Locate the two counterlungs and their respective water diversion manifolds (also known as
“shoulder ports” or “T ports”) and lay those out for assembly . The purpose of these manifolds
is to prevent water that collects in the counterlungs from reaching the gas processor. The
water diversion manifold at the top of each counterlung diverts water coming from either of the
front breathing hoses into their respective counterlungs. Because of the direction of breathing
ow and the one-way mushroom valves in the mouthpiece, almost all water that leaks into the
mouthbit collects in the right counterlung, where it can be dumped via the checkvalve port at
the bottom of the counterlung (Figure 1-24).
Figure 1-24.
Clockwise tighten the water diversion manifold into the right and left
counterlung shoulder port.
4. Rear CC hoses to counterlung
T-connections.
Connect the T-connection to the top port in each counterlung.
Figure 1-23. Insert the right hand water diversion
manifold into the port on the right counterlung.
