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. On the right hand
side is the connection for the low pressure oxygen hose to
the solenoid. Under the cap engraved with ”JJ-CCR” is the
battery compartment.
IMPORTANT:
The lid should always be treated with the
utmost care.
5.1
Lid
In order to open the battery compartment it is necessary to
remove the 10 screws from the battery compartment. The JJ-
CCR Rebreather has an extremely low energy consumption.
The batteries usually have a lifetime between 6 to 12 months.
A design feature of the JJ-CCR Rebreather is the arrangement
of the batteries. As shown in the image, no batteries are in-
tegrated into the breathing circuit and the battery compart-
ment is completely sealed. As such battery problems never
arise due to increased moisture, which would have been the
case within the breathing circuit. Furthermore, the batteries
are not exposed to any pressure changes in the battery com-
partment. Problems with batteries, that may be attributed to
severe changes in pressure, are therefore fully excluded with
the JJ-CCR Rebreather. Due to the complete sealing of the
battery compartment, a fully flooded breathing circuit will
also have no effect on the batteries. The two 2 x 9v block
lithium batteries are used in parallel for the solenoid. When
replacing the batteries please always change both batteries!
The current voltage of the batteries can be checked on the
status display on the controller. The controller also issues an
external battery warning (Low Battery EXT) if the voltage is
too low. The 3.6v lithium battery (SAFT 14500) is for the HUD.
Please ensure that the battery is inserted correctly into the
battery holder. The battery holder is appropriately marked
with ”+” and ”-” signs. It is recommended that the battery
for the HUD always be replaced at the same time as both
batteries for the solenoid.

IMPORTANT:
Only 9 volt block batteries
with rounded edges will fit.
