3. The KISS GEM as the name implies Gas Extending Mechanism is a simple system that extends the time your gas will last underwater The GEM system will allow the gas in your cylinder to last THREE TIMES AS LONG The GEM utilizes a nitrox mixture allowing you to experience the benefits of diving enriched air nitrox Other benefits that GEM diving offers include the exceptionally small size the light weight fewer parts and complex ity then diving a fully closed rebreather Yet GEM still provides the same benefits that rebreather diving offers warm moist air to breath no noisy rush of bubbles to scare fish away and the benefits of diving enriched air TABLE OF CONTENTS GEM parts list Page 7 Receiving your GEM Page 8 Canister amp scrubber head Page 8 Canister loading Page 10 Wing harness system amp counterlung cover adjustment and placing Page 11 GEM mounting system Page 13 Loop hoses T pieces amp quick disconnect system Page 14 Counterlungs amp counterlung covers Page 15 Lung volume trouble shooting Page 16 Mouthpiece Page 18 Positive amp Negative testing Page 20 T piece 2nd stage use Page 22 Sensor information Page 23 Sensor installation amp display attachment Page 24 GEM wrist display Page 25 GEM wrist display battery warning Page 27 GEM wrist display changing the battery Page 28 GEM wrist display trouble shooting Page 30 Care for Fischer connectors Page 31 Shearwater GEM diving computer Page 32 Diving the KISS
4. With the Shearwater computers you need only set the calibration gas once you will not need to re enter this gas very time you calibrate You only need to change it if you decide to calibrate using a different gas If you do change the calibration PPO2 you will need to recalibrate your com puter prior to diving For calibration at altitude refer to your Shearwater Research users manual Note Changing from semi closed to closed circuit operation will only require recalibration is you are going from semi closed to closed circuit and the calibration PPO2 was below 70 The closed circuit calibration PPO2 must be above 70 Changing the display between PPO2 and FiO2 will not require recalibration NOTE Remember that any changes to the System Setup menu will discard your current calibration If you enter this menu be certain to re calibrate your computer Divers should be aware that when the computer is in SC mode it will require an oxygen sensor to operate The ex ternal sensor can not be disabled This means that in order to use the computer in SC mode it must be linked via the cable to the GEM diving system and sensor Those who dive both the GEM and open circuit can move between SC and OC by changing the setting in the O2 Sefup menu as per 2 above See the following page for calibration instructions 32 33 Shearwater GEM Calibration To calibrate your Shearwater computer the computer should be calibrated to air and then verifie
5. add an additional D ring which can be adjusted to sit at the proper location over the pubic bone Using a crotch strap which is adjustable is preferred 2 The GEM works well with a technical style harness such as the one included If you choose to use a technical harness a crotch strap is important GEM also works with a standard BCD without a crotch strap However the BCD must fit the diver properly If the BCD is loose then a crotch strap might be required We do recommend an adjustable crotch strap to aid in ensuring the lungs and T pieces are situated in the correct spot 3 The GEM mounting system is factory installed onto the webbing cam strap so that the canister sits to the right of the cylinder Divers may choose to slide the mount so that the canister is situated either closer to the divers back or further away This is personal choice 4 When upgrading to the GEM there is a transition though brief You must be aware of your body position In your first few days of training you will find the horizontal position offers the easiest breathing When in a vertical position you may notice slight upward pressure on the mouthpiece By the time you finish your training program it is unlikely that you will notice the difference 5 It is imperative that all the connecting O rings are kept well lubricated hose stubs amp mouthpiece attachments These are all double O ring seals and the tolerances are tight If the O rings are not lubricated
6. ellers screw drivers from your tool kit HOWEVER be very careful that you do not damage the circuit board Replace the battery meter or circuit board as required 28 29 Once you have repaired or replaced the required parts insert the circuit board back into the case Push firmly straight down while ensuring the wire is not pinched on the side Once in place plug the wire back in Use a tiny screw driver to push the wire into the side of the board by where it comes in Also keep wire on bottom side of Souder bump located at the top left side of board This will help keep a small amount of pressure on the connector so it doesn t come undone Now you are ready to install the O ring Check it for nicks and indentations and if you find any discard the O ring and install a new one If you dent the O ring while re attaching the display back discard it and use a new one NOTE This is important as a flawed O ring will allow water to enter the case Apply lubrication generously to the O ring The lubricant will help the O ring remain in place and will also as sist in positioning the display back properly Lubricant should also be applied to the raised edge on the inside of the display back This will ensure that the raised plastic slides past the O ring without catching it Replace the O ring in the case If you are reusing an O ring it will have kept its shape It can go back into the case in the same orientation that
7. Earlier units were shipped with a shorter hose While the shorter hose works for some divers a longer one is required for anyone with either a large chest or who is tall If the LP hose is too short it will pull on the T piece causing it to sit higher then it should This will certainly effect the work of breathing Also ensure that the GEM canister is mounted high enough If it is too low it will pull the T piece and counterlung up and out of position 3 What is your position in the water As mentioned above when in a horizontal position the KISS GEM will have the best work of breathing with vertical being slightly more difficult This will be most noticeable at the start of the training course After several dives most divers hardly notice the difference PATENT PENDING 47 MSL 72 145 Jetsam GEM R 5 48 Warranty The Jetsam Technologies Ltd rebreathers boosters displays and mouthpieces are warranted for the period of 1 year All warranty and service work should be returned to our warehouse e The warranty applies to the original owner only e Mistreatment or neglect of the products will void the warranty e Parts not covered by the warranty are batteries and sensors e Circuit boards and meters sold separately without the case are not covered under the warranty e Warranty cards shipped with rebreathers boosters displays and mouthpieces must be completed and re turned to Jetsam for the warranty to be valid e Completed l

