator are: temperature of the external environment, water temperature, temperature of the
air in the tanks (and therefore the amount of time that the tanks were exposed to the cold before the dive), fresh water rather than salty,
the level of humidity in the air in the tanks, the amount of air demanded by the regulator during the dive, and the breathing rhythm.
WARNING
Since it is not possible in practice to control all of these variables and therefore to prevent freezing of a second stage in all
situations, the Proton Ice Extreme equipped with the CWD kit could nonetheless demonstrate “icing” phenomena. In this
event, regulators may not function properly. This may result in serious injury. Therefore, to minimize the potential hazards,
it is essential to be adequately trained in the prevention and handling of the problems which may arise from a regulator
subject to “icing” phenomena.
Particularly in these situations, the following precautions should be observed:
1. Take a course to learn cold water diving techniques.
2. Refill the air tanks only at filling stations equipped with an efficient filtering and moisture removal system.
3. When preparing for a cold water dive, keep the tanks and regulator in a place that is sheltered from the cold until just before starting
the dive.
4. Open the tank control valve for one or two seconds to make sure there are no water droplets or small ice crystals. Also check the inlet
opening of the regulator.
5. In the event of repetitive dives, take particular care to ensure that the regulator is perfectly dry before starting the second dive.
6. Avoid breathing from the regulator outside the water.
7. As much as possible, try to prevent water from entering inside the second stage during the dive.
8. Never operate the purge button when not underwater.
9. Use the purge button as little as possible. In any case, never hold it down for more than 2 or 3 consecutive seconds; pressing it for
longer may cause ice to form.
10. Try to breathe normally in order to minimize the cooling effect produced by the higher air velocity during overbreathing.
WARNING
Do not pierce or prick the diaphragm of the CWD and avoid directing powerful jets of water against it (as for example from a
hose). This could puncture the diaphragm or displace it, leading to subsequent oil leaks or infiltration of water. In these cases,
it is necessary to disassemble the CWD kit and replace the diaphragm. This operation must be performed at an authorized
Mares repair shop following the instructions in the maintenance manual.
- The Proton Ice Extreme Octopus second stage may only be used with certified Mares regulator models.
WARNING
For safety reasons, it is not advisable to use an Octopus second stage that is not a certified Mares Octopus. The manufacturer
declines responsibility for damages to persons or property resulting from the use of different Octopus second stages. The Mares
Octopus second stages have been designed and tested for use on first stage low pressure ports OTHER than the preferential
port used for the primary second stage. An Octopus second stage may NOT be substituted for a primary second stage, and
must in no circumstances be connected to the preferential low pressure port intended for the primary second stage.
WARNING
For safety reasons, the submersible pressure gauge / high pressure safety device to be assembled on the regulator must
comply with the standard EN 250:2000. According to this regulation, with an upstream pressure of 100 bar, the maximum
permitted airflow through the connector toward the first stage must not exceed 100 liters/min. If you have a submersible
pressure gauge / high pressure safety device that complies with the EN 250:1993 standard or a different specification,
check whether the instruction manual indicates the value of the maximum airflow.
The use of submersible pressure gauges / safety devices that do not comply with the EN 250:2000 standard, or which do
not have an indication of the maximum permitted airflow through the first stage connector, may result in serious accidents.
GENERAL WORKING PRINCIPLE
Regulators reduce tank pressure, referred to as inlet pressure, to a pressure suitable for breathing. Modern regulators do this in two
stages connected by a hose. The first stage provides pressure to the second stage; this reduced pressure remains constant despite the
sizeable changes undergone by the cylinder inlet pressure during the dive (dropping from 3000/4350 to few hundred psi). The second
stage brings pressure down to ambient pressure and delivers air only when the diver inhales. Each stage of the regulator contains an
internal valve. When the diver inhales, the pressure inside the case is lowered and a pressure differential (imbalance) is created across the
diaphragm (beginning of inhalation). The response of the diaphragm is to bend inward, contact the lever and open the second stage valve.
Air continues to flow into the case until the pressure balance is regained (end of inhalation).
FIRST STAGE
For the second stage to work properly, the first stage must deliver air at a correct and - most importantly - constant intermediate pressure.
This characteristic, provided by all Mares first stages, is essential for obtaining optimal adjustment of the second stage and ensuring top
performance for the entire duration of the dive, regardless of tank pressure. All MARES first stages are available with the following types
of tank valve fittings: international YOKE CGA 850 adapter (max pressure 232 bar), or DIN 477/50 connector (max pressure 300 bar), in
accordance with the standard EN 250:2000.

