    Risks against which the PPE is intended to protect The JJ-CCR rebreather is a respiratory protective device intended for diving purposes only. The JJ-CCR rebreather make it possible to supply the user with a breathable gaseous mixture under foreseeable con- ditions of use and taking account in particular of the maximum depth of immersion.

  • Page 8: Introduction

    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.

    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.

  • Page 12: Expected Inspired Gas Concentrations

    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.

  • Page 13: Assembly Of The Jj-Ccr

    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.

  • Page 14: Handle

    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.

  • Page 15: Attaching The Stand To The Base Unit

    The following im- age shows the stand correctly attached.     All parts are shown once again here in overview. 2022 JJ-CCR ApS – 3.00 / Revision 00 J J -CCR A pS 20 22...

  • Page 16: St Stages And Hoses

    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! 2022 JJ-CCR ApS – 3.00 / Revision 00 J J -CCR A pS 20 22...

  • Page 18: Backplate And Harness

    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. 2022 JJ-CCR ApS – 3.00 / Revision 00 J J -CCR A pS 20 22...

  • Page 19: Adjust The Harness

    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.

  • Page 20: Connecting The Supplemental Valves

    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.

  • Page 27: Main Components

    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.

  • Page 28: Oxygen Sensors

    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. The three cells are numbered (1, 2 and 3). These numbers can be found adjacent to the connection on the lid and above each cell.

  • Page 29: Solenoid

    5.1.3 Solenoid The JJ-CCR Rebreather uses a special solenoid, which is characterised in particular by its extremely low power consumption. With this solenoid the defective operating state is always in the closed position – this dramatically reduces the potential for oxygen poison- ing in the event of a malfunction.

  • Page 30: Controller

    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.

  • Page 38: Adv (Automatic Diluent Valve)

    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.

  • Page 39: Controller

    Controller The JJ-CCR Rebreather is supplied with a controller, which contains a multigas (nitrox, trimix, heliox) and multimode (Open and Closed Circuit) dec (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.
