original copywriter 1987revised 1998 - printed 1999REGULATORS SERVICE GENERALServicing at the repair shop level mainly involves cleaning,inspection, replacement of necessary parts and adjustment of theregulator.Numerous 0-rings are used throughout the regulator. Cleanlinessis of the utmost importance in obtaining effective 0-ring seals.Tools required for maintenance and repair are shown in the special tools section of this manual.Reusable rubber parts can be cleaned by scrubbing with a softbrush in a mild detergent and water solution. Do not use solventsor acids on rubber or plastic parts. Ideally, metal parts should becleaned in an ultrasonic cleaner with fresh water. However, if anultrasonic cleaner is not available, these parts may be cleanedwith a mild acid (diluted white vinegar is recommended). SERIALIZATIONAll Mares regulators are identified by individuaI serial numbers.The serial number for the complete regulator is located on theregulator second stage case near the mouthpiece. The first stagealso carries the same serial number. WARRANTYThe warranty card is packaged with the regulator and is to begiven to the buyer at the time of sale. The dealer, at the time ofsale, should complete and sign the warranty in its three parts. The«MARES» copy should be mailed to MARES. The «STORE» copyshould be retained by retailer for their records. The «CUSTOMER» copy should be given to the purchaser. The warranty policyas stated in the warranty shipped with the regulator is the finalauthority.The warranty includes also the condition for the regulator to beserviced at least once a year in a MARES Service Center. ROUTINE CAREThe following instructions will help increase the life and properfunctioning of the first stage.1. The first stage should be rinsed with fresh water after everyuse while it is still pressurized on the tank. This allows thesecond stage to be rinsed internally without introducing contaminants into critical sealing areas.2. Thoroughly rinse the first stage and also run water into themouthpiece of the second stage and out of the exhaust tee toremove any foreign matter. lf the regulator is not pressurized,REGULATORS SERVICEIII
IVREGULATORS SERVICEdo not depress the purge button while rinsing. Depressing thepurge button while rinsing may allow particles to contaminatethe valve seat and cause leakage.3. In order to avoid filter and first stage contamination, preventwater from entering the high pressure inlet of the first stage.Place the dust cap over the high pressure filter and secure itwith the yoke screw.4. Allow the regulator to dry completely before storage.5. Prolonged storage in direct sunlight or in oily and dusty areascan be damaging to some of the regulator components.Lubricants are not necessary and should not be used in routine care and maintenance. SERVICE REQUIREMENTSAs stated in the owners manual, regulators should be inspectedand serviced yearly or every 100 hours of use whichever comesfirst. Inspection involves disassembling, cleaning, replacement ofparts as needed, re-assembly and adjustment.Users should not undertake inspections. Only qualified technicians in a MARES Service center should do so.WARNINGPROTECT EYES AND SKIN ADEQUATELY WHEN WORKING WITHANY KIND OF ACID. BEFORE CLEANING METAL PARTS, MAKESURE THAT ALL RUBBER AND PLASTIC PARTS HAVE BEENREMOVED. ACIDS OR OTHER SOLVENTS MAY DAMAGERUBBER AND PLASTIC PARTS.original copywriter 1987revised 1998 - printed 1999

NITROXSTATEMENTNITROX STATEMENT
original copywriter 1987revised 1998 - printed 1999REGULATORSMARES NITROX REGULATORSAll of the regulators in the Mares Nitrox line are specificallydesigned for breathing mixes containing up to 40% oxygen. Theengineering problems arising from the use of such mixtures,particularly with regard to compatibility with plastic polymers andrubber, have been completely resolved through the use of specific materials such as Viton seals and special lubricating greases.DANGERDO NOT USE ANY MARES REGULATOR WITH AN OXYGEN-RICHMIXTURE (NITROX - MAX 40% OXYGEN) WITHOUT FIRST RECEIVING ADEQUATE TRAINING IN ITS USE. FAILURE TO OBSERVETHIS WARNING MAY RESULT IN A SERIOUS ACCIDENT. CONVERSION PROCEDURESWARNING !DO NOT ATTEMPT TO CONVERT MARES REGULATORS - OR ANYOTHER TYPE OF EQUIPMENT - FOR USE WITH OXYGEN-RICH MIXTURES WITHOUT HAVING THE NECESSARY TRAINING AND A THOROUGH UNDERSTANDING OF ALL THE PREPARATION AND ASSEMBLY PROCEDURES FOR HIGH-PRESSURE OXYGEN SYSTEMS.(for US version) Details of these procedures can be obtained fromthe Compressed Gas Association of Arlington, Virginia, USA, orthe American Society of Testing and Materials of Philadelphia,Pennsylvania, USA.WARNING !THE CONVERSION PROCEDURES MUST BE CARRIED OUTEXCLUSIVELY BY QUALIFIED AND AUTHORIZED MARES TECHNICIANS WHO ARE ALREADY FULLY TRAINED IN THE SERVICING OF REGULATORS AND OTHER HIGH PRESSURE SYSTEMSINTENDED FOR USE WITH OXYGEN-RICH MIXTURES.WARNING !AFTER COMPLETING THE CONVERSION AND AFFIXING THELABEL SUPPLIED IN THE KIT ONTO THE SECOND STAGE HOSE,INFORM THE OWNER OR USER THAT THE REGULATOR MUSTNOW ONLY BE USED WITH OXYGEN-RICH MIXTURES. IF, AFTERTHE CONVERSION, THE REGULATOR IS USED WITH ORDINARYCOMPRESSED AIR, IT WILL BE NECESSARY TO REPEAT THEENTIRE CONVERSION PROCEDURE BEFORE USING THE REGULATOR WITH OXYGEN-RICH MIXTURES AGAIN. THIS ISBECAUSE THE REGULATOR MAY BE CONTAMINATED WITHTRACES OF HYDROCARBONS OR OTHER IMPURITIES WHICHCOULD SPARK COMBUSTION.NITROXN 1-1
