Mounting Frame

The mounting frame used on the O2ptima allows the use of most

cylinders up to a length of 15 inches (38cm) and a diameter of 5.5

inches (14cm). The total overall length including the valve can be

approximately 19 inches (48 cm). The O2ptima is available with

several different cylinder options. The frame is made from a sturdy

light weight ABS plastic, with a stainless steel reinforcement bar

running down the center. The bar features two pre-threaded holes

at industry standard spacing for attachment to a backplate or soft

harness, plus additional non-threaded holes for mounting the

adjustable protective bottom/stand. The cylinders are mounted to

the frame using a removable Remora/cylinder bracket, and the

scrubber canister is secured using an elastic strap and buckle. The

back side of the frame has a nylon cover with a carry handle and

fastex buckles for securing the protective cover.

Protective Cover

The O2ptima FX uses a lightweight protective cover that allows

independent access to the canister and the cylinders. The canister area of

the cover has two weight pockets that are used to adjust the diver’s trim.

The pockets are capable of holding up to 5 lbs (2.3 kg). The cover is

secured to the mounting frame by nylon straps and Fastex style quick

disconnects.

Cylinders and Valves

The diluent cylinder is located on the left hand side of the diver

using a left handed DIN valve while the oxygen cylinder is located

on the diver’s right using a right hand DIN valve (traditional

configuration). The diluent valve is color coded BLACK with the

oxygen valve color coded GREEN.

The oxygen cylinder and oxygen components, such as the first

stage, hoses, SPG and addition valve, are oxygen service rated

when shipped from the factory. Normally the cylinders should be

internally inspected at once a year, but cylinders that are frequently

de-pressurized for shipping, or exposed to the atmosphere without

valves must be examined more frequently.
