Check before dive
Slowly turn on the air
1. Test the IF-O for inflation and deflation.
2. Fully inflate the BCD and leave inflated for a few minutes to check
for leaks around the corrugated hose and fittings.
3. If there was a cable dump attached to the IF-O, fully inflate the BCD
and pull the corrugated hose to check for proper operation.
4. Check the breathing operation of the IF-O regulator.
Dive operation
Operation of the IF-O is the same as any conventional
inflator
Breathing
The
IF-O
breathes like any conventional second stage. Clear the
IF-O
of water by first exhaling or using the purge button (front cover), then
breathe normally through the mouthpiece.
1. Power inflation is done by depressing the smaller, oval shaped
inflation button
2. Deflation is done by holding the
IF-O
overhead and partially
depressing the larger deflation button.
3. Oral inflation is done by fully depressing the deflation button and
exhaling air into the mouthpiece. Fully depressing the button seals off
the regulator exhaust valve and directs the exhaled air into the BCD to
inflate it. Release the deflation button to keep the air in the BCD.