N 1-2NITROXREGULATORS DISASSEMBLYIn order to avoid contamination of the disassembled components,always work in a clean area that is sufficiently well-ventilated.To convert a regulator for use with oxygen-rich mixtures (MAX40% oxygen) it is necessary to thoroughly clean all the components, removing all traces of silicone and other impurities, andreplacing all O-rings with special ones suitable for this type of use(Viton O-rings). It is therefore necessary to fully disassemble theregulator, following the instructions provided in the separateinstruction manuals for the various regulator models. CLEANING THE COMPONENTSBefore starting the cleaning operations, wear appropriate protective gear for the eyes and hands, and choose a work area that isclean and well ventilated.Before cleaning the components with the specified solutions,remove any excess lubricant using paper towels and a nylontoothbrush.Metal components and hoses:Brass and stainless steel parts can be cleaned by ultrasonic cleaning. If ultrasonic cleaning equipment is not available, these components can also be cleaned using white wine vinegar. Alwayscheck that every component submerged in the solution is perfectly clean, using a magnifying glass if necessary.Next, rinse all components in hot water (distilled water is recommended to avoid mineral residue).Plastic componentsPlastic parts can be cleaned by immersion in a solution of hotwater and a gentle detergent. A nylon brush (such as a toothbrush) can be used to remove any traces of contaminants. Alwayscheck that every component submerged in the solution is perfectly clean, using a magnifying glass if necessary.Rinse all components using warm water (distilled water is recommended to avoid mineral residue). DRYING THE COMPONENTSDry all components using a perfectly clean cloth. Be careful to useoxygen-compatible equipment and low-pressure air, to avoidexposing components to possible contamination due to oil vaporsfrom the tank or compressor. INSPECTING THE COMPONENTSInspect all components, using a magnifying glass if necessary,and make sure that they are all perfectly clean and free of lubri-original copywriter 1987revised 1998 - printed 1999
original copywriter 1987revised 1998 - printed 1999REGULATORScants, oils, silicone grease residue, cuts or shavings. Repeat thecleaning operations and/or replace the damaged components ifnecessary.It is recommended to reassemble the regulator immediately aftercompleting the cleaning and inspection procedures, to minimizeexposure of the components to possible contamination.Make sure that the Viton O-rings used in the conversion are thosespecified on the spare parts list for the regulator model in question.MARES supplies an O-ring kit (cod:185350) which contains allnecessary O-rings for converting all MARES compressed-air regulators currently available on the market, into regulators suitablefor use with breathing mixes containing from 22% to 40% oxygen. The kit also contains a label and a hose protector whichmust be applied on the second stage hose after completing theconversion. LUBRICATIONWARNING !DO NOT USE SILICONE LUBRICANTSBefore reassembling the regulator, it is necessary to lubricate allO-rings and certain other components as described in the servicemanuals. Lubrication prior to installation minimizes the risk ofdamage during reassembly, and helps ensure perfect operationof the regulator.It is essential to use only oxygen-compatible lubricant grease(e.g. “Christo-Lube MCG 111).Lubricate the O-rings using only a small amount of oxygen-compatible grease, because excess grease may attract contaminantparticles, causing the regulator to malfunction. REASSEMBLYBefore starting the reassembly procedure, all tools and equipment used for assembly must be perfectly clean. Clean the toolsusing trichloroethylene or white wine vinegar, then rinse indistilled water and dry using oxygen-compatible low-pressure air.WARNING !MARES RECOMMENDS DEDICATING A SET OF EQUIPMENTEXCLUSIVELY TO THE SERVICING AND CONVERSION OF REGULATORS FOR USE WITH OXYGEN-RICH MIXTURES (MAX 40%OXYGEN).NITROXN 1-3
N 1-4NITROXREGULATORSIn order to avoid contaminating the components with siliconegrease or oil residue on the hands, always work with perfectlyclean hands and wear perfectly clean latex gloves.The reassembly procedures are described in the separate servicemanuals for the various regulator models. ADJUSTMENTSThe adjustment procedures are described in the separate servicemanuals for the various regulator models.WARNING !MARES STRONGLY RECOMMENDS USING ONLY OXYGEN-COMPATIBLE GASES DURING THE ADJUSTMENT AND CALIBRATIONPROCEDURES OF REGULATORS FOR USE WITH OXYGEN-RICHMIXTURES (MAX 40% OXYGEN).original copywriter 1987revised 1998 - printed 1999
