Manual addition
The additional ports on the counterlungs can be used for Oxygen and Diluent manual gas
addition valves for technical diving capabilities. These valves can be replaced with blank covers
if manual gas addition capabilities are not required (e.g., for recreational diving). The port for
the manual Oxygen addition valve (right counterlung) is intentionally placed higher than the
diluent addition valve (left counterlung). This forces the diver to think prior to manually adding
oxygen to the unit.
Manual addition O2
The manual oxygen valve on the right counterlung allows you to add oxygen into the loop when
attached. It will feed in more oxygen the longer the button is pressed.
WARNING:
Manual additions requires adequate training and can cause
serious injury or death if not used correctly.
Manual addition Dil
The manual diluent valve on the left counterlung allows you to add diluent into the loop when
attached. It will feed in more diluent the longer the button is pressed.
Figure 3-41.
Remove the blank port plugs on each counterlung
and replace them with the manual addition valves.
