Inspect the o-ring on the end-cap and lubricate if necessary. Locate

the water trap, inspect the o-ring for debris and damage. Lubricate

the end-cap o-ring surface and press the water trap into place. The o-

rings from the end-cap and water trap should line up next to each

other when the water trap is properly installed.

Canister Assembly

The ease in assembling of the canister is a feature that sets the

O2ptima FX apart from other CCRs and is big step in improving

diver safety. Assembly starts by inspecting the o-rings on the head.

They should be free of debris and exhibit a uniform shiny appearance.

A flat appearance indicates that the o-ring is dry and some lubrication

is necessary. Only use enough lubricant to protect the o-ring from

drying out. Thick lubrication does not improve the seal, and

increases the chance that the o-rings will become dislodged.

The center body now should be installed. There are arrows and

markings on the center body and head indicating the locked and

unlocked positions. Press the center body into the head and rotate

until it drops into place, now rotate clockwise until the arrow lines up

with the LOCKED position.

Inspect packaging for damage and verify cartridge expiration date.

Remove a fresh ExtendAir Cartridge from its packaging and inspect

cartridge for damage. Verify cartridge expiration date and remove the

red cap. Place the cartridge onto the oxygen premix tube and firmly

press the cartridge into the head. Make sure the grommet on the o2

tube is firmly against the cartridge. If the cartridge is removed

between dives, it must be reinstalled with the same orientation as in

the original dive.