Page 4
SECOND STAGE
The purpose of the second stage is to deliver air at ambient pressure, only during the inhalation phase. The diagram of a second stage
shown in Fig. 4 illustrates its operation. When the diver inhales, the pressure inside the second stage decreases, creating a pressure
difference (imbalance) between the two sides of the diaphragm. This pulls the flexible diaphragm inward, pressing the demand lever
and unseating the second stage valve. This opening allows air to flow in through the second stage and to the diver, until the diver stops
inhaling. At this point the internal second stage pressure increases, pushing the diaphragm back in the opposite direction, causing the
valve to return to its seat and shutting off the airflow.
V32 First stage (Fig. 2)
The Proton Ice Extreme is equipped with the brand new V32 first stage complete with CWD, and it stands out immediately thanks to its
unique and innovative look, and because it is especially light for a first stage of this level. Its technical characteristics, with a diaphragm
design and DFC system, are those of the famous MR22. The forged brass body with chrome and nickel plated finish is protected by a
shockproof and scratch-resistant coating. The high pressure valve features the SCS spherical seal system, for superior durability. The low
and high pressure ports are positioned to offer the most sensible arrangement of the hoses, ensuring maximum comfort for the user.
DFC system
The exclusive Mares DFC system fitted on the V32 first stage minimizes the intermediate pressure drop which occurs in all regulator first
stages during the inhalation phase (Fig. 3). This phenomenon is all the more marked when higher airflow is demanded of the regulator.
The DFC system substantially reduces breathing effort and inhalation resistance, especially during deep dives and under demanding
conditions. The V32 first stage incorporates the DFC system on the primary LP port. Operation of the other low pressure ports (for
octopus, inflator, etc.) is standard.
Proton Ice Extreme second stage
The most compact metal second stage in the world. Thanks to the integrated VAD system, it offers top-level performance that vastly
exceeds not only the requirements for CE certification, but the stringent U.S. Navy specifications as well. The all-metal technology, coupled
with the fluoropolymer resin coating, makes the Proton ICE Extreme the number one regulator, with unparalleled performance in the cold.
It was tested by the U.S. Navy in extremely cold conditions. Approved for U.S. Navy use in water 29°F / -1.7°C and above.
Indeed, a unique and revolutionary design. The oversized purge button is extremely easy to use, even while wearing thick three-finger
gloves. The “mesh grid” system minimizes the likelihood of free-flow in strong currents. The new design exhaust tee, with its streamlined
shape, affords superior performance while directing air bubbles further away from the face.
The fluoropolymer resin
The fluoropolymer resin on the metal parts of the second stage creates a coating that is resistant to the most aggressive chemical agents.
Naturally non-stick, it prevents ice crystals from attaching to the metal; approved for dietary use, fluoropolymer resin can also be used in
high and low temperatures.
WARNING
Variations in the color of the resin have no effect on performance.
WARNING
Fluoropolymer resin has only one limitation: its low resistance to scratches.
In order to protect the coating on your Proton ICE Extreme, you should follow these instructions:
- During use, protect the second stage from bumps and scrapes.
- Never clean it with abrasive products or sharp objects.
- Always store the regulator so that the second stage is not in contact with abrasive surfaces or spiky metal parts.
WARNING
However, any scratches on the exterior of the second stage will not impair its good performance in the cold.
WARNING
Components with scratch-damaged resin coating will not be replaced under the warranty.
VAD Integrated System (patented)
The Proton Ice Extreme second stage uses the Mares exclusive and patented V.A.D. (Vortex Assisted Design) integrated system. This
system guarantees a low breathing effort at any depth, so that as the air from the hose passes through the second stage valve, it is routed
directly to the mouthpiece via the by-pass tube (Fig. 4). This is a new version of the VAD system, with the bypass tube incorporated into
the technopolymer body of the regulator second stage. This innovative technical development ensures great ease of breathing in an
exceptionally compact and lightweight second stage.
Proton Ice Extreme Octopus
The Octopus version second stage is fitted with a rather lengthy hose (100 cm). Its characteristic yellow color makes it immediately
identifiable under any conditions.

OPERATION AND MAINTENANCE
WARNING
DO NOT attempt to use any kind of adaptor to connect the LP hose to the HP port, as this may lead to serious injury. The
LP components are not designed for use with pressures higher than 20 bar.
Connecting accessories to the first stage
The hoses and accessories should be connected in such a way as to avoid damaging the O-ring. Use a suitable wrench to remove the
plug from the first stage port, and screw the terminal fitting of the hose firmly but gently into the first stage port.
