Congratulations on purchasing the JJ-CCR Rebreather. We are certain that you will experience many un- forgettable dives using this equipment. The development and testing of the JJ-CCR Rebreather started back in 2006. During this period the equip- ment was able to demonstrate exceptional reliability over more than 1500 diving hours at a wide range of locations around the world prior the first public release.
• Independent HUD (Head Up Display) with real-time display of PPO2 for all three oxygen sensors. • Reliable controller with an integrated multi-gas decompression computer (based on the Shearwater Petrel 2). 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
Dives exceeding a depth of 100 m are associated with numerous additional risks Air: DIN EN 12021 Purity of the gases Oxygen: >99.5% (medicinal oxygen) Helium: >99.996 Atmospheric pressure range 800 – 1050mbar 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
Therefore it is not possible to specify exact numbers. 3.2.4 High-pressure oxygen The JJ-CCR uses high pressure oxygen as one of its supply gas mixtures. The related parts has been cleaned and prepared specifically for use with high-pressure oxygen. The diver must taken special care. Especially when filling the oxygen cylinder.
3.2.5 Expected inspired gas concentrations The oxygen setpoint range of the JJ-CCR is from 0.4 to 1.5 bar (low and high). The setpoint range cre- ates breathing gas mixture representing an inspired oxygen partial pressure between 0.4 bar and 1.5 bar.
Assembly of the JJ-CCR This chapter deals with the basic assembly of the JJ-CCR Rebreather. The equipment is fully assembled at the time of delivery. This chapter is primarily intended to show how the basic assembly takes place. At the same time, it acts as a guideline for correctly reassembling the equipment if it proves necessary to disassemble it for any reason (e.g.
The heavy duty stand is secured to the base plate of the base unit with 4 lock screws. The stand prevents the JJ-CCR from falling and can also be used as a fastening point for stages, wheels, buoys, etc. whilst diving.
It is now possible to tighten the self-locking nuts. The following im- age shows the stand correctly attached. All parts are shown once again here in overview. 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
The next assembly step concerns the 1st stages and hoses (low pressure and high pressure). When de- veloping the JJ-CCR, extensive value was placed on clear and simple hose guidance. A further primary objective was to ensure that the equipment was fitted with the minimum possible number of hoses.
ATTENTION: Never attempt to lift the equip- ment using the ADV or T-piece. This can cause serious damage to the counter lungs! 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
A washer and wing nut are attached to the backplate. From time to time it is necessary to check whether the wing nut requires tightening, or if it has loosened at all. 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
The harness is supplied fully assembled together with the back plate. However, it is essential that the harness is adjusted to the physical dimensions of the diver. The JJ-CCR Rebreather must always sit as high as possible on the diver’s back. It is also necessary to ensure that the equipment sits as tight to the back as possible.
Connecting the supplemental valves The JJ-CCR comes with two suplemental valves. The oxygen valve enables the manual supply of oxygen via the t-piece into the breathing circuit. The diluent valve enables the supply of diluent via a second con- nection on the ADV into the breathing circuit.
4.11 Soda lime canister (axial) The JJ-CCR Rebreather is supplied with an axial soda lime canister. 1. Take a water-resistant dust filter 2. Fill the soda lime canister until and place it in the base of the soda approx.
The pressure plate must be flush with the soda lime canister. The soda lime canister is correctly filled if shaking it does not result in noise being heard from the soda lime. 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...

Main components This chapter provides descriptions of some of the main components of the JJ-CCR Rebreather and also includes a few essential maintenance and care instructions. The lid with the three oxygen sensors, solenoid, battery com- partment, and connectors for controller and HUD is effec- tively the brain of the JJ-CCR Rebreather.
5.1.2 Oxygen sensors The JJ-CCR Rebreather uses three JJ-CCR oxygen sensors. The sensors can be exchanged in seconds with- out the use of a tool. IMPORTANT: Only use sensors of type ”R17JJ-CCR”! The shelf live is 3 months and max.
For a detailed description of the controller refer to the chapter 6. HUD (Head Up Display) The JJ-CCR Rebreather is supplied as standard with an HUD (Head Up Display). The HUD functions fully independently of the controller. This means that it uses its own DiveCAN® bus, electronic and power supply.

ADV (Automatic Diluent Valve) The JJ-CCR Rebreather is supplied with an ADV. The ADV works in a similar way to a 2nd stage and supplies additional diluent to the breathing circuit if necessary. This is the case for exam- ple if considerable negative pressure exists in the breathing cir- cuit.
Controller The JJ-CCR Rebreather is supplied with a controller, which contains a multigas (nitrox, trimix, heliox) and multimode (Open and Closed Circuit) decompression computer. The firmware installed on the controller is optimised for the JJ-CCR Rebreather and contains capabilities and functions developed specially for the equipment.
• Display can be rotated through 180 degrees • Very simple menu guidance with adaptive menus • Firmware update can be carried out by the user (via Bluetooth) 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
DiveCAN Architecture DiveCAN® is a digital communications standard developed specifically for rebreathers. The JJ-CCR uses two independent DiveCAN® busses. The handset (controller) is connected via the control bus to the SOLO board (Solenoid and Oxygen controller). The HUD uses the monitor bus and is connected to the Oxygen board (OBOE).
Turning on the controller In order to turning on the controller press both buttons at the same time. The JJ-CCR logo appears for a brief time, following by the controller’s main display. • For divers at high altitudes the surface pressure is determined by the following: When in sleep mode (off), the pressure is sampled every 10 seconds.

Checklist prior to diving This chapter contains a complete checklist for the JJ-CCR Rebreather prior to a dive. It is essential that the diver run through this checklist prior to every dive. • If the diver does not run through the checklist then there is a possibility of entering the water with equipment that is not suitable for diving, which can result in severe risks to health.
Check the display on the controller and HUD. Check that the equipment is correctly positioned and that everything is stored in the right place. 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
Diving The most important rule when diving is: Always know your PPO2 at all times! With the JJ-CCR this can be read out from the HUD and/or the controller. In order to be certain that both systems are working correct- ly, the diver should also check regularly to ensure that both instruments are displaying the same values.
Leave the lid and the soda lime canister to dry. Remove the counter lung with the breathing hose. Spray a little disinfectant (e.g. JJ-CCR Clean) into the T-pieces. Fill the counter lung and breathing hose with water and wait a few minutes (in accordance with the specifica- tions for the disinfectant).
Maintenance 14.1 General Care As with all technical equipment, the JJ-CCR Rebreather should always be treated with care. General care also includes observing the maintenance intervals and regularly checking the general condition of the equipment. For example, the O-ring grease.
If used within chlorinated water (swimming pool), it has to be cleaned with fresh water right away. 14.5 Maintenance Intervals The JJ-CCR Rebreather must be maintained in accordance with the maintenance intervals specified. • The user is permitted to replace the O-rings for the breathing circuit, the lid, base plate, shutter valves, oxygen sensors and membrane for the ADV.
Every 60 Months Part or Assembly Maintenance Task Return the equipment to the manufacturer or an approved service centre JJ-CCR Rebreather for a general service. ALWAYS KNOW YOUR PO2 2017 JJ-CCR ApS – 2.00 / Revision 06 JJ- CCR Ap S 2017...