20. the diver The warning on the KISS GEM semi closed rebreather is not a joke Before begin ning your dive you must consider the risks involved The GEM consists of many parts All of these components will eventually fail Careful maintenance assembly and testing will not prevent this from happening At best it will delay the failure The KISS GEM is not automatic in any way It requires constant monitoring a com plete awareness of the potential problems likely to be encountered and full knowledge of how to deal with whatever problems may occur If you do not have adequate training equipment physical conditioning and a proper mindset do not get in the water The diver YOU has the final responsibility for his or her own safety and actions while using this rebreather All components of the KISS GEM must be in good working order and be properly assembled and tested to reduce the risk of failure Regardless of the training and experience of the diver and the reliability of the re breather the risk of serious injury and or death can never be reduced to zero This manual is not a complete text on the maintenance and operation of the KISS GEM The diver must complete a proper training course covering the mainte nance testing and operation of the semi closed rebreather before diving this eguipment The rebreather can malfunction while diving even when properly as sembled and having passed all pre dive tests Only carrying adequate gas and ha
21. the volume in the system has not been depleted WARNING if the mouthpiece is not venting the gas mixture you are breathing could drop to a dangerous level This could cause injury or death especially at shallower depths Prior to diving divers should visually check the left side or inhale mushroom valve and ensure that it is laying prop erly and not damaged Divers should also gently shake the mouthpiece to ensure that they hear feel the right side valve components moving freely back and forth These parts must move freely for the mouthpiece to work properly If they don t move freely the mouthpiece must be serviced Having the mouthpiece serviced by a trained GEM service technician is important If the servicing of the valve is not done properly and lubricant is applied to the wrong parts the valve will stick and not work Lubricant in the right side valve area will cause the inner valve to stick either open or closed If the right side one way valve sticks open you will notice excess bubbles venting from the mouthpiece The unit should not be dove in this manner as the gas is not flowing properly and could cause a problem with carbon dioxide If the valve sticks closed it would be difficult to exhale A sharp exhale would dislodge it but the proper action would be to end the dive and service the mouthpiece WARNING If the mouthpiece right side valve is sticking do not dive the rebreather have the mouthpiece served first Diving t
22. to the right side housing If the inner valve assembly starts to stick either open or closed it is likely that the mouthpiece either needs to be cleaned or that some lubricant has worked its way into the area If a single drop of lubricant is in that area in which the valve moves back and forth it could cause the valve to stick If this happens remove the outer and inner valve assembly Using a perfectly clean cloth their can t be any lubricant on it at all carefully clean the inner part of the mouthpiece All traces of lubricant must be removed Clean the in ner valve assembly and then reattach the outer assembly NOTE if the valve gets stuck it could happen in the open or closed position PATENT PENDING 21 MSL 72 145 Jetsam GEM R 5 22 T PIECE SECOND STAGE USE The second stage is located on the right T piece it is the assembly with the Mikron cover The second stage is de signed to add gas to the breathing loop every time you inhale Whether you are relaxed and not breathing hard or you have a high work load you will always add approximately the same percentage Gas goes into the GEM diving system through the LP hose which is attached to the second stage and runs to the first stage on your cylinder When securing the hose to your 2nd stage tighten the nut finger tight a tool is usually not required Alternatively divers may upgrade and add a quick disconnect to this area so as to simply this process Your first stage IP
23. un derstand that the KISS GEM is NOT a CCR it is a unique diving system and as such the rules are different then those for CCR s In our experience some CCR divers first feel that the lower loop hoses are very long and don t understand why this is so Also that the counterlungs should sit higher Shorter hoses improperly placed lungs and T Pieces will make for a difficult dive It is important that experienced CCR divers keep an open mind and learn to dive the GEM the way it has been designed e The T piece must sit either on the divers centre chest or slightly above centre chest the nipple line This posi tioning ensures that the GEM will function properly If the lungs and T pieces are too high the work of breathing will be higher and the GEM s gas addition systems won t work properly Previously we had stated that the lungs should be positioned by lining up the top of the lung cover with the clavicle bone We have found this isn t true for all body types As such it is important that current recommendations are followed e As the T pieces sit on the divers chest the lower loop hoses need to be long enough to reach from under the T Piece and have the mouthpiece reach the divers mouth comfortably without effecting his ability to turn and move his head CCR divers who are accustomed to short loop hoses must understand that this is not a CCR but is new technology that works differently then a CCR Those of us who are experienced with bot
