2. User Guide
The O2ptima CCR was designed to ensure assembly and disassembly of the unit is
straightforward and simple.
WARNING: THE FOLLOWING INSTRUCTIONS ARE ASSEMBLY INSTRUCTIONS
ONLY. FURTHER TRAINING IS REQUIRED PRIOR TO USING THE UNIT.
INITIAL ASSEMBLY IS TO BE COMPLETED UNDER THE SUPERVISION OF THE
CERTIFYING O2PTIMA INSTRUCTOR.
2.1. Breathing Loop Assembly
The breathing loop can be divided into four separate items (inhalation side, exhalation side,
canister, and mouthpiece/DSV). When assembling the breathing loop ensure that all hose
fittings have been lubed with oxygen compatible lubricants in order to protect the o-rings.
All connectors should only be finger tight. Over tightening can result in damage to the
threads and o-rings.
All the inhalation connectors are color coded and thread matched to ensure that the
components are assembled in the appropriate location with respect to the exhalation side.
