Component Assembly and Checklists

The O2ptima FX has been designed for easy assembly and disassembly. All the components of a

completely disassembled unit (less cylinders) fit into the main body (mounting frame plus

protective cover) of the rebreather. The Optima FX is shipped from the factory in this configuration

and is ideal for long term storage and for protection during travel.

Cylinders, Regulators and Hoses

The first task is to mount the valves to the cylinders. Inspect the valves and tank neck O-rings.

Lubricate the tank neck O-ring and threads with Christolube MCG 129 or equivalent. The oxygen

valve is a 300bar DIN valve with a GREEN knob and the diluent cylinder is a 300bar DIN valve

with a BLACK knob.

The next task is to mount the Remoras to the cylinders, proper

orientation of these brackets is important. The cylinders can be

mounted using stainless steel hose clamps or by using cam straps with

buckles (see next page). Loosely position the Remoras in the

approximate center of the cylinders. The Remora with the locking pin

should be mounted on the oxygen cylinder with the remaining

Remora mounted to the diluent cylinder. The locking pin and the

receiver on the diluent Remora should be facing the valves. Install

the cylinders on the mounting frame by sliding the Remoras onto the

mounting bolt. The valves should be facing the base with the

regulator connection facing up, adjust the position of the Remoras to

fit the cylinders as necessary.

The regulators should now be mounted on the cylinders to determine the final positioning of the

Remoras. The diluent regulator should be mounted on the diver’s left and the oxygen regulator on

the diver’s right. Adjust the Remoras to allow a gap of 0.25 inches (6mm) to 0.50 inches (12mm)

between the regulator and the base and tighten the hose clamps to secure the cylinders in place.

This gap is necessary to provide protection to the regulators should the base flex when weight is

applied. Secure the Remora/cylinder assembly in place with a washer and wingnut.
