EC CERTIFICATION
The MARES regulators described in this manual have been tested and certified by Registered Test Centre No. 0426 - Italcert - Viale Sarca
336, Milano - I, in compliance with EC directive 89/686/EEC of 21 December 1989. The test procedures were conducted according to the
EN 250: 2000 standard, in conformance with the aforesaid directive which sets out the conditions for marketing and essential safety
requirements for Category III Personal Protective Equipment (PPE).
The certification testing results are the following:
Model Warm water Cold Water Marking Position
(Temp. > 10°C) (Temp. < 10°C)
Abyss approved approved CE 0426 On the first stage
Abyss Octopus approved approved CE 0426 On the hose
The CE0426 mark of the Abyss Octopus is an adhesive label affixed to the hose. This label must never be removed. If the label is
accidentally removed, the applicable CE mark for the Abyss Octopus will be the one on the Abyss first stage to which it is connected.
The CE mark certifies compliance with the essential health and safety requirements (DE 89/686/EEC Annex II). The suffix 0426 after the
letters "CE" indicates the Italcert Registered Test Center in charge of monitoring the production under Art. 11B DE 89/686/EEC.
REFERENCES TO EN 250: 2000 - OBJECT - DEFINITIONS - LIMITS
Object: The requirements and tests provided for in EN 250: 2000 are aimed at providing a minimum safety level for the operation of diving
breathing apparatuses at a maximum depth of 50 m / 162 feet.
Scuba - Definition: Self-contained, open-circuit compressed air underwater breathing apparatus is an apparatus which has a portable
supply of compressed air carried by the diver, allowing him to breathe underwater.
Scuba - Minimum equipment (EN 250: 2000):
a) Air tank(s).
b) Regulator.
c) Safety device, e.g. pressure gauge/computer, reserve mechanism 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) User instructions.
Limits (EN 250: 2000)
- SCUBA - Component Units (EN 250: 2000):): The SCUBA unit can be made up of separate pieces of equipment such as a tank,
regulator and submersible pressure gauge. The MARES regulators described in this manual can be used with other SCUBA unit
components certified according to directive EEC/89/686 and EN 250: 2000. The air contained in the tanks must conform to the
requirements for breathable air set out in EN 12021.
- Maximum depth: 50 m / 162 feet.
- Pressure max 232 bar (international YOKE CGA 850 adapter) Fig. 1a.
- Pressure max 200 bar (DIN 477/13 screw) Fig. 1b.
- Pressure max 300 bar (DIN 477/50 screw) Fig. 1c.
- 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.
- The Abyss Octopus second stage can only be used with the Abyss first stage (MR22) or with certified MARES regulators.

WARNING
Diving in cold water (below 10 °C) without special training and equipment may cause serious injury or death. Before diving in
cold water, obtain special training from a certified diving instructor. Since it is not possible to prevent a regulator from freezing
under any and all conditions, MARES regulators too, though equipped with a CWD Kit, might undergo "freeze-up" phenomena.
Should this happen, regulators may not function properly and could cause serious injury or death. Therefore, to minimize risks,
appropriate training is required to prevent or cope with any problems caused by a regulator affected by "freeze- up" phenomena.
The following precautions must be taken when diving in cold water:
1) Do not breath from or exhale through the regulator when out of the water.
2) Press the purge button only when underwater, and then very gently and for very brief periods.
!!
DANGER
MARES regulators and octopus are designed and intended for use only with clean, compressed atmospheric air. Do not
use this equipment with any other gas or enriched air.
Failure to adhere to this warning may result in serious injury or death due to fire and explosion or the serious deterioration
or failure of the equipment.
