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.
The optimum water position requiring the minimum breathing effort is at an angle of 20 - 30 degrees.
This means that the head must be somewhat higher than the legs. Breathing should be deep and even at
all times. In general terms, the volume in the breathing circuit should be as low as possible. Too great a
volume has a negative effect on the breathing effort and buoyancy. The volume in the breathing circuit is
perfect if breathing in does not quite trigger the ADV.
This chapter contains details of all steps that should be carried out with the JJ-CCR Rebreather after the
dive. Please carry out these steps after every dive:
It is possible to carry out ”quick” or ”complete” cleaning of the JJ-CCR Rebreather. ”Quick” cleaning is
completed rapidly and can also be carried out between two dives.
The following steps should be carried out for ”quick” cleaning:
Steps 5-8 are only necessary if the diver is planning no further dives the same day.
12.1 “Quick” Cleaning
Step
Description
1
Never close the tank valves before you take off the Rebreather.
2
Switch the controller off and dry the water contacts.
3
Switch off the HUD.
4

5
Remove the breathing hose with the DSV.
6
Remove the lid with the soda lime canister from the aluminium housing.
7
Remove the soda lime canister from the lid.
8
Leave the lid and the soda lime canister to dry.
Step
Description
1
Remove the breathing hose with the DSV and rise it with water. Attention: Excessive water pressure must be
avoided as this can damage the shutter valves.
2
Add water to the counter lung via the T-piece – ATTENTION ONLY ON THE EXHALATION SIDE. Remove the
water by actuating the fast drain valve.
3
Remove the lid with the soda lime canister from the aluminium housing.
4
Remove the soda lime canister from the lid.
5
Leave the lid and the soda lime canister to dry.
