4 I. SAFETY INFORMATION THE G2000SS HELMET SHOULD BE USED BY CERTIFIED AND PROPERLY TRAINED DIVERS ONLY. Recommended Umbilical Gas Supply Pressure psi OBP WARNINGS Supply pressure at or below 90 psi OBP may lead to CO2 build-up inside the helmet. Supply pressure above 200 psi OBP may cause the regulator to free flow. The G2000SS helmet is not cleaned or lubricated for oxygen service. Using the helmet with oxygen percentages above 50% by volume may lead to serious injury or death. CAUTION - CONTAMINATED WATER DIVING The helmet should not be used for contaminated water diving (CWD) when only a single exhaust is fitted. A double exhaust adapter kit is available for CWD. When used for CWD with double exhaust fitted, the free flow valve must be open and properly adjusted at all times throughout the dive, as positive pressure inside helmet must be maintained. II. WARRANTY INFORMATION The manufacturer warrants every new helmet to be free from defects in workmanship for a period of ninety (90) days from date of purchase. Parts covered under the Warranty: This warranty covers all metal parts. Parts NOT covered under the Warranty: This warranty does not cover any rubber parts, communications components, headliners, or chrome plating. Due to the electrolytic nature of underwater cutting and welding, chrome plating cannot be warranted when the diver engages in these activities. The Warranty becomes null and void if: The product has been modified without consent of Aqua Lung America, Inc. The product has been misused, damaged or put into situation not intended for products service or if the product has not been correctly maintained according to the G2000SS Diving Helmet Technical Manual. 4

5 III. HELMET SET-UP AND OPERATION SET-UP PROCEDURES Testing the Check Valves : The helmet is equipped with two check valves, one for main air and the other for emergency air. Each check valve should be checked prior to connecting a hose. To check each check valve, the free flow valve must be open and air must be pulled from the check valve to verify that it is closed. The hoses can be attached only after verifying that the check valves are properly functioning. Testing the Emergency Gas Supply (EGS) : After the diver has verified a proper seal of the helmet on his head and the main air is bled from the hose, the diver must turn his emergency (bailout) cylinder valve on and use the bailout regulator to breath inside the helmet. The emergency cylinder valve must then be shut leaving the hose pressurized. The EGS must ALWAYS be turned off at the cylinder valve while diving. CHECKLISTS The following checklists are provided to assist all users and technicians: User: Daily Checklist Pre-Dive Checklist In-Water Checklist for Supervisor Post Dive Checklist Technician: Monthly Inspection & Maintenance Checklist Annual Inspection & Maintenance Checklist UMBILICAL GAS SUPPLY PRESSURES The second stage regulator is designed to provide optimum performance at a driving pressure/over Bottom Pressure (OBP) of 170 psig (11.7 bar). During diving operations the diver s umbilical supply pressure must be maintained between 140 psig and 170 psig (9.65 bar to 11.7 bar) OBP at all times. The OBP must not drop below 90 psig (6.2 bar) at any time: OBP at or below 90 psig (6.2 bar) may lead to CO2 build-up inside the helmet - if this occurs the diver must reduce his workload to avoid exhaustion. The second stage regulator and manifold have a maximum design pressure of approx 200 psig (13.8 bar) over-bottom. 5

6 IV. HELMET MAINTENANCE & PARTS LISTS (1) IMPORTANT NOTES This manual provides factory prescribed procedures for the correct service and repair of the G2000SS diving helmet. It is strongly recommended that all repairs are completed in accordance with this manual. The procedures outlined within this manual are to be performed only by personnel who have received factory authorized training and are certified as a G2000SS service technician. If you do not completely understand all of the procedures outlined in this manual, contact Aqua Lung / Gorski to speak directly with a Technical Advisor before proceeding any further. SCHEDULED SERVICE 1. The G2000SS diving helmet is subject to annual service regardless of usage. 2. The Annual Service Kit (P/N ) contains all parts that are replaced annually. See Appendix J for details of this kit. 3. The Overhaul & Maintenance (Annual) Checklist must be followed for annual service. LUBRICATION Helmets used for air diving or diving with gas containing oxygen percentages less than 50% may be lubricated with food grade silicone such as Dow Corning 111 or equivalent. All O-rings must be lubricated prior to assembly. CAUTION Do NOT lubricate diaphragms or one-way valves. Lubricant attracts dirt and debris and may cause the item to malfunction. COMPONENT INTERCHANGEABILITY The G2000SS is designed specifically so that all new or modified assemblies are interchangeable with, and may be retro-fitted to, all existing helmets. This enhances product support. Certain step-by-step procedures in this manual show older assemblies this demonstrates component interchangeability and makes no difference to helmet performance or functionality. 6

7 IV. HELMET MAINTENANCE & PARTS LISTS (2) GENERAL GUIDELINES 1. In order to correctly perform the procedures outlined in this manual, it is important to follow each step exactly in the order given. Read over the entire manual to become familiar with all procedures before attempting to service or repair the G2000SS helmet. 2. Keep the manual open beside you for reference while performing each procedure. Do not rely on memory. 3. All service and repair should be carried out in a work area specifically set up and equipped for the task. Adequate lighting, cleanliness, and easy access to all required tools are essential for an efficient repair facility. 4. As each unit is disassembled, reusable components should be segregated and not allowed to intermix with non-reusable parts. Delicate parts, including inlet fittings and crowns which contain critical sealing surfaces, must be protected and isolated from other parts to prevent damage during the cleaning procedure. 5. Use only genuine Aqua Lung / Gorski parts provided in the service kits. DO NOT attempt to substitute any part with another manufacturer s, regardless of any similarity in shape or size. Substitution with other manufacturer s parts constitutes an after-market modification of the product, and renders all warranties null and void. 6. Do not attempt to reuse mandatory replacement parts under any circumstances, regardless of the amount of use the product has received since it was manufactured or last serviced.
