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.
The product development philosophy is aligned with the following criteria:
• Strict application of the KISS principle: ”Keep It Simple Stupid”.
• The Rebreather must be extremely solid, versatile and reliable.
• The Rebreather must be very simple to use, maintain and service.
• The use of easy to obtain parts, enabling on-site repairs at any time.
• The support of a wide range of tank sizes without requiring any special adjustments to the
equipment.
• The supply of fully operational equipment and not basic equipment with numerous different
options.
• The equipment must be configured to include a very high level of redundancy. For example,
separate batteries for the controller, HUD and solenoid. No batteries are permitted within the
circuit. And it must be possible at all times to manually operate the Rebreather in the event
of the controller failing.
• The use of simple and above all reliable electronics. No use of any high tech gimmicks and
strict avoidance of an ”autopilot effect”. The diver retains full control of the Rebreather and
not vice versa.
• Availability of scientific test records in order to verify the equipment performance.
• Always on the search for new ways of further improving the equipment.
