USER’S MANUAL FOR MARES DRY SUITS

INTRODUCTION

Congratulations on your purchase of a Mares dry suit. All Mares products are the result of over 70 years of experience and relentless research in new materials and technologies. We hope you will enjoy many great dives with your new equipment.

WARNING

The wrong choice of undergarments and/or gloves and hoods may lead to hypothermia (critical decrease of body core temperature) or hyperthermia (critical increase of body core temperature). This may lead to severe injury or death.

CE CERTIFICATION – EN14225-2:2017

All dry suits described in this manual have undergone an EC type examination, which is the procedure whereby the approved inspection body establishes and certifies that the PPE (Personal Protective Equipment) model in question satisfies the relevant provisions of European Regulation 2016/425.
Said regulation lays down the conditions governing the placing on the market and free movement within the Community and the basic safety requirements which PPE must satisfy in order to ensure the health protection and safety of users. SCUBA dry suits are PPE of category II and are tested according to European Norm EN14225-2: 2017.
All Mares dry suits described in this manual have passed the EC type examination described above and obtained the corresponding CE certification. The examinations are carried out by RINA, notified body 0474, located in Via Corsica 12, 16128 Genova, Italy. CE conformity is denoted by the “CE” marking.
The dry suits described in this manual are manufactured by Mares SpA located in Salita Bonsen 4, 16035 Rapallo (GE), Italy.

APPLICATION

The dry suits described in this manual are intended for use in recreational SCUBA diving activities. There is no inherent depth or water temperature limitation due to the suit, but rather considerations about your own skill and comfort level, breathing gas, inflation gas and passive or active thermal protection will dictate the field of application for the suit. The dry suits described in this manual are not meant for diving in contaminated waters. EN14225-2 specifies that air should be used as inflation gas.

ASSEMBLY

The dry suits described in this manual consist of the dry suit itself, a low pressure inflation hose, and a hood. The low pressure hose has a quick disconnect feature for connecting it to the inflation valve of the dry suit. The other end of the low pressure hose has to be connected to a low pressure port of a first stage regulator. Use a 4mm allen wrench to remove the port plug on the first stage, then screw the threaded end of the dry suit hose into the open port and tighten by hand using a 14mm wrench without using excessive force. Ensure that the hose can easily be connected to the inflation valve when you are fully geared up.

WARNING

The dry suits described in this manual provide little or no thermal protection. Their main purpose is to keep the diver dry. Thermal protection has to be provided in the form of passive or active undergarments and gloves, not provided with the suit. The hood enclosed with the dry suit provides sufficient thermal comfort for most applications, but a thicker or thinner hood may be required for dives in very cold or temperate waters, respectively

WARNING

The wrong choice of undergarments and/or gloves and hoods may lead to hypothermia (critical decrease of body core temperature) or hyperthermia (critical increase of body core temperature). This may lead to severe injury or death.

WARNING

No dry suit can provide total mobility and freedom of movement. This fact combined with the effect of breathing compressed gases while moving through water leads us to recommend that you don’t exert yourself beyond your own comfort level while diving with this suit.

ASSESSMENT OF RISK

A dry suit provides protection from the risk of cold exposure. Cold water, low visibility and strenuous workload are all elements which can increase the risk of an accident during a dive. If you plan to dive in cold water, low visibility or while performing strenuous work, make sure that you have been trained specifically for these conditions by an internationally recognized training agency. Failure to do so may result in serious injury or death.

COLD WATER DIVING

In addition to the guidelines from your cold water diving specialty class, for dives in temperatures below 10°C/50°F we recommend the following as it relates to the use of your dry suit: during the initial descent, descend slowly and inflate your dry suit in short controlled bursts. Inflating continuously over a long time might cause regulator freeze-up and consequent malfunctioning.

CHECKS PRIOR TO USE AND PREPARING FOR THE DIVE

WARNING

• This suit is only to be used by an individual who has had specific training in its use or who is under the supervision of an industry recognized diving
• The use of this suit has the potential to cause buoyancy changes with
• The use of this suit could cause allergic reactions in some
• The termal insulation provided by the suit and undergarment may diminish as depth increases due to the combined effect of compression of materials and addition of expanding compressed gas.
• The underwear used under the dry suit must allow for free passage of air to the exhaust

After this operation disconnect the flexible hose from the inflation valve and rinse your dry suit thoroughly in fresh water after every dive. Avoid contact with solvents and detergents. Ensure that the dust cap is installed on the inflation valve connection prior to doing so. Dry the suit inside first and then outside. Do not leave it to dry in direct sunlight. Store the dry suit on a hanger in a dry place away from direct sunlight. Do not store it near sources of heat and never allow the flexible hose to be crushed. When travelling with your equipment, it is best to use a padded bag such as is commonly used to transport diving equipment. At the end of its useful life, dispose of the suit with your household garbage

MAINTENANCE

Mares recommends a visual inspection every year or 100 dives. If the suit should develop a leak or other malfunction, please take it to an Authorized Mares Dealer for repair.

WARRANTY

The warranty of this dry suit does not cover effects of or damage caused by normal wear or obsolescence of the flexible hose assembly and of any other part of this dry suit. Terms and conditions of the warranty are described on the warranty certificate included with the dry suit.
