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.
The 1st stage with the M26x2 connection and the green pressure gauge is used for oxygen. A low pressure
hose line delivers the oxygen for the solenoid and the second hose is connected with the manual supple-
mental oxygen valve. The oxygen pressure relief valve triggers if the medium pressure rises to 10 bar, and
thereby prevents the hoses from rupturing if, for example, icing up should occur. The 1st stage with the
DIN 5/8” connection and the black pressure gauge is used for diluent. From the 1st stage a hose goes to
a small 3-way manifold. Here, the three hoses are connected with the ADV, manual supplemental diluent
valve and wing inflator. The diluent pressure relief valve triggers if the medium pressure rises to 15 bar,
and thereby prevents the hoses from rupturing if, for example, icing up should occur.
The image to the left shows how the first two stages are connect-
ed to the diving tanks. Arrangement of the high pressure and low
pressure hoses differs! It is very important to ensure that the hoses
are arranged as shown in the image!
The image to the right shows
the correct position of the
3-way manifold, which must
lie flush with the housing.