WARNING
The regulator in and of itself is not a complete SCUBA unit, but only one of its components.
Under the EN 250:2000 standard, a complete SCUBA unit must include at least the following Minimum Equipment:
a) Air tank(s).
b) Regulator.
c) Safety device, e.g. pressure gauge/computer, reserve, or alarm.
d) Transport and retaining system, e.g. backpack and/or straps.
e) Facepiece (mouthpiece assembly or full-face mask or diving helmet).
f) Operating instructions.
Your Mares regulator has been designed for use in conjunction with other SCUBA unit components conforming to
the EEC/89/686 directive and certified with the EC mark. The air inside the tanks must conform to the requirements for
breathable air set out in EN12021.
BEFORE ASSEMBLING THE COMPONENTS OF YOUR SCUBA UNIT, CAREFULLY READ ALL THE USER INSTRUCTIONS
AND ANY WARNINGS WHICH THEY CONTAIN.
PRE-DIVE CHECKLIST
- Ensure that all the hoses have been correctly assembled onto the first stage, and check them for cuts, signs of wear or other damage. If
the hoses are loose enough to be unscrewed manually, they must be tightened with a wrench before being pressurised.
- Make sure that the first and second stages do not show signs of damage.
- Position the tank control valve so that the valve opening is directed towards the diver.
10
Page 6
- Remove the dust cap from the regulator yoke and position the A-clamp or DIN fitting so that it is centered on the tank valve opening.
- The first stage should be oriented in such a way that the hose leading to the second stage is routed over the diver’s right shoulder.
- Tighten the yoke nut, or DIN connector, finger tight only, being careful not to damage the O-Ring on the tank valve in the case of a yoke
connector.
- Check the submersible pressure gauge, making sure that the pressure reading is zero.
- Very slowly open the tank valve, allowing air to enter the regulator gradually.
- Do not turn the first stage connected to the tank when the system is pressurized.
WARNING
During this operation, press the purge valve of the second stage. This helps to reduce the impact on the valve (Fig. 5). DO
NOT PERFORM THIS OPERATION AT AMBIENT TEMPERATURES BELOW 10°C (50°F).
- Check the pressure gauge to ensure that it indicates the proper and sufficient tank pressure for your planned dive.
- Check the cylinder and regulator connection for leakage. If leakage exists, it may be caused by incorrectly mounting the regulator on the
valve or by a damaged cylinder valve O-ring.
- To confirm that the regulator delivers air properly, first exhale through the mouthpiece to blow any foreign matter from the second stage,
then inhale. A few breathing cycles should indicate if there are any obvious problems that cannot be discovered by actually breathing
from the regulator while underwater.
DURING THE DIVE
- If you are using a second stage as an Octopus regulator, the dust cap should be used to prevent foreign matter from entering the
second stage through the mouthpiece.
- When the regulator is out of the diver’s mouth, free flowing of air may occur. This inconvenience may be easily eliminated by turning the
regulator downward and lightly shaking it to fill it with water (Fig. 6). Should free flow continue, abort the dive immediately.
POST-DIVE CARE AND PERIODIC MAINTENANCE
Ideally, your regulator should be rinsed with fresh water while pressurized. This allows the second stage to be rinsed internally without
introducing contaminants into critical sealing areas. Rinse the first stage and also run water into the mouthpiece of the second stage and out
of the exhaust tees to remove foreign matter. If the regulator is not pressurized, do not depress the purge button while rinsing. Actuation of
the purge function may allow particles to contaminate the valve seat and cause leakage. In order to avoid filter and first stage contamination,
prevent water from entering the first stage air inlet. Cover the first stage filter with the special dust cup (Fig. 7). Allow the regulator to dry
thoroughly before putting it away. If the regulator is exposed for prolonged periods to direct sunlight, or left in greasy or dusty environments,
some of its components may be damaged. Do not use lubricants. Lubricants should never be used in routine care and maintenance.
WARNING
Proper operation of your regulator also depends on appropriate maintenance. Therefore, your regulator should be
submitted to a Mares authorized service center for inspection at least once a year. In particular, the first stage valve, or the
seat connector (for SCS systems), should be replaced every two years or every 200 hours of diving.
WARRANTY
With the purchase of a Mares regulator, you receive a permanent “Original Owner Identification Card” made of durable plastic. Your card
will have the model and serial number embossed on it. Please print your name and sign in the appropriate space provided. Keep this card,
and present it whenever regulator maintenance is performed by any Mares Authorized Service Center
