2. Assembly Technical 60 m Counterlungs to  

BCD / Harness / Regulators

Attach the counterlungs to the shoulder straps of your BCD/Harness using the velcro straps
on the back side of each counterlung.

Upper counterlung shoulder strap to tank band connection.

Connect the small male plastic clip on the upper part of the counterlung to the female plastic
clip attached to the tank strap on the same side as the counterlung.
Adjust the position of the counterlung using the strap on each male plastic clip.

The counterlungs on the Poseidon SE7EN are designed to attach to the backpack straps and 
to be moveable along the straps. An upper adjustable-length quick connect buckle anchors 
the top end of the counterlungs to the gas processor (Figure 1-16). Three velcro straps on the
back of each counterlung (Figure 1-16) attach the counterlungs to the shoulder straps of the
backpack. The SE7EN is provided with a lower D-ring and a crotch strap that connect to the
bottoms of each counterlung. Using this system the user can fix the counterlungs as high or
low on the harness straps as desired to reduce the work of breathing.
