Power Inflation with the i3 Control Unit

For the power inflator to operate, the MP inflator hose must be connected (see “Routing and Attaching the MP Inflator Hose”). After the hose is attached to the i3 Control Unit, pressurize the first stage regulator by slowly opening the cylinder valve.

To inflate your BC with air, lift up on the lever of the i3 Control Unit. Do not hold the lever up continuously underwater, as this could cause you to become excessively buoyant. Instead, inflate the BC in short bursts until you become neutrally buoyant.
warning WARNING: Avoid using excessive torque when lifting the lever of the i3 Control Unit.
warning WARNING: Do not rely on the i3 Control Unit as the only means to inflate your BC. It is important to practice the technique for orally inflating your BC so that you are prepared for any type of malfunction or out of air situation that could render the i3 Control Unit inoperable. You may otherwise be unable to achieve positive buoyancy in an emergency, which could lead to serious injury or death.
